Widuf Privacy Policy

Version 3.2 · effective from [EFFECTIVE DATE]

Widuf is an app for parents and guardians: it brings together your child's class timetable, tests, grades and class lists in one place. In classes in Chile, from 5th grade (5° básico), if you invite them, your child can have their own student account, a limited view that you control (section 11). To do all this we need to process data about you and your children, who are minors. Here we explain which data, what for, who sees it, how long we keep it and how you control it.

This policy is available in Spanish and English. Both versions have the same value; if they differ, the one more favourable to you applies.

If you are a student, read the part "If you are a student" in section 11 first: it is written for you.

1. Who is responsible for your data

• Controller: [COMPANY NAME], Chilean tax ID (RUT) [TAX ID].
• Address: [ADDRESS], Chile.
• Email for privacy matters and to exercise your rights, in Spanish or English: soporte@widuf.com.

Widuf is offered from Chile to parents in several countries. We apply Chilean data protection law (Law No. 19,628 as amended by Law No. 21,719) and also the data protection law of the country where you live: if they require different things, we follow the one that is stricter in your favour.

2. What data we process

Your account

• First name, last name and email. Phone number, only if you add it.
• Your country, which you choose when you sign up, and the app language. We do not ask for your city, region or address.
• Your password, stored with one-way encryption (nobody, not even us, can read it).
• If you sign in with Apple: the identifier and email Apple gives us (it may be an Apple private relay email) and your name if you choose to share it.
• That you declared you are of legal age and that you authorised the processing of your children's data, with the date, version and language of the text you accepted; and, if you request it, the date you asked to delete your account.
• If you turn on "Keep the folder" (section 9), the date you did it or turned it off and the version of the text you accepted.

Your children and your classes

• School (with its country and city), grade and section of each class you belong to, your role and whether you manage the class. If the school is not on our list, you create it with its name and city, and it becomes available to other families of that school.
• Your child's first and last name, and the class they are in.
• Requests to join a class (with your child's name and any message you write).

Syllabus and reading list

• An assessment's syllabus: the text (up to 2,000 characters) and up to 3 photos uploaded by a parent in the class, and who uploaded it. A photo of a notebook or worksheet may show a child's handwriting or name: before you upload it, the app asks you to cover or crop names, grades and children's data.
• Reading list: the class's list of readings (title, author and date) entered by parents, and what you mark as read for each child. We do not store books or pages of books.

Assessments and grades

• Subject, date, type and title of each assessment.
• Your child's grade, whether you type it or the AI estimates it from a photo, and where it came from (you or the AI), on the grading scale of the class's country.
• Photos of tests you upload (up to the number per assessment set by the current figures). They make up each child's folder. They may show your child's handwriting, name, answers and the teacher's corrections. We keep a compressed copy, not the original file.
• What the AI reads in those photos: possible student names, the grade, how many questions were right, wrong or left blank, and a short analysis of what to reinforce. The analysis is stored with your child's grade, without the names the AI read.

Class timetable and calendar

• Photos or files (image, PDF or Excel) of the timetable and test calendar uploaded by whoever manages the class, and the blocks and dates extracted from them.

Class lists

• Lists created by whoever manages the class: collections ("cooperaciones") and lists of things to bring ("Who brings what?"). For each list we store its title, purpose, deadline or date, place, who created it and whether it is visible to students.
• What you mark on them: that you contributed, when and how (and the amount, if you enter it), and which item you took. Also how you choose to appear: with your name or as "Family of" your child.
• If you receive the money of a collection: the transfer details you enter (account holder's name, identification number, bank, account type and number, and email if you add it). If you choose, we keep them in your profile to prefill your next collection; you can delete them at any time.

• If you wish, your transfer receipt: an image or PDF that may show your name, identification number, bank and account number, and those of the recipient. It is optional.
• In "Who brings what?" lists, if you wish, a photo of what you are bringing and the "Brought" mark.
• If you receive the money of a collection, what you write when closing it to report how it was spent. If you name a co-organiser, their name and whether they accepted.
• Widuf does not receive, hold or transfer the money of collections. We do not ask for bank details to contribute.

