01About this policy

This Privacy Policy applies to Impulse for Android, package com.heartwellness.app (the “app”), provided by THE WORLD'S PHENOMENON PTE.LTD. (“we”, “us” or “our”). It explains the information the app accesses, uses, stores and shares, and how to contact us about privacy.

Impulse offers camera-based pulse estimates, related wellness indicators, measurement history, a personal profile, wellness articles and quizzes, and optional local reminders. This policy describes these Android features. It does not describe a separate iOS app or features that have not been introduced.

02Information we use and why

Camera images and pulse signals

When you start a measurement and grant camera access, the app processes camera frames and changes in light from your fingertip, using the flash where available, to estimate your pulse and related metrics. Images are processed temporarily on the device, are not saved as photos or videos, and are not uploaded to us.

Saved health measurements

When you choose to save a measurement, the app stores its time, estimated heart rate, beat-to-beat intervals, derived heart-rate variability (HRV) metrics, and calculated heart score or score level. These records support your history, charts and comparisons. They are stored locally in the app’s private database, not on a server operated by us.

Profile information you enter

Your sex selection, age, height, weight, preferred units and, where applicable, a separate reference selection for heart-score calculations are saved on your device. The app uses these details to personalize the interface and wellness calculations. There is no app account registration, email sign-up or profile-photo upload.

Quiz answers

Answers to wellness and self-assessment questions, which may include sensitive wellbeing information, are used locally to calculate and display results during the session. The app does not upload your answers to us or maintain an account-based quiz history.

Preferences and device settings

The app uses your language, local time and time zone, camera availability, permission status, and reminder preferences to display content and schedule notifications. It does not request access to your contacts, microphone, photo library, precise or approximate device location, or Health Connect records.

Google Play information

The app includes Google Play Billing to obtain subscription-product information and observe purchase information when products are configured. Related processing by Google is described in Section 4. The app does not receive your full payment-card details.

Information you send us directly

If you email our privacy contact, we receive your email address, the content of your request and any attachments you choose to send. We use them to answer you and handle the request. Please include only what is necessary. The feedback form in this Android version is not connected to a submission service and does not send the entered message to us.

The app does not include advertising or a separate user-behavior analytics service. We do not sell your personal information or use your health records for advertising.

03Permissions and device access

• Camera: requested to perform a pulse measurement. If you decline or revoke it, camera-based measurement is unavailable.
• Notifications: used for optional heart-rate reminders. On Android versions that require permission, you can allow or decline it, and you can disable reminders or notifications later.
• Startup and time-change events: used to reschedule enabled local reminders after a restart or a change to the device’s time or time zone.
• Internet, network status and Google Play Billing: support the included Google Play integration and its service communications. These permissions do not mean that your camera frames or saved health history are uploaded to us.

You can manage runtime permissions in Android Settings → Apps → Impulse → Permissions, and notification access under Notifications. Menu names may vary by device.

04Sharing and third-party services

Local health information

The app does not send your camera frames, saved measurements, profile or quiz answers to a developer-operated server or to advertising services. We cannot retrieve this local health history remotely.

Google Play and Google services

When available and configured, the Premium screen communicates with Google Play to request product, pricing and purchase-status information. The Android version covered by this policy does not complete checkout or grant a paid entitlement from those queries.

Google may process information about your device and app, identifiers, IP address, service activity, and diagnostic information when its services communicate with Google. Google manages its own account and purchase records. This processing supports its services, reliability and security and is governed by Google’s Privacy Policy. It is separate from the health records stored locally by Impulse.

Links and sharing you initiate

If you open an article source, Google Play listing or social-media link, your browser or another app connects to the destination. The destination can receive network and device information and uses its own privacy policy. “Share App” shares a store-link message, not your measurement history. External destinations can process information in other countries under their own policies.

Privacy enquiries

Email communications are handled through email service providers to deliver and respond to your request. Information you send us may also be disclosed where we are legally required to do so. This does not give us access to health records held only on your device.

05How long information is kept and how to delete it

Camera images: used during measurement and not retained as image or video files. Saved results contain numerical measurements and derived metrics, not the original camera images.

Profile, preferences and saved measurements: remain in the app’s private storage until you change the relevant profile or setting, clear app storage, or uninstall the app. Saved measurements have no automatic expiry.

Delete data on your device

1. Open Android Settings → Apps → Impulse.
2. Open Storage or Storage & cache.
3. Choose Clear storage or Clear data. Clearing only the cache does not delete all saved records.

You can also uninstall Impulse to remove its app-private data from the device. Clearing storage removes all local profile data, preferences and saved measurements. The app does not currently offer individual-record deletion or history export. There is no account-deletion screen because the app has no app account.

Backups and transfers: the app does not provide cloud backup and disables standard Android app backup. Device-to-device transfer behavior can vary by Android version and manufacturer. Copies previously transferred to another device must be removed there as well.

