1. Acceptance of Terms

By creating an account or using any part of the Relentless platform — including our website, mobile applications, and APIs — you agree to be bound by these Terms of Service and our Privacy Policy.
If you are using Relentless on behalf of an organisation, you represent and warrant that you have the authority to bind that organisation to these Terms.
We reserve the right to update these Terms at any time. Material changes will be communicated via email or in-app notification at least 14 days before they take effect. Continued use after changes constitutes acceptance.

You must be at least 16 years of age to use Relentless. Users between 16 and 18 require parental or guardian consent.
You are responsible for maintaining the confidentiality of your account credentials. Any activity under your account is your responsibility.
One person or legal entity may maintain only one free account. Multiple free accounts operated by the same person may be merged or terminated.
You agree to provide accurate, current, and complete information during registration and to update it as necessary.

Relentless offers free and paid subscription tiers. Paid plans are billed in advance on a monthly or annual basis, depending on the plan selected.
All fees are exclusive of taxes unless stated otherwise. You are responsible for applicable taxes based on your jurisdiction.
You may cancel your subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period — no partial refunds are issued for unused time.
We offer a 14-day money-back guarantee for first-time subscribers on annual plans. Refund requests after this window are handled on a case-by-case basis.
We reserve the right to modify pricing with 30 days' advance notice. Price changes do not affect your current billing period.

You may not use Relentless for any unlawful purpose or in any way that could damage, disable, overburden, or impair our servers or networks.
Automated scraping, data mining, or any form of unauthorised data extraction from the platform is strictly prohibited.
You may not attempt to gain unauthorised access to other users' accounts, our systems, or any connected networks.
Content you upload (workout notes, profile photos, etc.) must not contain malware, infringe third-party rights, or include illegal, abusive, or harmful material.
We reserve the right to suspend or terminate accounts that violate these guidelines without prior notice.

All content, branding, design, code, and technology underlying the Relentless platform are owned by Relentless or its licensors and are protected by international intellectual property laws.
Your fitness data remains yours. By using Relentless, you grant us a limited, non-exclusive licence to process and display your data solely to provide the service.
You may not copy, modify, distribute, reverse-engineer, or create derivative works from any part of our platform without prior written permission.
The Relentless name, logo, and all related marks are trademarks of Relentless Inc. Use of our trademarks without authorisation is prohibited.

We strive for 99.9% uptime but do not guarantee uninterrupted or error-free service. Planned maintenance windows will be communicated in advance.
Relentless is a fitness tracking tool, not a medical device. Our analytics and recommendations are for informational purposes only and should not replace professional medical advice.
THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT.
In no event shall Relentless be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the service.

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law principles.
Any disputes arising under these Terms shall first be addressed through informal negotiation. If unresolved within 30 days, disputes will be submitted to binding arbitration under the rules of the American Arbitration Association.
Class action lawsuits and class-wide arbitration are not permitted under these Terms. You agree to resolve disputes on an individual basis only.
Nothing in these Terms limits your rights under applicable consumer protection laws.
