Mail Bridge privacy policy
Effective November 10, 2026
What Mail Bridge is
Mail Bridge is a personal tool that runs only on its owner's computer. It connects the owner's own email accounts to the owner's AI assistant. It is not a public service.
What data it accesses
When an account owner signs in and approves access, Mail Bridge can read, search, label and draft messages in that account, and send messages only if the owner turns sending on. It uses the Gmail API (scope gmail.modify) and, for Microsoft accounts, Microsoft Graph (Mail.ReadWrite, Mail.Send, User.Read).
Where data goes
- Email data is fetched directly from Google or Microsoft to the owner's computer, and is shown only to the owner and the owner's AI assistant at the owner's request.
- Sign-in tokens are stored in the owner's computer keychain.
- No email data is sent to the developer, sold, shared with third parties, or used for advertising.
- Use of data received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements.
Removing access
Any account can revoke access at any time: Google at myaccount.google.com/permissions, Microsoft at myapps.microsoft.com. Removing an account from Mail Bridge also deletes its stored token.
