Privacy Policy

Sudoku Evolved is a single-player puzzle game with optional online features. You can play without an account. If you sign in, we sync your progress and let you appear on leaderboards and in friend duels. We don't sell your data and we don't show ads.

• Game progress: levels cleared, stars, crowns, time-trial scores, streaks. Stored locally; synced to our backend (Supabase) when you sign in.
• Profile: display name, username, avatar (if you set one), and an account ID. Visible on public leaderboards and public profiles unless you switch your privacy level to "friends" or "private."
• Sign-in identifier: when you sign in with Apple or Google, we receive a stable identifier from the provider. We do not store your password.
• Diagnostic data: crash logs and minimal performance telemetry to keep the app stable. Not associated with your account beyond what your platform (iOS) provides.

• We don't sell or share your personal data with advertisers.
• We don't serve ads.
• We don't track you across other apps and websites.

• Supabase hosts our database, authentication, and real-time duel rooms.
• Apple and Google handle sign-in if you choose to use them.

• Privacy level: in-app, switch your profile between Public, Friends, and Private.
• Delete: in-app, request account deletion under Settings → Account → Delete account. See the delete-account page for details.
• Email: write to support@sudokuevolved.com with any privacy question or request.

Sudoku Evolved is not directed at children under 13. If you believe a child has provided us with personal data, contact us and we will remove it.

We'll update this page if we change our practices. Material changes will be reflected with a fresh "Last updated" date and, where appropriate, an in-app notice.
