Privacy Policy

Who runs this site

This site is owned and operated by Jeff Jack. If you have questions about your data or this policy, reach me at jeff@stjack.com.

What I collect and why

First-party analytics

This site runs a lightweight, first-party analytics tracker. It does not use cookies. It stores two values in your browser's localStorage:

• A visitor ID— a random identifier generated in your browser. It never leaves your device in a form that identifies you personally.
• A session ID— reset each visit, used to group page views into a single session.

The tracker records:

• Pages you visit and how far you scroll
• How long you spend reading (engagement time)
• Clicks—internal navigation, outbound links, downloads, and contact-form opens
• Basic device info: screen size, browser, operating system
• Referrer (the page that sent you here)

I use this data to understand what people read, how far they get, and where the site is falling short. That's it.

Vercel Analytics

The site also loads Vercel's built-in analytics. Vercel collects anonymized web vitals (load time, interaction delay, layout shift) and page-view counts. No personal data is sent. See Vercel's privacy policy for specifics.

Contact form

If you use the contact form, I receive whatever you type: name, email, message. That goes to my inbox. I don't add you to a mailing list, sell your info, or share it with third parties.

Fonts

This site loads typefaces from Google Fonts. Google may log your IP address when your browser requests font files. I don't control that request beyond choosing to use the service. See Google's privacy policy.

What I don't collect

• No third-party tracking cookies
• No advertising pixels or retargeting
• No fingerprinting beyond what the browser natively sends
• No cross-site tracking
• No sale of data to anyone, for any reason

How to opt out

The analytics tracker respects your browser's Do Not Track (DNT) and Global Privacy Control (GPC) signals. If either is enabled, no analytics data is sent.

You can also opt out manually. Open your browser's developer console on this site and run:

localStorage.setItem("jeffjck_analytics_opt_out", "1")

To reverse it, remove that key or set its value to "0".

Data retention

Analytics data is stored in a database I control. I don't keep it longer than necessary to understand site performance and readership trends. Contact form submissions stay in my email; I delete them when the conversation is done.

Your rights

If you want to know what data I have about you, want it deleted, or want to correct something—email me at jeff@stjack.com. I'll handle it personally. No ticket system, no 30-day runaround.

Children

This site is not directed at anyone under 13 and I don't knowingly collect data from children.

Changes to this policy

If I change how data is handled, I'll update this page and the effective date at the top. For material changes, I'll note it on the site.
