Privacy policy
Last updated 13 November 2026
Mail Notifier is a Mac menu bar app that notifies you about new Gmail messages. It runs entirely on your Mac and connects only to Google's Gmail API. This policy explains what Google account data the app uses and what it does with it.
Data the app accesses
When you sign in with a Google account, you grant Mail Notifier these permissions:
gmail.modify: to read message metadata and previews for notifications, follow changes to your mailbox, and mark messages read, archive them or move them to Trash when you ask.gmail.settings.basic: to create, list and remove the Gmail filters that power auto-cleanup rules.
The app never deletes mail permanently. Messages it moves to Trash stay there for Gmail's usual 30 days.
Data stored on your Mac
- Google sign-in tokens, stored in the macOS Keychain.
- Message IDs and their notification state, so dismissed notifications don't come back.
- Sender addresses and counts of messages deleted without being opened, used to suggest and create auto-cleanup rules.
- The auto-cleanup rules you have, and the senders you've marked as never to be auto-trashed.
All of this stays on your Mac. Signing out of an account removes its tokens and stored data.
Sharing
Mail Notifier has no server, analytics or advertising. It doesn't send your Gmail data to the developer or to any third party, and doesn't sell or transfer it. The only network requests it makes are to Google's sign-in and Gmail API endpoints.
Google API Services User Data Policy
Mail Notifier's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Revoking access
You can sign out of an account in the app at any time. You can also remove Mail Notifier's access from your Google account at myaccount.google.com/connections.
Changes
If this policy changes, the date at the top of this page will change too.
