Trivocab

Privacy Policy

Effective and last updated: September 23, 2026

This policy explains how personal data is handled when you use the Trivocab mobile app (the “App”).

In short: You don’t need an account. We never ask for your name, email, phone number or location. Your learning progress stays encrypted on your device. The App shows no ads and we never sell your data. To fix bugs and improve the App we use Unity’s analytics and crash reporting service only if you allow it. We ask on first launch, and you can change your choice any time in Settings › Share usage data.

1. Who is responsible

Burak Avar (developer of the App)
Contact: b2avargames@gmail.com

2. What we process, why, and on what basis

Data	Where it is stored	Purpose	Legal basis
Learning progress (completed lessons, stars, badges, streak, saved and weak words) and app settings	Only on your device, in an encrypted and signed file. Never sent to us.	Running the App and letting you continue where you left off	Necessary to provide the service
Encrypted copy of your progress (iPhone/iPad only)	Your own iCloud account (Apple). We cannot access it.	Syncing progress between your devices signed in with the same Apple ID	Necessary to provide the service
Usage data: completed lessons and reviews, score, number of mistakes, badges claimed, level test result, session start/end	Unity Technologies servers	Understanding how the App is used and improving lessons and difficulty	Consent, asked on first launch; not collected if you decline, can be withdrawn in Settings
Technical data and crash reports: IP address and the approximate location derived from it (country/city level), a random installation ID, the iOS identifier for vendor (IDFV), device model, OS and language, app version, crash and error logs	Unity Technologies servers	Detecting and fixing crashes and errors, keeping the service secure	Consent (the same permission as above)

This data is not linked to your name, email or any other identity, is not used for advertising or cross-app tracking, and is never sold.

Features that stay on your device

Pronunciation: English words are read aloud by your device’s own speech engine, offline.
Daily reminder: Notifications are scheduled on your device; no server is involved. You can turn them off in your device settings or with the Daily reminder switch in the App.
Android backup: On Android, the progress file may be part of your phone’s automatic backup to your Google account. Google manages this backup; we cannot access it.
Support email: Settings › Contact us opens your email app with the app version, device model, OS and language added below your message. It reaches us only if you send it; your email address and these details are used only to reply to you.

3. Sharing and international transfers

Usage and technical data are shared with our service provider Unity Technologies (Unity Gaming Services – Analytics and Diagnostics), whose servers are located outside Türkiye and may be outside your country. Unity’s terms: Unity Game Player and App User Privacy Policy. We may disclose data to public authorities where required by law. We do not share it with anyone else.

4. How long we keep it

Progress on your device: until you delete it (Settings › Reset progress, or uninstalling the App).
Usage and technical data: up to 13 months at Unity, after which it is deleted or anonymised.

5. Security

The progress file is encrypted with AES-256 and signed. Its key is not part of the App: it is generated for each installation and stored in the iOS Keychain or in Android’s app-private storage. Communication with Unity uses encrypted connections (HTTPS).

6. Consent, turning off and deleting usage data

When the App is first opened it asks for your permission for usage data and crash reports. If you decline, none of this data is sent and every feature of the App still works. When you switch off Settings › Share usage data, new data stops being sent and a request to delete the usage data already sent to Unity is submitted automatically. You can also email us to request deletion.

7. Your rights

Depending on where you live (including under Türkiye’s KVKK and the EU/UK GDPR), you may have the right to access, correct, delete or restrict the processing of your personal data, to object to processing, and to lodge a complaint with your data protection authority. Contact us at b2avargames@gmail.com; we will reply within 30 days, free of charge.

8. Children

The App is not directed to children under 13 and does not knowingly collect personal data from them.

9. Changes

We may update this policy. The current version is always published on this page, and significant changes will also be announced in the App.
