Terms of Service

Last updated: August 20, 2026

These terms govern your use of the Arc Fitness iOS app and the arcfitness.app website (together, “Arc” or “the Service”). By using either one, you agree to these terms with Crown Haven Ventures LLC, a California limited liability company doing business as Arc Fitness (“we,” “our,” or “us”). If you don’t agree, don’t use Arc.

You must be at least 13 years old to use Arc. If you are under 18, you may use Arc only with the involvement of a parent or guardian who agrees to these terms on your behalf.

The service

Arc is a fitness tracking app that lets you log workouts, track progress, and build exercise habits, along with a website that describes it and can build you a starting plan. We may update, modify, or discontinue features at any time.

Subscriptions

Arc Coach is offered as an auto-renewable subscription in two tiers: Arc Coach at $9.99 per month and Arc Coach Pro at $14.99 per month. Prices are in USD and may vary by region. The current price and subscription length are always shown in the app before you confirm a purchase.

  • Payment is charged to your Apple ID account when you confirm the purchase.
  • Your subscription renews automatically for the same one-month period unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
  • You can manage your subscription and turn off auto-renewal in your Apple ID account settings at any time after purchase. Canceling stops the next renewal; the current period stays active until it ends.
  • If a free trial is offered, any unused portion is forfeited when you purchase a subscription.
  • Subscriptions are billed and managed by Apple. Refunds are handled by Apple under the Apple Media Services Terms of Service; we cannot issue refunds directly.

Your account

  • You must provide a valid email address to create an account.
  • You are responsible for keeping access to your email secure and for all activity under your account. Tell us promptly if you think someone else has gotten into it.
  • You may delete your account at any time from settings. See the privacy policy for exactly what deletion removes and what is kept.

Acceptable use

You agree not to:

  • Use Arc for any unlawful purpose
  • Attempt to access other users’ data
  • Reverse engineer, decompile, or disassemble the app
  • Interfere with or disrupt Arc’s infrastructure

Assumption of risk and liability waiver

Exercise carries inherent risks, including muscle strain, joint injury, cardiovascular events, and in rare cases, serious harm or death. By using Arc, you acknowledge and accept these risks.

Arc is a workout logging and planning tool. It is not a substitute for medical advice, diagnosis, or treatment, and is not provided by licensed medical or fitness professionals. Consult a qualified healthcare provider before starting any exercise program, especially if you have any medical condition, injury, or concern.

You are solely responsible for your own safety. You agree to exercise within your own physical limits, use proper form, warm up appropriately, and stop immediately if you feel pain, dizziness, or any symptom of injury or illness.

TO THE FULLEST EXTENT PERMITTED BY LAW, YOU RELEASE AND HOLD HARMLESS CROWN HAVEN VENTURES LLC, ITS MEMBERS, EMPLOYEES, AND PROVIDERS FROM ANY CLAIM, LIABILITY, OR DAMAGE ARISING FROM YOUR USE OF ARC OR ANY WORKOUT YOU PERFORM BASED ON INFORMATION FROM ARC. By tapping “I understand and accept” in the app, or by continuing to use the app, you confirm you have read, understood, and agreed to this waiver.

AI features

Arc uses third-party AI providers (currently Google Gemini and Anthropic Claude) to power features like workout import, AI fill, plan generation, and the Arc Coach. When you use these features, the relevant inputs (such as pasted workout text, exercise names, or coach messages) are sent to the provider for processing.

We may store these inputs and the corresponding AI responses to monitor quality, debug issues, and improve the service over time. You can disable this collection at any time in iOS Settings → Data & Privacy. Opting out stops new collection going forward; previously stored entries are retained for up to 90 days and then deleted.

AI output is provided as-is and may contain errors. Always use your own judgment. Arc is not a medical or fitness professional. See also our privacy policy.

