Privacy Policy

Last Updated: November 11, 2026

      Summary: Home Automation Hub is a private, self-hosted home automation system. We do not sell, rent, monetize, or share your personal data with third parties. Google Assistant integration is utilized solely to execute your private, scheduled home automation commands across your smart home devices.
    

1. Information We Collect and Access

Home Automation Hub operates under a privacy-first model:

Google User Data: When authenticated via Google OAuth with the assistant-sdk-prototype scope, the application only accesses the Google Assistant API to transmit user-defined automation text instructions (e.g., "turn on mini", "turn off mon1") and receive the execution status from the Google Assistant service.
Account Details: We do not collect or store your Google account profile information, search queries, emails, files, or contacts.
Device Telemetry: Device state information (such as online status or light brightness) is stored exclusively on your local, self-hosted hardware and is never sent to external servers.

2. How We Use Information

All data accessed through Google APIs is used exclusively to provide the core functionality of Home Automation Hub:

Translating scheduled automation events (such as wake-up routines or bedtime sequences) into smart device commands.
Monitoring the health and connectivity of local hardware peripherals.

We do not use Google user data for advertising, marketing, analytics, profiling, or machine learning model training.

3. Information Sharing and Disclosure

Home Automation Hub does not sell, transfer, or disclose any Google user data or personal information to third parties. Data exchange is strictly limited to direct, encrypted communication between your local self-hosted instance and the official Google API endpoints necessary to execute user commands.

4. Data Retention and Deletion

OAuth authentication tokens are stored securely and locally on the user's host system.
Tokens are retained only as long as the integration remains active.
Users can revoke access at any time through their Google Account Security Settings or by removing the Google Assistant SDK integration from their Home Assistant instance, which permanently deletes all stored credentials.

5. Security of Your Information

We implement industry-standard security measures to safeguard your credentials. All communications with Google APIs are encrypted using Transport Layer Security (TLS/HTTPS). OAuth tokens and cryptographic secrets are stored within restricted system directories with limited access permissions.

6. Compliance with Google API Services User Data Policy

Home Automation Hub's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
