By downloading, installing, accessing, or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

Description of Service
Impello is a fitness training log that helps you record workout sessions, manage saved workouts, review your training history, track progress, use rest timers, sync account data across devices, and use companion features on Apple Watch.
User Accounts
- You may need an account to access certain features.
- You are responsible for maintaining the security of your account.
- You must provide accurate and current information.
- You must notify us promptly of any unauthorized access to your account.
- Passwordless login still requires you to keep your email and account access secure.
Health and Fitness Disclaimer
Impello is not a medical device, healthcare provider, personal trainer, emergency service, or substitute for professional advice, diagnosis, or treatment. Information shown in Impello, including heart rate, workout history, progress metrics, and training data, is for general fitness tracking only.
Do not rely on Impello for diagnosis, treatment, injury prevention, emergency response, or medical decisions. Consult a qualified healthcare provider before beginning or changing an exercise program where appropriate.
User Assumes Training Risk
You are solely responsible for your exercise choices, training intensity, technique, equipment use, and physical condition. Exercise involves risk, including the risk of injury, illness, or death.
You should stop exercising immediately and seek qualified help if you experience pain, dizziness, shortness of breath, or other concerning symptoms.
Apple Watch, Apple Health, and Device Data
Apple Watch and Apple Health features depend on device compatibility, your permissions, Apple systems, sensors, connectivity, battery status, operating system behavior, and service availability. Heart rate and other device-based fitness data may be inaccurate, delayed, incomplete, or unavailable.
You can manage Apple Health permissions at any time in your device settings. Impello is not responsible for interruptions, delays, or inaccuracies caused by device, platform, or connectivity limitations.
Subscriptions, Billing, and Refunds
Certain features may require a paid subscription. Pricing, billing period, renewal terms, and cancellation details will be shown to you before purchase.
Purchases made through Apple's App Store are processed by Apple and are subject to Apple's terms, billing rules, and refund policies. Impello does not control Apple's refund decisions. You can manage or cancel subscriptions through your App Store account settings.
Free Access, Early Access, Promotional Access, and Founding Terms
Impello may, from time to time, offer free access, early access, promotional access, founding-user terms, or other limited offers. Any such offer applies only as described when it is presented to you.
Unless expressly stated otherwise, Impello may modify, limit, or discontinue promotional or early-access programs prospectively.
User Content and Workout Data
You retain ownership of the workout data and content you submit to Impello. You grant Impello a limited, non-exclusive, worldwide license to host, store, process, display, transmit, and back up that data solely as necessary to provide, maintain, secure, support, and improve the Services.
You are responsible for the data you enter into the Services.
Data Availability and Sync
Impello does not guarantee that the Services will always be uninterrupted, error-free, or available. Impello does not guarantee that sync will always succeed or that data will never be lost. You are responsible for reviewing your logged data and maintaining separate records where needed.
Acceptable Use
You agree not to:
- Use the Services for any unlawful purpose or in violation of these Terms
- Interfere with or disrupt the integrity or performance of the Services
- Attempt to gain unauthorized access to the Services or related systems

Intellectual Property
Impello and its licensors own the app, design, branding, software, interfaces, graphics, text, and other content that is part of the Services. These materials are protected by intellectual property laws.
You may not copy, modify, distribute, sell, lease, sublicense, or create derivative works from the Services, except as expressly permitted by law or these Terms.
Third-Party Services and Platforms
The Services may rely on third parties, which may include Apple, the App Store, Apple Health, hosting providers, subscription providers, analytics and diagnostics providers, and infrastructure vendors. Impello is not responsible for third-party services. Your use of those services may be subject to their own terms.
App Store Terms
If you downloaded Impello through Apple's App Store, these Terms are between you and Impello, not Apple. Apple is not responsible for the Services or their maintenance or support, and is not responsible for any claims relating to the Services or warranties.
