Settings > Backup & reset gets "Keep mail on this device", off until the user turns it on in this browser. While it is on: - the JMAP client hands the server's answers to an encrypted cache in IndexedDB (AES-GCM, non-extractable key) and answers from it when the network is gone: the folder list, the last 30 days of the Inbox and of the folders the user opened, bodies and attachments, at most 250 MB, oldest out first; a background sync keeps it current - read, flag, tags and moves made offline are queued and sent in order when the server answers again; deleting for good and emptying a folder are refused offline - the composer, quick reply and the S/MIME and PGP plugins' sends that complete the composer's go to an outbox once every step up to the transport ran (checks, label, signature, plugin send checks); only the finished send waits, with files attached offline - the service worker keeps this build's app shell, so the app also starts offline from the kept session and the last policy - a full sign-out, the idle sign-out and signing one account out delete it, a sign-out the user starts asks first when mail is unsent, and the login page names what an automatic sign-out deleted; a policy fetch that forbids it (devices.noOffline) wipes that account Not in Lite.
