Privacy and assessment scope

Questions run on this page without requiring your name, phone number or intimate images. You may add a first name for the displayed report; it stays on your device and is not sent to AI. Optional AI assessment sends your answers and text to Cloudflare only with your consent; files are sent when you request extraction. Remove identifiers before upload. The app creates no permanent medical record and no clinician reviews the output. Answers do not persist after reload and are not sent automatically to the clinician. WhatsApp is an external service; the booking button does not attach medical answers. Saved or copied reports contain health information: review them and choose who to share them with.

App files may be cached locally for offline use; this does not include assessment answers. Hosting services process ordinary web requests under their policies. Guidance is automated education, not a diagnosis, prescription or clinician-issued report.
