We collect the following types of information:
- Account information: When you create an account, we collect your email address to authenticate you and provide access to your data across devices.
- Practice data: We store your practice sessions, including practice fragments, BPM logs, session duration, and related metadata you generate while using the App.
- Device and usage data: We may collect basic device information, app version, and anonymized usage analytics to improve the App.
How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the App and its features

- Send push notifications related to practice reminders (if enabled)
- Respond to support requests and communicate with you

Third-Party Services
We use trusted third-party services to operate the App. These providers process data on our behalf and are bound by their own privacy policies:

Data Security
We implement industry-standard security measures to protect your information. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
