Transparency is at the core of our values. Here's how we handle your data.
Last Updated: February 2, 2026
We collect basic information required to provide our service, primarily your GitHub profile processing information when you authenticate. We do not sell your data to third parties.
DockerHOL is designed for ephemeral learning. Data created inside lab sessions (containers, volumes, networks) is automatically destroyed when the session ends or after the inactivity timeout period. We do not retain persistent copies of your lab work.
We use privacy-focused analytics to understand how our platform is used and to improve the curriculum. This data is aggregated and anonymized.
