Yardwatch privacy policy
Yardwatch is my personal, non-commercial project. I use it to keep an eye on the wildlife around my house with my own Google Nest cameras. It is not offered to anyone else, and the only Google account that signs in to it is mine. This page describes what it does with Google data, as required for its Google OAuth client.
What it accesses
With my permission, through the Google Home APIs (scope home.platform.v2), Yardwatch reads my home's device list, device states such as camera battery level and connectivity, and camera event history, including Google's event descriptions and the event video clips.
How I use that data
- To keep a private archive of my cameras' event clips and their metadata, indefinitely, searchable by date, camera and kind of animal.
- To track camera batteries and plan when to recharge them.
- To publish a daily count of animal visits on this site. Only per-day counts per kind of animal are published: no times, no camera names or locations, no descriptions, no video, nothing about people.
I do not use the data for advertising, I do not sell or transfer it to anyone, and I do not use it to train general-purpose AI models.
Where it is stored
Clips and their metadata are kept in my own private Google Cloud project, readable only by me. Credentials are kept in that project's Secret Manager.
People
My cameras also record people: my family, visitors, and people who work at the house. Those clips are kept in the same private archive and are never published. If you visited and want a clip of you deleted, ask me and I will delete it.
Google API Services User Data Policy
Yardwatch's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Revoking access and contact
I can revoke Yardwatch's access at any time from the Google Home app or Google Account permissions. Questions: contact me, Andrew Brook, via GitHub or LinkedIn.
