Trademark & Brand Guidelines

Last updated October 26, 2026

Draft: this document hasn't been reviewed by counsel yet and isn't in force. It describes how the service works today; the final version will replace it.

You're welcome to write about Underpass, link to it, and say your product works with it. These guidelines keep it clear who made what.

The name

  • Write it as Underpass: one word, capital U. Not "UnderPass" or "Under pass".
  • Use it to refer to our product, not as a verb or a general term for private networks.
  • Don't put it in your own product, company or domain name.
Underpass logo for dark backgrounds
Underpass logo for light backgrounds
  • Use the files as they are: don't change the colors, proportions or lettering, or add effects.
  • Give it room: clear space around it at least the height of the X mark.
  • Use the dark-background version on dark colors and the light one on light colors.

Fine without asking

  • Articles, reviews, tutorials and talks about Underpass.
  • "Works with Underpass" or "for Underpass", when it's true.
  • Linking to our site with the name or logo.

Ask us first

  • Anything that suggests we sponsor, endorse or partner with you.
  • Merchandise, ads or co-branded material using our name or logo.