Data about other people shown in a class

• Names and subjects of teachers, and class events, entered by parents.
• Class committee (name, role, email and phone) and the class bank account (holder, identification number, bank, account type and email), only if the class asks us to publish them.
• If you enter someone else's data, ask for their permission first.

Your phone

• Notifications: if you turn them on, we store your phone's notification identifier (token), whether it is an iPhone or Android, the app language and which types of notice you want, with your account, to tell you when someone else changes something in the class: the timetable, assessments, class lists and, if you manage the class, join requests. You choose which types to receive in Profile → Notifications. Notices never include anyone's name, grades, amounts, titles written by others or details of a contribution.
• Assessment reminders (on; you turn them off in Profile → Notifications): using the dates of the assessments you see and the time zone of the class's country, we remind you one week before and the evening before, and the week before a reading on the reading list; at most one notice of this type a day and never between 21:00 and 8:00. We record which reminder was sent, so it is not repeated.
• "Widuf gifts and news" (off until you turn it on): if you turn it on, we store the date, version and language of the text you accepted, and the date you turn it off.
• When you use the camera or gallery, we only receive the photos you choose to upload. We do not access the rest of your gallery or your location.
• Share with Widuf: if you share an image or PDF from another app (for example, a receipt from your banking app), we only receive that file, and only when you choose which list or section it goes to. If it is a test or a timetable, we first ask for your AI permission (section 4).
• The photos you upload reach our server without the hidden data they carry, such as location.

App usage

• Which screens you open and what actions you take (for example, "uploaded a timetable"), without names, grades, amounts, texts or photos, to know what works and what to fix. It is stored on our own servers; we do not use third-party analytics or advertising tools.
• How many AI analyses you use each month, what each one cost, whether a plan or a gift paid for it and, if a plan, for which child, and which gifts you received (gift months of Plus, Widuf gifts and monthly rewards), why you got them, until when they are valid and how much of each you used, to apply the plan's pool, the gifts and the cost limits; and how many times you read the timetable or the calendar with AI and what it cost, for its upload limit and the cost limit. It does not include the content of photos or grades.
• The Widuf inbox: the messages Widuf sends you in the app (gifts with their conditions, and news) and whether you opened them. They never contain your children's data.
• If you object to Widuf gifts and rewards (section 3), the date you did so.
• Plans: which children a plan covers and until when. A plan covers children, not accounts: it is used by the parents linked to those children (section 5).
• If you subscribe to Widuf Plus (bought inside the app and charged by Apple on iPhone or Google Play on Android): an internal code for your family that does not say who you are (the one the app passes to the store and to RevenueCat when buying), the store, the option you chose (for how many children), which of your children it covers, the subscription status (active, in grace period, paused after a failed charge, cancelled, expired, refunded), the start, renewal and end dates, whether it will renew, and what the store tells us about each purchase or renewal: its code, product, date, store country, price and currency, whether it was refunded or voided and why, and whether it was a test purchase. We also keep a log of each change, without your children's names. We never receive or store your card details, Apple ID or Google account: the store holds those.
• What you write to us: messages you send from Profile → Tell us something and content reports, with the screen and app version. We use them to reply to you and to moderate.
• Server technical logs (IP address, date and page requested), for security.

Your child's student account (only in classes in Chile), if you invite them: their first name (the one you already entered), month and year of birth, their sessions on up to two phones and, only if you allow it, the token to notify them and the photos of their tests. Details in section 11.

What we do not ask for: your children's national identification number (such as Chile's RUT), their full date of birth (for the student account, only month and year), your address, your location, health data or your phone contacts. Your child does not give us an email, password, phone number or photo.

3. What we use it for

1. To provide the service: create your account, join a class, show you your children's timetable, tests and grades. Your country is used to apply the law that applies to you (minimum age, rights and the authority you can complain to), the grading scale and your classes' school year.
2. To read the photos you upload. An AI reads the timetable or calendar photo to organise blocks and dates, and a test photo to suggest the grade and a short analysis. You review it and can correct the grade. It is an aid: it is not the official grade, it does not replace what the school says, and no decision about your child is made with it. If a test's analysis has to wait (because it is queued or until you have an analysis), the photo stays only on our server and is sent to the AI only when it is analysed; if queued, by the next day at the latest. Waiting does not extend how long we keep the photo (section 9). If you withdraw your AI permission, delete the test or delete your account first, it is not sent.

