Terms of Use of the TatamiTime app

Last updated: 2 October 2026

This is a translation. The Czech version of these terms is the binding one.

These terms govern the relationship between the operator of the TatamiTime app and the people who use it. By creating an account you agree to them.

1. Operator

The operator is not a VAT payer. He is not entered in the Commercial Register and does business under a trade licence issued by the competent trade licensing office.

2. What the app is for

TatamiTime is an app for people who train Brazilian jiu-jitsu, and for gyms. It serves to:

• find gyms, open mats and seminars nearby,
• see the timetable and the announcements of the gym where you train,
• ask for a pass or an entry and keep track of them (a coach or the gym's owner approves them),
• keep your own training log and a profile with your belt,
• communicate: a feed with posts, the gym's chat and private messages,
• let a gym's owner and coaches run the gym (timetable, price list, passes, attendance, announcements).

The app is free for athletes.

3. Passes and payments

The app is not a payment system and makes no payments. "Buying" in the app means asking the gym for a pass or an entry. You pay directly at the gym (at the reception or to a coach) in the way the gym decides; a coach then confirms the payment in the app and the pass becomes valid.

The contract on membership, a pass or an entry is made between you and the gym. The operator of the app is not a party to it and is not responsible for the gym's services, for prices or for refunds; turn to your gym with those.

4. Account

You need an account to use the app (an e-mail and a password, or signing in with Apple or Google). Give true details, above all your name: by it a coach knows whose payment they are confirming. Keep your sign-in details secret.

The app is meant for people aged 15 and over. Younger people may use it only with the consent of their legal guardian.

You can delete your account at any time right in the app (Profile → Settings → Delete account); see the page Deleting your account and data.

5. What you write in the app

You are responsible for the posts, comments, messages, photos, videos and other content you put into the app. Put in only what you have the right to. The content stays yours; you give the operator permission to show it in the app to those it is meant for, until you delete it or delete your account.

The feed, the chat and messages are governed by the Community Rules, which you accept before your first post and can read at any time in the settings. In particular, the following are not allowed:

• insults, threats, bullying and hate speech,
• pornography and sexual content, violence outside sport, anything that harms children,
• other people's photos, videos and personal data without their consent,
• spam, scams and advertising,
• anything illegal.

We do not tolerate objectionable content or harassment. Every post, comment, message, announcement, seminar and person can be reported in the app, and you can block anyone. We review reports within 24 hours; we delete content that breaks the rules and may ban its author from writing or cancel their account.

6. Gyms in the app

The information about gyms (address, timetable, prices, contacts) comes from public sources or from the gyms themselves and may be incomplete or out of date; check it with the gym before you go. A gym can take over its profile in the app and manage it. Whoever manages a gym in the app is responsible for what they state about it, and for being allowed to process its members' data.

7. What to refrain from

• unauthorised access to other people's accounts and data,
• overloading the app with automated requests and misusing its API,
• pretending to be someone else, especially a coach or the owner of a gym.

Report the loss or disclosure of your sign-in details to the operator.

8. Availability

The operator tries to keep the app running but does not guarantee uninterrupted operation. He is not responsible for outages caused by circumstances beyond his control (outages of the hosting, of the internet connection, of the services of Apple and Google, and the like). He may change the app, add to it and end it.

9. Limitation of liability

The operator is liable for damage caused by a breach of these terms only to the extent set by law. He is not liable for indirect damage, lost profit or damage arising from incorrect use of the app. The app is no substitute for a coach or a doctor; you are responsible for your own health when training.

10. Cancellation of an account by the operator

The operator may restrict or cancel the account of anyone who seriously or repeatedly breaks these terms or the Community Rules, gives untrue details or misuses the app.

11. Personal data protection

The processing of personal data is described in the Privacy Policy.

12. Changes to the terms

The operator may change the terms. He will announce substantial changes by e-mail or in the app at least 14 days in advance. Anyone who does not agree with a change may delete their account.

13. Governing law

The terms and the relationships arising from the use of the app are governed by the law of the Czech Republic. Disputes are decided by the courts of the Czech Republic that have subject-matter and territorial jurisdiction.

A consumer may turn to the Czech Trade Inspection Authority as the body for out-of-court settlement of consumer disputes (www.coi.cz).
