Privacy policy

Last updated: 5 November 2026

In short

You do not need an email address, phone number or real name to play Bounce Swish. You play as a guest under a nickname you choose. The game shows Google AdMob ads; to improve the game we collect usage statistics and crash reports with Google Firebase. There is no location permission. We do not sell your data.

Data we keep

  • Nickname and the player number the game gives you.
  • Game progress: completed levels, stars, best shot count and time; energy and the shots of a level.
  • Wallet: coin balance, daily reward streak, and the looks you bought and use.
  • Time offset: your device's UTC offset, to decide the day of the daily reward.
  • Room matches: the room code, the nicknames of the players who joined and the match results.

When connecting, technical details such as the device model, operating system, language and time zone are sent; they are not stored in your game account. Our server may keep connection logs such as IP addresses for a short time to run and secure the service.

Ads

The game shows Google AdMob ads: an interstitial when a room match ends and every few levels in solo play, and, if you choose to watch one, a rewarded ad for energy, your daily streak or coins. Google processes your device's advertising ID, IP address and device information to show and measure ads and to prevent abuse. For a rewarded ad, your player number and a one-time reward key go to Google and from Google to our server so the reward can be verified.

In the European Economic Area, the UK and Switzerland, Google's consent form opens before any ad; you can change your choice at any time in Settings → Privacy options. You can reset or delete the advertising ID in your device settings. How Google uses data: policies.google.com/technologies/partner-sites.

Usage statistics and crash reports

Google Firebase Analytics shows us how the game is played: levels started and finished, shot counts, running out of energy, ad results, the daily reward, shop purchases and room matches. Along with these, the app instance ID, advertising ID, device model, operating system, language and a country-level location derived from the IP address are processed. Firebase Crashlytics sends a record of the error and device details if the game crashes. We use this data only to fix and improve the game; your nickname and player number are not sent with it. In the European Economic Area, the UK and Switzerland, your ad consent choice applies to Firebase too. How Google uses data: firebase.google.com/support/privacy.

Kept on your device

Your session key and game settings are stored encrypted on your device. Uninstalling the app removes them from the device.

Where it is stored

The game server and the database run on a server we rent in the European Union (Germany). Database backups are kept in Cloudflare's storage service (R2) for 30 days and then deleted automatically. Firebase data is kept on Google's servers. Your data is used only to run the game: saving your progress, working out rewards and energy, and running room matches.

Deletion and contact

Changes

If another service is added to the game or the data moves elsewhere, we will update this page and its date.
