Google and Microsoft Data Use

Last updated: November 2026

When you sign in to Mailzo with Google or Microsoft, you give Mailzo permission to access your email and, if you choose, your calendar. This page explains how that access is used. It adds to our Privacy Policy.

What access Mailzo asks for

  • Email: to read, send, organise and delete your email, as any email app does
  • Calendar (only if you connect it): to show, add and change your events
  • Out-of-office settings: to turn your auto-reply on or off when you ask

How the data is used

  • Your Google and Microsoft data goes straight between your Mac and Google or Microsoft. It's stored on your Mac, encrypted, and is never sent to Grayic's servers.
  • Data is used only to provide the features you see in Mailzo.

Google API Services User Data Policy

Mailzo'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.

In particular, Mailzo:

  • Uses Google user data only to provide and improve the email and calendar features you use in Mailzo
  • Does not transfer Google user data to others, except when you choose it (for example, to the AI service you pick, when you turn on an AI feature), to comply with the law, or as part of a merger or sale with notice to you
  • Does not use Google user data for advertising
  • Does not sell Google user data
  • Does not let people read Google user data. Grayic has no access to it, because it stays on your Mac.
  • Does not use Google user data to train general AI or machine learning models
