# Brand and Usage Guidelines
Purpose of these guidelines
These guidelines explain how to refer to FermatMind in a clear and non-misleading way. They are intended to protect users from confusion about official identity, source attribution, and endorsement. They do not create a certification program, partnership status, or permission to use FermatMind materials beyond the scope stated here.
Name and identity
Use “FermatMind” for the English product name. The Chinese name “费马测试” may be shown when a bilingual reference is needed. Do not create unofficial abbreviations, authorization labels, certification titles, partner badges, or account names that could be confused with FermatMind official channels.
Accurate references and quotation
Public discussion, commentary, and limited quotation should preserve the original meaning, include source attribution where appropriate, and keep important boundary statements intact. Do not present an excerpt as FermatMind endorsement of a person, organization, course, product, or viewpoint.
Visual and product references
Screenshots, logos, wordmarks, and product visuals should be used only in ways that are accurate, restrained, and not likely to imply official cooperation. Do not alter visual assets or combine them with another mark in a way that suggests sponsorship, certification, or partnership.
Permission-sensitive uses
Commercial promotion, co-branded pages, courses, events, large-scale republication, translated redistribution, white-label use, or asset-pack use may require written permission through official channels. This page does not approve any third-party use by default.
Misleading use
Do not use FermatMind names, content, or visuals to impersonate official services, sell unauthorized copies, imply a verified relationship, or remove attribution. FermatMind may ask for correction or removal when public confusion or rights issues arise.
Public-benefit governance alignment
Brand trust may be connected to youth-first boundaries, clear data boundaries, and public-benefit governance principles, without implying certification, partnership, charity status, third-party endorsement, or market leadership.
