Terms of Service
for the Mastermind9 App (the “App”)
Effective date: 22 September 2026
1. Introduction and acceptance
These Terms of Service (“Terms”) govern your access to and use of the App, provided by Outside Ideas Ltd, trading as Mastermind9 (“Mastermind9”, “we”, “us”, “our”), a company registered in England and Wales with its registered office at 2nd Floor Wessex House, 127 High Street, Hungerford, England, RG17 0DL.
By creating an account or otherwise using the App, you agree to these Terms and to our Privacy Policy. If you don’t agree, please don’t use the App.
2. Who can use the App
3. Your account
4. What the App is for
The App is a tool to support the accountability, planning and target-tracking side of your mastermind group membership — for example, setting goals, logging progress, and sharing business performance information with your coach. It is a support tool for your mastermind group, not a substitute for professional financial, legal, tax or business advice, and Mastermind9 does not provide such advice through the App.
5. Your content and data
6. Acceptable use
When using the App, you agree not to:
7. Third-party services
The App relies on third-party infrastructure to operate, including Supabase for hosting, authentication and data storage. Details of how these services handle personal data are set out in our Privacy Policy.
8. Changes to, and availability of, the App
We may update, change or discontinue features of the App from time to time, and may need to suspend access for maintenance or in response to technical issues. We’ll try to give reasonable notice of any change that materially affects your use of the App, but we can’t guarantee the App will always be available or error-free.
9. Fees
Access to the App is included as part of your Mastermind9 membership fee. There is no separate or additional charge for using the App. Payment and cancellation of your membership itself is governed by your Membership Terms, not by these Terms. If we ever introduce a separate charge for the App, we’ll update these Terms and let you know before it applies.
10. Intellectual property
The App, and all software, design, branding and content within it (other than content you submit yourself), belongs to Outside Ideas Ltd or its licensors. You may use the App for your own personal accountability purposes as part of your membership, but may not copy, resell, or create derivative works from it.
11. Disclaimers and liability
The App is provided on an “as is” and “as available” basis. We don’t promise it will be uninterrupted, secure, or free from errors.
Nothing in these Terms excludes or limits our liability for death or personal injury caused by negligence, fraud, or anything else which can’t legally be excluded or limited under English law.
Subject to that, to the fullest extent permitted by law, we won’t be liable for any indirect or consequential loss arising from your use of the App, and our total liability to you in connection with the App will be limited to £500 in total.
12. Termination
13. Data protection
Our Privacy Policy explains how we collect, use and protect your personal data through the App, and forms part of these Terms.
14. Changes to these Terms
We may update these Terms from time to time, for example as the App’s features develop. We’ll let you know about significant changes, and continued use of the App after a change takes effect means you accept the updated Terms.
15. Governing law
These Terms are governed by the law of England and Wales, and any disputes will be subject to the exclusive jurisdiction of the courts of England and Wales.
