Privacy at zHealth

Updated 28 September 2026

The planned oral-health app

zLock is the name of our planned system for encrypting stored health data in the native zHealth app. At launch, the app is intended to let you choose whether zAI can use your data and delete your stored health records. These protections are in development and must be verified in the release build. They are not a claim that the current test build is fully encrypted or that any service can guarantee absolute security.

Choosing to share information with zAI will involve processing by our AI service providers. The app’s release privacy notice will explain the data, purpose, retention and deletion limits before you give consent. zLock does not mean that an AI answer is generated without providers processing the information you choose to send.

Newsletter privacy

zHealth, founded by Zak, uses your email address to confirm your signup and share occasional updates about the oral-care app and its release. We send these messages only when you opt in. You can withdraw that consent at any time by emailing zHealth.official@gmail.com.

Your phone number is optional. If you provide it and separately tick the phone-storage box, we encrypt and save it for a possible later text rollout. We do not send texts on the basis of this form. We will ask for separate SMS consent first.

The newsletter list, consent record, and encrypted optional number are held in our Cloudflare-hosted database. Resend processes your email address to deliver confirmation and update messages. We do not sell your details. We keep the email address while you remain subscribed and review inactive records at least annually. We will review optional numbers within 90 days and erase them if no text programme is launched. Limited abuse-prevention records are short-lived.

You can ask to access, correct, or erase your details, or withdraw consent, using the email above. You can also complain to the UK Information Commissioner’s Office. Email and phone are not required to browse this site; email is required only if you choose to join the list.