Intellectual property

Arc, its design, its software, and its content are owned by Crown Haven Ventures LLC and protected by copyright and trademark law. The Arc name and logo are our marks; you may not use them without our written permission. Your workout data belongs to you.

We grant you a personal, non-exclusive, non-transferable, revocable license to use Arc for your own non-commercial training. That license ends when these terms do.

Disclaimer of warranties

ARC IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT ARC WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR MEET YOUR SPECIFIC REQUIREMENTS.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CROWN HAVEN VENTURES LLC AND ITS PROVIDERS WILL NOT BE LIABLE FOR ANY LOST PROFITS, LOST DATA, OR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING FROM OR RELATED TO THESE TERMS OR YOUR USE OF, OR INABILITY TO USE, ARC.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING UNDER THESE TERMS IS CAPPED AT THE GREATER OF FIFTY DOLLARS ($50 USD) AND THE AMOUNT YOU PAID US IN THE SIX MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. HAVING MORE THAN ONE CLAIM DOES NOT RAISE THIS CAP.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so parts of this section may not apply to you. Nothing in these terms limits liability that cannot be limited under applicable law.

Indemnification

You agree to defend, indemnify, and hold harmless Crown Haven Ventures LLC and its members, employees, and agents from any claim, and from reasonable costs and attorneys’ fees, arising out of your use of Arc, your violation of these terms, or your violation of any law. We may take over the defense of any such claim at your expense, and you agree to cooperate. You may not settle a claim covered by this section without our written consent. We will make reasonable efforts to tell you promptly about any claim we learn of.

Termination

These terms stay in effect while you use Arc. You may stop at any time by deleting your account. We may suspend or terminate your access, including deleting your account, if we believe you have violated these terms or if we need to for legal or security reasons. We are not liable to you for a termination made on those grounds.

The following survive termination: intellectual property, disclaimer of warranties, limitation of liability, indemnification, assumption of risk and liability waiver, governing law, and general.

Governing law and venue

These terms, and any dispute arising out of or related to them or to Arc, are governed by the laws of the State of California, without regard to its conflict-of-law rules. You and Crown Haven Ventures LLC consent to the exclusive jurisdiction and venue of the state and federal courts in San Francisco County, California. Either party may still bring an action in any court of competent jurisdiction for injunctive relief to protect its intellectual property, and either party may bring an individual claim in small claims court if it qualifies.

Notice to California consumers

Under California Civil Code Section 1789.3, California users are entitled to this notice. The provider of Arc is Crown Haven Ventures LLC, 400 Page St #303, San Francisco, CA 94102. To file a complaint about Arc, or to ask for more information about using it, write to that address or email us at hello@arcfitness.app.

You may also contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs at 1625 N. Market Blvd., Suite N112, Sacramento, CA 95834, or by phone at (800) 952-5210. For California privacy rights, see our privacy policy.

Electronic communications

By using Arc you agree that we can communicate with you electronically, by email to the address on your account, by push notification, or by a notice posted in the app or on the site. Those electronic messages satisfy any legal requirement that a notice be in writing. You can unsubscribe from marketing and lifecycle email at any time using the link in every one of those emails; service messages such as sign-in codes and account or billing notices will still reach you.

General

  • Entire agreement: these terms, together with the privacy policy, are the whole agreement between you and us about Arc.
  • Severability: if any part of these terms is found unenforceable, it will be narrowed to the minimum extent needed to be enforceable, and the rest stays in effect.
  • No waiver: if we don’t enforce a provision, that isn’t a waiver of it.
  • Assignment: you may not assign these terms without our written consent. We may assign them, including to a successor in a merger or sale of the business.
  • Export: you agree not to use or export Arc in violation of U.S. export control laws.
  • Apple: Arc is distributed through the App Store. Apple is not a party to these terms and has no responsibility for Arc, but Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

Changes

We may update these terms. If the changes are material, we will tell you by email or by a notice in the app or on the site before they take effect. Continued use of Arc after that constitutes acceptance.
