Terms of use

Last updated 9 September 2026

OpenMapp is a manually researched directory of Brazilian Jiu-Jitsu gyms in the contiguous United States. You may use the site to find a place to train. You may not copy, scrape, or republish the catalog as a competing product.

The catalog

Gym names, addresses, and class times often come from the gyms themselves. OpenMapp’s work is the selection, verification, classification (Gi, No-Gi, open mat, drop-in policy), listed prices where we have them, and the compiled timetable. That compilation is OM-BA-CATALOG-2026. Facts are not a free license to dump our database onto another site.

What you may do

• Browse the map and directory for personal use.
• Share a link to a gym or city page.
• Suggest a correction when a listing is wrong.

What you may not do

• Scrape, crawl, or bulk-download listings, schedules, or drop-in data for reuse.
• Republish OpenMapp’s compiled catalog, in whole or in substantial part.
• Use bots to hammer research, add-gym, or API routes.
• Remove notices that identify the compilation as OpenMapp’s.

Accounts

If you create an account, we store your email, a hashed password, and the gyms you mark as want-to-go or visited. Sign out from the account page. Do not use a password you use anywhere else.

Gyms and travelers

Always confirm with the gym before you drop in. Policies and prices change. OpenMapp is not the gym and does not sell memberships.

Contact

For permissions or to report copying, use the suggestion flow on a gym listing or email from the site operator’s published contact.
