This website (samjia12.com) is operated by Sam Jia. This page explains what data is collected and how it is used.
Web analytics
We use Cloudflare Web Analytics to understand basic site traffic such as page views, referrers, and broad usage patterns. This helps improve the site.
Fonts and infrastructure
Web fonts are hosted on this site. Font files are served from samjia12.com rather than a third-party font CDN.
Email subscriptions
If you subscribe, we collect your email address to send new posts and occasional updates. Subscriptions are handled by Buttondown. You can unsubscribe at any time using the link in any email.
Interactive tools
Some playground tools may query third-party map and geocoding providers through our server-side functions in order to render search results, boundaries, and route estimates.
Some tools also store preferences, progress, or local click counts in your browser using local storage. This information stays on your device unless a specific tool clearly states otherwise.
Data sharing
We do not sell your personal data. We may share data with service providers only as necessary to operate this site.
