Privacy Policy

Last updated: February 15, 2026

TL;DR: Privacy is a fundamental human right. I respect yours completely. This site uses Cloudflare Web Analytics (privacy-first, no cookies, no personal data tracking). I don't collect, store, or sell your personal information. That's it.

What Data I Collect

This website uses Cloudflare Web Analytics, a privacy-first analytics service that does not:

Use cookies
Track you across websites
Collect personally identifiable information
Fingerprint your device
Store your IP address

Cloudflare Web Analytics only collects anonymous, aggregated metrics like:

Page views
General location (country/region level only)
Referring sites
Browser and device type

Why I Collect Data

I use analytics to understand:

Which content resonates with visitors
How people find my site
Basic performance metrics

This helps me improve the site and create better content about data and information design, and exploring.

Theme Preference Storage

If you toggle between light and dark mode, your preference is saved in your browser's localStorage. This data:

Never leaves your device
Is not sent to any server
Can be cleared by clearing your browser data

Third-Party Links

This site contains links to external websites (LinkedIn, Twitter, Rivian). I'm not responsible for the privacy practices of these sites. Please review their privacy policies.

Your Rights

Since I don't collect personal data, there's nothing to request, delete, or export. You're already in full control.

Data Retention

Cloudflare Web Analytics retains anonymous, aggregated data for analytical purposes. No personally identifiable information is retained. Theme preferences stored in localStorage remain on your device until you clear browser data.
