Hearth privacy policy

Last updated 28 October 2026

Hearth controls the smart-home devices in your own home through a hub you run yourself. It is built to keep your home's data in your home.

What stays on your hub

Your devices, rooms, readings, activity history, automations, energy use and notification settings are stored on your own hub, not on our servers. The app talks to your hub directly over an encrypted connection; our servers only help your phone find it.

Your Hearth account

If you create an account we keep your name, email address, a hashed password or your Sign in with Apple identifier, and any passkeys you add. We use them only to sign you in and to let you choose which hubs you can open. We never sell or share them.

Location

If you turn on Arrive & leave, your iPhone works out on the device whether you are at home. Only "home" or "away" is sent to your hub. Your location itself never leaves your phone.

Notifications

Your hub keeps your phone's push token so it can send you notifications through Apple Push Notification service.

Crash reports

If the app crashes, Apple's diagnostic report (no personal content) is sent to your own hub to help fix the problem.

No tracking

Hearth has no adverts, no analytics and no third-party tracking.

Deleting your data

You can delete your account at any time in the app under Account → Delete account. This removes your account, passkeys and sign-in sessions from our servers straight away. Data on your hub is yours to keep or remove.
