Frequently asked questions
How long do I have access to a course?
Courses are a one-time purchase with lifetime access — no subscription, no expiration.
Do I get a certificate?
Not yet — certificates are on our roadmap but not available in the current version.
What if I want a refund?
Reach out via the Contact page within 14 days of purchase and we’ll take care of it.
Do courses assume prior knowledge?
Each course description lists prerequisites. Courses build from first principles wherever possible.
Can I access lessons offline?
Not currently — lessons stream from the platform and require an internet connection.
