IMPOSTER by Sudarev · Developer and operator: Sudarev Daniil · Last updated: October 23, 2026

IMPOSTER ("the app") is a party word game. It has no accounts, no sign-up and no ads; optional in-app purchases are described in section 8. We do not collect your name, email, phone number, contacts or location, and we never sell or share data.

1. No account

The app works without registration or login. Player names you type are just labels for the game: they stay on your phone and, in a multiplayer room, are shown only to the other players in that room.

2. Data on your device

Your settings (language, sound, voice, vibration), player names, scores, custom word packs and a random game ID are stored only on your phone. Deleting the app deletes this data.

3. Multiplayer rooms

Wi‑Fi room: phones connect directly over your local network; nothing goes through our servers.

Online room: game messages (player names, cards, votes, the imposter's guess) are relayed through our server (Supabase Realtime). Every message is end-to-end encrypted between the host's phone and each player (X25519 + AES‑GCM) and sent over HTTPS/TLS. The server only passes messages along; it cannot read them and does not store them. The room disappears when the game ends.

4. AI features

Optional AI features — a word pack for your own theme, bots' clues, word explanations and checking the imposter's guess — send only the needed game text (the theme you typed, the secret word, other clues, the guess) and a random game ID to our server function (Supabase), which forwards the text to Anthropic's Claude model to get an answer. The random ID is used only to apply a daily usage limit. Generated word packs and explanations may be cached on our server without any link to you. Do not type personal information into the theme field. AI text is not used for advertising or to identify you.

5. No ads or tracking

The app has no advertising and no trackers. The only third-party services are listed in section 8. A single-phone game works fully offline.

6. Permissions

The camera is used only to scan the QR code of a room when you choose to join one; images are processed on the phone and are never saved or sent. Network access is used for rooms and AI features. The microphone, contacts, photos and location are not used. Vibration is used only as game feedback.

7. Children

The app is suitable for families and has a kids mode with simple words. It collects no personal data from anyone, including children. AI features process only game text, without personal data.

8. Services we use

Purchases. Payments are processed by the App Store or Google Play; we never see your card. To unlock what you bought and restore it on a new phone we use RevenueCat, which receives an anonymous app user ID and the purchase receipt — no name or email.

Notifications. If you allow them, we use OneSignal to send reminders and game news. It receives a random device token and your notification settings (language, on or off). You can turn notifications off at any time in the app or in the phone settings.

Error reports. If the game crashes or freezes, it sends a technical report through the Sentry service: game version, device model, system version and where in the code the error happened. Reports do not include your name, email, nickname or save data and are not used for advertising. You can turn this off in the game settings: “Send error reports” (or “Error reports”).

Anonymous statistics. The app can count launches with Plausible, a privacy-friendly analytics service that uses no cookies or advertising identifiers and does not store IP addresses. Nothing in these statistics identifies you.

None of these services uses your data for advertising or sells it.

9. Changes and contact

If this policy changes, the new version will be published on this page. Contact: [email protected].
