vortex

The android.permission.ACTIVITY_RECOGNITION permission is a core requirement for the primary functionality of Vortex. The application is a dedicated step counter and daily walker tracker. It utilizes this permission solely to interface with the user's device-native hardware step-counter sensors.

This access allows the app to accurately detect real-time walking movements, calculate daily step counts, and measure active progress toward user-defined fitness goals. Vortex processes all sensor data instantly and exclusively on-device using local storage. The movement metrics are never collected in the background maliciously, tracked across other apps, or transmitted to external cloud servers, ensuring absolute user privacy and data security.
