Terms of Use

Last updated: 28 August 2026

The Mark tool is provided “as is” without warranty of any kind.

  • Not every camera will scan every colour combination or logo overlay. Test with your phone before you print a batch.
  • You are solely responsible for the payload (others’ WiFi networks, personal data in vCards, destination URLs, and whether that destination is lawful).
  • Do not encode illegal or deceptive content. A QR code is not a licence to phish.
  • We may update the tool at any time. Static codes you already downloaded do not change.
  • This is not a dynamic QR, short-link or analytics service. Availability of those features is not implied.

Operator: Ultimatum. ultaultimatum@gmail.com. See contact. By using Mark you accept these terms.
