Privacy

What we collect

When you submit the email-capture form, we collect:

• Your email address (required)
• Your company name (optional)
• Your role or job title (optional)
• A free-text problem description (optional)
• The source page where you submitted the form (e.g. homepage, a specific lesson)
• Standard server data: IP address, timestamp, browser user-agent

We use anonymous aggregate analytics (Vercel Analytics) to understand which pages are read and which links are clicked. Analytics does not collect personally-identifiable information.

How we use it

Your email is used to deliver the PDF you requested and, with your consent, occasional updates about new courses or content. We do not sell, rent, or share your email with third parties.

The optional company / role / problem description fields help us understand who's reading and what to write next. If you provide a problem description, we may use it (anonymized) as inspiration for future lesson topics. We never quote your description publicly without your permission.

Where it goes

Submissions are sent to a private email inbox and, when configured, stored in a database we operate. Both are protected by standard access controls.

Your choices

• Unsubscribe from any future email by replying or using the unsubscribe link in any message.
• Delete your databy contacting us; we'll remove your record from our systems within 30 days.
• Reading the course does not require giving us any data. The full course is publicly readable at this site without any sign-up.
