Privacy Policy

Welcome to Leonard Walujan's website. This Privacy Policy explains how I handle your information when you visit this website.

This website is deployed and hosted using Cloudflare. Cloudflare, as the service provider, may collect and process information about your visit to ensure the security and performance of this website.

To maintain the security and reliability of this website, Cloudflare automatically logs certain data about your visit. This data is typically retained for 24 hours and includes:

• IP address
• ISP location
• Pages visited
• Timestamp of the visit
• User Agent (browser and operating system information)

This information is used solely for security purposes, such as detecting and blocking malicious traffic (DDoS attacks, bots, etc.), and for debugging technical issues.

I use Cloudflare Web Analytics (provided by Cloudflare as the host/CDN) for aggregate traffic and performance. Cloudflare Web Analytics does not use client-side advertising cookies. It is separate from LW Website Analytics described below.

I use LW Website Analytics (self-hosted by me) in addition to Cloudflare Web Analytics. LW Website Analytics is not Cloudflare Web Analytics: it is my own privacy-first visitor analytics app, hosted on Cloudflare Workers at https://cicakberenang.leonardwalujan.eu.org.

The tracker script only loads after you interact with the page (keyboard, scroll, mouse press/move/drag, or touch). Passive page loads alone do not load the tracker or send data.

When tracking runs, it may record:

• Page path and title
• Referrer (if present and external)
• Screen resolution and browser language
• Hostname of this site
• A daily rotating visitor hash derived server-side (IP + user agent + salt + site id) — raw IP is not stored as a visitor id
• Country from the Cloudflare edge (CF-IPCountry) when available

No advertising cookies. No cross-site advertising profiles. You can open public aggregate stats from the Website Stats link in the footer when sharing is enabled.

I do not use Google Analytics or other third-party advertising trackers. Analytics on this site are: (1) Cloudflare Web Analytics (Cloudflare infrastructure), and (2) LW Website Analytics self-hosted on Cloudflare Workers at https://cicakberenang.leonardwalujan.eu.org as described above.

If you have any questions about this Privacy Policy, you can contact me at [email protected].