1. To notify you of class changes and remind you of upcoming assessments and readings, if you turn on notifications.
2. To coordinate the class: so parents can organise collections and lists of things to bring without message chains, and share an assessment's syllabus and the reading list.

1. To improve the app and detect errors, with usage data on our servers.
2. Security and sustainability: prevent abuse, apply the AI analyses of your plan and your gifts, usage limits and cost limits, and protect accounts.
3. To reply to you when you write to us and to review reports.
4. To keep each child's photo folder during the school year and, if a plan covers the child and you ask with "Keep the folder", for longer; and to warn you before each automatic deletion.

1. To apply plans to the children they cover, without showing other parents who paid.

If you subscribe to Widuf Plus: to verify with Apple or Google, through RevenueCat, each purchase, renewal, change, cancellation and refund to turn Plus on or off for the children it covers, send you a copy of the terms you accepted, handle your complaints and meet tax obligations.

1. To give your child their student account (only in Chile), if you invite them: show them their timetable, assessments and grades and, if you authorise it, generate AI study guides.

1. To give you Widuf gifts (AI analyses), with published conditions, and tell you about them in the inbox and, only if you turned it on, with "Widuf gifts and news".

Widuf gifts and rewards. To choose who gets a gift we only use data from your account: your country, your classes and schools (with their grade level), whether you have Widuf Plus, how long you have had your account and what you do in the app, counted from what is stored in the service (for example, that you uploaded the calendar or a syllabus, that a family you invited with the share link joined, or how many months in a row you used Widuf), not from the usage data in section 2. We never use your children's grades, photos, analyses, age or any of their data, or whether they have a student account, and we never reward grades. Monthly rewards are given automatically to whoever meets rules we publish in Profile → AI analyses, with their dates, the same for everyone; a Widuf gift is given equally to every account in a group (a country, a school, a class). They only decide whether you receive AI analyses as a gift: they take nothing away and do not change the price, your allowances or the service. In our team we only see how many accounts receive a gift, never which ones. You can object in Profile → "Widuf gifts and rewards": from then on you are left out of group gifts and rewards, without losing what you already received or anything of the service. Student accounts never receive gifts, rewards or inbox messages.

We do not sell your data or your children's data. There are no third-party ads in the app and we do not build profiles for third parties. We do not use your data or your children's data to train AI models.

4. Legal basis

• Your account and the service: the contract you accept when signing up (the Terms of Use).
• Data of your children under 18: your consent as their parent, legal guardian or person with legal custody. When you create your account you declare that you are, and that you are of legal age in your country, and you authorise us to process your children's data as this policy explains. We ask for it for every child under 18, even if the law of your country sets a lower age.
• AI reading of photos: your specific consent, which we ask for in your language before the first photo, and which includes the transfer to the United States (section 7).
• Notifications: your phone permission, which you can remove at any time, and your choice of which notices to receive. Assessment reminders are part of the service you request (the contract).
• "Widuf gifts and news" on your phone: your consent, which you give by turning it on after reading what you will receive, and withdraw with the same switch.
• Widuf gifts and rewards: our legitimate interest in giving you Widuf benefits using data from your own account, never your children's, with your right to object in Profile at any time (section 3).
• Syllabus and reading list: the contract (the Terms of Use); if you upload a syllabus photo, you do so after reading who will see it.
• Keeping the photo folder beyond the no-plan period: your consent, which you give by turning on "Keep the folder" in your child's folder (in Assessments) when a plan covers them, and which you withdraw just as easily with the same switch, which stays visible while the option is on, even if the plan has expired. If the plan ends, the option ends with it: if you get a plan again, it stays off until you turn it on again. We store the date, the version of the text you accepted and where you did it. Without it, photos follow the no-plan period even if there is a plan (section 9).
• Widuf Plus: the contract you accept when subscribing (verify the purchase, give you Plus, confirm it and handle cancellation and complaints); the legal obligation to keep sales records for the Chilean tax authority; and our legitimate interest in being able to answer a complaint about a charge while the law allows it.
• Our own analytics and security: our legitimate interest in the app working and being secure, without affecting your rights. You can object by writing to us.
• Your marks on lists and the transfer details you enter: the contract (the Terms of Use).

