Welcome to Pebble Math. We value your privacy and your child's privacy. This policy explains how information is handled when you use our app.

1. Information We Collect

The current app version mainly uses the following data to support learning features:

• Learning progress data, such as answers, accuracy, review schedule, stage progress, and streak days.
• App settings data, such as grade band, curriculum track, difficulty preference, and daily play limit.
• Subscription status data, such as plan type and active expiration state (payments are processed by Apple).

2. How We Use Information

3. Storage and Transmission

• In the current version, learning data is primarily stored locally on the device.
