Hanabi is a daily Japanese word-puzzle game. You can play every day without an account. Some optional features (friends & private leagues) require signing in. This policy explains what we collect and why.
We do not collect advertising identifiers, location, contacts, or any data for advertising. Hanabi contains no ads and no third-party ad tracking.
Data is used solely to run the game's features (puzzles, stats, friends, leagues). We use Google Firebase (Authentication and database) as our service provider to store accounts and results; Google processes this data on our behalf. We do not sell your data or share it with advertisers. All network traffic is encrypted in transit (HTTPS).
The optional daily reminder is a local notification scheduled on your device. We do not run a push server and do not need your data to send it.
You can delete your account at any time in the app: 設定 (Settings) → アカウントを削除
(Delete account). This permanently removes your profile, friends, and league memberships
from our servers and deletes your sign-in account. You can also request deletion by email (below).
Account and results data is kept while your account exists and is removed when you delete your account. Anonymous aggregate stats (counts with no link to you) may be retained.
Hanabi is not directed to children under 13. We do not knowingly collect personal information from children.