• Your child's name on a list, if you choose to show it: your consent as parent or guardian, which you give by choosing it and can withdraw by changing how you appear.
• Your transfer receipt and the photo of what you bring: your consent, which you give by attaching them after reading who will see them and when they are deleted.
• Student account (Chile only): your consent as parent, legal representative or person with legal custody, which you give when you invite them; from age 14, also your child's acceptance. The month and year of birth, to comply with the law according to their age.
• AI study guides: your specific consent for that purpose, separate from reading photos.

• Other people's data in the class: [LEGAL BASIS FOR THIRD-PARTY CLASS DATA].

If the law of your country requires a different basis for any of these, we apply the one it requires; if we cannot meet it, Widuf is not offered in your country (section 14).

You can withdraw your consents at any time (section 8). That does not affect what was done before, but without the AI consent we stop sending photos to the AI.

5. Who sees your data

• You see everything about you and your children.
• Your child's grades, photos and analyses are seen by you, the other parent linked to that same child in Widuf, if there is one, and your child, if you opened their student account (the AI-estimated grade, only after you confirm it). Other parents in the class do not see them.
• Assessments you create as "Only my family" are seen by you, the other parents linked to your children in that class and, if they have a student account, those children. Nobody else in the class. When you create one, the app tells you who will see it.
• Other members of the class see your name, your child's name, the timetable, the test calendar (subject, date and title), events, assessments that whoever manages the class marks for the whole class, and whatever has been uploaded for the class. Nobody in the class knows whether your child has a student account.
• If a plan covers your child, the parents linked to them see that they have a plan and until when, and use it for that child. Nobody sees who paid for the plan, how much, how, or whether it renews. If whoever paid stops being linked or deletes their account, the plan keeps covering the child until the end of the paid period. Your child never sees the plan.
• Your Widuf Plus subscription data (option, status, dates, renewal and changes) is seen by you in the app, and in our team only by those who handle payments, with each access logged.
• In class lists, all members see the items to bring, who took them and whether they were brought. What you contributed to a collection is seen only by you and the person receiving the money (and the co-organiser, if the recipient named one and they accepted: their name appears on the collection before you contribute); the rest of the class only sees how many families have contributed and, from 3 confirmed contributions, the confirmed total, without names or amounts per family. Your receipt and the photo of what you bring are seen only by you and the recipient or organiser (and that co-organiser); nobody else in the class, not even whoever manages the class. Transfer details are seen by class members while the collection is open. What the recipient writes when closing the collection is seen by the whole class.
• An assessment's syllabus is seen by whoever sees that assessment: in a "Whole class" one, all the class's parents; in a "Only my family" one, only those described in the point above. Your child, if they have a student account, does not see syllabus photos. The reading list is seen by the class's parents; what you mark as read for your child, only their family.
• Whoever manages the class also sees join requests and members' emails.
• We access the data only to run the app, provide support, review reports or solve a security problem.
• The school has no access to your data through Widuf.

6. Who we share it with

Only with providers we need to operate, who process the data on our behalf, under contract, and cannot use it for anything else:

RevenueCat in turn uses other providers in the United States (sub-processors), under its data processing agreement, which requires it to process the data only on our instructions.

Apple (App Store) and Google (Google Play), if you subscribe to Widuf Plus, charge the subscription on our behalf. They are not our processors for the charge: they process the data you give them to pay (your Apple ID or Google account, your payment method, your country) as controllers, under their own privacy policies (Apple and Google). We only pass them, through the app, the product you choose and an internal code for your family that does not say who you are, to know which Widuf account the purchase belongs to. We never send them your name, your email or your children's names, classes or schools. They tell us about each purchase as described in section 2, never your card or account details. We do not send them data about how you use the app to decide refunds.

