Privacy
We never upload video of your kid.
Privacy isn't a policy we bolted on, it's the way the app is built. SwingDino turns a swing into numbers on your phone, in real time, and throws the video away. Here's exactly what that means.
The short version
No video or photo of your hitter is ever stored or sent anywhere, not for the speed reading, not for the swing analysis. The frames exist for a few thousandths of a second in the phone's memory, get measured, and are discarded. We keep only numbers, the swing results and the coordinates we use to draw a stick figure, on your device. That boundary is enforced in the app's code, not just promised here.
The camera measures, then forgets
When you hit, the phone analyzes a few thousandths of a second of motion in memory to compute your numbers. Those frames are never written to storage and never leave your phone. By the time you see your exit velo, the footage is already gone.
Swing analysis is points, not pictures
To read your mechanics, SwingDino records the positions of a handful of body joints as plain x,y coordinates, dots on a grid, using on-device pose detection. From those dots we redraw your swing as a stick figure. We save the math behind the stick figure, never a photo or video of the child who made it.
We keep numbers, not footage
Everything stored is small and on your device: your hitter's nickname, age band, each swing's metrics and grades, and the joint coordinates for the stick figure. A few hundred bytes per swing, not a video, and nothing that shows what your child looks like.
You're in charge, and you can delete it
Hitters are set up and managed by a parent. You can see exactly what's stored and delete any hitter's data, the numbers and the stick-figure coordinates, right on the device, any time. We keep it only as long as it's useful to you.
No ads, no selling, no tracking your kid
We don't sell or share your data, we don't run behavioral or targeted advertising, and we don't build advertising profiles of children. The app's job is to measure swings, not to monetize the kids taking them.
Built for kids (and the rules that protect them)
A lot of our hitters are children, so we built around the law from day one. Under the U.S. children's privacy rule (COPPA), things like a photo, video, or audio of a child, and, as of the FTC's 2025 update, a child's biometric identifiers, count as personal information that's tightly protected. Our answer is to not collect those things at all: we measure in memory and discard, so there's no image, recording, or face data to safeguard in the first place. Parent-managed setup, on-device storage, and one-tap deletion are there because a child's data deserves that care.
This website
We use privacy-friendly analytics to see which pages people find useful, in aggregate. We don't use invasive cross-site trackers, and we don't put personal information in links or sell anything about your visit.
This is the plain-English version of how we handle data, written to be readable rather than lawyerly. We'll publish the formal, legally-reviewed policy before launch. Questions about your data? Email hello@swingdino.com or see the FAQ. Last updated June 2026.
