CleanCourse is a website with several courses that you can get with one payment, and keep forever. We have courses for Python, Networking, Kali Linux and more.

• You pay once, and keep it forever. We sell our courses in the form of lifetime ownership and after initial payment, you have no further obligations and you can start learning immediately!
• We offer digital PDF-certificates to quickly show what course you have finished. These are included in the course price, and you don't need to go anywhere or do anything special to get them!
• You stay on one website for the entire course, and your data including progress is private.
