terms of service
last updated: may 9, 2026
by using arc (“the app”), you agree to these terms. if you don’t agree, don’t use the app.
the service
arc is a fitness tracking app that lets you log workouts, track progress, and build exercise habits. we may update, modify, or discontinue features at any time.
your account
- you must provide a valid email address to create an account.
- you are responsible for all activity under your account.
- you may delete your account at any time from settings. deletion is immediate and permanent.
acceptable use
you agree not to:
- use the app for any unlawful purpose
- attempt to access other users’ data
- reverse engineer, decompile, or disassemble the app
- interfere with or disrupt the app’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 arc fitness, its operators, and its providers from any claim, liability, or damage arising from your use of the app or any workout you perform based on information from the app. 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, program 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
the app, its design, and its content are owned by arc fitness. your workout data belongs to you.
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, and non-infringement. we do not warrant that the app will be uninterrupted, error-free, or meet your specific requirements.
limitation of liability
to the maximum extent permitted by law, arc fitness shall not be liable for any indirect, incidental, or consequential damages arising from your use of the app.
changes
we may update these terms. continued use of the app after changes constitutes acceptance.
