What data we process

Listings: serial code, currency, denomination, the link you provide to your listing on an external platform, and a contact email address. No account is required for this – listings can be created anonymously.
Edit link: if a listing is created without an account, we generate a random, secret edit token that lets you change or remove it later. It's shown to you once as part of a link; we never send it by email.
Account (optional): if you register, you provide an email address and a hashed password, so you can find your own listings together under "My listings".
Session: a technically necessary session cookie keeps you logged in and protects forms via a CSRF token.
Language setting: your choice between German and English is stored in a cookie.
Theme setting: your choice between light and dark mode is stored in your browser's localStorage, not on our servers.

No trading on this site

This site is a pure link collection. The actual purchase or sale of a bill happens exclusively on the respective linked external platform. We do not process any payment, shipping, or contact data between buyer and seller, because no such transaction takes place through us.

Purpose and legal basis

Processing takes place to fulfill the usage agreement (Art. 6(1)(b) GDPR) – i.e. to enable creating and managing listings in the first place – as well as to safeguard legitimate interests in the secure operation of the site (Art. 6(1)(f) GDPR).

Recipients

We do not share data with third parties unless legally required to do so. If you click a link to an external listing, that provider's own privacy policy applies there.

Retention period

Account data remains stored until you have your account deleted. Anonymously created listings remain stored unless removed via the edit link or by us.

Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR), as well as the right to lodge a complaint with a data protection supervisory authority. Please contact: ….
