+                        You can permanently delete your Rosetta account in the app. This action
+                        cannot be undone. Rosetta accounts use cryptographic identities, so no phone
+                        number or email address is required to create or delete one.

+                        Deleting an account removes its local account record, message history,
+                        conversations, cached profile media, and other account-scoped data from the
+                        device where you complete the deletion. It also ends the signed-in session
+                        for that account on that device.

+                        Rosetta is designed so readable message history stays on users&apos; devices,
+                        not as a readable server-side message archive. Encrypted data in transit is
+                        processed only as needed to deliver the service. Deletion does not remove
+                        messages, attachments, or other data that other people have already received
+                        and stored on their own devices.
