Who we are
This site is operated by Konrad Reyhe. If you have questions about your data, contact me at kreyhe@yahoo.com.
Analytics
We use self-hosted Plausible CE for anonymous usage statistics. Plausible is privacy-friendly by design:
- No cookies
- No personal data collected
- No cross-site tracking
- No fingerprinting
- All data stays on our own server (Hetzner, Germany)
Plausible collects page views, referrer, country, device type, and browser. None of this is personally identifiable. Read Plausible's data policy.
Newsletter
If you sign up for our newsletter, we collect your email address only. The newsletter is managed by Buttondown. You can unsubscribe at any time using the link in every email. We never share your email with third parties.
Payments
Ebook purchases are processed by Stripe. We never see or store your payment details. Stripe handles all payment data under their own privacy policy.
Cookies
This site uses no cookies. Theme preference and tool data are stored in your browser's localStorage and never sent to any server.
Your rights
Under GDPR, you have the right to access, correct, or delete any personal data we hold. Since we only store newsletter emails (if you subscribed), you can:
- Unsubscribe from the newsletter at any time
- Request deletion of your email by contacting kreyhe@yahoo.com
Hosting
This site is hosted on a Hetzner server in Germany. All data processing occurs within the EU.
