Thelen Lab

Privacy policy

Last updated 14 September 2026.

Thelen Lab is a private home lab operated by one person for their own use. The only Google account whose data it ever touches is the operator's own. There are no other users, no customers, and no third parties.

This policy is a statement of fact about a single-operator system, not a template. It describes precisely what the lab's Google API clients do.

What is accessed, and why

Signing in (OpenID Connect)

Several self-hosted applications in the lab use Sign in with Google rather than keeping their own passwords. When the operator signs in, each application receives and stores three things in its own local database:

That is the whole of it. No other profile fields are requested, and this data is not shared with anyone.

Google Drive

The lab runs rclone to keep a personal Obsidian notes vault synchronised, in both directions, between a disk in the rack and a folder in the operator's own Google Drive. This uses the Google Drive API under the drive scope.

The files involved are the operator's own notes. They are copied between the operator's own Drive and the operator's own hardware, and nowhere else. They are not read by any person other than the operator, not sent to any third party, not used to train any model, and not processed by any service outside the lab.

Where the data lives

On self-hosted hardware in a private residence, backed up to storage controlled by the same operator. Access to the applications is restricted to the home network and an explicit allow-list of one email address.

OAuth tokens are held as secrets on that cluster and are never committed to source control.

What never happens

Limited Use

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

Retention and removal

Sign-in details persist for as long as the corresponding account exists in a given application, and are deleted when that account is deleted. Synchronised notes persist until the operator deletes them.

Access granted to these clients can be withdrawn at any time from Google Account permissions. Doing so stops all further access immediately.

Changes

If what the lab does with Google data changes, this page changes with it, and the date at the top moves.
