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, no ads and no in-app purchases. 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, analytics or tracking

The app has no advertising, analytics, trackers, in-app purchases or third-party SDKs that collect data. 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. Changes and contact

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