Privacy policy
Last updated 2 October 2026. Applies to the Rubble Rumble website (rubblerumble.com) and the Rubble Rumble Android app.
The short version
- No accounts, no ads, no analytics or tracking, no in-app purchases.
- Practice against the computer runs entirely on your device. Nothing is sent anywhere.
- Online rooms send your chosen display name, your moves and any chat messages to our game server so the other players in your room can see them. A room's data is deleted when its last player leaves.
What we handle and why
| Data | Why | Where and how long |
|---|---|---|
| Display name you type | Shown to other players in your room | Saved on your device so you don't retype it. Held by the room server while you are in a room. |
| Sound on/off setting | Remembers your choice | On your device only |
| Game moves and field snapshots | Running the online match | Passed through the room server to the other players; the latest snapshot is kept in memory until the round ends |
| Chat messages | Room chat | Sent to everyone in the room. The room keeps its last 20 lines so newcomers can catch up, and deletes them when the room empties. |
| IP address and basic request data (time, URL, browser type) | Delivering the site, preventing abuse, fixing errors | Processed by our host, Cloudflare, and kept in short-lived operational logs |
Chat is filtered for offensive words and rate-limited, and you can mute any player in your room. We don't read, sell or share chat or names, and we don't use them for advertising.
Service providers
The game server and website run on Cloudflare Workers and Durable Objects. Cloudflare processes connection data on our behalf to deliver and protect the service. Fonts are bundled with the game, so no font service is contacted.
Children
Rubble Rumble is not directed at children under 13. Online rooms include chat with other players, so younger children should play Practice mode or play with an adult.
Your choices
- Play Practice mode to keep everything on your device.
- Use any name you like online. It doesn't have to be your real name.
- Clear the saved name and sound setting by clearing the site's data in your browser, or the app's storage in Android settings.
Changes and contact
If this policy changes, we'll update this page and the date above. Questions: privacy@rubblerumble.com.
