Affected app version

1.1.3

Affected Android/Custom ROM version

CalyxOS 5.9.0

Affected device model

Moto G52 "rhode"

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Try filling the app with image cache, this seems to be included and likely to cause an issue
2. Use a backup solution like Seedvault (D2D mode on or off) or Google device backup

Expected behavior

Only things like settings, preferences, etc, should be included in the backup, things like image cache should not.

Actual behavior

App seems to not filter out cache and such, leaving the backup size quite big In my case, it was using 50MB until I cleared it.

Screenshots/Screen recordings

No response

Additional information

Google's backups are limited to 25MB, Seedvault allows up to 50MB, or unlimited if you change an expert setting. Exceeding this limit means the app is not backed up at all.

Ideally to me this would also apply to D2D backups, not just cloud backup! I'd help a bunch of users of Seedvault which use D2D mode in order to get more apps to back up.
