Terms of Use

01About these terms

These terms govern your use of Impulse Health for iOS and related services provided by THE WORLD'S PHENOMENON PTE. LTD.. Please read them before using the app. If you do not agree, do not use the services.

These service terms supplement the license applicable to your App Store download. Where Apple’s Standard End User License Agreement applies, it governs the app license; these terms do not replace that agreement or Apple’s purchasing rules. Your statutory consumer rights remain unaffected.

02Wellness use and measurement limits

The app offers camera-based heart rate estimates, related wellness indicators, manually entered health records and educational content. It is not a medical device, clinical test, professional consultation or emergency alert system. HRV, stress, energy and similar indicators are estimates for general wellness, not diagnoses.

The phone camera does not measure blood pressure or blood oxygen in this app. Those features record values you obtain using separate appropriate equipment. Do not start, stop or change medication or treatment, or delay medical care, based on the app’s readings or content. Seek qualified medical advice for health decisions. In an emergency, contact local emergency services.

Movement, finger placement, pressure, lighting, temperature, circulation and device condition can affect camera estimates. Follow the on-screen instructions, and stop if the flash or device becomes hot or uncomfortable. We do not promise medical accuracy or a particular health outcome.

03Eligibility and device requirements

You must be at least 16, meet any higher minimum age required by local law, and have legal capacity or any required guardian authorization. The App Store content rating does not override these requirements.

Use a compatible iPhone and supported iOS version listed on the App Store. Camera measurements require a functioning supported camera/flash and camera permission. Online functions require internet access; your carrier’s charges may apply. Keep your device and service credentials secure and provide accurate information when needed.

04Permitted use and ownership

Subject to the applicable app license and these terms, you may use the app for personal, lawful purposes on compatible Apple devices you own or control, as allowed by Apple’s usage rules. The app, branding, designs and content belong to us or our licensors. You retain your rights in information you provide.

Do not redistribute or commercially exploit the app or its content without permission, bypass access restrictions, or reverse engineer it except where applicable law or an applicable open-source license permits. Rights not expressly granted are reserved.

05Subscriptions, trials and purchases

Some features require a paid subscription or other entitlement. The available product, price, currency, billing period, trial eligibility and benefits are shown before purchase in the app and Apple’s confirmation screen. Those purchase disclosures control your chosen offer; this page does not promise a fixed price or trial.

• Payment is charged through your Apple Account after you confirm the purchase.
• Auto-renewing subscriptions renew unless canceled before the applicable renewal deadline. To avoid renewal, cancel at least 24 hours before the current period ends. For a trial you do not wish to continue, cancel at least 24 hours before the trial ends.
• Manage or cancel in iOS Settings → your name → Subscriptions → Impulse. The Apple subscription screen shows the applicable renewal or expiry status.
• Deleting the app, requesting data deletion or stopping use does not cancel a subscription. Trial access may end when canceled, as shown by Apple.
• Use Restore on the app’s purchase screen with the Apple Account used for the original purchase to restore eligible purchases.
• Refund requests for Apple-billed purchases are handled through Apple under its rules and applicable consumer law. We cannot guarantee Apple will approve a refund.

Any price change is subject to Apple’s notice and consent requirements and applicable law. Redeemed promotional access follows the terms stated for that promotion; it does not cancel an existing Apple subscription.

06Your records and privacy

You are responsible for the accuracy of manually entered records and for keeping any copies you need. Local measurement history may be lost when the app or device data is deleted or the device is replaced; paid access restoration does not restore measurement history. We do not promise continuous backup or cloud recovery of local records.

The Privacy Policy explains profile uploads, local records, technical data, analytics and your choices. Do not submit another person’s sensitive information without a valid legal basis. A privacy permission is separate from acceptance of these terms.

07Responsible use

Do not use the services unlawfully, infringe others’ rights, introduce malicious code, disrupt the app or servers, access data without authorization, abuse support channels or fraudulently obtain purchases or promotional benefits. Do not present app estimates as clinically certified measurements.

Feedback you send may be used to respond to you and improve the app. Sending feedback does not transfer ownership of your personal records or grant us permission to publish your sensitive information.

08Third-party services and Apple

The app may display third-party ads or link to external educational material. External services have their own terms and privacy practices; an ad or link is not our endorsement or a medical recommendation.

We provide support for our app. Apple is not responsible for providing app maintenance or technical support on our behalf. Apple’s role in distribution, payments and the app license remains governed by its applicable agreements. Contact us for app issues and Apple for Apple-billed payment or account issues.

09Availability and suspension

Features may change and may be unavailable during maintenance, outages or circumstances beyond our reasonable control. We may restrict access where reasonably necessary to address unlawful use, a material breach or a security risk, giving notice and an opportunity to resolve the issue when appropriate.

If we materially reduce or discontinue a paid service, we will provide notice and any remedy required by applicable law and the relevant purchase terms. This section does not authorize us to keep payments where a refund or other remedy is legally required.

10Warranties and responsibility

To the extent allowed by law, the service is provided on an “as available” basis without a promise of uninterrupted operation, error-free content or fitness for a particular medical purpose. We are not responsible for losses caused by inaccurate information you enter, misuse contrary to instructions or independent third-party services, except to the extent applicable law makes us responsible.

Nothing in these terms excludes or limits liability that cannot lawfully be excluded, including applicable consumer guarantees, fraud, deliberate misconduct, or death/personal injury caused by negligence where such exclusion is prohibited. Any permitted limitation applies only to the extent allowed by the law governing your claim.

11Changes and ending use

We may revise these terms and update the date above. Material changes will be notified appropriately; we obtain agreement where required by law. You may stop using and delete the app at any time. Cancel Apple subscriptions separately to stop future renewal charges.

Ending use does not remove payment obligations already incurred, rights arising before termination, or provisions that reasonably need to survive, such as ownership and dispute provisions. Data deletion follows the Privacy Policy.

12Disputes and interpretation

Please contact us first so we can try to resolve a concern. This does not restrict your right to contact a regulator or bring a claim before a competent court. Applicable mandatory law, including consumer protections in your place of residence, remains in force. These terms do not impose mandatory arbitration or waive class-action rights.

If a provision is unenforceable, the remaining provisions continue to apply to the extent lawful. A failure to enforce a provision is not a waiver. The English and Simplified Chinese versions are intended to be equivalent; any discrepancy will be resolved under applicable law, without reducing mandatory consumer protections.
