Terms of use of the Qevik confirmation interface
Version 1.0 · Effective October 22, 2026
Translation: only the German version is binding.
1. Subject and parties
These terms govern the free use of Qevik's confirmation interface (the "API") by the operator of the declared domain (the "Platform"). The person declaring the domain states that they act on behalf of its operator and are authorised to bind it. They provide the operator's name, its country of establishment and a contact address, and keep them up to date. The Platform acts for business purposes.
2. Free of charge
Use of the API is free of charge. Neither party owes the other any payment. This creates no right to continued free use.
3. Purpose
The Platform uses a confirmation solely to show, at its user's request, that the user's account on the Platform is linked to a Qevik account. Any other use is excluded. In particular, the Platform must not:
- a) sell, rent or disclose a confirmation, or the information it contains, to any third party;
- b) match a confirmation against other data in order to identify the person behind the Qevik account, or to link Qevik accounts with each other or with accounts on other platforms;
- c) use it for advertising, profiling or rating its users;
- d) make access to its service conditional on presenting a confirmation.
4. Pseudonym
Each time a confirmation is issued or renewed, the Platform transmits as the pseudonym the public name under which the user who gave the authorisation appears in its listings, and no other. It never uses an email address, a phone number or any identifier that is not already public on the Platform.
5. Displaying the badge
The Platform displays a Qevik badge only:
- a) if the user has expressly chosen it, and removes it as soon as the user withdraws that choice;
- b) next to the pseudonym contained in the confirmation;
- c) using the files of the Qevik kit, without modifying them;
- d) in the language of its interface if that is German, French or English, otherwise in the text-free variant or in English; it does not translate or rephrase any wording;
- e) as a link to Qevik's verification page, built as described in the technical documentation, in the language of the badge and carrying the confirmation;
- f) for as long as the confirmation has not expired;
- g) for the wording about labels, only if the confirmation shows it.
The Platform does not combine the badge with any statement suggesting that Qevik verifies the user's identity, vouches for the user or their services, insures items, recommends the Platform or is its partner.
6. Retention
The Platform deletes each confirmation no later than its expiry. It may keep the Platform-specific identifier contained in the confirmation for as long as the user keeps their two accounts linked, and deletes it afterwards.
7. Qevik name and logo
Qevik grants the Platform, free of charge, a non-exclusive, non-transferable right, revocable at any time, to use the kit files solely for the purposes and on the conditions of section 5. Any other use of the Qevik name or logo, in particular in a domain name, a trade mark, advertising or to present itself as a Qevik partner, is excluded.
8. Personal data
Qevik and the Platform are separate controllers. The Platform does not act on Qevik's behalf. It is solely responsible for its own processing of confirmations and pseudonyms, for informing its users, for the legal basis of that processing and for answering their requests. It verifies each confirmation as described in Qevik's technical documentation.
9. Availability, closure and changes
The API is provided without any service level or availability commitment. Qevik may at any time and without notice suspend or close a Platform's access, or discontinue the offer. Confirmations already issued remain verifiable until they expire, unless Qevik shows the closure on its verification page. Qevik may amend these terms; the new version applies to the Platform thirty days after it is sent to the declared contact address. A Platform that rejects it stops using the API.
10. Liability
As the service is free of charge, Qevik is liable only for intent and gross negligence, and for damage where the law prohibits excluding or limiting liability, in particular injury to life, body or health and under the German Product Liability Act. The Platform indemnifies Qevik against third-party claims arising from the Platform's culpable breach of these terms.
11. Governing law and jurisdiction
These terms are governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods. To the extent permitted by law, the courts of Essen have jurisdiction. The German version prevails.
12. Final provisions
If a provision is invalid, the others remain in force. No tolerance constitutes a waiver.
