Hypermobile — EDS Joint Tracker ("the app", "we", "us") is an iOS application designed to help people with Ehlers-Danlos Syndrome, Hypermobility Spectrum Disorder, and related comorbidities track joint events, Beighton scores, daily symptoms, and optional POTS / MCAS data.
Everything you log inside the app — including joint events, daily check-ins, Beighton score assessments, POTS readings, MCAS reactions, and any free-text notes — is stored locally on your device using Apple's SwiftData framework.

The app is not directed to children under the age of 13. We do not knowingly collect any information from anyone, and the app is intended for use by individuals managing their own health data or by a guardian assisting a minor in their care.

Hypermobile — EDS Joint Tracker is a personal tracking tool. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. The data you record is self-reported and should be reviewed with a qualified clinician — it is not a substitute for medical advice, examination, or treatment.
If we ever change this Privacy Policy, the updated version will be posted at this URL with a new effective date. Because the app does not require an account, we have no way to notify you directly — please check back periodically if you want to stay informed.
