Where Does R2Mail2 Store Keys and Accounts on Android?
Where R2Mail2 keeps PGP keys, accounts and mail cache on Android for backup and migration.
Last updated
R2Mail2 splits Android state two ways: mail accounts with cache in app private storage, and PGP keys that move only through manual export. Server mail resyncs; keys never travel by themselves on any phone.
Export keys before anything else; everything depends on them. Package name can vary by build, so prefer in-app flows over file browsing. Passwords always need re-entering on the new phone you own, without exceptions.

Frequently asked questions
How do I move R2Mail2 to a new phone?
Re-add each mail account plus PGP keys on the new phone and let folders resync. Keys travel only through export files, never automatically. Back up keys before wiping the old phone.
How do I back up R2Mail2 PGP keys?
Open R2Mail2 key management and export keys to files, then move those off the phone. The export plus its password restores signing. Without exported keys, encrypted mail stays unreadable.
