TONEC STUDY Privacy Policy

Effective date: November 3, 2026

TONEC STUDY ("TONEC STUDY", "the app", "we", "us") is an educational app where students practise school subjects. This policy explains what information the app and this website collect, why, how long we keep it, and how you (or, for a child under 14, a parent or guardian) can control it. The rules for using TONEC STUDY are in the Terms of Use.

1. Who is responsible

TONEC STUDY is developed and run by an individual developer, Antonio Kavaj, in North Macedonia (not a company). He is the controller of your personal data. For any privacy question or request, write to support@tonecstudy.com.

2. What we collect

You can use TONEC STUDY without an account: then your profile and progress stay only on your phone. With an account, they are saved online so they work on any phone you sign in on, and you can use the features for being with other students.

Account

• Email address and password, handled by Firebase Authentication (Google). We never see your password in plain text.

Profile and learning

• Your first and last name with a 4-digit tag (for example "Ana Petrovska#4821"), so students with the same name can be told apart.
• Your age group (under 14, 14–15, 16–17 or 18+). The app asks for your month and year of birth to work it out and keeps only the group, never the date. Your country (in the United States also your state, because each state has its own school standards), school year, subjects, daily goal, difficulty, avatar and items, and whether you are a student or a teacher.
• If you choose it, your school (from TONEC STUDY's list of schools).
• Your learning progress: answers, results, streaks, XP, IQ (the in-app currency, previously called tokens), badges and grades.

Being with other students

• Who sees your name: once friends are switched on for you (see section 7), other students in your age band can find you by name and see your name, avatar, level and school year. Minors and adults can never find, add, message or call each other. Until then, nobody can find you by name.
• Friend requests, friendships and blocks.
• Messages with friends, stored so both of you can read the conversation. Messages can't contain links, email addresses or phone numbers, and swear words are replaced by asterisks automatically.
• Calls and classrooms: who called whom and when, and who joined a classroom, duel or race, with the scores. Voice and video go live through LiveKit and are never recorded.
• Notifications (Android): if you allow them, your phone's notification token, used only to tell you about your friends' messages and calls. A notification shows the friend's name and the message.
• Reports: if you report someone, who reported whom, the reason and the context.

Teachers

• If you ask to be verified as a teacher: your name, account email, school, city, country, school website, work email, what you teach and any message you add. We use it only to check that you are a teacher and email you the decision.

Photos of book pages (Premium "Learn from your book")

• The photos you take of your book pages are shrunk on your phone and sent through our server to Anthropic's Claude AI, which writes practice questions from them. TONEC STUDY does not store the photos, and under Anthropic's commercial terms they are not used to train AI models. The app tells you that the questions are written by AI.
• The quiz made from them (title, subject, questions and answers, with the app language, school year and country) is saved in your account until you remove it. We also use these questions, without your name or account, to improve TONEC STUDY's questions for your country and grade.
• We count how many scans you used (for the limits) and how much AI processing they needed (for costs). If you report an AI question, we store the question, the reason and your account ID.
• Please don't photograph pages with personal details on them. The AI is told never to copy such details.

Parent confirmation (children under 14)

• The child enters a parent's or guardian's email address. We store it with the app language, a one-time code and whether and when the parent confirmed or withdrew. We send one email asking the parent to confirm, and once they do, a second email with a link to withdraw the consent at any time.

Weekly report for parents (Premium, grades 1–9)

• The parent's email address you enter. Nothing is sent until the parent confirms it, and every report has a link to stop them.
• A short summary saved in your account: your first name, school year, how many questions you answered per subject last week, how many were right the first time, and your grades. It is emailed every Sunday evening to the confirmed parent only.

School leagues

• Which school you picked and how many points you earned for it each day, week, month and year. Other schools see only school names, towns and totals. Your school's own ranking also shows its students with their avatar, first name and the initial of their last name – only to students of the same school, never between students under 18 and adults, and only for students who are allowed to have friends (anyone else is shown as “A student”). A school you add is shown to others only after we check its name.

