Commercial Disclosure

Last updated: 7 September 2026

This Company Site

BrianHamilton.xyz identifies the company, introduces the people behind the work, links to our puzzle projects and practical calculators, and provides a clear way to contact us. It is not an advertising-supported website.

The site does not use display adverts, sponsored placements, analytics scripts, affiliate tracking links, account logins, or newsletter tracking.

Commercial Enquiries

We may still receive enquiries about puzzle books, apps, games, calculators, social coverage, review copies, product testing, or partnerships that relate to the wider Hamilton Digital Media Limited portfolio. Those enquiries can be sent to [email protected].

Reviews And Product Testing

We are open to hearing about relevant puzzle-related products, but receiving a product, app access, review copy, or payment does not guarantee coverage, publication, or a positive opinion.

Affiliate Links And Sponsorships

BrianHamilton.xyz does not currently use affiliate links or sponsored placements. If any page, post, video, or property elsewhere in the network uses an affiliate link, sponsorship, paid placement, or other commercial relationship, the relevant content should disclose that relationship clearly.

Editorial Standards

Commercial relationships should not make our content misleading. Reviews, recommendations, and product mentions should remain relevant, clearly labelled where needed, and useful to the audience of the relevant puzzle or calculator site.
