Terms of Service

These Terms of Service ("Terms", "Agreement") constitute a legally binding agreement entered into between you ("User", "Athlete", or "you") and Kratos ("Kratos", "we", "us", or "our") governing your download, installation, access, and use of the Kratos mobile application (Android Package: app.kratos.strength), website, and associated services (the "Service").

By installing, accessing, or utilizing any portion of the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree to these Terms, you must immediately cease using and uninstall the Service. You represent and warrant that you are at least 18 years of age (or have reached the age of majority in your jurisdiction) and possess full legal capacity to enter into this Agreement.

PLEASE READ THIS SECTION CAREFULLY. STRENGTH TRAINING CARRIES INHERENT PHYSICAL HAZARDS:

• NO MEDICAL OR HEALTHCARE ADVICE: Kratos is strictly a digital strength logging, progression tracking, and athletic planning application. Kratos does NOT provide medical advice, physical therapy, clinical diagnosis, rehabilitation prescriptions, or emergency healthcare services. The content, calculations, and recommendations provided through the Application are for educational and informational athletic purposes only.

• MANDATORY PHYSICIAN CONSULTATION: Heavy weightlifting, resistance training, cardiovascular conditioning, and progressive overload impose significant strain on the musculoskeletal and cardiovascular systems. You MUST consult a qualified, licensed physician or medical professional before commencing any new workout regimen, following programmed splits, or significantly increasing training intensity, particularly if you have any pre-existing medical conditions, chronic pain, hypertension, cardiovascular history, or recent surgical procedures.

• VOLUNTARY ASSUMPTION OF ALL RISKS: YOU EXPRESSLY ACKNOWLEDGE AND VOLUNTARILY AGREE THAT YOUR PARTICIPATION IN WEIGHTLIFTING AND RESISTANCE TRAINING INVOLVES INHERENT AND UNPREDICTABLE RISKS OF SERIOUS BODILY INJURY, ILLNESS, PERMANENT DISABILITY, HEART ATTACK, STROKE, RHABDOMYOLYSIS, OR DEATH. YOU VOLUNTARILY ASSUME FULL RESPONSIBILITY AND LIABILITY FOR ANY AND ALL RISKS, DAMAGES, LOSSES, OR INJURIES SUSTAINED IN CONNECTION WITH YOUR EXERCISE ACTIVITIES.

• IMMEDIATE CESSATION UPON ADVERSE SYMPTOMS: If you experience sharp pain, dizziness, lightheadedness, shortness of breath, joint clicking accompanied by pain, nausea, or chest tightness at any time during physical training, STOP EXERCISING IMMEDIATELY AND SEEK EMERGENCY MEDICAL CARE.

• PROBABILISTIC MACHINE LEARNING OUTPUTS: The AI Coach and generative intelligence features within Kratos utilize large language models (including Google Gemini) to generate workout recommendations, split modifications, volume allocations, and recovery suggestions based on algorithmically analyzed inputs.

• NOT A CERTIFIED IN-PERSON TRAINER: Artificial intelligence outputs do NOT replace hands-on supervision by a Certified Strength and Conditioning Specialist (CSCS), licensed athletic trainer, or biomechanics professional. Generative models may produce inaccuracies, suboptimal load estimates, or recommendations that fail to reflect real-time physical exhaustion or individual anatomical variations.

• ATHLETE RESPONSIBILITY & INDEPENDENT JUDGMENT: You are solely responsible for evaluating the safety, suitability, and appropriateness of any exercise, load (weight), rep range, or split suggested by the AI Coach. Never attempt a recommended lift that exceeds your physical ability, technique competence, or gym environment safety capacity.

• Account Security: You are responsible for safeguarding your authentication credentials and for all activities that occur under your account. Notify us immediately of any unauthorized access at huuquoc7603@gmail.com.

• Accurate Information: You agree to provide truthful and accurate information regarding your training parameters and identity.

• Prohibited Conduct: You agree not to: (a) reverse-engineer, decompile, or disassemble the Application; (b) exploit, circumvent, or probe application security mechanisms; (c) inject automated bots, scrapers, or denial-of-service payloads; (d) abuse API rate limits or introduce malicious code; or (e) use the Service for any unlawful or unauthorized purpose.

The Service, including its proprietary codebase, visual design, user interface elements, branding, logo assets, exercise database taxonomy, and mathematical stimulus algorithms, is the exclusive intellectual property of Kratos and is protected by copyright, trademark, and trade secret laws.

Subject to your continuous compliance with these Terms, Kratos grants you a revocable, non-exclusive, non-transferable, non-sublicensable, limited personal license to download, install, and execute the Application solely for your personal, non-commercial fitness tracking purposes.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.

KRATOS SPECIFICALLY DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, TIMELINESS, UNINTERRUPTED AVAILABILITY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL MEET YOUR SPECIFIC ATHLETIC GOALS OR THAT THE OPERATION OF THE APPLICATION WILL BE ERROR-FREE OR VIRUS-FREE.

TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW, IN NO EVENT SHALL KRATOS, ITS DEVELOPERS, AFFILIATES, OFFICERS, AGENTS, OR SUPPLIERS BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR PHYSICAL INJURY, LOSS OF LIFE, MEDICAL EXPENSES, LOSS OF DATA, LOSS OF PROFITS, OR EQUIPMENT DAMAGE), ARISING OUT OF OR IN CONNECTION WITH YOUR ACCESS TO, USE OF, OR INABILITY TO USE THE SERVICE, REGARDLESS OF THE LEGAL THEORY (TORT, CONTRACT, STRICT LIABILITY, OR OTHERWISE), EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT SHALL THE TOTAL AGGREGATE LIABILITY OF KRATOS FOR ALL CLAIMS ARISING UNDER OR RELATING TO THESE TERMS EXCEED THE GREATER OF (A) THE TOTAL AMOUNT ACTUALLY PAID BY YOU TO KRATOS FOR ACCESS TO THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) FIFTY UNITED STATES DOLLARS ($50.00 USD).

You agree to defend, indemnify, and hold harmless Kratos, its developers, affiliates, and representatives from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your violation of these Terms; (b) your misuse of the Service; (c) your physical training activities, exercises, or workouts; or (d) your infringement of any third-party rights.

These Terms remain in effect until terminated by either you or Kratos. You may terminate these Terms at any time by ceasing all use of the Service, uninstalling the Application, and submitting an account deletion request. Kratos reserves the right, in its sole discretion, to suspend, terminate, or restrict your account and access to the Service at any time, with or without notice, for conduct violating these Terms or harmful to the Service or other athletes.

These Terms shall be governed by and construed in accordance with the substantive laws applicable to digital software distribution, without giving effect to conflict of laws principles. If any provision of these Terms is deemed unlawful, void, or unenforceable, that provision shall be severed without affecting the validity and enforceability of the remaining provisions. These Terms constitute the entire agreement between you and Kratos regarding the Service.
