For people who train

Your belt, confirmed by the school that gave it.

Anyone can type “black belt” in a bio. On Onlyoss, your school confirms your rank, so it travels with you: to a new gym, a seminar, an open mat.

Sample profile

A belt in a bio proves nothing.

You earned your rank over years, on the mat. Online it sits next to ranks nobody earned, and nobody can tell them apart.

  • New gym, back to zero.

    Move city or drop in somewhere new, and you have to prove yourself all over again.

  • Your results live in screenshots.

    Wins, losses and draws scattered across brackets, phones and group chats.

  • Anyone can claim what you earned.

    A photo of a belt ceremony can't be checked by a stranger on the other side of the world.

One difference. It changes everything.

You say what your rank is. The school that awarded it confirms it, from its own account. Neither of you can make the gold mark alone.

$12 a year. Their name, on your rank.

What $12 a year buys

One athlete membership keeps your profile public, with every art you train on it. Your rank is never part of the deal: only your school can confirm it.

$12 a year

$1 a month, paid once a year.

  • $12 a year for life if you join by 29 Nov 2026. After that, $66 a year.
  • Once you have paid, $12 a year stays your price for life, even if you stop and come back later.
  • If your school is on Grow or Pro, ask them: your membership may be included.
  • Give a year as a gift to your coach or a training partner.

How many years?
After 29 November it's $66 a year. 1 year is a subscription: it renews every year at the price you joined at, until you cancel. 2 to 4 years are one payment, starting today, and do not renew. Next, make your free account. Then you go straight to payment for the option you picked. Refund Policy. Refunds are the amount paid minus the payment processor's fee (Polar: 5% + $0.50). Payment is taken by Polar, our reseller.

  • Your own page

    onlyoss.com/yourname, with a QR code that opens it on any phone. No app to install.

  • Your rank, with your school's name

    The gold mark shows who awarded it. A stranger can check it in seconds.

  • Your competition record

    Your wins, losses and draws in one line, marked as your own word so nobody mistakes it for more.

  • A sparring record nobody can inflate

    Sparring results your partner agreed to. Gi and no-gi kept apart.

  • Sparring requests

    Ask to spar with people who train what you train, and let them ask you. Opens later this month.

  • Your card for stories and posts

    A picture of your page with your name, art and rank, ready to post or put in your story.

  • Daily quote cards

    5 a day: a motivational quote with your name, your art and your rank on it, for your stories and posts.

Three steps. Your school does the last one.

  1. Create your account

    Free, in about a minute. Your page is onlyoss.com/yourname.

  2. Add your art and your rank

    And the school that awarded it. Every art you train, each with its own rank.

  3. Your school confirms it

    The gold mark appears with their name. Until then it shows as self-declared.

Questions, answered

Creating an account and signing in are free. The membership is what makes your profile public. Nobody can buy a confirmation: only your school gives it.

Read our content guidelines

Does my school include it?
Ask them. A school on Pro includes memberships for 20 of its students with its plan, and on Grow for 5.
I already have an account.
Memberships opened on 30 Sep 2026. Every account made before then stays public free until 29 Nov 2026.
What if I don't renew?
A profile without a membership is hidden, never deleted. You can still sign in, and it comes back when you renew.
My school isn't on Onlyoss yet.
Your rank shows as self-declared until they confirm it. Send them your page: confirming ranks costs the school nothing.
I train more than one art.
Add each one, with its own rank and the school that awarded it. One membership covers them all.
Will I show on my school's page?
Only if you choose to be listed.

Your rank took years. Put your school's name on it.
