You can delete your I'm Home account and its data from here, or from inside the app. Neither requires contacting anyone.
Delete it here, right now
Sign in at the web app and delete from Settings — no install needed.
Go to SettingsOpen I'm Home on your phone → Settings → Delete my account → type DELETE to confirm.
Your account and data are removed immediately and cannot be undone. Encrypted backups clear within 30 days. Your family is not notified — the button you gave them simply stops appearing. If you own a circle (you're the one others check in with), that circle and everyone's membership in it go too. If you're a member of someone else's circle, you're just removed from it — their check-in history stays theirs.
Email imhome-support@together-ledger.com from the address on the account and we'll remove it by hand.
