Terms of use

Last updated 20 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.

Drop-in bookings

Some gyms take drop-in bookings through OpenMapp. Payment is handled by Stripe and goes to the gym, minus OpenMapp's fee. Until January 1, 2027 that fee is $0 and OpenMapp covers the card processing fee. After that, OpenMapp keeps 15% of each paid drop-in and still covers the card processing fee. Free cancellation up to 12 hours before class for a full refund. Later cancellations and no-shows aren't refunded. If the gym cancels the class or turns you away, you get a full refund. Cancel from the link in your confirmation email or from your account page. Refunds go back to the card you paid with, usually within 5–10 business days.

For gyms: when a booking is refunded under this policy, the payout for that booking is reversed. Late cancellations and no-shows aren't refunded, so you keep the payment.