Under OpenAI's API terms, it does not use what we send to train its models and keeps it for up to 30 days to detect abuse, unless the law requires it to keep it longer.

We would only hand data to an authority if a law or a court requires us to.

7. International transfers

Your data is stored in [SERVER COUNTRY] and, through the providers in section 6, travels to the United States. The United States has no general federal personal data protection law like Chile's; that is why we require each provider to sign a data processing agreement that obliges it to use the data only for what we ask and to protect it.

• Photos read by the AI go to OpenAI only with your express consent to that transfer, which we ask for before the first one, and OpenAI processes them under a data processing agreement that obliges it to use them only to answer our request. We only send what is needed to read the photo.
• Your phone's token and the text of each notice pass through Apple or Google to reach your phone.
• If you subscribe to Widuf Plus, you make the purchase directly with Apple or Google, who process it under their own policies; the only thing that leaves Widuf is your family's internal code and our requests to verify your purchase, which go to Apple, Google and RevenueCat. We do this because it is necessary to perform the contract you ask for.

If the law of your country requires another safeguard to transfer your data abroad and we do not have it, Widuf is not offered in your country until we do (section 14).

Receipts and list photos are not processed with AI.

8. Your rights and how to exercise them

You can, free of charge:

• Access your data and know how we process it.
• Rectify anything that is wrong: you correct your profile, your country, your child's name and grades in the app.
• Erase your data: delete an assessment with its photos using "Clear", or delete your whole account (section 9).
• Object to processing, for example to usage analytics, or to Widuf gifts and rewards (in Profile, section 3).
• Request portability: a copy of your data in a commonly used electronic format. You can download each child's folder (their photos and a spreadsheet with their grades) yourself, free, from the app (section 9).
• Request the temporary blocking of your data while we resolve a request.
• Withdraw your consent to AI reading of photos (Profile → AI permission), to keeping the photo folder ("Keep the folder"), to showing your child's name on a list, to your child's student account ("Remove access", effective immediately) or to the processing of your child's data. You turn notifications off, including "Widuf gifts and news", in Profile → Notifications or in your phone settings.
• Exercise any other rights the law of your country gives you.

Write to us in Spanish or English at soporte@widuf.com from your account email, saying what you need. We confirm we received it and reply within 10 business days, or sooner if the law of your country requires it. For blocking, we reply within 2 business days. We may ask you for something to confirm it is you.

If your child is 14 or older and has a student account, they can ask us themselves for a copy of their data or its erasure, by writing to the same email.

If we do not reply or you disagree with the reply, you can complain to the data protection authority of your country (in Chile, the Agencia de Protección de Datos Personales, from 1 December 2026) or to the competent courts.

9. How long we keep data

• Test photos without a plan: each child's photos make up their folder. Without a plan, they are kept until the last day of the month after the end of the class's school year in its country (in Chile, until the following 31 January: photos from a 2026 class, until 31 January 2027) and are then deleted automatically.
• Test photos with a plan: if a plan covers that child and you or the other parent turn on "Keep the folder", they are kept while the plan is active and the account of any of their parents exists. When the plan expires or the option is turned off, photos from previous years are kept 60 more days and then deleted. We do not keep them "forever". Each child's folder, in Assessments, shows until what date their photos are kept.
• Notice before deleting photos: before each automatic deletion we notify the child's parents in the app at least 30 days before and again 7 days before, with the date: from 30 days before, the child's folder shows how many days are left, and you also get a notification if you have Assessment notices turned on.
• Deleting them earlier and what we keep: you can delete them earlier with "Clear" (the child's other parents also stop seeing them) or by deleting your account. We keep a compressed copy, without the file's hidden data (such as location), not the original.
• Downloading them: you can download free, with or without a plan, each child's full folder (all their photos and a spreadsheet with their grades) with "Download folder", and each photo separately, whenever you want and before any deletion.
• The cut-off month and the 60 days are figures published on the Widuf website and in the app; if they change to your detriment, we notify you at least 30 days before.
• Grades and AI analyses: while you have your account, to show you your child's school history, even after the photos have been deleted. The analysis stored with the grade does not include the names the AI read in the photo. You can delete them with "Clear".
• Timetable and calendar photos and files: [RETENTION FOR TIMETABLE AND CALENDAR].

