TestYech — preparation for the National Certificate exam.
Last updated: 28 October 2026
This app exists to help a student prepare for an exam. It therefore stores only what that preparation requires and collects nothing else.
What the app does NOT collect
- Email address — Sign in with Apple does not request it either
- Phone number
- Location
- Contacts, photos, calendar or any other files on your device
- Advertising identifier
- Tracking across other apps or websites
- Payment card details — purchases are handled by Apple
- Crash reports
The app contains no advertising. Data is never sold or shared with third parties. The app does not track you across other apps or websites.
What the app stores
| Anonymous identifier | Created automatically the first time the app opens. It is not tied to your name; it exists so your progress can be attached to your device. |
|---|---|
| Study progress | Completed topics, points (XP), daily streak, practice days and mock-exam results. |
| Name — only if you link an account | If you sign in with an Apple ID and choose to share your name, that name. If you connect Telegram, your Telegram name and Telegram identifier. |
| Profile — all optional | Saved only if you enter them yourself: last name, username, school grade, year of birth, province and your chosen avatar character. None of these are required — each can be left blank or cleared later (Profile → Edit). The province comes from a list you pick from; the app does not read your device location. |
| How the app is used | Short in-app events such as "topic finished", "mock exam finished, score 42%", "TestYech Pro screen shown" or "subscription purchased". They are stored in your own record, under its identifier, and we use them only to see which parts of the app help students and which do not. No name, answer text or message is part of an event. They are deleted with your account. |
| Feedback you send | If you write to us from Profile → Feedback, the text you typed, stored in your own record so we can read it. |
| TestYech Pro subscription | Purchases go through Apple; we never see your card. To know whether TestYech Pro is active, the app uses RevenueCat, which receives your app identifier and the App Store transaction. Manage or cancel the subscription in your Apple ID settings. |
The first topic of every subject works without an account. An account is needed for the full question bank, XP, the daily streak and the mock exams. You can delete it at any time in Profile → Delete account — one step, immediate, including the cloud record.
Where the data is stored
Data is stored in Google Firebase (Authentication and Cloud Firestore). Server rules are configured so that each user can read and modify only their own record; there is no way to reach anyone else's data.
Notifications
Reminders are computed and scheduled entirely on your device. The app sends nothing to any server for them. You can turn notifications off at any time, either in the app's settings or in iOS settings.
Deleting your data
- Delete your account entirely: Profile → Delete account. Your account, your cloud record and everything stored on the device are erased immediately. This cannot be undone.
- Sign out but keep your data: Profile → Sign out.
- Delete the app from your phone — everything stored on the device goes with it.
- Questions or help: @testyech_support_bot.
Children
The app is made for school students, and some users may be under 13. None of the profile fields listed above are required: the first topic of every subject works without an account, and the profile can be left empty entirely.
If your child has entered information and you want it removed, everything can be erased immediately from inside the app via Profile → Delete account, or write to @testyech_support_bot.
Changes
If this policy changes, the date on this page is updated. If the scope of collected data ever widens, that will also be announced inside the app.
