The short, plain version for beta.
Who this is for
The beta is open to adults 18 and older in the US and Canada.
Not medical advice
Cyster is for education only. It doesn’t diagnose, treat, or replace care from a qualified clinician. Talk to your clinician about your own health.
It’s a beta
Cyster is early and still changing. Features may shift, break, or be removed as we build.
Using it fairly
Use Cyster for your own personal, non-commercial use, and don’t try to misuse or abuse the service.
