1. General Terms
These Terms of Use govern the use of Puls: Heart Rate Check & Tracker.
By using the app, the user confirms that they have read, understood, and agreed to these Terms of Use.
If the user does not agree to these Terms, they must stop using the app.
2. Purpose of the App
The app is intended for informational, wellness, and educational purposes. It may provide users with:
- heart rate estimation based on camera/PPG signals;
- HRV-related metrics;
- derived wellness-related indicators;
- manual tracking tools for certain values;
- measurement history and related features.
The app is not a medical device unless expressly stated otherwise by the service operator in official documentation.
The app is not intended:
- to diagnose any condition;
- to prevent, monitor, or treat disease in the medical sense;
- to replace professional medical advice, diagnosis, or care;
- to be used in emergency or life-threatening situations.
If a user feels unwell, has symptoms, experiences pain, suspects a heart-related or other health issue, or requires medical attention, they should seek assistance from a qualified medical professional and should not rely solely on the app.
3. Wellness and Educational Disclaimer
All results, scores, estimates, derived indicators, interpretations, and explanatory content provided in the app are for informational, wellness, and educational purposes only.
The values shown in the app may depend on many factors, including:
- signal quality,
- lighting conditions,
- finger placement on the camera,
- user movement,
- individual physiological differences,
- device characteristics,
- operating system version,
- and algorithm implementation details.
As a result, app outputs may be approximate and should not be treated as a medical conclusion, diagnosis, or treatment recommendation.
Your device's camera cannot provide medical-grade measurements and should not be relied upon as a foundation for medical conclusions regarding your health condition. Consult your healthcare provider (with medical facility equipment) before making any health-related conclusions.
4. User Responsibility
The user is solely responsible for:
- how they use the app;
- what data they enter manually;
- how they interpret any values shown;
- and any decisions they make based on information provided by the app.
The user agrees not to use the app for purposes for which it is not intended, including as a substitute for professional medical diagnosis, medical monitoring, or emergency care.
5. Accuracy and Availability
We strive to keep the app functional and useful. However, we do not guarantee that:
- the app will operate without errors, interruptions, or delays;
- any metric, calculation, estimate, score, or result will be accurate, complete, or fit for a particular purpose;
- the app will be available at all times or in an unchanged form;
- any specific feature will remain available permanently.
We may modify, update, restrict, suspend, or discontinue parts of the app at any time for technical, product, legal, operational, commercial, or other reasons.
6. Paid Features, Subscriptions, and Purchases
The app may offer paid features, subscriptions, trial periods, automatically renewing plans, or other forms of access to additional functionality.
At this time, the subscription model is expected to be handled through Apple where applicable. Subscription details may include subscription type, billing period, trial availability, automatic renewal, cancellation terms, and access conditions for premium features.
Final subscription details may be presented in the app, on the purchase screen, or through the applicable app store at the time of purchase.
Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless auto-renewal is turned off at least 24 hours before the end of the current billing period. You may manage and cancel subscriptions through your Apple ID account settings.
If a free trial is offered, it will automatically convert to a paid subscription at the end of the trial period unless cancelled at least 24 hours before the trial ends.
Uninstalling the App does not automatically cancel your subscription. You must cancel through your Apple ID account settings.
7. Subscription Cancellation and Refunds
If a subscription is purchased through Apple App Store, billing, renewal, cancellation, and refund handling may be governed by Apple’s rules and the user’s Apple account settings.
Users may generally manage and cancel subscriptions through their Apple account settings.
To the extent permitted by applicable law, we do not control Apple’s billing systems or Apple’s refund decisions.
This section may be updated once the final payment model is confirmed.

9. User Data and Local Storage
Users retain control over the data they manually enter and the records stored locally in the app on their device, to the extent allowed by the app’s technical design and applicable law.
Because the current architecture relies primarily on local storage, users are responsible for the security of their device, deletion of locally stored information, and the consequences of deleting the app or device data.
