Terms of use
Last updated: October 13, 2026.
These terms govern the MastersMasters account (masters-masters.com), the single account for the …Masters trading card games. By creating an account, you accept them. Each game also has its own terms, which apply when you play it.
The service
The MastersMasters account is free. It lets you sign up, sign in and join the games with a single username. It is provided “as is,” with no guarantee of continuous availability; it may change or be interrupted for maintenance.
Your account
- You must be at least 15 to create an account.
- One account per person. It’s personal: you can’t lend, share or sell it.
- Your username is the same in every game and can’t be changed once chosen. It must not be offensive, hateful or misleading, or impersonate anyone else: we may replace a username, or restrict, suspend or delete an account that breaks these rules, in a proportionate way. You can contest a decision at the contact address.
- Choose a strong password and keep it secret. You are responsible for activity on your account; tell us right away if someone else uses it.
- If you sign in with Google, Apple or Discord, access to your account also depends on that service and its terms.
Liability
Since the service is free, our liability is limited to the extent permitted by law, in particular in case of interruption. Nothing in these terms limits the rights the law grants you as a consumer.
Changes to these terms
These terms may change. If a change is significant, you will be told before it takes effect. Continuing to use the account afterward means you accept it; otherwise, you can have your account deleted.
Deleting your account
You can ask us to delete your account at any time by writing to contact@masters-masters.com. Deletion applies to every MastersMasters game.
Governing law
These terms are governed by French law. In case of a dispute, write to us first to look for an amicable solution; failing that, the French courts have jurisdiction, subject to the rules that protect consumers.
How we process your personal data is described in our Privacy policy.
