When you use online features, our server stores:
| Data | Purpose |
|---|---|
| Nickname you enter | To show you on the leaderboard and to other players in multiplayer. Must be unique. |
| Random device identifier | A UUID generated on your device to associate your stats with your nickname. It is not your Apple ID, advertising ID, or hardware serial. |
| Device & locale info — device model, OS name/version, device name, language, locale, time zone, screen size, app version | To understand the range of devices the app runs on and to improve compatibility. |
| Country/region | Inferred from your device's locale setting (not GPS) to display alongside leaderboard entries. |
| IP address | Automatically seen and stored by the server when your device connects; used for basic abuse prevention and approximate region. |
| Gameplay counts — sessions, throws, hits | To compute statistics and the top-10 leaderboard. |
| Multiplayer chat messages | Free-text messages you send in a room — and the optional "dedicate your throw" toast — are shown to other players and stored on our server as recent room history, so someone joining mid-match can see the last several messages. Each message is saved with the nickname that sent it. Chat is automatically profanity-filtered. |
| Reports you submit | When you report a chat message, we store the reported message, the nicknames involved, and the room code, so we can review the report and act on it. |
Data is stored on a private server operated by the developer (hosted on DigitalOcean) in a local SQLite database, protected by a shared application token. We do not sell your data or share it with advertisers.
Kottabos depicts a historical drinking game for educational purposes and is not directed at children. It contains no real alcohol and no purchasing. Multiplayer rooms include a text chat so players can coordinate; we ask that you not share personal information there, and we may remove messages or nicknames to keep the service fair.
We may update this policy; the effective date above will change accordingly. Material changes will be noted in the app's release notes.
