Privacy

Push-up and Plank Coach's privacy rule is simple: your video never leaves your device.

What happens to your video

• It is analysed in your browser, frame by frame, by pose-tracking code that ships with the app. No video is sent anywhere.
• Each frame is discarded as soon as it is checked. Nothing is recorded, uploaded, shared or stored. The app does not identify you: it tracks joint positions, not faces or names.
• The camera is only on while you are in a lesson. It turns off when you go back to the exercise list, press “Turn off”, or switch to another tab.

What is stored on your device

• Which items you have tried, how many times, your points, badges and practice days.
• Your start-position calibration (three numbers: shoulder height, torso length, body length).
• Your settings (sound on or off, confetti on or off) and whether you have seen the welcome message.
• An offline copy of the app, so it works without network after your first visit.
• All of this lives in your browser on your device. There are no accounts, ads, cookies, analytics or trackers.

How to delete it

• On the home page, open Offline proof and press Delete all my data. It shows what was stored before and after.
• Or open Settings and press Clear progress.
• Or clear this site's data in your browser settings.

What the app cannot do

• The app loads nothing from other websites. A security policy (connect-src 'self') blocks connections anywhere else, so the app cannot send data anywhere even if it tried.
• The reference links on the About page open other websites in a new tab. Those sites have their own privacy policies, and Push-up and Plank Coach sends them nothing.
• Like any website, the server that delivers the app's files may keep standard technical logs (such as IP addresses) of those downloads. The app itself sends nothing.

Prove it yourself

Press Offline proof on the home page. It shows a live log of every network request the page makes, lets you simulate a fully offline session, shows exactly what is stored, and deletes it all with one button.
