All data for this extension is stored locally on your device and is not shared with its developers or third parties. In addition, no analytics data is collected by the developers.

The only time Toolbox communicates with another service is when checking if a given app has been uploaded to APKMirror.com. Only the app's package name (e.g., com.google.android.apps.maps) is sent to the site. This can be disabled entirely by switching the 'APKMirror button' setting to off.
