The short version

No account, no email, no adverts and no tracking cookies. Your progress stays on your device.

What's kept on your device

Your drawings in each lesson, how many times you checked them, the lessons you passed and the name you type on the certificate, in this browser's storage (b3d_progress_v1). It never leaves the device. Clear my progress on Your progress, or clearing the browser's data, removes it.

The language you picked, in a cookie called b3d_lang, for a year, so the site opens in it next time.

Counting visits

Vercel Web Analytics counts pages viewed and where visits come from, without cookies and without anything that identifies you. We use it to see which lessons people finish.
