Privacy

Anonymous measurement, only with your permission.

This portfolio asks before measuring anonymous interactions. The data is used only to improve clarity, accessibility, and navigation.

What measurement includes

  • Consented visits and repeat visits, distinguished by a random identifier stored in your browser.
  • Section visibility, approximate attention time, scroll depth, and navigation or contact interactions.
  • Possible usability friction, such as repeated actions, non-action clicks, and navigation loops.
  • Broad device category, viewport range, language, timezone, referral domain, and optional campaign labels.
  • Anonymous recommendations for published portfolio projects.

What is not collected

  • No name, email address, phone number, account profile, or text you type.
  • No cursor recording, session replay, keystrokes, click coordinates, or form contents.
  • No application-level storage of IP addresses and no precise location.
  • No advertising profile, cross-site tracking, sale, or commercial sharing of analytics data.

Purpose and access

I review aggregated metrics in a private owner dashboard. They help identify unclear information hierarchy, interaction friction, and mobile drop-off.