Purchases

• IQ, items, TONEC STUDY Premium and the Matura practice pack are sold through Google Play (or the Apple App Store); TONEC STUDY never sees your payment card. RevenueCat confirms purchases and links Premium to your TONEC STUDY account ID.

Optional ads

• After a game you may choose to watch a short ad to double the IQ that game earned. Ads appear only when you tap that button; Premium members get double IQ without ads.
• The ads come from Google AdMob. TONEC STUDY asks only for non-personalized ads rated G, and the app does not use or send the phone's advertising ID. Requests from accounts under 14 are marked as directed to a child, and from accounts under 16 as under the age of consent.
• To show an ad, AdMob receives technical information such as the phone model, system, app version and IP address (see Google's advertising policies). We never send it your name, email, answers or messages.

Technical information

• Question text may be sent to Google Cloud Translation to show it in your language; it is not linked to you.
• Error reports: if the app runs into an error, it sends the error message, where it happened, the app version and the phone model and system, with your account ID if you are signed in. No messages or answers.

The TONEC STUDY app has no analytics, tracking or third-party crash-reporting tools. We do not sell personal data, we do not show personalized ads, and we do not build profiles of you for advertising.

3. Why we use it, and on what legal basis

TONEC STUDY makes no decisions about you based only on automated processing that have legal or similarly significant effects. The automatic message filter only hides words and blocks contact details.

4. How long we keep it

5. Who we share it with

Only with the service providers that make TONEC STUDY work. They process data for us under their data processing terms:

• Google (Ireland / USA): Firebase Authentication, Firestore database, Cloud Functions, Cloud Messaging and Hosting; Cloud Translation; AdMob; Gmail, for TONEC STUDY's emails; Google Analytics, for this website only and only with your consent.
• RevenueCat (USA): purchase confirmations and Premium.
• LiveKit (USA): live voice and video for calls and classrooms.
• Anthropic (USA): writes the questions from book photos. It receives the photos, the app language and the school year, not your name or email.
• Hostinger (EU): the support@tonecstudy.com mailbox, where emails you send us are kept.

Google Play sells the purchases under its own terms and privacy policy. Other students see only what section 2 describes. We may disclose information if the law requires it, or to protect a child in danger.

6. Where the data is

TONEC STUDY's database is in Google Cloud's European region. Some processing takes place in the USA (Cloud Functions, RevenueCat, LiveKit, Anthropic). Transfers from North Macedonia to EU/EEA and NATO member states, the USA included, are allowed under the Law on Personal Data Protection. For users in the EU, EEA, UK and Switzerland, transfers to the USA rely on the EU–US Data Privacy Framework where the provider is certified, or on the European Commission's Standard Contractual Clauses in the providers' data processing terms.

7. Children

TONEC STUDY is made for students, many of them children. We collect only what an activity needs, and we:

• Ask every user's month and year of birth, keep only the age group it gives, and keep minors and adults apart in search, friends, messages, calls and open classrooms.
• Under 14 (the age of digital consent in North Macedonia): purchases, the school league and everything to do with other students stay off until a parent or guardian confirms by email. Until then, nobody can find the child by name. In the United States, friends, messages, calls and classrooms stay off for children under 14 even with a parent's confirmation.
• 14–15: a parent's OK on the phone before friends, messages, calls and classrooms.
• Show children only optional, non-personalized ads marked as directed to a child, and never use the advertising ID.

Parents and guardians can at any time ask us to show them the information we keep about their child, to correct or delete it, or to stop collecting it, by writing to support@tonecstudy.com. The link in the confirmation emails withdraws the consent in one tap. If you believe we collected a child's information without the needed consent, tell us and we will delete it.

Children in the United States (COPPA)

For children under 13 in the United States, this section is our notice under the Children's Online Privacy Protection Act (COPPA) and the FTC's COPPA Rule.

