Privacy Policy

Effective September 3, 2026

Effective date: September 3, 2026

WristBeat is a metronome application for iPhone and Apple Watch, developed by an independent individual developer identified as the provider or seller in the App Store listing ("we," "us," or "our"). This Privacy Policy covers the WristBeat app, this website, and support communications. The developer is responsible for personal information handled under this policy and acts as its controller where that concept applies. Contact: support@wristbeat.watchosapp.com.

1. Summary

WristBeat's core metronome and practice features work on your devices without an internet connection. iCloud sync, opening web pages, downloading or updating the App, purchases, and sending email involve online services. Device and band synchronization also use the relevant device connections.

  • We do not require you to create an account.
  • We do not include advertising, tracking pixels, or third-party analytics or crash-reporting SDKs in the App.
  • We do not sell your personal information or use it for targeted advertising.
  • Your metronome settings, rhythms, songs, setlists, practice history, and preferences are stored on your devices. When you enable iCloud sync, supported App data is also stored in your personal iCloud account. We do not operate a separate account or developer-hosted cloud-storage service for this content.
  • Apple Health integration, microphone features, and nearby band sync are under your control. Their data handling is explained in Section 2.
  • Support emails, Apple's services, and visits to this website may involve the limited information described below. We therefore do not claim that no information can ever reach us.

2. App Data, Synchronization, and Permissions

WristBeat may store information that you create or configure, including:

  • BPM, time signature, subdivision, accent, sound, visual, and haptic settings;
  • practice modes, timers, and musical practice session history;
  • songs, their sections, and setlists;
  • recordings you choose to make; and
  • app theme and other preferences.

This information is stored using Apple platform storage. We do not automatically receive it. It remains on your device until you change or delete it, remove the app, or erase the device. If you choose to send content in a support message, that copy is handled as support information.

iPhone and Apple Watch synchronization

When you use iPhone–Apple Watch synchronization, supported settings, playback information, and content are exchanged between your paired devices using Apple's device communication services. This exchange does not send that content to a developer-operated server. Nearby band synchronization is a separate feature described below.

Your device backup settings may cause Apple to retain copies of App data, including in iCloud Backup. Device backup is separate from an in-app cloud-sync feature. Deleting the App from one device does not necessarily delete a copy on another device or in a backup. Apple's handling of backup and device-service data is covered by Apple's Privacy Policy.

iCloud

WristBeat offers iCloud sync for metronome settings, songs, setlists, musical practice history, and preferences. When you enable it, these items are stored in your personal iCloud account so that they can be available on your other devices. Apple handles the storage and transfer under Apple's Privacy Policy. We do not receive your Apple Account credentials or retrieve your synced content on developer-operated servers.

You can turn sync off in the App's settings and manage stored App data through your device's iCloud settings. Turning sync off does not by itself erase data already stored in iCloud. Changes and deletions may propagate to other devices while sync is enabled. Musical practice history means your App practice records, not health or fitness measurements. WristBeat does not store HealthKit data or personal health information in iCloud, and does not upload microphone audio or recordings through its iCloud sync feature. Device backups remain governed by your separate Apple backup settings.

Apple Health (HealthKit)

WristBeat offers an optional Long Practice mode on Apple Watch. When you explicitly enable this mode, the App starts a system workout session through HealthKit to support the extended session while you practice, including when your wrist is lowered. Operation remains subject to Apple's system permissions, background limits, and power management; starting a session is not a guarantee of uninterrupted haptic output.

When this mode is active:

  • WristBeat does not read your health or fitness data, including heart rate or existing Apple Health records.
  • WristBeat does not save your practice as a workout or write health or fitness samples to Apple Health.
  • WristBeat does not upload, share, or otherwise transmit health-related data through this mode, and does not store it in iCloud.
  • The session starts only after you enable the mode and ends when you stop playback, the practice timer expires, or the system ends the session.

