# Data Collected

This website does not actively collect personal data. When you visit, the hosting provider (itsh.dev) records standard server log data: IP address, date/time, requested URL, browser type, and referrer. These logs are used for system security only and are not combined with other data. In addition, cookieless reach measurement runs on a self-hosted OpenPanel instance; details in the following section.

# No Cookies

This website sets no cookies and uses no tracking pixels. Reach measurement is handled by a self-hosted OpenPanel instance running on own infrastructure (op.nachtigall.dev). The measurement works without cookies: instead of storing IP addresses, a daily-rotating, irreversible hash of IP address, browser signature, and project ID is generated for at most 24 hours to distinguish visitors. Stored per event: the page path, referrer, browser, operating system, and device type information, plus details such as the language version of the visited page. Raw IP addresses are never stored. No names or email addresses are collected, no user profiles are built, and no cross-site tracking is performed.

# No Third-Party Services

Fonts and icons are served locally. No data is transferred to Google Fonts, CDN providers, or any other external services. Reach measurement runs entirely on own infrastructure; no data is transferred to third parties.

# Your Rights

Under GDPR you have the right to access, rectification, erasure, restriction of processing, and data portability. You may also lodge a complaint with the relevant supervisory authority. Contact for data requests: contact@nachtigall.dev
