Posture & Body-Structure Self-Assessment
An educational self-assessment — not medical advice, and not a diagnosis.
This tool helps you see how your body lines up in a photo, so you know what to look for and what to ask about. It doesn't identify a single cause, and it isn't a substitute for professional care.
Your photo never leaves your device — all processing happens right here in your browser. No image or coordinate data is ever transmitted or stored.
Ear position is used only as a posture reference point, never for identification.

Posture Assessment
Pick one view to capture. Add the others whenever you're ready — each is its own quick photo.
Side photo
Place the camera to your side and stand naturally. Frame yourself from head to feet.
Photographing or recording someone else? Please get their consent to capture and keep the record first.
Tip: a door frame or pillar in the background makes leveling easier.

Privacy Policy
Body Line is a local-only tool. This page explains, in plain terms, how your data is (and isn't) handled.
Everything stays on your device
Photos, videos, and records you create in Body Line are stored only in this browser, on this device (IndexedDB). Nothing is uploaded to a server — there is no server. We never see your photos, videos, or records.
Consent is your responsibility
If you photograph or record someone else (e.g. a client or member), it's your responsibility to get their consent before capturing and keeping that record.
Educational tool, not medical advice
Body Line is an educational recording/observation tool. It is not medical advice, not a diagnosis, and not a substitute for professional care.
You control your data
Everything is stored on-device only, and you can delete any client, folder, or item at any time from the Library. Clearing your browser data or uninstalling the app also removes it — there is no copy anywhere else, so back up anything you want to keep (Settings → Export full backup).
