Two ways to do it. The first takes about ten seconds.
It happens immediately. There is no waiting period and no "are you sure" email to click.
A contact address for deletion requests is not published yet. It is being set up on the app's own domain, and this page will carry it as soon as it exists.
Until then, the in-app route above is the way to delete an account. If you have already uninstalled the app, reinstalling it and signing in restores access to the delete button — your account is still there, and none of your health records were ever on our server to begin with.
Your health records — dates, readings, vaccinations, kick counts, photos, appointments — are on your phone and were never sent to us. Deleting your account does not touch them and cannot.
To remove those, uninstall the app (or use Settings → Start over inside it). And if you want to keep them, export the PDF first — once the app is gone they cannot be recovered by us or by anyone.
If you have a paid subscription, deleting your account here does not cancel the billing. Subscriptions are held by Google Play and only Google can stop them. Cancel it in the Play Store — Play Store → your profile → Payments and subscriptions → Subscriptions — otherwise it will keep renewing after your account is gone.
Questions about any of this: use the help button in the app, or see the privacy policy.
