Terms of Service

Last updated: August 9, 2026

These Terms of Service ("Terms") govern your access to and use of Measure of Mind — Queue Studio (the "app", "Service"), operated by Leif Kramer ("we", "us", or "our"). By signing in or using the app, you agree to these Terms. If you do not agree, do not use the app.

The short version

• The app is free to use for now. We may introduce paid plans or limits later, and will update these Terms if we do.
• You get a personal, limited, non-exclusive, non-transferable license to use the app. You may not copy, reproduce, redistribute, resell, or rehost it.
• Sign-in is through Google. You are responsible for your account and for anything you do while signed in.
• The app is provided "as is." We're not liable for damages arising from your use of it.

1. Eligibility

You must be at least 13 years old and able to form a binding contract to use the app. By using it, you represent that you meet these requirements.

2. Your account

• You sign in with Google. We use your Google email and public profile only to identify you and keep your session (see our Privacy Policy).
• You are responsible for keeping your Google account secure and for all activity under your account.
• We may assign an admin role to specific email addresses. Admins can manage users, access codes, and blocked IPs as described in the Privacy Policy.

3. License to use the app

Subject to these Terms, we grant you a personal, limited, revocable, non-exclusive, non-transferable, non-sublicensable license to access and use the app for your own internal, non-commercial purposes.

4. Restrictions

You agree not to, and not to allow anyone else to:

• Copy, reproduce, republish, distribute, publicly display, sell, lease, sublicense, or otherwise exploit the app or any part of it.
• Rehost, mirror, or make the app available on any other domain or service, or create derivative works based on it.
• Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code or underlying ideas of the app, except to the extent applicable law expressly prohibits that restriction.
• Use the app to violate any law or third-party right, or to transmit malware, harmful code, or excessive/automated requests.
• Interfere with, disrupt, or overload the app or its infrastructure, or attempt to gain unauthorized access to it.
• Remove, alter, or obscure any copyright, trademark, or other proprietary notices in the app.

All right, title, and interest in the app — including its software, design, text, branding, and the "Measure of Mind — Queue Studio" name — remain with us. Nothing in these Terms gives you any ownership in the app.

5. Your content

The simulation board models you build are stored in your browser and in files you export yourself; we do not host or store your board models on our servers. You retain all rights in your board models. You are responsible for their content and for backing them up. By importing a file into the app, you represent that you have the right to do so.

6. Acceptable use & enforcement

We may suspend or terminate your access, block your account or IP address, or revoke sessions at any time, without notice, if we believe your use violates these Terms or threatens the Service. We may also modify or discontinue features at any time.

7. Free use & changes to the Service

The app is currently free. We may introduce fees, usage limits, or paid plans in the future. We may also change, limit, or discontinue the Service (or any feature) at any time. We will update these Terms and note material changes on the home page.

8. Disclaimers

The app is provided "as is" and "as available," without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee the app will be uninterrupted, error-free, secure, or accurate. The simulations are educational tools and are not engineering, operational, or professional advice.

9. Limitation of liability

To the fullest extent permitted by law, in no event will we be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or business, arising out of or related to your use of (or inability to use) the app — whether based on warranty, contract, tort (including negligence), or any other theory — even if we have been advised of the possibility of such damages. Our total liability for all claims is limited to the greater of (a) the amount you paid us to use the app in the twelve months before the claim (currently zero, as the app is free), or (b) USD $50.

10. Indemnity

You agree to indemnify and hold us harmless from any claims, damages, or expenses (including reasonable attorneys' fees) arising from your use of the app or your violation of these Terms.

11. Third-party services

The app uses Google Sign-In and Amazon Web Services. Your use is also subject to Google's and AWS's applicable terms and policies. We are not responsible for their services.

12. Termination

You can stop using the app at any time and disconnect it in your Google Account permissions page. We may suspend or terminate your access at any time, for any reason, including for breach of these Terms. Sections that by their nature should survive termination (including restrictions, disclaimers, and liability limits) will remain in effect.

13. Changes to these Terms

We may update these Terms. We will post changes here with a new "Last updated" date and note material changes on the home page. Your continued use after changes take effect means you accept the updated Terms.

14. Governing law

These Terms are governed by the laws of the jurisdiction in which the operator resides, without regard to conflict-of-law principles. Any disputes will be resolved in the courts of that jurisdiction.