We do not use health data for advertising, marketing, profiling, or use-based data mining, and do not disclose health data to third parties. Starting a system workout session can affect watchOS's own activity tracking. Depending on your device settings and system behavior, Apple may record activity or reflect exercise time in Fitness or Health independently of WristBeat saving a workout. Those system records are managed by Apple; you can review and manage them in Apple's apps and settings.

You can use the core metronome without Long Practice mode. You can turn the mode off and manage any Health-related permissions through Apple's Health or device settings. The use of HealthKit does not make WristBeat a medical device or a therapeutic service.

Microphone and recordings

WristBeat requests microphone permission when you choose sound-based tempo detection or the practice recorder. Audio is processed on your device. Sound-based detection uses the audio to estimate tempo; recordings are saved locally only when you choose to record. WristBeat does not upload microphone audio or recordings to developer servers, iCloud sync, or nearby band-sync peers.

You can stop detection or recording in the App and revoke microphone permission in your device settings. Revoking access stops further microphone use but does not automatically delete recordings you already saved; you can delete those recordings in the App. If you separately choose to share a recording, for example in a support email, the selected recipient receives that copy. Device backups may contain saved recordings under your Apple backup settings. The ordinary metronome can be used without microphone access.

Bluetooth and nearby band connections

Band sync connects your device directly with nearby devices running WristBeat so musicians can share timing. The musical information exchanged consists of tempo, time signature, and timing or synchronization messages. The connection also uses the device-discovery information needed to find and connect to the participants. No audio, recordings, health data, or practice history is sent through band sync, and the exchange does not pass through developer-operated servers.

You choose when to join or start a shared session. You can leave or stop the session and manage Bluetooth or local-network permissions in your device settings. Participating devices receive the timing information you share; use the feature with people you trust. Connection quality and operating-system behavior can affect synchronization.

3. Information We Receive

Support communications

If you contact us, we receive the information you choose to include in your message, such as your email address, message contents, and attachments.

If you use a support email prepared by WristBeat, it may include technical details such as your country or region code, preferred language, operating-system version, app version, and Apple's identifier for vendor (IDFV), where available. You can review the message and choose whether to send it; information included in the message can be removed before sending. WristBeat does not transmit the prepared support message automatically. An identifier sent with your email can be associated with your email address, so this correspondence is not necessarily anonymous. Please do not include passwords, payment-card details, or health records in support messages.

We use support information only to respond to you, troubleshoot issues, protect the app, and improve WristBeat.

Information handled by Apple

Apple may process information when you download, purchase, install, update, or use WristBeat under its own terms and Privacy Policy. Depending on your device and privacy settings, Apple may make App Store metrics and diagnostic or crash reports available to us. App Store metrics may be aggregated, while individual diagnostic reports may contain device, operating-system, and technical crash information; we do not describe all reports as anonymous or aggregated. We use available information to understand reliability and fix problems, not to track you across apps or websites. Apple's analytics-sharing controls are available in your device's Privacy & Security settings.

Purchases

WristBeat is free to download and offers a one-time in-app purchase for paid features, not a recurring subscription. Apple processes App Store payments. We do not receive your payment-card details, Apple Account password, or payment credentials. Apple may provide sales and transaction information for administration and purchase support. If you send us a receipt, order reference, or purchase question, we handle it as support information. Purchase checks and restoration on your device use Apple's services; WristBeat does not operate a payment server.

Website visits and theme preference

When you visit this website, the hosting and delivery provider may process technical request information such as your IP address, browser or device information, requested page, and request time to deliver and secure the site. This is separate from local metronome use. Cloudflare's handling of information when serving this site is described in Cloudflare's Privacy Policy.

The website stores your chosen light or dark theme in your browser's local storage. The preference stays in that browser, is not used to identify you, and can be removed by clearing the site's browser data. We do not add advertising cookies, tracking pixels, or visitor-analytics scripts to these pages. Links to Apple or other external websites are governed by those providers' own policies when you visit them.

