1. No Personal Data Collected

SAND does not collect any personal data. We do not ask for or store your name, email address, location, contacts, or any other personally identifiable information.

2. Third-Party Services

To help improve the app and fix issues, we use the following third-party services:

• Amplitude – for anonymous usage analytics
• Sentry – for crash reporting and diagnostics

These services may collect non-personal, anonymous data, such as:

• Device type and OS version
• App version
• General usage patterns (e.g. which features are used)
• Crash data (e.g. stack traces, device state at crash time)

This data helps us understand how the app is used and how we can improve it.

3. Data Sharing

We do not share any personally identifiable data, because we do not collect any. Anonymous usage and crash data may be transmitted to the services above for analytics and debugging purposes only.
