PRIVACY
A small site, a small footprint.
A static notebook, with no accounts, advertising, or comment tracking.
Your preferences
An explicit language or colour-theme choice is saved in this site’s local browser storage. It is not sent to a server. Clearing site data removes it.
Practice and Python
Practice storage is off by default. If you choose to remember practice, answers, progress, working notes, and Python code are saved only in this browser. You can clear practice data separately from language and theme preferences. Python is loaded from this site when you run an exercise; your code and answers are not uploaded. Public tests provide feedback for self-study.
