Privacy Policy
Sumo Arena 3D – last updated November 7, 2026
This policy explains what data the game Sumo Arena 3D ("the game") by Ramzi Mammadli ("we", "the developer") collects, why, and how you can have it deleted.
Summary
- No banners or forced ads: the only ads are optional rewarded videos that you choose to watch (Unity Ads). No third-party analytics.
- We do not collect your name, e-mail, phone number, location, contacts, photos or any payment information.
- We store only what is needed to run the game: an anonymous player ID, your in-game name, game progress and leaderboard results.
Services we use
The game uses Unity Gaming Services (provided by Unity Technologies) to run its online features: Authentication, Cloud Save, Leaderboards, Lobby and Relay. Unity processes the data below on our behalf only to provide these features. See Unity's privacy policy at unity.com/legal/privacy-policy. In-App Purchases are processed by Apple or Google Play. Optional rewarded videos are provided by Unity Ads, which may process device identifiers (such as the advertising ID) and ad interaction data to deliver and measure ads; see Unity's privacy policy.
Data we collect
- Player ID – an anonymous ID created by Unity Authentication when you first play. It identifies your saved progress and your leaderboard entries.
- In-game name – the nickname you choose (a random one is given at first), shown to other players and on leaderboards.
- Gameplay content – your game progress (level, coins, gems, owned and equipped items, missions) is stored on your device and backed up to Cloud Save. Tournament wins (crowns) are submitted to the public leaderboards together with your in-game name, level and equipped skin only if you allow it: the game asks before anything is uploaded, and you can turn it off at any time in Settings → “Show me on leaderboards”.
- Purchase history – purchases are processed entirely by Apple or Google Play. We never receive your payment details; the game only records the transaction ID so that a purchase is credited exactly once.
- Online sessions – when you play online, Lobby and Relay temporarily process connection data (such as your player ID and IP address) to connect you with other players. Your phone and the room owner's phone exchange game data (positions, your in-game name and equipped items) for the duration of the match only.
How we use data
Data is used only to provide the game's functionality: saving progress, leaderboards, online multiplayer and delivering purchases. Apart from the optional rewarded videos it is not used for advertising; it is not sold and not shared with data brokers. It is not used to track you across other apps or websites.
Retention and deletion
Game data is kept while you play the game. Deleting the app removes all data stored on your device. To delete your cloud save and leaderboard entries, contact us via the support page or ravanzakaryali@gmail.com with your in-game name; we delete it within 30 days.
Children
The game contains no forced ads and no free text chat (only preset emotes). We do not knowingly collect personal information from children beyond the game data described above.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
