About this APK

Contacts Backup is an app by Rockstar Developers in the Tools category, listed since at least February 2021. It has no native code, so it runs on any Android processor.

Since version 7.0, the APK grew from 2.4 MB to 3.8 MB and the minimum Android version rose from 4.0 to 5.0. It asks for 11 permissions, 3 of them sensitive: read contacts, find accounts on the device and write contacts. Compared with version 7.0, it adds 3 new permissions (“Access adservices ad id”, “Access adservices attribution” and “Advertising ID”) and drops 1 (“Receive push notifications”). The app can read the advertising ID that ad and analytics services use.
