Mound Metrics AI runs entirely client-side, in your browser. When you upload a video, it is loaded directly into the browser and processed there by an on-device pose-detection model. There is no upload step, no video storage server, and no account for us to attach a video to even if we wanted to.
These are stored using your browser's built-in local storage (IndexedDB / localStorage), on your device only. They persist between visits so you can reload a saved analysis, and they're removed if you clear your browser's site data for this page. We have no way to see, access, or recover this data — it never reaches us.
| Item | What it is | Why |
|---|---|---|
| Pose-detection model files | A one-time download of the AI model from a third-party CDN (jsDelivr), cached by your browser | Needed to run pose detection locally — no video or personal data is included in this request |
| Anonymous page visits | A basic, cookie-free visit counter (page viewed, rough browser/OS type, referring site) | So we can see how many people use the app — see below |
We use a privacy-focused analytics service to count visits. It does not use cookies, does not build advertising profiles, and does not track you across other websites. It cannot see your video, your inputs, or anything you do inside the app — only that a page on this site was loaded.
There is nothing to sign up for. We don't collect names, emails, or any other personal information, and there's no server-side database of users.
This site is hosted on GitHub Pages and loads the pose-detection model from the jsDelivr CDN. Both may log basic technical request data (like IP address) as part of normal web infrastructure operation — this is standard for any website and outside our control, and is covered by their own policies, not ours.
The app includes an age-range option for describing a pitcher being analyzed, which is not the same as collecting data from a child user. No personal information about any pitcher, of any age, is collected or transmitted by this app.
If this policy changes, we'll update the date at the top of this page.