• Class lists: the receipt is deleted 24 hours after the recipient confirms your contribution (within that time they can undo the confirmation), or at the latest 30 days after the collection closes; we delete it immediately if you remove it, undo your contribution, or you or the recipient delete your account. The photo of what you bring is deleted 7 days after the activity date, or earlier if the list closes or you release the item. Transfer details are hidden when the collection closes and deleted 30 days later. The per-family detail is deleted 60 days after closing and only the total remains. Everything is deleted at the end of the class's school year.
• Notifications: your phone's token, while notifications are on and your session is open on it; it is deleted when you log out, delete your account, or Apple or Google expire it. For each notice sent we keep the text and whether it reached each phone for 30 days, to check failures; then it is deleted.
• Widuf inbox: each message, while it is valid and 30 days after; it is deleted when you delete your account. An unused gift expires on the date it states and is lost if you delete your account.
• Syllabus: deleted at the end of the class's school year, or earlier if whoever uploaded it or whoever manages the class deletes it. Reading list: [READING LIST PERIOD]; what you marked as read is also deleted when you delete your account.
• Student account: until you remove it, your child closes it or it ends on its own (section 11); sessions close after 90 days without use; the authorisation and its changes are kept 4 years after the account ends, without grades or photos.
• Usage data, messages and reports: [ANALYTICS RETENTION].
• Server technical logs: [SERVER LOG RETENTION].
• Your account: while you use it. If you delete it from the app (Profile → Delete account; more details at widuf.com/en/delete-account), it is deactivated immediately, your sessions are closed and you stop receiving notices. After 30 days we permanently delete your account, the data of your children you entered (if another parent is linked to your child in Widuf, their data stays in that account), their grades, photos and analyses, and your marks and transfer details on lists; your open collections are closed. If you managed a class, another member becomes its manager. Usage data is kept without your name or email. This cannot be undone.
• Widuf Plus: if you delete your account on Android, we cancel the renewal on Google Play before deleting it and there are no more charges. On iPhone we cannot cancel an Apple subscription: before deleting, the app warns you that Apple will keep charging you until you cancel it and takes you to "Manage subscription". In both cases your children stay covered until the end of the paid period. When we delete your account we ask RevenueCat to delete your family's record. We keep the record of each purchase, renewal and change (store, product, date, price, status and how many children it covered) ourselves for 6 years from 31 December of the year of each charge, because Chilean tax law requires it, even if you delete your account; from the moment you delete it, without anything that identifies you. Which account pays and which of your children it covered, up to 2 years from the last charge or from the closing of a complaint, whichever is later, so we can answer a complaint; then only how many remains. Copies of the notices Apple and Google send us, also 2 years.
• What you uploaded for the whole class (events, class assessments) stays in the class for the other members.
• Backups: we make a daily backup that is kept for 14 days; deleted data disappears from them within that time.
• We do not keep data we no longer use.

10. How we protect data

• Encrypted connection (HTTPS) between the app and our servers.
• Passwords stored with one-way encryption.
• Private photos and files only open with a temporary link generated for whoever has permission.
• Each parent only accesses their own children's data.
• Restricted internal access and daily backups.
• If a breach puts your data at risk, we notify the data protection authority of each affected country within the time its law sets and, if it affects children's or financial data, we notify you directly.

11. Children and teenagers

The parent account is for adults: to create one you must be of legal age under the law of your country, at least 18 years old, and be the parent, legal guardian or have custody of the child whose data you enter. We always process children's data with their best interests in mind: the minimum for you to follow their school year and coordinate with the class, never for advertising. Only upload photos of your own children's tests, and do not upload photos of what you bring that show children.

Student account (only in classes in Chile). Outside Chile it does not exist for now: we will open it in another country only after reviewing its law.

