BrainTrek respects and protects the privacy of all users who use the Service. This Privacy Policy explains how BrainTrek handles information when you use our brain-training game collection.

Data Collection

BrainTrek collects only the data needed for purchases and ads. All gameplay happens locally on your device and no file content is uploaded to external servers.

Local Processing

• All games run entirely on your device
• No game state, score, or puzzle content is uploaded to any server
• No personal account information (name, email, contacts) is collected
• No analytics SDK is included; ads and purchases are handled by the third parties listed below

Game Center

BrainTrek optionally integrates with Apple’s Game Center for leaderboards and achievements. If you sign in:

• Apple handles authentication and leaderboard data under Apple’s own privacy policy
• BrainTrek only submits your score and reads your rank — it does not access your contacts, photos, or other personal data
• You can play all games without signing in to Game Center

Statistics and Progress

• Game progress, high scores and streaks are stored locally on your device
• You can reset progress at any time through the app settings
• Uninstalling the app removes all associated data

Third-Party Services

BrainTrek uses the following third-party services:

Google AdMob — serves interstitial ads to free users between rounds. AdMob may collect device identifiers, approximate location, and ad interaction data under Google's privacy policy. On iOS, BrainTrek requests App Tracking Transparency; if you decline, ads are non-personalized.
