The NOISK.AI reference library contains images sourced from public domain and open-licence datasets. Each image carries one of the licences listed below. When you use a reference image in your workflows, you must comply with its licence terms.
This document is a draft pending legal review.
No licence completely waives moral rights, personality rights, privacy rights, or other rights that people may hold in a work or in how it is used. This matters most for images depicting identifiable people. See the Acceptable Use Policy for your obligations around images of real people.
In plain language: No rights reserved. Use for any purpose, commercially or non-commercially, without attribution.
Requirements: None.
Official text: creativecommons.org/publicdomain/zero/1.0/
In plain language: Copyright has expired, was never held, or was explicitly abandoned. Free to use for any purpose, with no conditions.
Requirements: None with respect to copyright.
Note: Public domain status can vary by country — a work in the public domain in the United States may still be protected elsewhere. If you are publishing internationally and have concerns, consult a qualified lawyer.
In plain language: An institution (museum, library or archive) has identified this work as free of known copyright restrictions worldwide. Same practical effect as Public Domain above.
