Effective date: September 17, 2026
Fuyomi (符読み) scores riichi mahjong hands on your device. There are no accounts, no ads, no analytics and no third-party SDKs. We never receive your hands, your practice history or your game records.
Nothing. The hands you enter, your practice answers, the games you keep score for (including the player names you type), your name if you enter one in Settings, your rule settings and your onboarding choices stay in the app's storage on your device, and in your iCloud or device backups if you use them.
Fuyomi does not send push notifications or marketing messages. The only notification the app can create is a local reminder two days before a Fuyomi Plus free trial ends, and only after you start such a trial and allow notifications. The current plans do not include a free trial.
Purchases and subscriptions are processed by Apple. We receive no payment details. Manage or cancel them in your Apple Account settings.
Settings → Reset all data deletes your practice history, your game records, your name and the hand you are entering. Your rule settings and your answers to the first-run questions stay. Deleting the app deletes everything.
We'll update this page and the effective date when anything changes.
