TYT Konu & Soru: Öğren Privacy Policy
Last Updated: October 11, 2026

This Privacy Policy explains which data the Android and iOS application TYT Konu & Soru: Öğren ("App") processes, for what purpose and how. The App is a study app offering lessons, a question bank and mock exams for high school students and graduates preparing for the Basic Proficiency Test (TYT) of Türkiye's university entrance exam (YKS).

Developer / Data Controller:
Abdulkadir ER
Contact: akeproject.0@gmail.com

For details on processing under the Turkish Personal Data Protection Law (KVKK), see the KVKK Information Notice.

1. Summary

• You do not need to create an account or sign in. An anonymous account is created automatically on first launch.
• The questions you solve, your progress, mistakes, favorites and mock exam results are stored only on your device and are not sent to our servers.
• There are no ads, no advertising identifier (Advertising ID / IDFA) is used, users are not tracked, and your data is never sold.
• The App does not request location, camera, microphone, contacts or photo access.
• There is no messaging, chat or public profile between users.
• Payments are handled by Google Play and the App Store; your card details never reach us.

2. Children's and Teens' Privacy

The App is intended for high school students and graduates preparing for the TYT (typically aged 15 and over). It is not designed for children under 13, and we do not knowingly collect personal data from anyone we know to be under 13. We recommend that users under 18 use the App with the knowledge of a parent or guardian.

To protect this age group:
• The App can be used without an account; information such as name and email is processed only if you choose to sign in.
• There are no ads, no advertising identifier and no personalized advertising; data is not used for marketing or profiling.
• There is no feature that lets users contact each other.
• Purchases go through the store; parents can approve purchases with Google Family Link or Apple "Ask to Buy".

Parents or guardians can request information about, or deletion of, their child's data at akeproject.0@gmail.com; requests are completed within 30 days.

3. Data Stored Only on Your Device

• Solved questions, per-topic correct/incorrect statistics and study time
• Mistakes and favorite question lists
• Mock exam results
• Lesson progress
• Points (XP) and level (also written to your profile, see below)
• Birth year, gender and city, if you choose to enter them in the App
• Downloaded question, exam and lesson packs
• Theme, sound, vibration, reminder and similar preferences

These are deleted when you uninstall the App or clear its data. If Android device backup is enabled, the operating system may include them in your Google account backup; we have no access to that backup.

4. Data Processed on Our Servers

A. Account (Firebase Authentication)
• Anonymous account: a random user ID (uid) is created on first launch. It does not identify you personally.
• Optional sign-in: if you want to move your data to another device, you can sign in with Google, Apple or email/password. Depending on the method, your email address, name, profile photo link (Google) and the related account ID are processed. Apple may hide your email address. With email/password sign-in your password is stored by Firebase Authentication; we cannot see it.
• Your account is shared across the same developer's KPSS, TYT and LGS study apps: with the same sign-in method you use the same account in these apps.

B. Profile (Cloud Firestore)
Your profile document holds: the selected exam, daily study goal, the nickname you enter, avatar and avatar color, points (XP) and level, account creation and last sign-in times. Only you (and the system during account deletion) can read or write it; it is not shown to other users.

C. Question of the day
When you answer the question of the day, the option you chose is saved on our server together with the date and your user ID (uid). This is used so that you can answer only once per day and to show you your own answer. Other users see only the total number of correct and wrong answers, never who answered what.

D. Question reports
When you report a question with the "Report" button, we receive: your user ID (uid), question/topic ID, question text and options, the correct answer, the selected reason, your optional note (up to 1000 characters), the content pack version and the date. This is used only to fix content. Please do not write personal information in the note.

E. Subscription
When you buy Premium, payment is taken by Google Play or the App Store. The App sends the product ID and the purchase token to our server, which verifies it with the store. We store your user ID, product, expiry date and whether the subscription is active. Card or payment details never reach us.

F. Usage statistics (Firebase Analytics)
Automatically collected events are processed to understand overall usage: first open, session start, engagement time, screen views, app and OS updates, together with the app instance ID, device model, operating system, language and approximate location (country/city) derived from the IP address. Analytics data is not linked to your account (no user ID is sent) and is not used for advertising.

G. Crash reports (Firebase Crashlytics)
If the App crashes or an error occurs, the error log, device model, OS version, Crashlytics installation ID and your user ID (uid) may be sent to Firebase Crashlytics so we can fix the problem. The user ID is added only to tell whether an error repeats and to help you if you contact us; your name or email is not sent.

H. Notifications (Firebase Cloud Messaging and local reminders)
The App asks for notification permission. If granted, Firebase creates a push token for your device; we do not store this token in our database. Study reminders are scheduled locally on your device. You can turn notifications off in device settings at any time.

I. App integrity (Firebase App Check)
To protect our backend from abuse, Google Play Integrity (Android) and Apple App Attest / DeviceCheck (iOS) verify that the app and device are genuine. No data identifying you is stored.

J. Content downloads (Firebase Storage and Cloud Firestore)
Question, exam and lesson packs and announcements are downloaded from our servers. Nothing is uploaded from your device.

5. Purposes

• Providing the core features (practice, mock exams, lessons, question of the day)
• Moving your profile between devices when you sign in
• Verifying Premium subscriptions and unlocking content
• Fixing reported questions
• Improving stability and performance
• Preventing abuse and fraud
• Complying with legal obligations

Your data is not used for advertising, profiling or marketing and is not sold.

6. Storage Location and International Transfers

Data is stored on Google's Firebase infrastructure. Our Cloud Firestore database is located in Europe (Frankfurt, europe-west3) and content packs in the United States (us-east1). Analytics, Crashlytics, Authentication and Cloud Messaging data is processed on Google's global infrastructure. Your data is therefore transferred abroad; see Third-Party Services.

7. Retention

• On-device data: until you uninstall the App or clear its data
• Account and profile: until you delete your account
• Question of the day answers: until you delete your account; deleted with the account
• Question reports: kept for content quality; your user ID is removed when you delete your account
• Subscription record: kept even after account deletion so the store subscription can continue and be restored with a new account; legal retention duties apply
• Analytics and Crashlytics: according to Google's retention periods

8. Deleting Your Account and Data

Delete your account in the App under Settings → Account → Delete account. If you cannot access the App, email akeproject.0@gmail.com. What is deleted and what is kept is described on the Account and Data Deletion page. Deleting your account does not cancel your store subscription.

9. Security

All communication with our servers is encrypted (HTTPS/TLS). Database security rules ensure that each user can access only their own data. No system is completely risk-free; in the event of a breach we will notify as required by law.

10. Your Rights

Under the Turkish Personal Data Protection Law (KVKK) and the GDPR you have the right to access, rectify or erase your data, to object to processing and to data portability. A parent or guardian may exercise these rights on behalf of a user under 18. Send requests to akeproject.0@gmail.com; we respond within 30 days.

11. Changes

We may update this policy as the App changes. The current version is always published on this page with an updated date.