4. How We Use Information

We use information we receive only as necessary to:

  • provide customer support and respond to requests;
  • diagnose bugs and improve reliability;
  • maintain the security and integrity of WristBeat; and
  • comply with applicable law and enforce our legal rights.

Website request information is used to deliver pages, prevent abuse, and maintain service security. Information provided for purchase support is used to answer the request and meet any related legal obligations.

We do not use personal information for advertising, profiling, or data-broker activities.

On-device microphone processing, iCloud sync, and nearby timing exchange serve the features you choose to use, as described in Section 2. The general support and service-provider disclosures in this policy do not authorize uploading health data or microphone recordings through those features.

5. Sharing of Information

We do not sell or rent personal information, share it for cross-context behavioral advertising, or disclose it to data brokers. We may disclose information only:

  • to service providers that handle support communications, website delivery, or security on our behalf, subject to appropriate confidentiality and data-protection obligations;
  • when you direct or authorize the disclosure;
  • when reasonably necessary to comply with law, legal process, or a valid governmental request, or to protect users, our rights, or the security of WristBeat; or
  • as part of a merger, acquisition, reorganization, or transfer of the app, subject to this Privacy Policy and applicable law.

6. Retention and Deletion

Information stored locally is controlled by you. You can delete songs, setlists, practice records, and recordings using the App's controls, or remove local App data by deleting the App from the device concerned. Removing the App does not necessarily delete data in iCloud, on other devices, in Apple device backups, or previously shared with someone else. You can manage iCloud App data through Apple's settings; synchronized deletions may propagate to connected devices. Health and Fitness records generated independently by Apple are managed through Apple's apps and settings. Browser theme preferences can be removed by clearing this site's browser data.

Support communications and related diagnostic details are normally retained only for as long as needed to resolve the request and maintain a reasonable record of the resolution, and ordinarily no longer than 12 months after the support request is closed, unless a longer period is required by law, necessary to establish or defend legal claims, or requested by you.

Diagnostic information we retain is kept only as long as reasonably needed to investigate reliability issues or meet legal obligations. Website providers may retain request information under their service policies for delivery, security, and legal purposes; retention is not determined by the App's local-data settings.

You may request deletion of support information by emailing us at support@wristbeat.watchosapp.com. We may need enough information to locate and verify the relevant correspondence. We cannot directly delete information held independently by Apple or another provider, but will assist where applicable law requires and direct you to the relevant provider when appropriate.

7. Legal Bases for Processing

Where the law requires a legal basis, the basis depends on the purpose:

  • steps at your request or performance of an agreement when providing support relating to WristBeat;
  • our legitimate interests in responding to general inquiries, troubleshooting, and securing the App and website, where this basis is recognized and those interests are not overridden by your rights;
  • your consent when consent is required for an optional use of information; or
  • to comply with legal obligations.

You may withdraw consent at any time, but doing so does not affect processing already carried out lawfully.

8. International Processing

Support communications and website request information may be processed in countries other than the country where you live, including where the developer or service providers operate. Where required, we use legally recognized safeguards for international transfers, and you may contact us for information about applicable safeguards. Content that stays on your devices is not transferred to us. Data you choose to sync through iCloud is stored and transferred by Apple under its own policies, as is information processed independently through Apple's other services.

9. Your Privacy Rights

Depending on where you live, you may have rights to request access to, correction of, deletion of, restriction of, or a copy of personal information we hold about you, or to object to certain processing. You may also have the right to lodge a complaint with your local data-protection authority.

To make a request, contact support@wristbeat.watchosapp.com. We will respond within the period required by applicable law and request only information reasonably needed to verify and fulfill the request. Rights may be subject to legal exceptions. Because WristBeat does not operate user accounts and locally stored App data is not accessible to us, we cannot retrieve or delete that local data on your behalf. This does not remove your rights regarding support correspondence or other information we hold.

