Terms of Service

Effective 10 November 2026

These terms cover a private, self-hosted Home Assistant installation and its Google Assistant SDK integration ("the application"). By using the application, the household owner agrees to them.

1. Personal, non-commercial use only

The application is operated for the private, non-commercial convenience of one household. It is not sold, licensed, distributed, published to any app store, or offered as a service to any third party. No one outside the owning household is authorised to use it.

2. No account, no service level

There is no registration, no support commitment, and no availability guarantee. The application runs on hardware the owner controls and may be modified, suspended, or switched off at any time, without notice, including permanently.

3. Provided "as is", without warranty

The application is provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. No warranty is given that it will be uninterrupted, timely, secure, or error-free.

4. Limitation of liability

To the fullest extent permitted by law, the owner shall not be liable for any indirect, incidental, special, consequential, or punitive damages, nor for any loss of data, property damage, or any consequence of a device failing to respond to a command. This includes physical devices controlled through the integration — light switches, lights, and similar household equipment — which may fail, act late, or act without being asked. The owner's total liability in any matter arising from these terms is limited to the amount paid for the application, which is zero.

5. Third-party services

The application depends on Google's Assistant API and on the household's Google account. Google's terms and policies govern that relationship, and Google may change or withdraw its APIs at any time. The application also depends on the open-source Home Assistant project and on the local network and hardware it runs on. Nothing in these terms grants any rights in third-party software or services.

6. Acceptable use

The application must be used only for lawful household automation. It must not be used to access accounts the owner does not control, to circumvent any access control, or in violation of Google's terms of service or applicable law.

7. Privacy

Data handling is described in the privacy policy, which forms part of these terms.

8. Changes

These terms may be revised; the current version is always the one published on this page, with its effective date.

9. Governing law

These terms are governed by the laws of the State of residence of the household owner, in the United States, without regard to conflict-of-law rules.
