Privacy policy.

Data we collect

We collect your email address when you request a free component or subscribe, together with the data needed for billing when you buy.

How we use it

Your email address is used to send you the content you asked for and our updates about the course. You can unsubscribe in one click from every email.

Processors

Your data passes through three processors: Stripe (payment), Cloudflare (hosting for the platform and the database) and Vercel (hosting for this site). Each of them handles it under its own privacy policy.

Retention and your rights

Under the GDPR, you have the right to access, rectify and erase your personal data.

Cookies

The site does not use advertising cookies. Fonts are served locally from the site: no data is sent to Google.

Audience measurement

The member area uses PostHog to measure how the course is used — pages opened, lessons completed, where people get stuck. The data is hosted in the European Union and is never sold or shared with advertisers. Events are tied to an account identifier, never to an email address, and form fields are masked before anything is recorded. You can switch this measurement off at any time from your browser console with posthog.opt_out_capturing(), or by asking us.
