Privacy Policy

Last updated: October 15, 2026

Sahtekar is a party game played together in the same place, with everyone on their own phone. The game is available in Turkish and English. This policy explains what data the app processes and why. In short: no accounts, no ads, no tracking, no selling of personal data.

Data controller

Data controller: HK Lab (Haki Çakmak) (“we”). We provide the Sahtekar app and related services. This text serves as the notice required under Article 10 of Turkey’s Personal Data Protection Law No. 6698 (KVKK).

Data we process

• Device ID: when the app first opens, it creates a random ID on your device. It is used only to tell you apart from other players in a game room and to let you rejoin the room if your connection drops. It is not linked to your name, email, phone number or advertising ID.
• Player name: the name you enter to show in the game is stored on your device and shown to the players in the room you join. While the room is open it is processed on our server to run the game; to prevent abuse, administrators can see player names in open rooms (they cannot see game information such as the words you write or roles). It is deleted from the server when the room closes.
• In-game content: the one-word clues you write, your votes and your reactions are shown only to the players in the room. They are deleted when the room closes; no game history is kept.
• Reports: if you report a player, the reason, that player’s name and their recent entries are reviewed to prevent abuse; they are deleted no later than 180 days after a decision.
• Anonymous usage data: to improve the app, the following is sent with a random installation ID: platform, operating system and app version, device model on Android, language, country (a two-letter code from your device’s region setting, not your location; the IP address is not stored), session length, screens opened, how many players a game had and how long it lasted, the chosen word pack and the result, app errors, and performance measurements (app launch time, smoothness of the game display, server connection speed and number of disconnects). Your name and the clues you write are not sent. Raw records are deleted after 90 days; daily totals that cannot be linked to anyone (e.g. how many games were played that day) are kept for up to 400 days to see trends. You can turn this off at any time in Settings → Anonymous usage data; turning it off deletes the installation ID.
• Feedback: if you send a suggestion or report a problem, your message is stored with the app version and device type. Email is optional, used only to reply to you, and deleted no later than 180 days after our reply.

We process this data to provide and improve the service and to prevent abuse, based on legitimate interest (KVKK Art. 5/2-f, GDPR Art. 6(1)(f)).

Data we do not collect

We do not collect location, contacts, photos, camera, microphone, health data, payment information or advertising IDs. The app has no ads and no third-party tracking tools; we do not track you across other apps and websites.

Device features

• Vibration and sound: for feedback at game moments. Sounds do not play while your phone is on silent; both can be turned off in Settings.
• Screen brightness: during voting, the selected player’s screen briefly lights up. Only the app window is affected; your system settings do not change.
• Keeping the screen on: so the screen does not go dark during a game.

Retention and security

Data is transmitted over an encrypted connection (TLS) and kept only as long as the service needs it: room data is deleted when the room closes, raw usage records after 90 days, and reports and feedback no later than 180 days. Your data is not sold to third parties or shared for advertising; only service providers working on our behalf and bound by the same rules, such as server hosting, can access it.

Children

Sahtekar is for ages 13 and up. We do not knowingly collect data from children under 13; if we become aware of such a case, we delete the data.

Your rights

Under KVKK Article 11 and the GDPR, you have the right to access, correct and delete your data and to object to its processing. You can delete the data on your device right away with Settings → Erase my data on this device; uninstalling the app also deletes all data on the device. For other requests, write to us; we reply within 30 days at the latest.

Changes

If we update this policy, we change its date; we announce important changes in the app.
