    General guidance from repository metadata, not legal advice. How we score

    From the README

    Alpha software. APIs, storage format, and CLI flags may change without notice. Back up your data.

    Archive a lifetime of email, messages, meetings. Analytics and search in milliseconds, entirely offline.

    Your messages are yours. Decades of correspondence, attachments, and history shouldn't be locked behind a web interface or an API. By default, msgvault downloads a complete local copy and then everything runs offline. Search, analytics, and the MCP server all work against your msgvault archive with no mailbox network access required. If you configure a remote deployment, the archive lives on your own server rather than a hosted msgvault service.

    Currently supports Gmail, Google Calendar, Microsoft Teams, Discord, Slack, Granola, Circleback, Beeper Desktop, and IMAP sync, plus offline imports from MBOX exports, Apple Mail (.emlx) directories, PST archives, and common chat/text export formats.