From 5th grade (5° básico) and age 10, you can invite your child to their own account. Before that age it does not exist. Only you, or the other parent linked to your child in Widuf, can open it, with a single-use code or QR that you generate in your app and that expires in 30 minutes. When you invite them you tell us that you are their parent, legal representative or have legal custody and their month and year of birth, and you authorise it: that is the consent Chilean law requires for children under 14, and we store it on our server with the date and the version of this text.

• From 10 to 13, your authorisation is enough: your child accepts nothing, but we explain in simple words what their account is and they tap "Got it".
• From 14 to 17, your child also accepts the Student Terms themselves and can exercise their own rights.
• At 18, the account ends, unless your child accepts the terms themselves within 30 days.

What data. Their account has no email, password, phone number or photo. We process their first name (the one you already entered), month and year of birth, their sessions on up to two phones and, only if you allow it, the token to notify them of changes and the photos of their tests. We do not keep usage data linked to their identity.

What they see and what not. Your child sees their timetable, the class assessment calendar, class events, their family's "Only my family" assessments, their own assessments, grades and analyses (the AI-estimated grade, only after you confirm it), their guides and the "Who brings what?" lists that whoever manages the class marked as visible, without other families' names. Titles and texts written by other adults pass through a filter: they cannot include phone numbers, emails, social media or links, and if they do not pass, your child does not see them. They never see anything about money, list photos, class members, other families or shops. Your child does not write texts; only if you turn it on can they upload photos of their tests (with your AI permission) and add upcoming assessments. Nobody in the class can write to them and nobody knows whether they have an account.

No ads or profiles. In their account there are no ads, purchases, prices or offers, and their data is not used for profiles, rankings or comparisons with classmates. AI study guides are generated only if you authorise them: the AI receives the subject, level and topics to reinforce, never their name or photos, and nobody decides anything about your child with them. What your child uses with AI is deducted from the plan that covers them or, if none, from the gift analyses of the parent who invited them, never from an allowance of their own; your child is never shown the plan.

Their account does not receive reminders, gifts, rewards or inbox messages, and your child's data is never used to choose who gets a gift.

You decide. You can see what your child sees, change their permissions, close their sessions on each phone and remove their access whenever you want, effective immediately. If your child has two parents in Widuf, both have the same rights: the last action counts and the other gets a notice. Your child can close their account from the app (we tell you) and, from age 14, ask us themselves for a copy of their data or its erasure.

When it ends. The account ends on its own if you delete your account, leave the class or unlink from your child (unless the other parent confirms it within 30 days), when the school year ends (unless you renew it) or when your child turns 18 without accepting the terms themselves. When it ends, their access and tokens are deleted; the grades stay in your account. We keep your authorisation and its changes as evidence for up to 4 years after the account ends, without grades or photos.

If a breach affects children's data, we notify you as their representative.

If you are a student. This part is for you.

• Your mum, dad or guardian opened your account. They see the same as you and can close it. You can close it too, in My account.
• We only keep what is needed to show you your timetable, tests, grades and guides. We do not keep what you do in the app, there are no ads and we do not sell your data.
• Nobody in the class can write to you here. If someone asks for your number or social media, or something makes you uncomfortable, tap "Something's not right" and tell your parent.
• From age 14 you can ask us for a copy of your data or to delete it, by writing to soporte@widuf.com.

12. Cookies

The app does not use advertising or tracking cookies. Widuf's legal pages do not use cookies or load third-party services.

13. Changes to this policy

Each version has a number and date, in Spanish and English, and we keep which version and in which language you accepted it. If we change something important, we tell you in the app before it takes effect and, if needed, ask for your consent again.

14. Countries and legal framework

Widuf is offered only in some countries: those you can choose when signing up. It is not offered where our model conflicts with the law (for example, where the AI service we use does not operate, where international sanctions reach our providers, or where the law requires data to be stored inside the country) nor, until we meet what their law requires, in other countries where we still have pending requirements. You may not use Widuf from a place subject to comprehensive sanctions.

This policy is governed by Chile's Law No. 19,628 on the protection of private life and, from 1 December 2026, by that same law as amended by Law No. 21,719 on personal data protection, and it also respects the data protection law of the country where you live.
