It might be interesting to someone that GitLab is not seem to be compliant with current European data regulations (GDPR), it is worth reading their terms and privacy statements [1][2]. E.g. even self hosted GitLab phones home in opt-out fashion.

GitLab collects information about usage from each self-hosted GitLab instance (Community Edition and Enterprise Edition) through a usage ping. The usage ping sends a payload containing data such as total number of projects and pipelines, as well as license information and hostname to GitLab.

...

The information from the usage ping is not anonymous, it is linked to the hostname of the instance [3]

...

The documentation is a merge request [4]

This MR loads the EE usage ping asynchronously on the admin application settings page and now includes the counts of the following items:
