These Terms constitute a legally binding agreement between you ("User," "you") and FLX ("we," "us," "our"). Your continued use of the App following any updates to these Terms constitutes acceptance of those changes.
2. Eligibility
FLX is available exclusively to users who are 18 years of age or older.
By creating an account, you represent and warrant that you are at least 18 years old. FLX is not directed at, intended for, or available to individuals under 18.
FLX reserves the right to terminate any account where this eligibility requirement is not met, without notice and without refund.
3. Account Registration and Security
To access certain features of FLX, you must create an account. By registering, you agree to:

6. Subscription and Payments
6.1 Free and Paid Tiers
FLX offers a free tier with core functionality and a paid subscription tier with enhanced features. The specific features included in each tier are described within the App and may be updated over time.
6.2 Billing
Paid subscriptions are billed on a recurring basis (monthly or annually, as selected). Billing is processed through the applicable app store (Apple App Store or Google Play). FLX does not directly process or store payment information.
6.3 Cancellation
You may cancel your subscription at any time through your app store account settings. Cancellation takes effect at the end of the current billing period. You will retain access to paid features until the end of the period for which you have paid.
6.4 Refunds
Refund eligibility is governed by the refund policy of the applicable app store. FLX does not independently issue refunds outside of app store policies, except where required by applicable law.
6.5 Price Changes
FLX reserves the right to change subscription pricing with reasonable advance notice. Continued use of the paid tier after a price change constitutes acceptance of the new pricing.
7. User Content and Data Ownership
7.1 Your Data
You retain full ownership of the data you input into FLX, including workout logs, personal goals, physical limitations, and conversation history ("User Content").
7.2 License to FLX
By using FLX, you grant us a limited, non-exclusive, royalty-free license to use, store, and process your User Content solely for the purpose of providing and improving the Service. This license does not extend to selling your data or sharing it with third parties for marketing purposes.
7.3 Aggregated Data
FLX may use anonymized, aggregated data derived from user activity to improve the Service, conduct research, and develop new features. This data cannot be used to identify you personally.
8. Intellectual Property
8.1 FLX Ownership
All content, features, design, code, branding, and technology within FLX, including but not limited to the FLX name, logo, and AI systems, are the exclusive intellectual property of FLX and are protected by applicable intellectual property laws. Nothing in these Terms grants you any ownership rights in FLX's intellectual property.
8.2 Restrictions
You may not copy, modify, distribute, sell, reverse engineer, or create derivative works from any part of FLX without our prior written consent.

10. Disclaimers and Limitation of Liability

FLX is provided on an "as is" and "as available" basis without warranties of any kind, express or implied. We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components.
10.2 Limitation of Liability
To the fullest extent permitted by applicable law, FLX and its affiliates, officers, employees, and partners shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of data, loss of revenue, or personal injury, arising out of or in connection with your use of the Service.
10.3 Cap on Liability
In no event shall FLX's total liability to you exceed the amount you paid to FLX in the twelve (12) months preceding the claim, or $100 USD, whichever is greater.
11. Indemnification
You agree to indemnify, defend, and hold harmless FLX and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or related to your use of the Service, your User Content, or your violation of these Terms.
12. Dispute Resolution and Arbitration
12.1 Informal Resolution
Before initiating any formal dispute, you agree to contact us at legal@getflx.app and attempt to resolve the issue informally. We will make a good-faith effort to resolve disputes within 30 days.
12.2 Arbitration
If informal resolution fails, any dispute arising out of or relating to these Terms or the Service shall be resolved through binding arbitration in accordance with the rules of the applicable arbitration authority in your jurisdiction, rather than in court, except where prohibited by law.
12.3 Class Action Waiver
To the extent permitted by law, you waive any right to participate in a class action lawsuit or class-wide arbitration against FLX.
12.4 Exceptions
Nothing in this section prevents either party from seeking injunctive or other equitable relief in cases of intellectual property infringement or unauthorized data access.
13. Force Majeure
FLX shall not be liable for any failure or delay in performance resulting from causes beyond our reasonable control, including but not limited to religious acts, natural disasters, pandemics, government actions, internet outages, or third-party service failures.
14. Termination
14.1 By You
You may terminate your account at any time by deleting it within the App. When you delete your account, you enter a 7-day grace period during which you can restore the account and cancel the deletion. After the grace period ends, your personal data is permanently deleted from our systems, except for limited records we are legally required to keep.
14.2 By FLX
FLX reserves the right to suspend or permanently terminate your access to the Service at any time, with or without notice, for conduct that we determine violates these Terms or is harmful to other users, FLX, or third parties.
14.3 Effect of Termination
Upon termination, your right to use the Service ceases immediately. Provisions of these Terms that by their nature should survive termination, including intellectual property, disclaimers, indemnification, and dispute resolution, will continue to apply.
15. Governing Law
These Terms are governed by and construed in accordance with applicable law in the jurisdictions where FLX is offered. FLX complies with applicable local regulations including:
Where conflicts arise between jurisdictions, we will apply the standard most protective of user rights.
16. Changes to These Terms
FLX reserves the right to update these Terms at any time. We will notify you of material changes via in-app notification or email at least 14 days before changes take effect. Your continued use of the App after that date constitutes acceptance of the updated Terms.
If you do not agree to the changes, you must stop using the Service and may delete your account.
17. Severability
If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will continue in full force and effect.
18. Entire Agreement
These Terms, together with our Privacy Policy, constitute the entire agreement between you and FLX regarding your use of the Service and supersede any prior agreements or understandings.
