Frequently asked questions

1. Do I need to install anything?

The core course opens directly in a modern browser. Certain exercises require local development tools, and the course provides setup instructions for those exercises.

2. Does it work offline?

Yes. The self-contained HTML course is designed to work offline after downloading and extracting the files.

3. Will my progress be saved?

Progress saves in your browser. It is not a cloud-based account, so browser data clearing or switching devices or browsers may affect your saved progress.

It may open on a mobile browser, but a computer is recommended for the code editor, exercises, and overall learning experience.

5. Can I share the course or use it commercially?

No. The purchase is for personal use only. Redistribution, resale, sharing the files with others, or repackaging the course is not permitted.
