 ### Public API
 
-OpenTracks includes an API for starting/stopping recording by another installed application (e.g., [Automate](https://llamalab.com/automate/), [Tasker](https://tasker.joaoapps.com), or [Easer](https://github.com/renyuneyun/Easer)). 
-The API is disabled by default to protect the user's privacy, but it can easily be enabled in the settings. Once enabled, the API can be invoked by sending an explicit Intent to start an activity.
