Terms of Service

Last Updated: August 1, 2026

1. Acceptance of Terms

By accessing or using ClubMeister, you agree to be bound by these Terms of Service. If you disagree with any part of the terms, then you may not access the service.

2. Registration and Account

To use certain features of ClubMeister, you must register for an account. You agree to provide accurate, current, and complete information during the registration process and to update such information to keep it accurate, current, and complete.

3. User Conduct

You agree not to use ClubMeister in ways that:

• Violate any local, state, national, or international law or regulation.
• Harass, threaten, or defame any person or entity.
• Interfere with or disrupt the service or servers.
• Attempt to gain unauthorized access to the service or user accounts.

5. AI Connections (Claude, ChatGPT and similar assistants)

ClubMeister can be connected to a third-party AI assistant through our MCP connector. This section applies only if a team admin chooses to use it. Nothing is connected by default.

5.1 What you are doing when you connect

Connecting an assistant instructs ClubMeister to transmit the connected team's data — which includes personal data about other members, such as their names, roles, attendance and, where you request it, their contact details — to an AI provider you have selected. We are not a party to your relationship with that provider, we do not select or endorse it, and we receive nothing back from it.

5.2 Your warranties as a connecting admin

By connecting an assistant you represent and warrant, for as long as the connection remains active, that:

• you are authorised by your club or team to make this decision, and doing so does not breach that club's rules, constitution or internal policies;
• you have a valid legal basis for transmitting the team's personal data to the provider you have chosen, and have put in place any data-processing agreement or international-transfer safeguard your club requires;
• you have informed the members of the connected team, before connecting, that an AI assistant is connected, which one it is, and what it can access, and that you will deal with any objection they raise — including by disconnecting;
• you have read the provider's terms, including any terms permitting it to retain the data or use it to train its models;
• you will keep the assistant account secure, and you accept that anything the assistant retrieves then sits in that account, outside ClubMeister, where we can neither see nor delete it; and
• you will disconnect when the connection is no longer needed, when you cease to be an admin of that team, or when your club asks you to.

5.3 What we do and do not do

We provide the connector, the admin-only gate, single-team scoping, per-request permission checks and an audit log, so that these decisions can be made deliberately and reviewed afterwards. We do not review, approve or supervise individual connections, and we do not monitor what you ask an assistant to do. We may suspend or remove the connector, in whole or for a particular account, where we reasonably believe it is being misused.

5.4 Outputs are not advice

AI assistants make mistakes, including confident ones. Output produced through the connector may be inaccurate, incomplete or out of date, and actions taken through it — creating or cancelling an event, setting an RSVP, publishing a post or poll — take effect immediately and notify your members. You are responsible for checking what an assistant proposes before you approve it, and for the consequences of anything it does on your instruction. Nothing produced through the connector is advice of any kind.

5.5 Responsibility between us

To the fullest extent permitted by law, and without limiting any right you have that cannot lawfully be excluded, you are responsible for claims arising from your decision to connect an assistant, from a failure to meet the warranties in clause 5.2, or from the acts of a provider you selected. This clause does not affect our own responsibility for how we operate ClubMeister itself, or any liability that cannot be excluded under applicable law — including a data subject's rights under the GDPR, which no agreement between us can remove.

6. Intellectual Property

The ClubMeister service, including its original content, features, and functionality, is owned by ClubMeister and is protected by international copyright, trademark, and other intellectual property laws.

7. Termination

You may stop using ClubMeister and delete your account at any time.

We may suspend or terminate an account for good cause — in particular a material or repeated breach of these Terms, conduct that harms other users or us, or use that is unlawful. Where the breach can be remedied, we will normally warn you first and give you a reasonable opportunity to put it right, unless the breach is serious enough that waiting is unreasonable. We may also discontinue the free service, or a free part of it, on reasonable notice.

Paid plans may be terminated by either party in accordance with the term and notice period agreed at purchase. Statutory rights of termination for good cause remain unaffected.

8. Liability

We are liable without limitation for damage caused intentionally or by gross negligence, for injury to life, body or health, under the German Product Liability Act (Produkthaftungsgesetz), and to the extent we have given a guarantee.

For slight negligence we are liable only where we breach a material contractual obligation — an obligation whose fulfilment makes proper performance of this agreement possible in the first place, and on whose observance you may regularly rely. In that case our liability is limited to the damage typically foreseeable for this kind of contract.

Any further liability is excluded. This applies equally to the personal liability of our employees, representatives and agents.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, and nothing affects your rights as a consumer or any data subject's rights under the GDPR.

9. Governing Law and Jurisdiction

ClubMeister is operated from Germany. These Terms and any dispute arising out of or in connection with them are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods.

If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you are habitually resident (Art. 6(2) Rome I Regulation). You may bring proceedings in the courts of your place of residence, and we will bring proceedings against you only there.

If you are a merchant, a legal person under public law or a special fund under public law, the exclusive place of jurisdiction is our registered place of business.

We are neither obliged nor willing to take part in dispute-resolution proceedings before a consumer arbitration board (§ 36 VSBG).

10. Right of Withdrawal (Consumers)

If you are a consumer resident in the EU and you take out a paid plan, you have the right to withdraw from that contract within 14 days without giving any reason. The period begins on the day the contract is concluded.

To withdraw, tell us your decision by a clear statement — an email to support@clubmeister.app is enough. Sending the notice before the period expires is sufficient to meet the deadline. If you withdraw, we will refund all payments received from you without undue delay and at the latest within 14 days of being informed.

Where you have expressly asked us to begin providing the service during the withdrawal period, and acknowledged that you lose the right of withdrawal once the service has been supplied in full, the right lapses on full performance. Where the service has only been partly supplied, you owe a proportionate amount for what was provided up to your withdrawal.

11. Changes to These Terms

We may update these Terms of Service from time to time. We will notify you of any changes by posting the new terms on this page and updating the "Last Updated" date.
