Last updated: June 15, 2026
1. Acceptance of these terms
These Terms of Use (“Terms”) form a legal agreement between you and Axiosware (“we,” “our,” or “us”) governing your use of the HeartBalance mobile application and related services (the “Service”). By downloading, accessing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
2. Eligibility
You must be at least 18 years old, or the age of majority in your jurisdiction, to use the Service. By using HeartBalance, you represent that you meet this requirement.
3. The Service
HeartBalance helps you measure your heart rate using your iPhone’s camera, track steps and activity, and view a personalized daily Health Score, stress and energy insights, and weekly trends. The Service can integrate with Apple Health and Apple Watch where you grant permission. Features may change, improve, or be discontinued over time.
4. Medical disclaimer
HeartBalance is not a medical device and does not provide medical advice.
The app is intended for general wellness and informational purposes only. Heart-rate and related measurements, including camera-based (photoplethysmography) readings, are estimates and may be inaccurate. They are not a substitute for professional medical evaluation, diagnosis, or treatment.
Always seek the advice of a qualified healthcare provider with any questions about your health. Never disregard professional medical advice or delay seeking it because of something you saw in the app. If you think you may be having a medical emergency, call your local emergency number immediately.
5. Accounts
You can sign in using Sign in with Apple or Google Sign-In. You are responsible for activity that occurs under your account and for keeping your sign-in method secure. You may delete your account at any time from within the app.
6. Subscriptions & billing
HeartBalance is free to download and includes free features, such as camera-based heart-rate measurement. Premium features, including detailed Insights and Trends, require an auto-renewing subscription. Subscriptions are offered as a monthly and an annual plan, each with a 7-day free trial for new subscribers. Current pricing is shown in the app and on the App Store before you confirm a purchase.
- Payment is charged to your Apple ID account upon confirmation of purchase.
- Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
- Your account is charged for renewal within 24 hours before the end of the current period, at the price for your selected plan.
- You can manage or cancel your subscription, and turn off auto-renew, in your Apple ID account settings in the App Store after purchase.
- You can restore a previous purchase from within the app (for example, on a new device).
- Current pricing is shown in the app and on the App Store. Any unused portion of a free trial, where offered, is forfeited when you purchase a subscription.
All purchases are final except as required by law. Refund requests are handled by Apple through the App Store, in accordance with Apple’s policies.
7. Acceptable use
You agree not to:
- Reverse engineer, decompile, or attempt to extract the source code of the Service, except where permitted by law;

9. Third-party services
The Service relies on third-party providers, including Apple (HealthKit, App Store, StoreKit) and other service providers for authentication, cloud storage and sync, push notifications, and subscription management. Your use of those services is also subject to their respective terms and privacy policies.
10. Disclaimer of warranties
The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or accurate.