10. Children

WristBeat is a general-audience music utility and is not directed to children under 13, or the equivalent minimum age in the relevant jurisdiction. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us so that we can review and delete it as required by law.

11. Security

We use reasonable administrative and technical measures to protect information we receive. No method of electronic transmission or storage is completely secure, so we cannot guarantee absolute security.

12. Changes to This Policy

We may update this Privacy Policy to reflect changes to WristBeat, our practices, or applicable law. We will post the updated policy and revise the effective date. If a change materially affects how we handle information, we will provide appropriate notice and obtain consent where required before the new processing begins. App Store privacy disclosures will be reviewed when the App's data practices change.

WristBeat 隐私政策

生效日期：2026 年 9 月 3 日

WristBeat 是一款适用于 iPhone 和 Apple Watch 的节拍器应用，由独立个人开发者开发；开发者身份以 App Store 产品页上的提供者或销售者信息为准，以下称“我们”。本隐私政策适用于 WristBeat 应用、本网站及客服通信。开发者对本政策所述的个人信息处理负责，并在适用该概念的地区担任数据控制者。联系邮箱：support@wristbeat.watchosapp.com。

1. 概要

WristBeat 的核心节拍与练习功能可在设备上离线运行。iCloud 同步、打开网页、下载或更新 App、购买及发送邮件会涉及联网服务。设备和乐队同步还会使用相应的设备连接。

  • 无需注册账户；
  • App 内不包含广告、跟踪像素、第三方分析或崩溃报告 SDK；
  • 不出售个人信息，也不将其用于定向广告；
  • 节拍器设置、节奏、曲目、演出列表、练习历史及偏好保存在您的设备上。启用 iCloud 同步后，支持同步的 App 数据也会保存在您的个人 iCloud 账户中；我们不为这些内容另行运营账户或开发者云存储服务；
  • Apple Health 集成、麦克风功能及附近乐队同步均由您控制，相关数据处理方式见第 2 条；
  • 客服邮件、Apple 服务及网站访问可能涉及下文说明的有限信息，因此我们不会声称任何情况下都不会收到信息。

2. App 数据、同步和权限

WristBeat 可能在设备本地保存您创建或配置的信息，包括：

  • BPM、拍号、细分、重音、声音、视觉和触感设置；
  • 练习模式、计时器和音乐练习历史；
  • 曲目、曲目段落和演出列表；
  • 您主动创建的录音；以及
  • 主题和其他应用偏好。

这些信息通过 Apple 平台的存储机制保存，我们不会自动收到。它们会保留至您修改或删除相关内容、卸载应用或抹掉设备。如果您选择在客服消息中发送内容，该副本将作为客服信息处理。

iPhone 与 Apple Watch 同步

当您使用 iPhone 与 Apple Watch 同步时，所支持的设置、播放信息和内容通过 Apple 的设备通信服务在配对设备之间交换，不会把内容发送到开发者运营的服务器。附近乐队同步是另一项功能，见下文说明。

根据您的设备备份设置，Apple 可能保留 App 数据副本，包括 iCloud 备份。设备备份与 App 内云同步功能不同。从一台设备删除 App，不一定会删除另一台设备或备份中的副本。Apple 对备份及设备服务数据的处理适用 Apple 隐私政策。

iCloud

WristBeat 提供节拍器设置、曲目、演出列表、音乐练习历史和偏好的 iCloud 同步。启用后，这些内容保存在您的个人 iCloud 账户中，以便在您的其他设备上使用。存储与传输由 Apple 根据其隐私政策处理。我们不会收到您的 Apple 账户凭据，也不会通过开发者运营的服务器读取同步内容。

您可以在 App 设置中关闭同步，并通过设备的 iCloud 设置管理已存储的 App 数据。关闭同步本身不会删除已保存在 iCloud 中的数据；启用同步时，修改和删除可能同步至其他设备。音乐练习历史指 App 内的练习记录，不是健康或健身测量数据。WristBeat 不会将 HealthKit 数据或个人健康信息存入 iCloud，也不会通过 App 的 iCloud 同步上传麦克风音频或录音。设备备份仍受您单独设置的 Apple 备份选项管理。

