Imposter: Find the Liar — the social deduction party game
Last updated: 12 October 2026 (version 2.0.1)
A game on one phone sends us nothing. Your players, scores and settings stay on your device. Online rooms are different: to play with people on other phones, the name you pick and the clues you type are kept on our server for about a day, so the others in your room can see them. The app has no ads, no analytics and no crash reporting.
This is stored on your device and is never sent to us:
A round in progress is never written to disk at all. Uninstalling the app deletes everything above.
Online rooms need a server, because nobody's phone may hold another player's card. When you make or join a room, this happens:
Who can see it. Everyone in your room sees your name, icon, clues and score. Only your own phone can read your card and your vote. The result shows who the room accused, not who voted for whom. A room can be joined only by someone who has its four-letter code.
There is no chat, voice or video. The only things a player can type are a name and one-word clues.
How long it is kept. A room expires a day after the last thing that happened in it. The room, its players, cards, clues and votes are then deleted automatically. Deletion is not instant, and normally completes within two days of that last activity.
What is kept longer. Two things, neither of which names you: the random ID itself, and a count of how many rooms that ID has made. The count is how the app knows whether your one free room has been used. A table you played online is also saved on your own device, in your history, like a one-phone table.
Where it is. Rooms are stored in Google Cloud Firestore and handled by Google Cloud Functions, in Mumbai, India. When your phone talks to these services, Google receives technical data such as your IP address, as any internet service does. Firebase Authentication keeps the IP addresses it logs for a few weeks. See Privacy and Security in Firebase.
Checking it is the real app. From version 2.0.1, when you play online the app uses Firebase App Check, a Google service. Your phone asks Google Play (Play Integrity) or Apple (App Attest) to confirm that the app is a real copy on a real device, and sends the answer to Google with each request. This is used only to keep scripts and fake apps out of rooms. It does not say who you are.
The app sells two things: Imposter Pro, a one-time purchase that opens every word pack, and Imposter Online, a monthly or yearly subscription for the person who makes online rooms. Joining a room is free.
The App Store and Google Play process the payment. We never see or handle your card or billing details.
RevenueCat keeps track of what has been bought, so a purchase can be restored on a new device. It receives an anonymous app-user identifier and the purchase receipt from the store. Once you have used an online room, that identifier is the same random ID described above, so that our server can check that a host's subscription is running. RevenueCat does not receive your name, your clues or your payment details from us. See RevenueCat's Privacy Policy.
The app checks Expo's update service for small fixes when it starts. That request carries the app version and your device's platform, and Expo's servers see your IP address when they answer it. See Expo's Privacy Policy.
We do not sell, share or rent personal information. The only companies that handle data for this app are the ones named above: Google (Firebase), RevenueCat, Expo, and the store you bought from. Each acts on our behalf or as the store of record.
Online rooms delete themselves, as described above. Uninstalling the app removes everything on your device, including the random ID.
To have a room, or the room count kept against your random ID, deleted sooner, write to the address below. We do not know who you are, so tell us the room code and roughly when you played, and we will delete it. The steps are on the data deletion page.
The app does not require sign-up, login or any account creation. One-phone games work immediately and offline. Online rooms sign in anonymously on their own.
The app is a word game played in a group. One optional word pack, "After Dark", contains adult themes, is not among the free packs, and asks before it is added. Online rooms let players type a name and one-word clues to the other people in the room. The app is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.
We may update this policy from time to time. The date at the top changes when we do. The latest version is always available in the app under Settings > Privacy Policy.
