MacMail

Privacy Policy

Last updated: October 27, 2026 (added the optional Mail Agent)

MacMail ("the app") is a desktop email client for macOS published by Axisway ("we", "us"). This policy explains what data the app accesses and how it is handled.

Summary

By default MacMail runs locally on your Mac: your mail travels directly between your Mac and your email provider (for example Google), and nothing is sent to us.

If you turn on the optional Mail Agent for a mailbox, that mailbox is additionally processed on an Axisway server and message contents are sent to Anthropic (the provider of the Claude AI model) to sort your mail. This section is off until you enable it, and you can turn it off at any time. Details are below.

Data the app accesses

• Google account data. If you connect a Gmail account, MacMail requests the scopes https://mail.google.com/, openid, email and profile. These are used to read, search and display your messages and folders, mark messages as read, send email you compose, and show your email address and name in the app.
• Other mailboxes. For IMAP/SMTP accounts, the app uses the server address, username and password you enter.
• Credentials. OAuth refresh tokens and passwords are stored only in the macOS Keychain on your Mac. Account settings (server names, email address) are stored in the app's local preferences.

Optional Mail Agent

• What it does. For each new message in the Inbox of a mailbox you enabled, the agent determines a category (for example “needs reply”, “task”, “newsletter”), a priority and a short summary, and applies Gmail labels starting with “MacMail/”. It archives newsletters and automated notifications (removes them from the Inbox; they stay in All Mail) and, for messages that need a reply, saves a suggested reply in your Drafts folder. Every action can be undone. It never sends, forwards or deletes your email.
• What is stored on our server. The OAuth refresh token for that mailbox (encrypted at rest) and a log of processed messages: message ID, Gmail message ID, sender, subject, category, priority, the generated summary and the actions taken. Message bodies and draft texts are not stored on our server (drafts are saved only in your own mailbox).
• Who processes the content. The sender, recipients, subject, date and up to about 8,000 characters of the message text are sent to Anthropic, PBC solely to produce the classification and summary. Messages identified as newsletters or automated notifications from their headers are not sent to Anthropic.
• Where. Servers operated by Axisway (Hetzner, Germany) and Anthropic's API infrastructure.
• Turning it off. Disabling the agent in MacMail settings immediately deletes the stored token and the log for that mailbox from our server. You can also revoke access at myaccount.google.com/permissions, which stops the agent.

How data is used

Data is used solely to provide the email features you use inside the app. We do not sell data, use it for advertising, build user profiles, or use it to train AI or machine-learning models. Anthropic processes the content it receives under its own privacy policy.

Sharing

Without the Mail Agent, the app does not transfer your data to us or to third parties; data is exchanged only with your own email provider. With the Mail Agent enabled, data is shared only with Axisway's server and Anthropic as described above, and only to provide that feature.

Google API Services User Data Policy

MacMail's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Retention and deletion

Removing an account in MacMail (right-click the account → “Remove mailbox”) deletes its stored token or password from the Keychain. You can also revoke MacMail's access at any time at myaccount.google.com/permissions. Deleting the app removes its local preferences.

Security

All connections to mail servers use TLS. Secrets are kept in the macOS Keychain and are never written to plain files.

Children

MacMail is not directed to children under 13.

Changes

We may update this policy; the date above shows the latest revision.
