Account and sign in
Do I need an account?
Not to look around. Zyva opens with example data of a fictional person, marked on every screen. You need an account to keep your own reports or supplements, or to ask about your own values.
How do I sign in?
Enter your email address and open the link we send you on the phone where Zyva is installed. A password is optional.
The link does not arrive.
Check your spam folder. After 60 seconds you can send a new link. A link works once and for 24 hours.
Health Vault
What is the Health Vault?
On your first sign in, Zyva creates a vault key on your phone. The app locks with Face ID, Touch ID, your fingerprint or a code.
I have a new phone.
Sign in and restore your vault with Cloud Backup, if you turned it on, or with your recovery phrase of 12 words. Write the phrase down while you still have your old phone.
I forgot my code.
On the lock screen, tap Forgot passcode. You are signed out and can open your vault again with Cloud Backup or your recovery phrase.
Lab reports
Which reports work?
Lab reports from Germany, Austria and Switzerland as a PDF or a photo. German and English reports work best. Layouts differ between labs, so not every report is read completely.
A value was read wrongly or is missing.
Compare the values with your printed report. If something is wrong, upload the PDF instead of a photo, or write to us without health details in the message.
Tips for photos:
- Lay the page flat on a dark, plain surface.
- Use even light: no flash, no shadows.
- Fit the whole page, straight from above.
- One page per photo.
Supplements
The product is not found.
Our catalogue does not know every product sold in Germany, Austria and Switzerland yet. Photograph the label: first the front, then the ingredient list. This needs an account.
What does the score mean?
A product score from 0 to 10 for ingredients, doses, quality, value and safety. Your lab results are not part of it. It is not advice to take or stop a product. See how we score.
Ask Zyva
What does Ask Zyva do?
Ask Zyva is an AI assistant. It explains the values in your report in everyday language and shows which values its answer is based on.
What does it not do?
It does not diagnose, does not suggest doses and does not recommend treatments or products. AI answers can contain mistakes, so check important values in your original report and talk to your doctor.
Your account and data
How do I delete my account?
Delete your account explains the steps, with and without the app.
Can I get a copy of my data?
Yes. In the app, go to Settings, Export my data. You get your health data as a FHIR file.
