No cameras, no microphones. Just a few small sensors that notice movement.
A mark each time a room is used, and when the front door opens. No images, no sound.
It tells the hub which room, and when. It can't record anything else.
It only ever calls out, with its own security certificate. Nothing on the internet can reach in.
Hearth works it out on servers in the EU, encrypted while stored, and shows it only to the family you invite.
The account holder invites family by email, and can remove anyone at any time. Hearth staff have no routine access, and if we ever need to reach the hub to help, it's logged.
When you set Hearth up, we ask you to confirm you've told them what it does, and to record that they agreed, or that you're deciding in their best interests. Everyone in the care circle can see that record.
Each evening an AI model writes up the day in plain English. It's on from the start, and one switch in Settings turns it off. The model's provider is contracted not to learn from it.

Hearth is a wellbeing monitoring system that uses passive sensors: motion detectors and a door contact sensor. There are no cameras, no microphones, and no audio recording of any kind. We believe care monitoring should be invisible to the person being cared for, and transparent to the family using it.
No personally identifiable information is collected from the sensors themselves. The sensors detect activity patterns, not identity.
Hearth is a cloud-first service. A small hub in the home forwards sensor signals, encrypted in transit (TLS with a per-device certificate), to Hearth's cloud infrastructure hosted in the EU, where activity patterns are analysed and made available to your Care Circle through the app and dashboard. Sensor data consists of movement and door events only, never images or audio. Data is encrypted in transit and at rest. The hub only ever makes outbound connections and does not accept any inbound connections from the internet. Access to the dashboard requires a signed-in account.
We use a small number of specialist providers to run the service: cloud hosting, sign-in, transactional email, payment processing and, when AI summaries are switched on, an AI model provider. Each processes only what it needs to do its job. We never sell your data and never use it for advertising.
The written daily updates and weekly report are generated by a third-party AI model provider. AI summaries are switched on when your household is set up, so the app is useful from the first day, and can be switched off at any time in Settings. To generate a summary, aggregated daily metrics (such as room-visit counts, wake and sleep times, outing durations and activity trends) and the display name you have given the monitored person in the app are sent securely over HTTPS to the provider. Raw sensor events and addresses are never sent. The provider is contracted not to use this data to train its models.
Only invited members of the Care Circle can view dashboard data and receive notifications. Care Circle membership is managed by the primary account holder. Members can be added or removed at any time. Hearth Systems staff do not have routine access to your sensor data. Any remote access to the hub for troubleshooting is recorded in an access log, which we will provide to the account holder on request.
Hearth Systems Ltd is the data controller. The data subject is the monitored person (your parent). Our lawful basis for processing is the legitimate interest of the family members in monitoring the wellbeing of a vulnerable person, combined with the informed consent of the monitored person.
As a data subject, the monitored person has the right to:
When a household is set up, we ask the account holder to confirm that they have told the monitored person what Hearth does, and to record one of two things: that the monitored person agreed, or that they are unable to make that decision themselves and the account holder is acting in their best interests. That confirmation is stored with the account, and the account holder can review or change it at any time from Settings.
To exercise any of these rights, contact [email protected].
Hearth is designed for monitoring elderly adults living independently. It is not designed for, marketed to, or intended for use with children under 18.
We will notify all account holders by email of any material changes to this policy before they take effect.