Privacy correspondence: kept for as long as needed to resolve the request and meet applicable legal obligations, then deleted or anonymized when there is no remaining reason to retain it. Google and external services apply their own retention and deletion rules; clearing Impulse’s storage does not delete their records.

06How information is protected

Impulse stores saved measurements in an app-private database and profile information in app-private preferences. Android’s application sandbox restricts ordinary access by other apps. The health database does not add its own separate encryption layer.

Security also depends on your device and operating system. Protect your device with a screen lock and current security updates. No storage or transmission method offers absolute security. Information handled by Google or an external destination is protected under that provider’s own procedures.

07Your choices and privacy rights

You can edit your profile, stop a measurement, decline or revoke camera permission, turn off reminders, manage notifications, and remove local information as described above.

Depending on the laws that apply to you, you may have rights to access, correct or delete personal information, restrict or object to processing, obtain a portable copy where applicable, withdraw consent where processing relies on consent, or complain to a competent privacy authority. Contact us using Section 11 to make an enquiry or exercise an applicable right.

We may request only the information needed to verify and respond to a request. Since we do not hold a server copy of your local health records, we cannot retrieve, export or delete those records remotely; you can control them on your device.

08Children’s privacy

Impulse is not designed for children, and its wellness estimates are not clinically validated for children. Its profile age selector is not an age-verification system. A parent or guardian with a concern about a child’s use or information can contact us and can remove locally stored information using the deletion steps above.

09About health information

Impulse is intended for general wellness and informational use. It is not a medical device and does not diagnose, treat, cure or prevent a medical condition. Pulse estimates, HRV metrics, heart scores, articles and quiz results are not a substitute for professional medical advice. Consult a qualified healthcare professional for medical decisions or health concerns.

10Changes to this policy

We will update this policy when our data practices or applicable requirements change and revise the “Last updated” date. Where required, we will provide an additional notice and obtain any necessary consent before new processing begins.

11Contact us

For privacy questions or requests relating to Impulse, contact the publisher below. Please identify the app and describe your request; you do not need to send your health history unless it is necessary for your enquiry.

01本政策的适用范围

本隐私政策适用于由 THE WORLD'S PHENOMENON PTE.LTD.（以下简称“我们”）提供的 Impulse Android 应用（以下简称“本应用”），包名为 com.heartwellness.app。本政策说明应用访问、使用、保存和共享的信息，以及您如何就隐私问题联系我们。

Impulse 提供摄像头脉搏估算、相关健康参考指标、测量历史、个人资料、健康文章与测试，以及可选的本地提醒。本政策描述这些 Android 功能，不适用于独立的 iOS 应用或尚未推出的功能。

02信息类型与使用目的

摄像头画面与脉搏信号

您开始测量并授予摄像头权限后，应用会处理摄像头画面和指尖光线变化，在设备支持时使用闪光灯，估算脉搏及相关指标。画面仅在本机临时处理，不会保存为照片或视频，也不会上传给我们。

保存的健康测量记录

当您选择保存测量结果时，应用会保存测量时间、估算心率、心跳间期、由此计算的心率变异性（HRV）指标，以及心脏评分或评分等级。这些记录用于历史记录、图表和对比，保存在本机应用私有数据库中，不保存在我们运营的服务器上。

您填写的个人资料

您的性别选择、年龄、身高、体重、单位偏好，以及适用时用于心脏评分计算的独立参考档位，会保存在本机，用于个性化界面和健康参考计算。应用没有应用账户注册、邮箱注册或头像上传功能。

测试答案

健康与自我评估问题的答案可能包含敏感的身心健康信息。应用在本机使用这些答案，计算并显示当前测试结果，不会将答案上传给我们，也不维护基于账户的测试历史。

偏好与设备设置

应用使用语言、本地时间与时区、摄像头可用状态、权限状态及提醒偏好，以显示内容和安排通知。应用不申请访问通讯录、麦克风、相册、设备精确或大致位置，以及 Health Connect 健康记录的权限。

Google Play 信息

应用包含 Google Play Billing，可在已配置商品时获取订阅商品信息及查询购买信息。Google 的相关处理方式见第 4 节。应用不会接收您的完整银行卡信息。

您主动发送给我们的信息

如果您向隐私联系邮箱发信，我们会收到您的邮箱地址、请求内容及您主动提供的附件，用于回复和处理请求。请仅提供必要信息。本 Android 版本内的反馈表单尚未连接提交服务，不会将填写的消息发送给我们。

应用没有接入广告或独立的用户行为分析服务。我们不出售您的个人信息，也不将您的健康记录用于广告。

03权限与设备访问

• 摄像头：用于脉搏测量。拒绝或撤回权限后，无法使用摄像头测量功能。
• 通知：用于可选的心率提醒。在需要通知授权的 Android 版本上，您可以允许或拒绝，也可以之后关闭提醒或通知。
• 开机及时间变化事件：用于在设备重启、时间或时区变化后，重新安排您已开启的本地提醒。
• 网络、网络状态与 Google Play Billing：用于应用所含的 Google Play 集成及相关服务通信。这些权限不表示您的摄像头画面或已保存的健康历史会上传给我们。

