This site uses a minimal, self-hosted analytics system to understand how the content is being used. Here's exactly what that means.

What we collect

• Page paths — which pages you visit (e.g., /certs/aws/saa-c03/)
• Referrer — how you arrived (e.g., from a search engine or direct link)
• Time on page — how long you spend reading each page
• Random visitor ID — a randomly generated identifier stored in your browser's localStorage to distinguish unique visitors

What we don't collect

• IP addresses — not logged or stored
• Cookies — we don't use cookies at all
• Personal information — no names, emails, or account data
• Device fingerprinting — no browser or device identification
• Cross-site tracking — your visitor ID is unique to this site only

Where data is stored

All analytics data is stored in a DynamoDB table in my AWS account. No third-party analytics services are used. Raw pageview events are automatically deleted after 90 days.

Why we collect this

The data helps me understand:

• Which study guides are most useful
• Whether visitors return (indicating the content was helpful)
• How long people spend reading (to gauge content quality)

How to opt out

The toggle above sets a flag in your browser's localStorage that the analytics script checks before sending anything. It applies to this browser only. Other options:

• Clear localStorage — your browser's developer tools can clear the ptn_visitor_id key
• Use private/incognito mode — localStorage is cleared when the session ends
• Browser extensions — content blockers like uBlock Origin will block the analytics script
• Disable JavaScript — the site works without JavaScript; only analytics requires it
