Your privacy

At the end of the symptom check, you choose whether to save your answers. If you check the box, we save:

• Your answers to the questions (like how many days you have been sick and which symptoms you have).
• The result of the cough check: whether a cough was heard, and whether it sounded dry or wet.
• The results we showed you (how soon to see a doctor, and your valley fever signal).
• A survey ID and a scrambled (hashed) version of your PIN. We never save the PIN itself.

If you don't check the box, nothing is saved. You still see your results, but you get no ID, PIN, or QR code.

• Your voice recording. It is checked for a cough and then deleted right away.
• Your location. “Use my location” only builds a Google Maps link on your phone. It is never sent to us.
• Chest X-rays and anything a doctor types in. These are used once to calculate the doctor's assessment and then thrown away. The doctor's PDF is their record.
• Your name, email, phone number, or address. We never ask for them.

Anyone who has both your survey ID and your PIN can see your saved answers. That is how your doctor sees them. So only share your card with your care team.

The QR code only contains the survey ID, not the PIN. After 5 wrong PIN tries, that ID is locked for 15 minutes. The ValleySense team can access the database to keep the app running, but does not look at individual answers.

Saved answers are deleted automatically after 30 days. After that, the ID and PIN stop working.

• All traffic is encrypted (HTTPS).
• The database is locked so only our server can read it, never a browser directly.
• To stop people from guessing PINs, we count requests from each network for 15 minutes. We store a scrambled (hashed) version of the network address, never the address itself, and erase it after 15 minutes.
• A doctor's access lasts 30 minutes on that browser, then they must enter the PIN again.

• Vercel hosts the website.
• Supabase stores saved answers (in the United States).
• Hugging Face runs the cough and X-ray models. It receives the recording or X-ray only to analyze it.
• Google Maps opens only if you tap a “near me” link. Google's own privacy policy applies there.

We don't use advertising or tracking cookies. Your browser remembers your light or dark theme choice on your device. Doctors get one short-lived cookie that keeps the briefing open.
