Privacy Policy
This page explains plainly what information goes where when you use Tercümen. In short: your camera image never leaves your phone, and there are no ads or tracking.
Last updated: 15.09.2026
01Who we are
The Tercümen mobile app and the tercumenceviri.com website are provided by KODDÜNYASI. KODDÜNYASI is the data controller under the Turkish Personal Data Protection Law No. 6698 (KVKK).
For any privacy question or request: destek@tercumenceviri.com
02Account and sign-in
- You sign in to the app only with a Google or Apple account. Sign-in is handled by Google Firebase Authentication. We never ask for or store a password.
- During sign-in, the provider you choose shares your account identifier, email address and display name. If you choose to hide your email with Sign in with Apple, only Apple’s relay address is shared.
- This information is kept in the Firebase Authentication account record. Only the account identifier is sent to our own servers in connection with your account.
- We use it to link your subscription to your account (so it follows you to a new phone) and to prevent translation votes and error reports from being counted multiple times for the same person.
03What we never collect
- Location
- Advertising identifiers, advertising or third-party tracking data
- Contacts
- Photo library
- Phone number
- Passwords
The app contains no advertising SDK and no analytics or crash-reporting service.
04What stays on your device
The following is processed only on your phone and is never uploaded or stored:
- Camera image. Subtitle text is read on the phone; the image itself goes nowhere.
- Microphone audio. Speaker detection and speech-to-text run on the device. Nothing is recorded or sent.
- Screen-stream frames. Video from a computer or console is processed on the phone.
- Pairing data. Computer and console pairing keys and PlayStation Network session data stay on the phone.
- Latency and performance measurements.
05What reaches our servers
- For supported games: the English subtitle text read from the screen and its Turkish translation. These go into a shared translation pool that belongs to the game and is not linked to any person.
- For games not in our list: only the game title and the number of lines. No subtitle text is sent.
- Your account identifier, or a randomly generated device identifier if you have not signed in yet.
- Your RevenueCat user identifier, to verify your subscription.
- What you choose to send: translation error reports and translation votes.
