Terms of use

Mat Sides watches a public IBJJF athletes list, researches the names on it, projects a likely first-round bracket, and emails you if the list changes.

You must be old enough to make an account, or have a parent on the alert email.

If you watch a division, you agree to these terms and to the privacy policy.

We are not the International Brazilian Jiu-Jitsu Federation.

We are not the official draw.

A projected first round is a projection from the public list and from Grand Slam then overall points.

The real first match is whatever IBJJF posts.

Weigh-ins, the bullpen, and the mat are the event’s, not ours.

Keep the email on the account as the inbox you want alerts on.

Save the name the way it is registered on the list.

Do not share the sign-in.

You are responsible for what happens on the account.

We can close an account that is used to abuse the list, the email, or other people.

We read public athletes lists only.

Do not ask us to log into IBJJF as you.

A list can move after we look.

An email can be late, filtered, or fail.

Check the IBJJF list yourself before you travel if the day is close.

We will never sell your data.

We will never share it with advertisers, data brokers, or anyone who wants a list of competitors.

The privacy policy says how we keep it, who helps us run the site, and how you delete it.

Use Mat Sides to watch a division you care about.

Do not try to break the site, scrape it as a feed, or overload the list checks.

Do not use Cora to invent opponents, seeds, or withdrawals.

Do not paste anyone’s password or a private IBJJF login.

If a name is wrong, a projection is wrong, or an email does not land, we will try to fix the watch.

We are not responsible for a missed match, a missed cut, a flight, or a hotel.

The site is offered as it is.

If a court still finds we owe you money, that amount is the greater of what you paid us in the last twelve months or ten US dollars.

You have not paid us yet.

We can update these terms.

The new date will be on this page.

If you keep using Mat Sides after that, you accept the new terms.

Report an issue or suggest a change from the site, or write privacy@matsides.com.
