Privacy

This notebook is a small static site with a small mailing list. It collects the minimum it can and doesn't sell anything.

What is collected

• Your email address, if you subscribe to the newsletter. Stored with the mailing provider and used only to send the notebook.
• Aggregated bounce and delivery info from the mailing provider, used to keep the sender reputation healthy.
• Web server access logs (IP, page, timestamp, user-agent), retained for 30 days, used only for spam / abuse investigation.

What is not collected

• Third-party analytics. No Google Analytics, no Plausible on this site, no Facebook pixel, nothing.
• Advertising cookies. There are no advertising cookies because there are no advertisers.
• Tracking pixels in emails. Every letter is plain text or minimal HTML; there is no open-tracker beacon.

Your controls

Every mailing has a one-click unsubscribe link. To have your address removed from the archive as well, email notes [at] promptlab.pics and it will be deleted within seven days.

Children

This site is not intended for and does not knowingly collect information from children under 16.
