Data used by the app

The game itself is played entirely offline. The app does not create accounts, display advertising, or include usage analytics or tracking tools. It makes two network connections only: the App Store, described in the “In-app purchase” section, and crash reporting, described under “External services”.

The following information may be stored only in the app's private storage:

• entered player names and languages;
• photos chosen for players;
• favorite players;
• game, sound, and haptic preferences;
• the current game, its votes, and its leaderboard, so it can be resumed after iOS closes the app.

This information is used only to set up and play games. It is not automatically sent to Steve Diesbach or used for advertising.

The photo picker provided by iOS lets users choose an image without giving the app general access to the photo library.

The app excludes entered player names, photos, and games from automatic backups. iOS may nevertheless include certain technical preferences in a device backup managed by the user. Imposteur cannot access that backup and does not receive a copy of it.

Voluntary sharing

The “Share leaderboard” feature prepares text containing the leaderboard and the player names displayed in the game. This text is sent only if the user chooses a destination in the iOS share sheet. The chosen service then processes the content under its own privacy policy.

In-app purchase

After five free trial rounds, Imposteur offers a one-time purchase that unlocks the game permanently. The transaction is handled entirely by Apple through the App Store, under Apple's privacy policy. Imposteur receives no name, address, or payment details: the app only verifies, on the device, the receipt signed by Apple in order to unlock the game and restore the purchase. The number of trial rounds played is a simple counter kept in the app's private storage.

Retention and deletion

Local data remains in Imposteur's private container until it is deleted in the app's settings or the app is uninstalled. “Delete all data” also removes the checkpoint for the current game.

External services

Imposteur uses a single external service: Sentry, which receives crash reports. A game passed from hand to hand around a table will never be left to go and describe a bug; without these reports, a crash would stay invisible.

What is sent: the app version, the iOS version, the device model, and the place in the code where the crash happened. What is never sent: your identity, advertising or device identifiers, players' names and photos, the course of the game, or any image of the screen — screenshots and view hierarchy are explicitly disabled. The data is received on Sentry's European infrastructure, and nothing is sent from development builds.

The other network communication is Apple's StoreKit framework talking to the App Store: showing the price, processing the one-time purchase, and restoring a previous purchase. There is no other: the game itself is played offline.
