Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.

What’s new

Sensitivity presets added: choose Low, Medium, or High to quickly set the right detection level for your use case. Advanced users can still enter a custom value or use calibration.

Friendlier terminology throughout the app — Start Protection / Stop Protection instead of Arm / Disarm, and clearer labels in Settings.
