Data stored in persistent datapath is restored after reinstalling the application

Unity Engine

I store user progress data in a persistent data path. Previously, after uninstalling and installing the application, they were deleted, but at some point they stopped. Reinstalling the application now somehow restores files that were once there, but are no longer relevant. At the same time, if i reinstall the application without an Internet connection, then this data is no restored.

It looks like the application has backed up files somewhere that were once in the persistent data path. But since the application is still in development and even the save data model changes periodically, this data is not needed.

The application exists so far only in the form of an apk file and has not been published in Google Play. In the Google Drive settings, it does not appear as an application whose data needs to be saved. How can these backups be configured? At the moment, they only interfere with development.

There is a configuration ‘android:allowBackup’ in AndroidManifest.xml: <application>  |  Android Developers

And where can I find it?

You can put the custom AndroidManifest.xml (with android:allowBackup set to false) in the Unity project’s folder, Unity will merge it to the builtin AndroidManifest.xml when building the player:Unity - Manual: Android App Manifest

Okay, I think I added. But how can I get rid of that backup that has already been made? It keeps loading.

You (and your users) need to install this new version, and then the backups will subsequently stop.
