Privacy
Short version: no ads, no selling data, and only the analytics you agree to.
When you sign up for the newsletter or a free PDF, we store your email address, the date you agreed, and which PDF you asked for. We use it only to send what you signed up for. Every email has an unsubscribe link, and you can ask for your data to be deleted at any time.
Analytics
If you accept the cookie banner, Google Analytics counts page views so we know which topics help most. If you decline, no analytics script is loaded. You can change your choice from the link in the footer.
Videos
YouTube videos are not loaded until you press play. Until then, no request goes to YouTube. Once you play a video, YouTube's own privacy policy applies.
Accounts
If you sign in with Google or an email link, we store your name, email and sign-in date so you can download PDFs in one click and, later, access courses.
