Allow secure backup

[jcz1]

Hello.

I use SeedVault (integrated in LineageOS, GrapheneOS etc.) for secure (encrypted) backup apps and data to my device (USB) or my server (NextCloud).

But Simpleask is opted-out from backups so it is not possible to save data by SeedVault :( Please can you allow encrypted backups? There is more info:

And an example of commit:

Thanks.