Apple Health（HealthKit）

WristBeat 在 Apple Watch 上提供可选的“长时间练习”模式。当您主动启用时，App 会通过 HealthKit 启动系统运动会话，以支持较长时间的练习会话，包括放下手腕时的使用。运行仍受 Apple 系统权限、后台限制和电源管理影响；启动会话不意味着保证触感持续不中断。

启用此模式时：

  • WristBeat 不读取您的健康或健身数据，包括心率及已有的 Apple Health 记录；
  • WristBeat 不会将练习保存为运动记录，也不会向 Apple Health 写入健康或健身样本；
  • WristBeat 不会通过此模式上传、共享或以其他方式传输健康相关数据，也不会将其存储在 iCloud 中；
  • 会话仅在您启用该模式后开始，并在您停止播放、练习计时结束或系统终止会话时结束。

我们不会将健康数据用于广告、营销、用户画像或基于使用情况的数据挖掘，也不会向第三方披露健康数据。启动系统运动会话可能影响 watchOS 自身的活动追踪。根据设备设置和系统行为，即使 WristBeat 不保存运动记录，Apple 仍可能独立记录活动或在“健身”“健康”中计入锻炼时间。这些系统记录由 Apple 管理，您可以在 Apple 的 App 和设置中查看及管理。

您可以不启用“长时间练习”模式而使用核心节拍器，也可以关闭该模式，并在 Apple 的“健康”或设备设置中管理相关权限。使用 HealthKit 不代表 WristBeat 是医疗设备或治疗服务。

麦克风和录音

当您选择声音识别定速或练习录音功能时，WristBeat 会请求麦克风权限。音频在设备本地处理；声音识别使用音频估算速度，只有您选择录音时才会在设备本地保存录音。WristBeat 不会将麦克风音频或录音上传至开发者服务器、App 的 iCloud 同步或附近乐队同步设备。

您可以在 App 内停止识别或录音，也可以在设备设置中撤销麦克风权限。撤销后将停止进一步使用麦克风，但不会自动删除已保存的录音；您可以在 App 内删除录音。如果您另行主动分享录音，例如在客服邮件中发送，所选接收方会收到该副本。根据 Apple 备份设置，设备备份可能包含已保存的录音。普通节拍器无需麦克风权限即可使用。

蓝牙和附近乐队连接

乐队同步让您的设备直接连接附近运行 WristBeat 的设备，以便乐手共享节拍。交换的音乐信息包括速度、拍号、定时及同步消息；连接还会使用发现和连接参与设备所需的信息。乐队同步不传输音频、录音、健康数据或练习历史，也不经过开发者运营的服务器。

您决定何时发起或加入共享会话，可以退出或停止会话，并在设备设置中管理蓝牙或本地网络权限。参与设备会收到您共享的定时信息，请与可信任的参与者使用该功能。连接质量和系统行为可能影响同步效果。

3. 我们会收到的信息

客服通信

如果您联系我们，我们会收到您选择在消息中提供的信息，例如电子邮箱地址、消息内容和附件。

如果您使用 WristBeat 准备的客服邮件，其中可能包含国家或地区代码、首选语言、操作系统版本、App 版本，以及在可用时包含 Apple 供应商标识符（IDFV）。您可以查看邮件并决定是否发送，也可以在发送前移除其中的信息。WristBeat 不会自动发送准备好的客服消息。随邮件发送的标识符可能与您的邮箱地址关联，因此相关通信不一定是匿名的。请勿在客服消息中包含密码、支付卡信息或健康记录。

