Privacy policy
Last updated: 12 November 2026. Applies to Mars Photos for Chrome, version 2.0 and later.
Summary
Mars Photos does not collect, sell or share any personal data. It has no accounts, no analytics and no advertising. The developer receives nothing from the extension.
Connections the extension makes
To show photos, the extension contacts NASA's public servers at mars.nasa.gov. It requests the list of photos for the rover and sol you choose, and then loads the photos themselves. Those requests contain the rover and the sol number and nothing about you. Like any website, NASA's servers see your IP address when your browser contacts them, and handle requests under NASA's own privacy policy.
The extension contacts no other server.
Data stored on your device
The following is saved in Chrome's local extension storage on your device and is never sent anywhere:
- The photos you save: for each one, its web address, rover, camera, sol and date.
- The rover you looked at last.
- The newest sol number for each rover, kept for an hour so it does not have to be asked for again.
Removing the extension deletes all of it.
Permissions
- Storage: to save the items listed above on your device.
- Access to mars.nasa.gov (optional): if Chrome blocks the request for NASA's photo list, the extension asks for this permission once. It is used only to read that list.
Children
The extension does not collect personal information from anyone, including children.
Changes
If this policy changes, the new version will be published on this page with a new date.
