Privacy Policy

This Privacy Policy explains how Zettelkasten ("we", "us", "our") handles information when you visit zettelkasten.online (the "Site"). This Site is a marketing and information website for the Zettelkasten / Mind Dump project.

Who we are

What we collect

Information you provide

If you use our contact form, we receive the information you submit (such as your name, email address, and message). That data is sent to a third-party form relay service (FormSubmit.co) so it can be delivered to us by email. We use this information only to respond to your enquiry.

Analytics (with your consent)

If you accept analytics cookies, we use Visitor Tracking (VisitorTracking.com) to understand how the Site is used. This may include:

• Pages viewed and general browsing activity
• Referring website or campaign source
• Approximate geolocation derived from IP address
• Browser, device, and operating system information
• Session and interaction data (such as clicks and scroll behaviour)

Visitor Tracking describes its service as cookieless, but it may store identifiers in your browser's local storage to maintain session continuity. Analytics does not run unless you choose "Accept all" in our cookie banner.

Strictly necessary storage

We store your cookie preference in your browser's local storage so we do not ask you on every visit. This storage is essential to honour your choice and does not require separate consent.

• GitHub Pages — the Site is hosted as static files. GitHub may process server logs (including IP addresses) as part of hosting infrastructure.

• Consent — for optional analytics tracking.
• Legitimate interests — to operate, secure, and improve the Site, and to respond to enquiries you send us.

How long we keep information
