These Terms of Service ("Terms") govern your use of websites and applications published by Massfeller LLC ("we," "us," "the LLC"), including massfellerllc.com, HEARTware, M.A.S.S. Trap, TPS League, Homework Forensics, and any future application Massfeller LLC publishes. By accessing or using any of our products, you agree to these Terms. If you do not agree, do not use the products.

1. Who can use the apps

Our apps are private. Access is restricted to users explicitly added to an allowlist by the LLC. There is no public sign-up. If your email address is not on an allowlist, the app will refuse to authenticate you. Attempting to bypass authentication or access controls is a material breach of these Terms.

2. Your account

You are responsible for safeguarding your account credentials and for all activity that occurs under your account. We use Google Federated Sign-In; security of your underlying Google account is your responsibility. Notify us immediately at support@massfellerllc.com if you suspect unauthorized access.

3. Acceptable use

You agree not to:

• Use the apps to violate any applicable law or regulation
• Attempt to gain unauthorized access to any portion of the apps, accounts other than your own, or the LLC's infrastructure
• Reverse-engineer, decompile, or disassemble any portion of the apps except to the extent expressly permitted by applicable law
• Interfere with or disrupt the integrity or performance of the apps
• Use the apps to transmit malware, phishing content, or other malicious payloads
• Use automated means (scrapers, bots) to access the apps without our prior written permission

4. Your content

You retain all rights to content you submit to the apps. You grant Massfeller LLC a non-exclusive, royalty-free license to host, store, transmit, display, and process your content solely for the purpose of providing the apps to you and the other allowlisted users with whom you share access. We do not claim ownership and we do not use your content for any other purpose.

5. Our content

The apps' design, code, copy, and brand elements are the property of Massfeller LLC. We grant you a limited, revocable, non-exclusive, non-transferable license to access and use them within the scope of these Terms. No other rights are granted by implication.

6. Third-party services

The apps integrate with services from Google (Firebase), Cloudflare, Anthropic, Google AI, Spotify, OpenWeather, Apple, and others described in our Privacy Policy. Your use of those services is subject to their own terms. We are not responsible for the practices of third-party services beyond what we control on our side of the integration.

7. Apple App Store users — additional terms

If you obtained the app from Apple's App Store, the following additional terms apply:

• These Terms are between you and Massfeller LLC, not Apple. Apple is not responsible for the app or its content.
• Your license to use the app is limited to a non-transferable license to use the app on Apple-branded devices that you own or control, as permitted by the Usage Rules in Apple's Media Services Terms.
• Apple has no obligation to furnish maintenance or support for the app. Direct all support requests to support@massfellerllc.com.
• Massfeller LLC, not Apple, is solely responsible for the app and its content, including any product warranties.
• Massfeller LLC, not Apple, is responsible for addressing any claims by you or a third party relating to the app.
• Apple and Apple's subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

8. Termination

We may suspend or terminate your access at any time, for any reason, with or without notice. You may stop using the apps at any time and request deletion of your account by emailing support@massfellerllc.com. Upon termination, the rights granted to you under these Terms cease, and we will delete your account data per our Privacy Policy.

9. Disclaimers

The apps are provided "as is" and "as available", without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, non-infringement, or accuracy. We do not warrant that the apps will be uninterrupted, secure, or error-free, nor that defects will be corrected. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

10. Limitation of liability

To the maximum extent permitted by law, Massfeller LLC and its members, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with these Terms or your use of the apps, even if advised of the possibility of such damages. Our total cumulative liability for any direct damages shall not exceed one hundred U.S. dollars (USD $100) or the total amount you paid us in the prior twelve months, whichever is greater.

11. Indemnification

You agree to indemnify and hold harmless Massfeller LLC and its members, employees, and agents from any claim, loss, liability, or expense (including reasonable attorneys' fees) arising from your breach of these Terms, your misuse of the apps, or your violation of any law or third-party right.

12. Governing law and dispute resolution

These Terms are governed by the laws of the State of Wyoming, without regard to its conflict-of-laws principles. Any dispute arising out of or related to these Terms or the apps shall be brought exclusively in the state or federal courts located in Sheridan County, Wyoming, or, where the user is a resident of Florida, in the state or federal courts located in Duval County, Florida, at our election. You consent to the personal jurisdiction of those courts.

13. Changes to these Terms

We may update these Terms. The "Last updated" date at the top will reflect any change. Material changes will be notified in the app. The current version always lives at https://massfellerllc.com/terms/. Continued use of the apps after changes constitutes acceptance.

14. Severability and entire agreement

If any provision of these Terms is held unenforceable, the remaining provisions remain in full effect. These Terms, together with our Privacy Policy, constitute the entire agreement between you and Massfeller LLC concerning the apps.
