Mark & Prompt does not collect, sell, or transmit personal data.

Images are processed locally in Firefox. When you right-click an image on a website, the extension may request that exact image URL so it can display and annotate it. The extension does not upload your images to any server.

To open the editor, the extension may temporarily store the selected image or image URL in Firefox's local extension storage on your device. This temporary handoff data is deleted when the editor opens (and automatically within two minutes in any case). Your settings are also saved locally in Firefox extension storage.

No analytics, tracking, accounts, or third-party services are used.
