Terms of Service

Effective April 25, 2026

These Terms of Service ("Terms") form a binding agreement between you and Signal Forward LLC ("Flux", "we", "us") and govern your access to and use of the Flux web application, marketing site, and related services (collectively, the "Service"). By creating an account or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility and Accounts

You must be at least 16 years old to use the Service. You are responsible for the accuracy of the information you provide, for keeping your credentials secure, and for any activity under your account. Notify us promptly at security@fluxathlete.com if you suspect unauthorized use of your account.

2. Description of the Service

Flux helps athletes import data from connected services (such as Garmin Connect and Strava), computes training and health analytics from that data, and presents the results in dashboards, reports, and notifications. Specific features evolve over time; some features may be labeled "beta" or similar and may be modified or discontinued.

3. Third-Party Services

The Service depends on integrations with third-party platforms including Garmin Connect, Strava, Amazon Web Services, Anthropic, Microsoft Azure Communication Services, and Visual Crossing, among others. Your use of those services is governed by their own terms and privacy policies. Flux is not responsible for the availability, accuracy, or behavior of any third-party service. If a third-party service changes its terms, restricts API access, or becomes unavailable, related Flux features may stop working without notice.

When you connect a third-party account, you authorize Flux to access that account on your behalf for the purposes described in our Privacy Policy. You may revoke that authorization at any time from Settings, from the third-party provider, or both.

4. Acceptable Use

You agree not to:

  • Use the Service in violation of any applicable law or regulation.
  • Reverse-engineer, decompile, or attempt to derive the source code of the Service except where permitted by law.
  • Probe, scan, or test the security of the Service without authorization, or attempt to bypass authentication or rate limits.
  • Use the Service to upload or transmit malware, infringing material, or content that violates the rights of others.
  • Use automated means to scrape, copy, or extract data beyond the access provided by our documented APIs.
  • Resell, sublicense, or redistribute the Service or data obtained through it.
  • Impersonate another person or misrepresent your affiliation with any person or entity.

5. Your Content and Data

You retain all ownership rights in the data you upload, sync, or otherwise submit to the Service ("Your Content"). You grant Flux a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, display, process, derive metrics from, and otherwise use Your Content as needed to operate, secure, and improve the Service for you and to develop and improve our analytics, models, and features generally. We may use de-identified or aggregated data derived from Your Content for any purpose, including benchmarking, research, and product development.

You represent that you have all rights necessary to grant the license above and that Your Content does not violate the rights of any third party.

6. Subscriptions, Trials, and Fees

The Service is currently offered as an early-access product without a paid subscription. We reserve the right to introduce paid plans, free tiers, or other commercial models in the future. If we introduce paid features, we will give you reasonable notice and an opportunity to choose whether to continue.

7. Termination

You may stop using the Service at any time and delete your account from Settings or by contacting us. We may suspend or terminate your account if you violate these Terms, create risk or possible legal exposure for us, or if your use threatens the integrity of the Service. Sections that by their nature should survive termination (including Sections 5, 8, 9, 10, 11, and 12) will survive.

8. Disclaimers

Flux is not a medical device, medical service, or substitute for professional medical advice. Training and health metrics produced by the Service are estimates derived from third-party data and may be inaccurate or incomplete. Always consult a qualified healthcare or coaching professional before making decisions about training, nutrition, medication, or medical treatment.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT DATA WILL BE FREE FROM LOSS OR CORRUPTION.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL FLUX OR ITS AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF FLUX HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. FLUX'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FLUX FOR THE SERVICE IN THE TWELVE MONTHS PRECEDING THE CLAIM OR (B) ONE HUNDRED U.S. DOLLARS ($100).

10. Indemnification

You agree to defend, indemnify, and hold harmless Flux and its officers, directors, employees, and contractors from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in any way connected with (a) your use of or access to the Service, (b) your violation of these Terms, or (c) your violation of any third-party right.

11. Changes to the Service or Terms

We may modify the Service or these Terms at any time. If we make material changes to these Terms we will provide notice (for example, by email or in-app message) before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms.

12. Governing Law and Disputes

These Terms are governed by the laws of the State of Tennessee, United States, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the Service will be brought exclusively in the state or federal courts located in Tennessee, and you consent to the personal jurisdiction of those courts.

13. Miscellaneous

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Flux regarding the Service. If any provision is held unenforceable, the remaining provisions will remain in effect. Our failure to enforce a provision is not a waiver of its later enforcement. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets.
