Shichijin (七陣) is a single-player puzzle game with an optional online leaderboard. We keep data collection to the minimum needed to run that leaderboard.
No real name (unless you type one), no location, no contacts, no advertising identifiers, and no third-party analytics or ad tracking. We include no ad or tracking SDKs. If you use Sign in with Apple and choose to hide your email, we only ever receive Apple's private relay address, and we do not use it for marketing.
Koban (in-game currency) and the Sensei Pass (an auto-renewing yearly subscription for unlimited analysis) are purchased through Apple's App Store. Apple processes the payment and manages any renewal; we never see your card or payment details.
Leaderboard data is stored on Supabase (EU region). It is used only to display the daily leaderboard and world ladder — your chosen display name and score are visible to other players; nothing else is shared.
You can play entirely offline; the leaderboard is optional. To request deletion of your leaderboard entry, email us and include your display name.
Shichijin is a general-audience game, suitable for all ages. It is not aimed at children and does not knowingly collect personal data from children under 13.
