Data Security

We take reasonable measures to protect your information:

• Firebase services employ Google's security infrastructure
• We do not store sensitive personal information

Your Rights and Choices

Data Access and Deletion

• We do not maintain user accounts, so there is no central profile to access or delete
• To delete locally stored data (preferences and statistics), uninstall the app from your device

Permissions

The app requests the following permissions:

You can revoke notification permissions at any time through your device settings.
