Privacy Policy

Last updated: 16 September 2026

The short version: your photo is never uploaded. It is read and measured inside your own browser tab, and it is gone when you close the tab. No account is needed and none is created.

1. Your photo

When you choose, drop or shoot a photo, the file is read by the page running in your browser. The face landmark model runs locally on your device and produces the measurements in the same tab. The photo is not sent to this site's servers, because there are no servers that accept photos. This site is a set of static files hosted on a content delivery network; it has no application backend, no database and no upload endpoint.

Nothing is stored on your device either: no photo, no measurement and no result is written to disk or kept after you close or reload the page. That also means there is no history to delete — there was never any history.

2. What is collected

No accounts and no personal data. There is nothing to sign up for and no form that asks who you are.
No analytics scripts. This site currently does not run any analytics or tracking product.
No cookies set by this site. The detector works without them.
Server logs. The hosting and network provider (Cloudflare) processes the requests needed to deliver these files, and like any web host it can record standard technical data such as IP address, user agent and time. That is inherent to serving a web page and is outside this site's control.

3. Advertising

This site intends to display third-party advertising in the future. It does not do so yet — there are no ad scripts on any page today. When advertising is added, this section will be updated before or at the same time, and it will name the ad provider and explain what that provider may collect, typically through cookies or similar identifiers, and how you can opt out. If you want to know before that happens whether ads are live, the honest test is to look at this paragraph: it will say so plainly.

4. Children

This site is not directed at children and does not knowingly collect information from them.

5. Your choices

Do not upload a photo you are not comfortable measuring in your own browser.
You can use the site with JavaScript disabled only if you accept that the detector will not run — the measurement is the page.
Clearing your browser data removes anything cached from this site, as it does for any other site.

6. Changes

If this policy changes, the date at the top changes with it. Material changes — advertising being the obvious one — will be described in this document rather than quietly added.

7. Contact
