Permitted use

You may generate, solve, share, and print MosaicProof puzzles for personal, classroom, and commercial activities. You are responsible for how you distribute generated material and for checking whether it suits your audience.

No warranty

The site is provided “as is.” Search limits, browser behavior, or software defects may prevent a seed from generating. The displayed uniqueness badge describes the implemented search under the shown settings; it is not a warranty for a transformed or manually altered puzzle.

Acceptable behavior

Do not interfere with the service, evade security controls, or misrepresent the MosaicProof brand as your own hosted product. Automated use must respect reasonable resource limits.

Changes

Features and these terms may change. The updated date appears above. Continued use after a revision means you accept the current version.
