Last updated: July 22, 2026
These Terms of Service ("Terms") are a binding agreement between you and NEPSYN ("NEPSYN," "we," "us," or "our") and govern your access to and use of the NEPSYN mobile application, website, and related services (together, the "App"). By creating an account or using the App, you agree to these Terms. If you do not agree, do not use the App.
PLEASE READ THESE TERMS CAREFULLY. THEY INCLUDE AN ASSUMPTION OF RISK AND RELEASE FOR PHYSICAL EXERCISE (SECTION 4), A LIMITATION OF LIABILITY (SECTION 10), AND A BINDING INDIVIDUAL-ARBITRATION AGREEMENT AND CLASS-ACTION WAIVER (SECTION 13) THAT AFFECT YOUR LEGAL RIGHTS, INCLUDING HOW DISPUTES ARE RESOLVED. YOU MAY OPT OUT OF ARBITRATION AS DESCRIBED IN SECTION 13.
To use NEPSYN, you must create an account with a valid email address or sign in with Google or Apple. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. You must be at least 18 years old to use NEPSYN.
NEPSYN provides a fixed 14-day full-access period when a new account is created. A paid subscription is required to continue using NEPSYN after that period ends.
Prices are in USD and may vary by region. A subscription begins only after you explicitly choose a plan and confirm checkout through the Google Play Store or Apple App Store. Once purchased, subscriptions renew until canceled. To avoid the next charge, cancel before the renewal date shown by the applicable store. You can manage or cancel your subscription through your device's app store settings, and cancellation takes effect at the end of the current paid period.
We reserve the right to change pricing with reasonable notice. Price changes will not affect your current billing period.
Refunds and billing. All subscriptions are purchased through and billed by the Apple App Store or Google Play, which act as the merchant of record. Refunds are handled by the applicable app store under its own policies; NEPSYN does not separately process payments and generally cannot issue refunds directly. Except where required by law or granted by the app store, all charges are non-refundable, and canceling only stops future renewals — it does not refund the current billing period. Any price change is delivered and, where required, consented to through your app store's standard price-change process; if you do not accept an increase, your subscription will not renew at the new price. If you are an EU/UK consumer, statutory withdrawal rights may apply to the extent required by law.
When a new NEPSYN account is created, NEPSYN grants that account one fixed 14-day period of full access. No payment method is required, no App Store or Google Play subscription is created, and nothing is charged automatically when the period ends. Signing in again, reinstalling the app, or changing devices does not restart or extend the period. After it ends, you must explicitly choose and confirm a paid plan to continue using NEPSYN.
If you purchase a subscription before the 14-day period ends, paid billing starts immediately when the store confirms checkout and unused free-access days do not carry over. Accounts included in NEPSYN's approved pre-launch beta cohort receive permanent Legacy Pro feature access for the lifetime of that account, provided the account remains open and in good standing. Legacy Pro is not an App Store or Google Play subscription, has no recurring charge, and does not transfer to another account. Your data will be retained and available if you subscribe after free access ends.
This is a one-time, no-cost access period granted by NEPSYN directly. It is not an App Store or Google Play introductory or promotional offer, and it does not create, or automatically charge, any subscription.
NEPSYN is a fitness tracking and planning tool, not a medical device or service. All metrics provided by the app — including strength scores, recovery readiness scores, BMI calculations, macro recommendations, and AI coaching suggestions — are for informational and educational purposes only. They do not constitute medical, nutritional, or professional health advice.
Consult a qualified healthcare professional before starting any exercise program, making dietary changes, or if you have concerns about your health. If you experience pain, dizziness, or other symptoms during exercise, stop immediately and seek medical attention.
No Professional Relationship. No trainer–client, coach–client, dietitian–client, medical, physical-therapy, fiduciary, or other professional relationship is formed between you and NEPSYN or its AI features by your use of the App. NEPSYN does not provide personal-training, medical, nutritional, physical-therapy, or other licensed professional services, and the App is not a substitute for a licensed professional.
ASSUMPTION OF RISK. YOU UNDERSTAND THAT PHYSICAL EXERCISE, STRENGTH TRAINING, AND DIETARY CHANGES CARRY INHERENT AND SIGNIFICANT RISKS, INCLUDING THE RISK OF SERIOUS INJURY, AGGRAVATION OF A PRE-EXISTING CONDITION, DISABILITY, OR DEATH, AND THAT WORKOUT PROGRAMS, EXERCISE AND SUBSTITUTION SUGGESTIONS, RECOVERY AND STRENGTH SCORES, MACRO AND NUTRITION TARGETS, AND AI-GENERATED CONTENT ARE GENERAL IN NATURE, ARE NOT TAILORED TO YOUR INDIVIDUAL MEDICAL CONDITION, AND MAY BE INAPPROPRIATE FOR YOU. YOU VOLUNTARILY ASSUME ALL SUCH RISKS, WHETHER KNOWN OR UNKNOWN.