您可以通过 Android“设置 → 应用 → Impulse → 权限”管理运行时权限，并在“通知”设置中管理通知。不同设备的菜单名称可能有所不同。

04共享与第三方服务

本机健康信息

应用不会将摄像头画面、已保存的测量记录、个人资料或测试答案发送至开发者运营的服务器或广告服务。我们无法远程读取这些本机健康历史。

Google Play 与 Google 服务

服务可用且商品已配置时，会员页面会与 Google Play 通信，查询商品、价格和购买状态信息。本政策所描述的 Android 版本不会通过这些查询完成付款或授予付费权益。

Google 服务与其服务器通信时，Google 可能处理设备及应用信息、标识符、IP 地址、服务使用活动和诊断信息。Google 自行管理其账户及购买记录。这些处理用于提供服务、保障可靠性和安全，并适用 Google 隐私政策，与 Impulse 保存在本机的健康记录相区分。

您主动打开的链接与分享

您打开文章来源、Google Play 商店页面或社交媒体链接时，浏览器或其他应用会连接目标服务。目标服务可能接收网络及设备信息，并适用其自身的隐私政策。“分享应用”分享的是商店链接文字，不是您的测量历史。外部服务可能依据其政策在其他国家或地区处理信息。

隐私咨询

邮件通信通过邮件服务提供方传递，用于接收和回复您的请求。在法律要求的情况下，我们也可能披露您发送给我们的信息。这不代表我们能够读取仅保存在您设备上的健康记录。

05保存期限与删除方式

摄像头画面：仅在测量期间使用，不作为图片或视频文件保留。保存的结果包含数值测量及计算指标，不包含原始摄像头画面。

个人资料、偏好及保存的测量记录：保存在应用私有存储中，直至您修改相应资料或设置、清除应用存储或卸载应用。已保存的测量记录没有自动到期删除期限。

删除设备上的数据

1. 打开 Android “设置 → 应用 → Impulse”。
2. 进入“存储”或“存储与缓存”。
3. 选择“清除存储”或“清除数据”。仅清除缓存不会删除全部已保存记录。

您也可以卸载 Impulse，以移除该设备上的应用私有数据。清除存储会删除本机全部个人资料、偏好和已保存的测量记录。应用目前没有单条历史删除或历史导出功能；由于没有应用账户，也没有账户注销页面。

备份与设备迁移：应用不提供云备份，并关闭标准 Android 应用备份。设备之间的数据迁移行为可能因 Android 版本和设备厂商而异；已经迁移到其他设备的副本，需要在相应设备上另行删除。

隐私联系记录：仅在解决请求及履行适用法律义务所需的期间内保存，在没有其他保存理由后删除或匿名化。Google 和外部服务适用各自的保存及删除规则，清除 Impulse 存储不会删除其记录。

06信息安全

Impulse 将测量记录保存在应用私有数据库中，将个人资料保存在应用私有偏好设置中。Android 应用沙盒限制其他普通应用直接访问这些数据。健康数据库没有额外的应用层独立加密。

数据安全也取决于设备与操作系统。请使用锁屏并及时安装系统安全更新。任何存储或传输方式都无法保证绝对安全。Google 或外部目标服务处理的信息，受相应服务提供方自身安全措施的保护。

07您的选择与隐私权利

您可以修改个人资料、停止测量、拒绝或撤回摄像头权限、关闭提醒、管理通知，并按上述方式删除本机信息。

根据适用法律，您可能享有访问、更正或删除个人信息、限制或反对处理、在适用时获取可携带副本、撤回基于同意的处理授权，以及向有权的隐私监管机构投诉等权利。您可以通过第 11 节的联系方式咨询或行使适用权利。

我们可能仅要求提供核实和处理请求所必需的信息。由于我们没有您的本机健康记录的服务器副本，无法远程读取、导出或删除这些记录；您可以在自己的设备上管理它们。

08儿童隐私

Impulse 并非为儿童设计，其健康估算未经针对儿童的临床验证。个人资料中的年龄选择器并非年龄验证系统。监护人如对儿童使用应用或相关信息有疑问，可以联系我们，并可按照上述删除步骤清除本机信息。

09健康信息说明

Impulse 仅用于一般健康管理和信息参考，不是医疗器械，不用于诊断、治疗、治愈或预防疾病。脉搏估算、HRV 指标、心脏评分、文章及测试结果均不能替代专业医疗建议。作出医疗决定或存在健康疑虑时，请咨询具备资质的医疗专业人员。

10政策更新

当数据处理方式或适用要求变化时，我们会更新本政策及页面上的“最后更新”日期。如有要求，我们会在开展新的处理活动前另行告知，并取得必要同意。

11联系我们
