Duel Pong — Privacy Policy

Last updated: 12 November 2026 · App: Duel Pong: 1v1 Paddle (com.duelpong.eu)

Duel Pong is a real-time 1v1 paddle game. We keep the data we need to run online matches and nothing more. We never sell personal data.

What we store on our game server

• An anonymous game account, created automatically the first time you play online: a random ID and a secret key (we store only a hash of the key). No e-mail, phone number, real name or sign-in is required.
• Your profile and game data: the player name you choose, avatar, rating, wins/losses, coins, items you unlocked, missions, level, achievements, your last 20 matches and head-to-head records against other players.
• Match records (players, score, time) and error reports (the error message, app version and phone model) — used to keep matches fair and fix bugs. These logs are deleted after 90 days.
• Your IP address is used while you are connected (to run the match and to limit abuse such as mass account creation). We do not store it in your account.

Other players can see your player name, avatar, rating and your results against them.

On your phone

The app saves your settings, your account key and simple counters on your device. Uninstalling the app removes them.

Advertising

The Android app shows Google AdMob interstitial ads between matches. Google may collect and use device data such as the advertising ID, IP address and ad interactions to show and measure ads. In the EEA, UK and Switzerland the app asks for your consent first (Google's consent form). See how Google uses data from partner apps. You can reset or delete your advertising ID in your phone's settings.

Crash and error reports

To find and fix bugs, the app and our game server send crash and error reports to Sentry (Functional Software, Inc.), stored in Sentry's EU data region (Germany). A report contains technical data only: the error and stack trace, app version, recent technical log lines from the app, phone model, operating system version and a random installation ID. It is not linked to your game account and never contains your account key. Your IP address is used only to deliver the report and is not stored with it. Reports are kept for up to 90 days. See Sentry's privacy policy.

Where the data lives

Our game server is hosted by Hetzner Online GmbH in Germany (EU). Data is sent over the internet between your phone and the server only to play the game.

Deleting your data

In the app: Settings → Privacy & account → Delete my account (tap twice). This removes your account and all its game data from our server immediately; match and error logs that mention your account ID expire within 90 days. You can also ask us by e-mail — see account deletion.

Children

Duel Pong is not directed at children under 13, and we do not knowingly collect data from them.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions or requests: support@duelpong.com.
