Key definitions
Personal data: Any information that could identify you directly or indirectly, including names, identifiers, location data, online identifiers (like cookies), or characteristics that reveal your identity.
Processing: Any operation we perform on personal data, whether automated or manual, including collection, storage, use, or deletion.
Pseudonymisation: A privacy technique where we separate your personal data from direct identifiers, making it impossible to identify you without additional information that we keep strictly separated and secured.

Data Controller: The entity that determines how and why personal data is processed - in this case, Johannes Filter.
Server logs and security
For security and stability purposes, our hosting infrastructure automatically records basic information about each visit to our site. This includes:
- Which pages were accessed and when
- Technical details like browser version and operating system
- Data transfer volumes and success status
- Referring websites
- Anonymized network information
These logs help us detect and prevent security threats. We retain them for up to 7 days, except when needed for investigating security incidents. This processing is based on our legitimate interest in maintaining a secure and stable website (Article 6(1)(f) GDPR).
Analytics with Matomo
We use Matomo, a privacy-friendly analytics platform that we host ourselves. Unlike commercial analytics services, your data never leaves our servers. Matomo helps us understand:
- Browser types and operating systems our visitors use
- Geographic regions (country-level only)
- Visit patterns and duration
- Which external links are clicked
Importantly, we anonymize IP addresses before any storage occurs, ensuring your privacy is protected. This processing serves our legitimate interest in understanding and improving our website (Article 6(1)(f) GDPR).
Matomo places small text files (cookies) on your device to recognize return visits. These cookies:
- Expire after one week
- Create only pseudonymous usage patterns
- Store data exclusively on our servers
- Are never shared with or sold to third parties
You can disable these cookies in your browser settings without affecting your ability to use our site.
You have full control over analytics tracking. Click the link below to opt out of Matomo analytics. This sets an opt-out cookie that tells Matomo to ignore your visits. Note that if you clear your browser cookies, you’ll need to opt out again.
All analytics data is automatically deleted after 6 months.
