Privacy Policy

Personal Home Assistant Integrations
Last updated: 13 November 2026

This policy describes how private, non-commercial applications used to connect third-party services to a personal Home Assistant installation access and handle information. These integrations are intended for personal household use, not as a service offered to the public.

1. Services and information accessed

Depending on the integration enabled and permissions granted, the applications may access:

• Google Calendar: calendar names, event dates and times, titles, availability and other event details needed for household reminders and automations.
• Google Nest / Smart Device Management: authorised device information such as thermostat temperature, operating mode, heating status and device controls.
• Other integrations added in future: only the information and device permissions explicitly authorised for that integration and required for the selected home-automation functions.

Access is limited to the permissions authorised through each provider. Adding a new service may require an update to this policy if its data practices materially differ.

2. How information is used

Information is used to display relevant status in Home Assistant and to run personal automations, such as notifying a household member before a meeting or controlling heating based on authorised Nest device settings. It is not used for advertising, profiling for commercial purposes or sale to third parties.

3. Storage and security

Home Assistant may retain integration settings, authentication tokens, entity states, event details and limited historical information on the privately managed Home Assistant system, according to its configuration. Access to the system is restricted by its authentication and security settings. Data is retained only as needed for the integrations and the system's configured history and backups.

4. Sharing and third-party services

Personal information is not sold. The integrations communicate with the relevant service providers (such as Google) to retrieve information or carry out authorised commands. Information may also be handled by infrastructure and service providers used to operate the private Home Assistant system, subject to their respective terms and privacy practices. No public access to private calendar or device information is intended.

5. Google API data

Information received from Google APIs is used only for the home-automation functionality described here and in accordance with applicable Google API Services User Data Policy requirements. It is not transferred to advertising platforms or data brokers.

6. Your choices and deletion

Permissions can be revoked at any time through Google Account connections or the relevant provider's account controls. Integrations can also be removed from Home Assistant. To remove locally retained data, delete the relevant integration and any associated history or backups as appropriate for the Home Assistant configuration.

7. Changes to this policy

This page may be updated when new integrations are added or when the handling of information changes. The date above will be revised when the policy is updated.

8. Contact

For questions about these private integrations or this policy, contact the operator of the Home Assistant installation through the website hosting this page.
