Your face never leaves your device.

An email address, only if you choose to join the waitlist. Nothing else is required to use Fitlens.

Anonymous, aggregated usage counts such as how often a measurement is completed. These carry no identifier that points back to you.

We never receive your photo, your camera stream, or your face geometry. Measurement runs entirely on your device, inside your browser.

We do not build biometric profiles, and we do not sell or rent any data to third parties.

Your face width is stored locally on your device. It is used to filter frames on the stores you visit, and it leaves your device only if you explicitly choose to sync it in a future release.

Clearing your browser storage removes the measurement permanently. We keep no server-side copy to restore.

You can request deletion of your waitlist email at any time by writing to hello@fitlens.online. We remove it within 30 days.

Fitlens is built to be GDPR compliant by design: the smallest possible amount of data, processed on-device wherever technically possible.