RELEASE. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU RELEASE, WAIVE, AND DISCHARGE NEPSYN AND ITS MEMBERS, OFFICERS, EMPLOYEES, CONTRACTORS, AND AGENTS FROM ANY AND ALL CLAIMS, LIABILITIES, DAMAGES, OR EXPENSES ARISING OUT OF OR RELATED TO YOUR USE OF THE APP OR YOUR PERFORMANCE OF ANY ACTIVITY SUGGESTED, GENERATED, OR TRACKED BY THE APP, WHETHER BASED ON NEGLIGENCE OR OTHERWISE. This release does not apply to liability that cannot be released under applicable law, including liability for gross negligence, willful misconduct, fraud, or personal injury or death to the extent non-waivable.
NEPSYN includes AI-powered features, including program generation, coaching chat, exercise and substitution suggestions, memory of stated preferences, and photo/image analysis, provided with the assistance of third-party AI services.
(a) Suggestions only; no reliance. AI-generated content is provided as informational suggestions, not as professional training, medical, nutritional, diagnostic, or other professional advice, and no output creates any professional relationship (see Section 4). AI features may produce information that is inaccurate, incomplete, out of date, or unsuitable for you. You are solely responsible for evaluating any AI output and for deciding whether and how to act on it, at your own discretion and risk. Do not rely on the App for medical, diagnostic, dosage, emergency, or crisis needs; consult a qualified professional or contact emergency services.
(b) Inputs and outputs. You are responsible for the content you submit to AI features. As between you and NEPSYN, you retain any rights you hold in AI outputs generated for you, and NEPSYN grants you a personal license to use programs and other AI content generated for you for your own fitness use. AI-generated content may not qualify for copyright or other ownership protection and is provided "as is"; NEPSYN makes no warranty that outputs are original, accurate, or non-infringing, claims no exclusive rights in them, and similar or identical outputs may be generated for other users. You may not use AI features to obtain or facilitate medical diagnosis, drug or supplement dosing, self-harm, disordered eating, or other dangerous instructions, or to circumvent the App's safety features.
(c) No warranty on AI. AI features are provided "AS IS" and are subject to the disclaimers and limitations in Sections 4 and 10.
You retain ownership of all content you create, upload, or share through NEPSYN, including custom exercises, workout templates, programs, progress photos, measurements, notes, and nutrition logs ("Your Content").
License to us. You grant NEPSYN a worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to host, store, reproduce, back up, modify (for example, to resize, compress, reformat, or generate thumbnails), and display Your Content: (a) to operate, secure, and provide the App to you; and (b) where you choose to share Your Content through social, training-partner, program-sharing, or other user-visible features, to display that content to the other users with whom you share it. This license also permits NEPSYN to use trusted service providers (such as hosting, storage, content-delivery, and AI providers) to carry out these purposes on our behalf. The license for a given item ends when you delete that item or your account, except (i) for content you have already shared with other users, (ii) to the extent the content persists in routine backups for a limited period, and (iii) as required by law.
Your responsibility and warranty. You represent and warrant that you own or have all rights necessary to upload and share Your Content and to grant the license above, and that Your Content does not violate any law or any third-party right, including intellectual-property, privacy, or publicity rights. You are responsible for Your Content and for any content you import (see Section 9).
Our Community Guidelines explain these rules and the reporting, blocking, appeal, and enforcement process in plain language. The Community Guidelines form part of these Terms. If the two conflict, these Terms control.
You agree not to:
You may delete your account at any time through the app. We may suspend or terminate accounts that violate these Terms. Upon termination, your data will be deleted in accordance with our Privacy Policy.
NEPSYN allows you to import workout data from other fitness apps (Strong, Hevy, Fitbod) via CSV/JSON files. You are responsible for ensuring you have the right to export and import this data. We are not affiliated with these third-party apps.
The App integrates, links to, or relies on third-party services and data, including AI providers, nutrition databases (such as USDA FoodData Central and Open Food Facts), exercise-media providers, app-store billing, analytics, and crash-reporting services. NEPSYN does not control and is not responsible for the accuracy, availability, legality, or content of these third-party services, which may be governed by their own terms and privacy policies. Nutrition, exercise, and AI-derived information may be inaccurate or incomplete; you should independently verify anything on which you rely.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEPSYN DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY THAT THE APP WILL BE UNINTERRUPTED, TIMELY, SECURE, ACCURATE, OR ERROR-FREE, OR THAT DATA WILL ALWAYS BE PRESERVED.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEPSYN WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS, REVENUE, OR GOODWILL, ARISING OUT OF OR RELATED TO THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NEPSYN'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE APP WILL NOT EXCEED THE GREATER OF (a) THE AMOUNTS YOU PAID NEPSYN IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (b) US $100.
Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under applicable law, including liability for gross negligence, willful misconduct, or fraud, or for personal injury or death to the extent non-waivable. Some jurisdictions do not allow certain exclusions or limitations, so some of the above may not apply to you.
We may update these Terms from time to time. We will notify you of material changes through the app or by email. Continued use of the app after changes constitutes acceptance of the updated Terms.
