# Privacy Policy — Mail Launcher (personal browser extension)
Mail Launcher is a personal-use Firefox extension. It does not collect, transmit, or share any personal data with the developer or any third party.
- OAuth access tokens are granted by Google and stored only in the browser's local extension storage on your device. They are sent exclusively to Google's Gmail API to read and manage your own mailbox. - No passwords are ever requested or stored. - No analytics, telemetry, or tracking of any kind. - Account data (message metadata) is cached locally in the browser and never leaves the device except in direct, authenticated requests to Google.
You may revoke the extension's access at any time from your Google Account (security page → Third-party access), and delete local data by removing the extension.
