zetox-mail privacy policy

Effective 13 September 2026.

What zetox-mail is

zetox-mail is a desktop application (a Thunderbird extension with a companion helper program) that runs entirely on the user's own computer. It is published by zetox.dev, Hamilton, Ontario, Canada. Contact: [email protected].

Google user data

When a user chooses to connect a Google account, zetox-mail requests access to Google Calendar (read and write events), Google Tasks (read and write task lists and tasks) and Google Contacts (read contacts). It uses this access solely to show and edit the user's own calendars, tasks and contacts inside the application.

Where the data goes

• Data retrieved from Google is displayed on the user's computer and may be cached locally on that computer to make the application faster. It is not transmitted to zetox.dev or to any other party.
• OAuth tokens are stored in a file readable only by the user on that computer. The user can revoke them at any time from the application's settings or from their Google Account permissions page.
• zetox.dev operates no server that receives, stores or processes Google user data. There is no analytics, advertising or tracking of any kind.

Limited Use

zetox-mail's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is used only to provide the user-facing features described above; it is never sold, never used for advertising, and never read by humans except by the user.

Other data

Email, notes and files handled by zetox-mail stay under the user's control on their own systems (their mail provider, their computer, and any server the user operates themselves). The application never phones home.

Changes
