Privacy Policy

Last updated: April 2026

Short version

Sumami keeps all your data (match history, settings, player names) locally on your device — we never see any of it. The app sends only anonymous stats: how often it’s opened and from which country. We do this so we know whether the game is actually being used and where in the world. The website you’re reading now works the same way.

What we store on your device

All this data lives in a local Hive database on your phone. Uninstall the app to remove it. We never see it.

What we do NOT collect

Third parties

Google Analytics (Firebase) — anonymous usage stats. We count app opens, country and device type. No advertising identifiers, no profiles, no cross-app tracking. Your scores, player names and match history never leave your phone — those we don’t send anywhere.

Website

sumami.sisters.plus uses Firebase Analytics (Google Analytics 4) in cookieless mode: we count visits, countries and device types, anonymize IPs, set no tracking cookies and build no advertising profiles. Plain stats, so we know how many people find Sumami and where from.

Children

Sumami is rated 4+. Since we collect nothing, the app is safe for children to use without any parental consent flow — there is nothing to consent to.