• What we collect from a child under 13 is listed in section 2: the account, name, age group, country and state, school year, subjects, school if chosen, and learning progress. We collect it only to run TONEC STUDY for the child, and no more than an activity needs. Until a parent confirms, a child uses the app without an account: the profile and progress stay on the phone, and only the technical requests in section 2 (the ads, error reports, translations and question downloads) leave it, without the child's name.
• Parental consent. Before a child under 13 can have an account, buy anything, join the school league or get the weekly report, a parent or guardian confirms by email (section 2). Friends, messages, calls and classrooms stay off for US children under 14 even after a parent confirms, so a child's information is never made public or shared with other users.
• No advertising use. We do not disclose a child's personal information to anyone for targeted or behavioral advertising, we do not sell it, and we do not build profiles of children. Ads are optional, non-personalized and marked as directed to a child (section 2); the technical information AdMob receives to show one is used only to deliver and measure that ad. Because we never use a child's information for advertising, we do not ask parents for that kind of consent.
• Who receives it. Only the service providers in section 5, which process it for us to run the app. Each is chosen and bound to protect it; none may use it for its own purposes.
• How long we keep it. Section 4 is our data retention policy: a child's information is kept only as long as the child uses TONEC STUDY, and is deleted when the account is deleted, when a parent asks, or after 2 years without use.
• Security. We keep a written information security program for the measures in section 9.
• Parents' rights. A parent may review the information we have about their child, have it deleted, and refuse any further collection or use, by writing to support@tonecstudy.com or using the withdrawal link in our emails. We first check that the request comes from the child's parent.
• Schools. TONEC STUDY is offered to students and families. It is not provided to US schools or districts under contract, and we do not receive student records from schools. A school that wants to use it with its students should contact us first.

US state privacy laws

We do not sell personal information or share it for cross-context behavioral advertising, as those terms are used in California and other US state privacy laws, and we do not use students' information for targeted advertising or to build profiles. Residents of any US state can ask us what personal information we hold about them, and ask us to correct or delete it, at support@tonecstudy.com; we do not treat anyone differently for asking.

8. Your rights

• You can see and change your profile in the app, and delete your account in Settings → Account or as described on this page.
• You also have the right to get a copy of your data (also in a reusable format), to have it corrected or deleted, to restrict or object to its use, and to withdraw a consent you gave (this does not affect what was done before). Write to support@tonecstudy.com; we answer within one month. We may ask you to confirm the request from your account's email address.
• You can complain to the Agency for Personal Data Protection of North Macedonia (Агенција за заштита на личните податоци, azlp.mk, info@privacy.mk), or to the data protection authority of the country where you live.

9. Security

Data travels encrypted (HTTPS) and is stored with Google, encrypted at rest. Security rules limit each account to its own data and to the people it has connected with; only the developer can manage the database. Passwords are kept by Firebase Authentication and card details only by the stores. If a breach ever puts your data at risk, we will inform the Agency for Personal Data Protection within 72 hours and tell you if the risk to you is high.

10. This website

This website has no ads. When you first visit, it asks whether you accept analytics cookies:

• If you accept: the site loads Google Analytics (Google Ireland Limited / Google LLC) to count visits and see which pages are read. Google sets its cookies (_ga, _ga_*, kept up to 2 years) and receives the pages you open, the site that sent you, your browser, device type and language, and your approximate location (country and city) worked out from your IP address, which Google Analytics does not store. Google signals and advertising features are switched off. The statistics are kept for 14 months. The legal basis is your consent.
• If you decline, or don't choose: no analytics code loads and no cookies are set.
• You can change your choice at any time with Cookie settings at the bottom of every page. Withdrawing consent stops the analytics from then on and removes the cookies.

Apart from that, the site saves in your own browser only your cookie choice and whether you closed its language suggestion. Google Firebase Hosting delivers the site and processes technical request data such as IP addresses to do so.

11. Changes

If we change this policy in an important way, we will update the date above and tell you in the app.
