## Frequently asked questions
### What counts as a jumping jack in this app?

A complete cycle: start at rest with arms down and feet together, then arms overhead (both wrists above the shoulders) AND feet out (ankle spread at least 1.8 times shoulder width), then back to rest. Arms up without feet out, or feet out without arms up, is rejected with the named hint.

### What counts as a squat?

Hips drop at least 35% of leg length with knees bent to 110 degrees or less, then hips return to a full stand with knees opened to 160 degrees or more. A shallow dip is rejected with Go lower; coming up without straightening the legs is rejected with Stand all the way up.

### What counts as a star jump?

Both feet leave the floor (at least 4% of body length up) with arms wide and legs wide in a full star, then land and reset. Spreading your limbs while standing is rejected: the hint says your feet never left the floor.

### How does stretch mode work?

Good-form seconds accumulate only while the stretch position holds: overhead reach needs both hands up with a tall stand; side bends need the lean plus one arm overhead. The moment the shape breaks, the good-form clock pauses and the named hint appears, while total elapsed time keeps running.

### Why do half reps not count?

Because a half rep never completes the movement the exercise is for. The app rejects part-way attempts with the named hint, so every counted rep is a full rep and your count stays honest.

### How do I set up the camera?

Jumping jacks, star jumps and stretches use the front view: face the camera about 2 metres away so it sees your whole body. Squats need the side view: put the camera to your side, because only the side view shows how low your hips go. Clear the space around you and use good light.

### Can a whole PE class use it at once?

One person at a time. The app tracks a single body, so take turns: one student practises while the camera watches, then the next. It never asks for a name and never stores a photo.

### Does the app record video or store names or photos?

No. Video frames are analysed on your device and discarded immediately. Nothing is recorded, uploaded or shared, and the app never asks for a name or saves a photo. The page security policy blocks connections to every outside server, and the Offline proof panel shows the live request log to prove it.

### Does it work offline?

Yes, after your first visit. The app, the pose model, and all the lessons are saved on your device, so it works with no network at all, which helps in school gyms with patchy wifi.

### How do points, levels and badges work?

Each clean rep is +10 points, each good-form stretch second is +1, and a passed quiz adds +20. Levels are First Rep, Warming Up, PE Star, and Rep Machine. Exercise levels unlock at 50 and 150 points. Badges cover the first clean rep, the first stretch hold, a perfect set, thirty seconds, a passed quiz, the full PE circuit, and a 7-day streak.

### Can I delete my progress?

Yes. Open Offline proof on the home page and press Delete all my data, or open Settings and press Clear progress. Everything is stored only in your browser, on your device.

### Is this a fitness assessment?

No. This is a home practice tool, not a fitness assessment, teacher, therapist, or safety device. Stop if anything hurts, follow school safety rules, clear the space around you, use with teacher supervision at school, and check with a doctor or qualified professional before exercising if you have a health condition, an injury, or pain.
