Terms of use

Luma Mail is an independent, open-source email client for Linux and Windows maintained by SleepyZzed. It is not affiliated with or endorsed by Google. Gmail and Google Drive are services provided by Google.

Early access

The current release is unfinished early-access software. Features and compatibility can change; bugs may affect drafts or mail actions. Review the current limitations and acceptance checklist before using it. A prerelease does not represent completion of all project criteria or Google's verification.

Your account and actions

Only connect accounts you are authorized to use. Luma performs actions against Gmail and Drive under the permissions you grant; sending mail, editing drafts, moving mail to Trash and sharing files can affect your real account and recipients. You remain responsible for reviewing recipients, content, files and sharing choices before confirming an action.

Google's own terms, account controls, quotas and administrator policies continue to apply. Sign-in availability depends on Google. Unverified production access has Google's warning screens and user limits; Luma does not promise unrestricted, uninterrupted or permanent access.

License and warranty

The source and application are distributed under the repository's GNU General Public License version 3, including its warranty disclaimer and limitation of liability. These terms do not replace that license or restrict rights it grants. Nothing here excludes rights or liabilities that applicable law does not allow to be excluded.

Privacy and support

The privacy policy explains Google data access and local storage. Support is offered on a best-effort basis through GitHub issues or mcverdict@gmail.com. Do not publish private mail or credentials in issue reports.
