This privacy policy describes how MNEMONIC: Daily Puzzle (the "App") handles information.

What we collect

• Anonymous gameplay data — daily seed completions, puzzle ratings, and leaderboard scores tied to a randomly generated player ID.
• Account data (optional) — if you create an account to sync progress across devices: username, password (hashed), and email address.
• Crash and error reports — diagnostic data via Sentry to fix bugs.
• Advertising data — Google AdMob may collect device identifiers to serve ads. You can opt out in your device settings.

What we don't collect

• We do not collect contacts, photos, location, microphone, or camera data.
• We do not sell or share your personal data with third parties for marketing.
