Responsible for content (§18 MStV)

VAT

Kleinunternehmer under §19 UStG — no VAT is charged by the operator, and no VAT ID exists. Nothing is sold today, so no VAT arises on anything here.

Payments

Papertrek is free: nothing is for sale, no payment is processed, and your only agreement is with the operator named above. Voluntary tips go through Ko-fi or PayPal under their own terms (see the support page); they buy nothing and are not connected to any account. Should anything ever be sold, the seller would be named here first, and Papertrek would still never receive or store card details.

Contact point under the Digital Services Act

Our single point of contact for users (Art. 12 DSA) and for the authorities of the Member States, the European Commission and the European Board for Digital Services (Art. 11 DSA) is contact@papertrek.app, or the form at papertrek.app/contact. You can write to us in German or English. Content you believe is illegal can be reported at Report content.

Liability for content

We are responsible for our own content on these pages under general law. We make no guarantee that the content is complete or current, and we are not obliged to monitor transmitted or stored third-party information.

Liability for links

Papertrek stores links you add to your own manuscripts, and shows links to DOIs and preprint servers. We have no influence over the content behind them; their respective operators are responsible for it.

Consumer dispute resolution

The EU’s online dispute resolution platform was discontinued on 20 July 2025. We are not obliged, and not willing, to take part in dispute resolution proceedings before a consumer arbitration board.
