Website terms

Last updated 21 October 2026. These terms cover this website and its waitlist. Using the Previa Family app is covered by separate Terms of Service, shown before you create an account.

About this site

previafamily.com is run by Previa Family, Inc. (in formation). Its incorporation in Delaware is being completed; until then, its founder, Yash Jain, runs the site on its behalf. It describes the Previa Family app and lets you join the waitlist.

Not medical advice

Nothing on this website is medical advice. Previa explains health reports in plain language with sources; it doesn't diagnose or treat, and it never replaces your doctor. In an emergency, call your local emergency number.

Examples and demos

The people, families, reports, numbers and Kahu answers shown on this site are made up to show how the app works. They are not real people or real health data. The Kahu demo is scripted; it is not a live AI.

The waitlist and the launch offer

• Joining the waitlist is free. Please sign up with an email address that's yours.
• The launch month is early access for waitlist members, and it's free, with every feature. Waitlist members who start within 60 days of their launch invitation get at least 30 days free from the day they start. A month after launch, plans begin, and everyone gets 2 weeks free first. One free period per person and per family. Nothing is charged unless you choose a plan.
• We handle your waitlist details as described in the waitlist privacy notice.

Using the site

Please don't misuse the site: no automated sign-ups, no attempts to break its security, and no use that breaks the law. We may block access that does. To report a security issue, see Security.

Our content

The text, logo, code and design of this site belong to Previa Family, Inc. (in formation). You're welcome to share links to it. Please don't copy the logo, illustrations or app designs without asking. Previa Family™, Kahu™ and Living Tree™ are trademarks of Previa Family, Inc.

Links to other sites

Some pages link to public health sources such as MedlinePlus, the NHS and the World Health Organization. We don't control those sites and aren't responsible for their content.

No warranty

We work to keep the site accurate and available, but it's provided as it is. To the extent the law allows, we're not liable for losses that come from using it. Nothing here limits rights you have under consumer law where you live.
