MatrixTimer is primarily a local utility tool.

Personal Data: We do not require you to create an account or provide personal information (such as your name or address) to use the core functions of the App.

Non-Personal Data: We may collect non-identifiable technical data (e.g., device model, OS version, app usage statistics) via third-party analytics tools to improve App performance.

To provide professional timing services, we may request the following permissions:

Notifications: To alert you when a timer expires while the App is in the background.

The security of your data is important to us. Since most data (timer settings, lap history) is stored locally on your device, it remains under your control. We do not upload your timing logs to our servers.
