What MedVault is
MedVault stores a household's medical records — prescriptions, lab reports, discharge summaries, doctor visits, and a written thread about an illness as it happens. It is a filing cabinet with a good index, run by Greyfeathers (greyfeathers.io).
What it is not
It is not a medical device, and nothing in it is medical advice. The “look back over this” feature reads an episode and writes a summary, a timeline, and a list of things worth asking a doctor. It is a language model reading what your family typed. It can be wrong, it does not know anything your family did not write down, and it must never be used to decide whether to take a medicine, change a dose, or skip seeing a doctor. If somebody is unwell, call a doctor.
Your household, your records
Whoever creates a household owns it and decides who else gets in. Anyone invited can read everything in it, and anyone invited as an adult can add to it and remove what they added. Think before you invite: there is no per-document permission. Every read and every change is written to an audit log that the household owner can see.
Accounts
You sign in with Google. Keep that account secure; anyone who can get into it can get into your records. Do not upload anybody's records without their say-so, or a parent's or guardian's where that applies.
Availability and liability
MedVault is provided as it is, with no warranty. Keep the originals of anything that matters — a discharge summary, an insurance document, a report you may need to show somebody. Treat this as a copy, not the only copy. To the extent the law allows, Greyfeathers is not liable for loss or damage arising from use of MedVault, and in particular not for any decision taken on the basis of what it shows you.
Ending it
Ask us at support@greyfeathers.io and we will delete your household and everything in it. We may suspend an account that is being used to break these terms or the law.
Changes
If these terms change, the version number above changes with them, and the next time you sign in you are accepting the version shown on the sign-in page.
