Privacy Policy

Information We Collect

• Gameplay and progress data, including highest chapter, coins, inventory items, solved-board count, streak, Pro status, selected theme, accessibility settings, selected locale, and gameplay counters.
• Account data if you sign in, including Firebase user ID, email address or display name provided by your sign-in provider, and synced gameplay progress in Cloud Firestore.
• Guest progress while you play without signing in. Guest progress is stored locally and can be moved into your account when you sign in.
• Purchase data such as DriftMind Pro purchase or restore status, product identifier, RevenueCat entitlement status, and store purchase state. Payment details are processed by Apple or Google and are not stored by DriftMind.
• Advertising data related to AdMob banner and rewarded ads. Ad personalization and device identifiers are handled by Google according to your device and Google settings.

How We Use Information

• To save puzzle progress, coins, inventory, streak, language, accessibility, and theme preferences.
• To provide sign-in, sign-out, account deletion, and cross-device progress sync when you connect an account.
• To move guest progress into your account when you sign in.
• To make market items work, including Memory Lens, Truth Flash, Rule Shield, and Clean Slate.
• To restore DriftMind Pro benefits and apply premium features such as daily archive access, expert boards, premium themes, daily tool kit, progression rewards, and discounted market items.
• To show ads to non-Pro players, including rewarded ads that grant Drift Shards.
• To improve gameplay balance and app stability.

Third-Party Services

DriftMind uses third-party services that may process data under their own privacy policies:

• Firebase Authentication
• Cloud Firestore
• Google Mobile Ads / AdMob
• RevenueCat
• Apple App Store and Google Play billing services
• Google Sign-In and Apple Sign-In

Data Sharing

We do not sell personal information. Data may be shared with service providers only as needed to operate sign-in, sync progress, process purchases, restore Pro entitlement status, and show ads to non-Pro players.

Data Retention

Guest progress may remain on your device until you delete the app, reset local data, or move that progress into an account by signing in. Account-linked progress remains in Cloud Firestore until you delete your DriftMind account or request deletion. Purchase, authentication, and advertising records may be retained by Apple, Google, Firebase, AdMob, or RevenueCat according to their policies.

Your Choices

• You can continue as a guest or sign in with a registered account.
• You can sign out from the app without deleting your account.
• You can delete your DriftMind account from the app. The delete option is placed under advanced account controls and asks for confirmation before continuing.
• You can manage ad tracking and privacy preferences through your device settings.
• You can restore purchases through the app store purchase restore flow.

Children

DriftMind is not intended for children under 13. If you believe a child has provided personal information, contact us so we can review and delete the information where appropriate.

Security

We keep guest gameplay progress local until sign-in, use Firebase security rules for account sync, and use platform billing services for purchases. No method of electronic storage or transmission is completely secure, so we cannot guarantee absolute security.

Changes

We may update this Privacy Policy as the app changes. The effective date above will be updated when material changes are made.
