Privacy

Cookies and tracking

This website does not set any cookies and does not use analytics, fingerprinting, or third-party tracking. No third-party scripts, fonts, or images are loaded — all assets are self-hosted.

Newsletter data

If you subscribe to the newsletter, the following data is stored in a single SQLite database hosted on Fly.io (region: Frankfurt):

  • First name, last name, and email address — used solely to address and deliver the newsletter.
  • A short-lived 6-digit confirmation code (HMAC-hashed, valid for 24 hours).
  • An opaque unsubscribe token, embedded in every newsletter so you can opt out in one click.
  • Timestamps for create/update/confirm/unsubscribe events.

Confirmation emails are dispatched through Resend (Resend, Inc., USA — operating under the EU-U.S. Data Privacy Framework where applicable). Resend processes the recipient address and message contents only for the purpose of delivering the email.

Logs

Application logs are kept on the hosting platform for operational purposes (debugging, abuse defense). Email addresses are never written to logs in plain text — only a keyed (HMAC-SHA256) 12-character correlation tag that lets the same address correlate across events. The tag is opaque without the server-side secret; a leaked log alone cannot be matched against a candidate email list.

Retention and deletion

Subscriber rows are kept while the subscription is active. Unsubscribed rows are kept long enough to honor the unsubscribe (so a future newsletter respects your choice). To request full deletion of your data, write to contact@rascher.online.

Unsubscribe

Every newsletter mail carries a one-click unsubscribe link (RFC 8058) and a List-Unsubscribe header so mail clients (Gmail, iCloud, Outlook) can offer a native unsubscribe button.

Data subject rights

You have the right to access, rectify, erase, and port your data, and to lodge a complaint with the supervisory authority. Requests: contact@rascher.online.
