How can we help?

Cohort is in a private beta that started in Austin. Join the waitlist and we'll email you an invite as spots open — invites go out in batches, so it may take a little while after you sign up.

Cohort connects the health and activity apps you already use, matches you with a small cohort of people genuinely like you, and shows what actually moves your numbers — measured against real variation inside your group, not population averages.

No. Connect sources you already have — Apple Health, Android Health Connect, Strava and others. Blood panels and DEXA scans add more detail if you have them, but they're optional, never required.

Yes. Your health measurements are end-to-end encrypted on your device with keys that never reach our servers — we store only ciphertext and cannot read them. The full detail is in the Privacy Policy.

In the app, open Settings and manage your connected sources there. Every connection is read-only, and you can revoke any one of them at any time.

In the app: Settings → Privacy. Or email hello@cohort.health. Deletion removes your data from our active systems; the Privacy Policy covers the full retention detail and the honest limits (published aggregates can't be unpublished).

Yes — one login works across all three apps.

Your passphrase is what encrypts your data, and it never reaches our servers — so we genuinely can't read it or reset it for you. If you're locked out or something looks wrong, email hello@cohort.health and we'll help you sort out access.

First make sure you're on the latest version, then try disconnecting and reconnecting the source that looks wrong. If it still isn't right, email hello@cohort.health with your device model and app version and we'll dig in.
