Privacy & disclaimer
Only necessary data

This site has no accounts or payments and currently exposes no public comment or private message form. Analytics are used to check whether pages and project links work, not to build personal profiles.

User submissions

The main-site frontend does not load comment forms, message forms, Turnstile or related third-party scripts. The Community service remains as a foundation for future features, but its public write endpoints are disabled.

If interactive features return, this page will be updated with the fields collected, purposes, retention periods and moderation process.

Analytics and click events

Traffic trends are provided by Cloudflare Web Analytics. Anonymous interaction events may record an event name, page path, project target, interface language, device class, timestamp and a random identifier for the current browsing session.

Raw IP addresses, full User-Agent strings, cookies, mouse paths and form contents are not stored.
The session identifier exists only in the current tab session and does not identify visitors across sessions.
Custom click collection is not loaded when Global Privacy Control or Do Not Track is enabled.
Raw interaction events are retained for 90 days; only anonymous aggregates are kept long term.

Security records

Cloudflare handles DDoS, malicious scanning, anomalous requests and bot traffic at the edge. Raw security events are retained by Cloudflare under its platform policies and used only for protection and troubleshooting.

This site's own statistics retain only daily aggregates by site, status class, controlled reason code, region and count. They do not retain malicious request bodies, cookies, full query parameters or raw network addresses.
