Privacy Policy

Puzzle provides web and PWA puzzle gameplay, account profiles, streak tracking, leaderboard features, and optional push notifications. This policy explains what data we collect and how we use it.

• Account data: authentication identifiers and email from our authentication provider.

• Gameplay data: game sessions, results, challenge participation, streak events, and aggregate totals.
• In-app economy data: puzzle points, freeze balance, and ledger events tied to your account.
• Push notification data (optional): web push subscription endpoint and keys when you opt in.
• Usage analytics: page and event analytics via analytics providers.

Push notifications are optional. If enabled, your browser/device push subscription is stored so we can deliver notifications. You can unsubscribe from notifications in app settings or your browser settings.

We do not sell personal data. We share data only with service providers needed to operate the app and when required by law.

We retain account and gameplay data while your account remains active, and as needed for app integrity, fraud prevention, and legal obligations.

• Update profile details in the Profile page.
• Disable push notifications anytime.
• Request account/data deletion by contacting us.

We use reasonable technical and organizational safeguards, but no system can be guaranteed 100% secure.