These Terms, and any dispute arising out of or relating to these Terms or the App, are governed by the laws of the State of Michigan, without regard to its conflict-of-laws rules and excluding the U.N. Convention on Contracts for the International Sale of Goods. Subject to the arbitration agreement in Section 13, you and NEPSYN agree that the exclusive venue for any dispute not subject to arbitration is the state and federal courts located in Michigan, and each party consents to the personal jurisdiction of those courts and waives any objection to venue there.
PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES YOU AND NEPSYN TO RESOLVE MOST DISPUTES THROUGH BINDING INDIVIDUAL ARBITRATION AND WAIVES YOUR RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION.
(a) Agreement to arbitrate. You and NEPSYN agree that any dispute, claim, or controversy arising out of or relating to these Terms or the App (a "Dispute") will be resolved by binding, individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, and not in court, except as provided below. The Federal Arbitration Act governs the interpretation and enforcement of this Section.
(b) Small-claims and IP carve-out. Either party may bring an individual claim in small-claims court if it qualifies, and either party may seek injunctive or equitable relief in court for actual or threatened infringement or misuse of intellectual property or unauthorized access to the App.
(c) CLASS-ACTION AND JURY WAIVER. YOU AND NEPSYN AGREE TO BRING CLAIMS ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS OR PRESIDE OVER ANY CLASS OR REPRESENTATIVE PROCEEDING. YOU AND NEPSYN EACH WAIVE ANY RIGHT TO A JURY TRIAL.
(d) Coordinated / mass arbitrations. If 25 or more similar arbitration demands are filed by or with the coordination of the same or coordinated counsel, the demands will be administered in staged batches, and any applicable fees will be allocated accordingly; the arbitrator and administrator have authority to implement this batching.
(e) 30-day right to opt out. You may opt out of this Section 13 by emailing support@nepsyn.com with your name, the email on your account, and a clear statement that you opt out of arbitration, within 30 days of first accepting these Terms. Opting out does not affect any other part of these Terms.
(f) Non-severability of the class waiver. If the class-action waiver in Section 13(c) is found unenforceable as to any Dispute, then this entire Section 13 (arbitration agreement) is void as to that Dispute only, and that Dispute will proceed in the courts identified in Section 12; the remainder of these Terms remains in effect. Except as stated in this subsection, if any other part of this Section 13 is found unenforceable, it will be severed and the rest of Section 13 enforced.
You agree to indemnify, defend, and hold harmless NEPSYN and its affiliates, members, officers, employees, and agents from and against any claims, damages, liabilities, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) Your Content or your use of the App; (b) your violation of these Terms or of any law; (c) your infringement or violation of any third-party right, including intellectual-property, privacy, or publicity rights; or (d) data you import from third-party services without proper authorization. NEPSYN may assume the exclusive defense and control of any matter subject to indemnification, and you agree to cooperate with our defense.
NEPSYN respects intellectual-property rights and maintains a Copyright and DMCA Policy describing notices, counter-notices, restoration, and repeat-infringer handling.
Copyright notice. If you believe content on the App infringes your copyright, email support@nepsyn.com with the information required by our Copyright and DMCA Policy. This is NEPSYN's current copyright-complaint contact. NEPSYN does not represent that this contact is registered with the U.S. Copyright Office unless the public policy displays the registered agent's exact name, physical address, telephone number, email address, and current directory verification.
Counter-notice. A user whose material was removed for alleged infringement may submit a counter-notice containing the information required by the Copyright and DMCA Policy, including the user's name, address, telephone number, signature, required statements under penalty of perjury, consent to federal-court jurisdiction, and agreement to accept service of process.
Repeat infringers. NEPSYN will, in appropriate circumstances, disable or terminate accounts of repeat infringers and may remove or disable access to material when infringement is apparent or a valid notice is received.
The App, including its software, design, user interface, the NEPSYN name, logo, and wordmark, and all exercise, program, and food-database content that NEPSYN provides, is owned by NEPSYN or its licensors and is protected by intellectual-property laws. Subject to these Terms, NEPSYN grants you a limited, personal, non-exclusive, non-transferable, revocable license to use the App for your own personal, non-commercial fitness tracking. You may not copy, resell, redistribute, scrape, or create derivative works from the App or NEPSYN's content except as expressly permitted, and you may not use NEPSYN's names or marks without our prior written permission.
NEPSYN is not liable for any failure or delay in performance caused by events beyond its reasonable control, including internet, cloud, or hosting outages, failures or changes of third-party services or app stores, acts of God, natural disasters, epidemics, government action, labor disputes, or other force-majeure events.
Severability. If any provision of these Terms (other than as addressed in Section 13(f)) is held invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if it cannot be modified, severed, and the remaining provisions will remain in full force and effect.
No waiver. NEPSYN's failure to enforce any provision is not a waiver of it.
Assignment. You may not assign these Terms without our consent; NEPSYN may assign them in connection with a merger, acquisition, or sale of assets.
Entire agreement; authoritative version. These Terms, together with the Privacy Policy and Community Guidelines, are the entire and exclusive agreement between you and NEPSYN regarding the App and supersede all prior or contemporaneous terms, including any differently worded terms displayed within the App. The authoritative version of these Terms is the version published at https://www.nepsyn.com/terms; in the event of any conflict, that published version controls.
