Privacy policy
Your swings stay on your phone.
Effective October 31, 2026. Applies to the SwingLab app for iPhone and this website.
The short version
- No account, no ads, no analytics, no tracking.
- Swing videos, measurements and settings are stored on your iPhone, not on our servers. We don't run any servers for the app.
- We only receive something if you choose to email us or send feedback from the app.
What the app uses, and why
| Data | Why | Where it goes |
|---|---|---|
| Camera | Watching for your swing, recording it, and tracking your body position. | Processed on your iPhone with Apple's on-device frameworks. Saved clips stay in the app's storage on your phone. |
| Swing videos and measurements | Replays, stat cards, still frames, trends and your swing history. | On your iPhone. Videos are left out of iCloud backups unless you turn on "Include clips in iCloud backup" in Settings. |
| Local network | The optional range display, which plays your swings in a browser on the same Wi-Fi, and its live camera view if you turn that on in the browser. | Sent directly from your iPhone to that browser over your network, only while the range display is on (the live view only while a browser has it switched on). It never goes over the internet. |
| Settings | Remembering your camera angle, handedness, replay length and display choices. | On your iPhone. |
Sharing
When you share a swing, the app makes a video and hands it to the iOS share sheet. Where it goes from there is up to you and the app you pick. Nothing is shared unless you choose to.
Subscriptions
SwingLab subscriptions are bought, renewed and cancelled through Apple. We never see your name, card or payment details; the app only asks Apple, on your device, whether your Apple Account has an active subscription.
Beta testing
If you test SwingLab through TestFlight, Apple may share crash reports and any feedback you send with us, as described in Apple's TestFlight terms. We use them only to fix problems.
Feedback from the app
If you send feedback (Settings › Send feedback), we receive what you type, plus the app version, your device model and its iOS version. You see all of it before you send. It's filed as an issue in our private project on GitHub (run by GitHub, Inc.) so we can track and fix it. Swing videos are never included, and nothing is sent unless you tap Send.
If you email us, we use your email address and what you write only to reply. We don't add you to a mailing list.
This website
This site is a set of static pages hosted by Vercel. It uses no cookies, analytics or tracking scripts. Like any web host, Vercel may keep standard server logs, such as IP addresses, for security. Fonts are loaded from Google Fonts.
Children
SwingLab isn't directed at children under 13, and it doesn't knowingly collect anything from them.
Deleting your data
Delete a swing from its replay screen, or delete the app to remove everything it stored. If you turned on iCloud backup for clips, those copies are managed in your iCloud settings.
Changes
If this policy changes, we'll update this page and its date. If the app ever starts sending your data anywhere new, it will ask you first.
