FAQ

How does AppGuard work?

AppGuard allows you to monitor your installed applications and revoke some of their permissions. Therefore a
security library is added to the application and the apps gets re-installed.

Why do we lose the data when monitoring an app?

Since AppGuard works without root privileges, monitored apps have to be replaced. All data of the app gets
lost once when uninstalling the app.

Which permissions can be monitored with Appguard?

Currently the following permissions can be monitored: Call phone number, send SMS, access your camera, Internet access,
location access, access to your contacts, calendars und messages.

Which permissions can not be monitored with Appguard?

Currently only functions called via the official Android API can be monitored. We do not support to monitor
functions called via native code.

Why can system apps not be monitored?

Pre-installed system apps can not be monitored, because the Android operating system does not allow to uninstall and
replace those apps.

Why do monitored apps not show maps?

Monitored apps currently don’t get access to the maps provided by Google Maps.

Do monitored apps receive updates?

Monitored apps that got installed via the Google Play Store are updated by AppGuard. A update via the Google Play Store
is not possible anymore for monitored apps. Please select your Google account in the settings of AppGuard, such that AppGuard
can check for updates.

Can monitored apps from version 1.x be ported?

Depends. Already monitored apps can be ported to the current version if two conditions are met. First, there has to be a backup of the original app
or the original app must be retrievable from Google Play (only possible if a Google account is set). Backups are missing if for instance the user
manually deleted the backups (for saving space). Second, for being able to port apps, version 1.1.7 has to be installed that is able to automatically
prepare apps for migration. You can get version 1.1.7 by going to settings and searching for app updates.

Why does porting monitored apps from version 1.x always fails?

If the migration of all monitored apps fails, you most probably do not have version 1.1.7 installed. This version is necessary to
prepare monitored apps for migration. You can update to version 1.1.7 by searching for updates in the AppGuard settings. Then, porting the monitored
apps with the current version should work as expected.

Is the app data lost when porting an app?

Already monitored apps can be ported without data loss if SRT AppGuard 1.x has not been de-/re-installed before the apps have been ported.
