Terms of use · Open CKey

Last updated 5 November 2026.

Acceptable use

Do not use openckey.org to publish or link to:

phishing, credential harvesting, or impersonation of a person or organisation;
malware, unwanted software, or exploit delivery;
content or destinations that are illegal where you or your readers are;
spam, or links that hide where they lead in order to mislead;
harassment, or private information about someone published without their consent.

Do not try to bypass the verification, rate limits, or safety scan.

Revocation

An administrator can disable any record at any time, for example after an abuse report or a later safety finding, without notice. Disabled records return an error and cannot be reactivated. Short queries also stay inactive unless their automated safety scan clears.

Records and identifiers

Records cannot be edited. To change text or a destination, create a new record.
Identifiers are never reused, even after expiry, revocation, or retirement. A printed code will never start pointing at someone else’s content.
Records retire after 24 months; the text or destination is then removed.

No guarantee

The service is provided as is, free of charge, with no guarantee of availability, durability, or fitness for any purpose. A clean safety scan lowers risk but does not guarantee that a destination is or stays safe: sites change after they are scanned. Do not rely on openckey.org as the only route to anything important, and test printed codes before you distribute them.

Software and licences

CKey — the specification, core, and SDKs — is open source under the MIT licence. This website and its service code are proprietary; all rights are reserved.
