Privacy Policy

Effective date: June 23, 2026

Beating (“the App”, “we”) is a heart-rate–focused health data visualization tool. We take your privacy — especially your health data — seriously. This policy explains what we collect, how we use and store it, and the rights you have.

1. Information We Collect

Health data (read via Apple HealthKit, with your permission): heart rate, resting heart rate, heart rate variability (HRV), high/low heart-rate events, steps, walking & running distance, active energy, stand time, sleep analysis, body mass / BMI, VO₂max, and workouts. The App only reads this data; it never writes data to HealthKit.

Location (optional, while in use): only when you actively enable the Weather feature, to fetch the current temperature for your city. We do not continuously track or store your precise location history.

Sync & account identifiers: the App generates a random sync key and device token on your device to securely sync your data across your devices and to power family/friend groups. We do not collect your name, phone number, or precise identity (other than a nickname you may set yourself).

Diagnostics: the App keeps a small amount of sync-status information locally for troubleshooting; this is not uploaded by default.

2. How We Use Information

To present your heart-rate trends, time-segment analysis, and health overview;
To sync data across your devices and among members of family/friend groups you choose to join;
To provide supplementary features such as weather.

We never: use your health data for advertising, marketing, or use-based data mining; and we never sell your health data or provide it to data brokers, ad networks, or third parties for such purposes.

3. HealthKit Data — Specific Notice

As required by Apple, data obtained from HealthKit is used solely to provide you with health and fitness services. It is not used for advertising or similar services, and is not shared with any third party that does not help you manage your health or fitness.

4. Storage & Sync

On device: your data is primarily stored on your device.
Beating Cloud (api.15dian.com): to enable cross-device sync and family sharing, heart-rate summaries, analysis data, and custom periods are transmitted over HTTPS, scoped by your sync key, and stored on our servers.
iCloud (optional): if you choose iCloud sync, some data syncs through your own Apple iCloud account.
Family/friend groups: when you enable sharing, your daily health overview is shared with members of your group. You can turn off sharing or leave a group at any time.

5. Data Sharing

Other than members of family/friend groups you actively join, we do not share your personal health data with third parties. We use Apple system services (HealthKit, WeatherKit, and optional CloudKit), which are governed by Apple’s own privacy policy.

6. Your Rights

Delete account: in Settings → Account & Legal → Delete Account, you can permanently delete your account and all cloud and on-device data.
Turn off sharing: disable health-data sharing or leave a group at any time in Family settings.
Revoke access: revoke the App’s HealthKit access anytime in iOS Settings → Privacy & Security → Health.

7. Security

Sync keys and device tokens are stored in the system Keychain; all communication with our servers uses HTTPS. Please note that no method of transmission or storage is 100% secure.

8. Children’s Privacy

The App is not directed to children under 13, and we do not knowingly collect personal information from children.

9. Changes to This Policy

We may update this policy from time to time. Material changes will be indicated by updating the “Effective date” above or via an in-app notice.

隐私政策

Beating（“本应用”“我们”）是一款以心率为核心的健康数据可视化工具。我们非常重视你的隐私，尤其是健康数据。本政策说明我们收集哪些信息、如何使用与存储，以及你拥有的权利。

1. 我们收集的信息

健康数据（经你授权，通过 Apple HealthKit 读取）：心率、静息心率、心率变异性（HRV）、高/低心率事件、步数、步行与跑步距离、活动能量、站立时间、睡眠分析、体重 / BMI、最大摄氧量（VO₂max）以及体能训练记录。本应用仅读取这些数据，不会向 HealthKit 写入数据。

位置（可选，使用期间）：仅当你主动开启“天气”功能时，用于获取你所在城市的当前气温。我们不会持续追踪或存储你的精确位置轨迹。

同步与账户标识：本应用会在你的设备上生成一个随机同步密钥与设备令牌，用于在你的多台设备间安全同步数据、以及家庭/好友组功能。我们不会收集你的姓名、电话号码或精确身份信息（你可自行设置的昵称除外）。

诊断信息：App 本地会记录少量同步状态用于排错，这些信息默认不会上传。

2. 我们如何使用信息

为你呈现心率趋势、时段分析与健康概览；
在你的设备之间，以及你选择加入的家庭/好友组成员之间同步数据；
提供天气等辅助展示功能。

我们绝不会：将你的健康数据用于广告、营销或基于使用行为的数据挖掘；也绝不会出售你的健康数据，或将其提供给数据中介、广告平台或第三方用于上述目的。

3. HealthKit 数据的特别声明

4. 数据的存储与同步

设备本地：数据主要保存在你的设备上。
Beating 云端（api.15dian.com）：为实现跨设备同步与家庭共享，心率汇总、分析数据、自定义时段等会按你的同步密钥加密传输（HTTPS）并存储在我们的服务器上。
iCloud（可选）：若你选择 iCloud 同步方式，部分数据会通过你自己的 Apple iCloud 账户同步。
家庭/好友组：当你开启共享后，你的每日健康概览会与同组成员共享；你可随时关闭共享或退出群组。

5. 数据共享

除你主动加入的家庭/好友组成员外，我们不会与第三方共享你的个人健康数据。我们使用 Apple 提供的系统服务（HealthKit、WeatherKit、可选的 CloudKit）来实现相应功能，这些服务受 Apple 自身隐私政策约束。

6. 你的权利

删除账户：在“设置 → 账户与法律 → 删除账户”中，可永久删除你的账户及云端与本机的全部数据。
关闭共享：可随时在家庭设置中关闭健康数据共享或退出群组。
撤销授权：可在 iOS“设置 → 隐私与安全性 → 健康”中随时撤销本应用的 HealthKit 访问权限。

7. 数据安全

同步密钥与设备令牌保存在系统 Keychain 中；所有与服务器的通信均通过 HTTPS 加密传输。请注意，没有任何一种网络传输或存储方式是 100% 绝对安全的。

8. 儿童隐私
