OPEN DESIGN, PROTECTED NAME
Build it, sell it — just not as “Yeah Hand.”
The design is fully open source. Build one, modify it, even sell your own version under your own name — we’d genuinely like to see it out in the world. “Yeah Hand” itself is a registered EU trademark, so that specific name and our branding are the one thing that need our OK first.
You’re welcome to
- Build, modify, and use the open-source design for yourself
- Sell a product based on the design under your own name
- Say it’s “based on” or “compatible with” the Yeah Hand, if that’s accurate
- Write about, review, teach, or research the project
- Share an unofficial fork or community project, clearly marked as such
Needs our OK first
- Selling or advertising a product called “Yeah Hand” or something confusingly similar
- Using the Yeah Hand name or logo as a brand on products, packaging, or shop pages
- Implying a product is official, endorsed, or certified by us