我们仅使用客服信息来回复您、排查问题、保护应用以及改进 WristBeat。

Apple 处理的信息

当您下载、购买、安装、更新或使用 WristBeat 时，Apple 可能依据其条款及隐私政策处理相关信息。根据您的设备及隐私设置，Apple 可能向我们提供 App Store 指标以及诊断或崩溃报告。App Store 指标可能经过汇总，而单份诊断报告可能包含设备、操作系统及崩溃技术信息；我们不会将所有报告一概描述为匿名或汇总信息。我们使用可获得的信息了解可靠性并修复问题，不用于跨 App 或网站跟踪您。您可在设备的“隐私与安全性”设置中管理 Apple 分析共享选项。

购买信息

WristBeat 可免费下载，并通过一次性内购提供付费功能，不属于自动续费订阅。App Store 付款由 Apple 处理。我们不会收到您的支付卡资料、Apple 账户密码或支付凭据。Apple 可能提供用于管理和购买支持的销售及交易信息。如果您向我们发送收据、订单编号或购买问题，我们会将其作为客服信息处理。设备上的购买核验和恢复购买通过 Apple 服务处理；WristBeat 不运营支付服务器。

网站访问和主题偏好

当您访问本网站时，托管及内容交付服务商可能处理 IP 地址、浏览器或设备信息、请求页面和访问时间等技术信息，以交付及保护网站。这与设备本地的节拍器使用不同。Cloudflare 提供本网站服务时的信息处理方式见 Cloudflare 隐私政策。

本网站使用浏览器本地存储保存您选择的浅色或深色主题。该偏好留在当前浏览器中，不用于识别您的身份，可通过清除本网站的浏览器数据删除。我们未在这些页面中加入广告 Cookie、跟踪像素或访客分析脚本。您打开 Apple 或其他外部网站的链接后，相关处理适用这些服务商自身的政策。

4. 信息用途

我们仅在必要情况下使用收到的信息，以便：

  • 提供客户支持并回复请求；
  • 诊断错误并提高可靠性；
  • 维护 WristBeat 的安全性和完整性；以及
  • 遵守适用法律并维护合法权利。

网站请求信息用于交付页面、防止滥用和维护服务安全。您为购买支持提供的信息用于回复请求及履行相关法律义务。

我们不会将个人信息用于广告、用户画像或数据经纪活动。

设备本地麦克风处理、iCloud 同步及附近节拍交换用于您选择使用的功能，具体见第 2 条。本政策中的一般客服及服务商披露不代表允许通过这些功能上传健康数据或麦克风录音。

5. 信息共享

我们不出售或出租个人信息，不为跨情境行为广告共享个人信息，也不向数据经纪商披露信息。我们仅可能在以下情况下披露信息：

  • 向代表我们提供客服通信、网站交付或安全服务的提供商披露，且其须遵守适当的保密和数据保护义务；
  • 根据您的指示或授权进行披露；
  • 为遵守法律、法律程序或有效的政府要求，或为保护用户、我们的权利或 WristBeat 的安全而合理必要时；或者
  • 在应用发生合并、收购、重组或转让时进行披露，但仍须遵守本隐私政策及适用法律。

6. 保存和删除

本地信息由您控制。您可以通过 App 内的操作删除曲目、演出列表、练习记录和录音，也可以从相应设备卸载 App 以删除本地 App 数据。卸载不一定会删除 iCloud、其他设备、Apple 设备备份中的数据或此前已分享给他人的副本。您可以通过 Apple 设置管理 iCloud 中的 App 数据；同步删除可能传播到已连接的设备。Apple 独立生成的“健康”和“健身”记录由您通过 Apple 的 App 和设置管理。浏览器主题偏好可通过清除本网站的浏览器数据删除。

客服通信及相关诊断信息通常仅保留至解决请求并保存合理的处理记录为止，一般不会超过客服请求关闭后的 12 个月；但法律要求更长保存期、为提出或抗辩法律主张所必需，或您另有要求的情况除外。

我们保留的诊断信息仅在排查可靠性问题或履行法律义务所合理必要的期间内保存。网站服务商可能根据其服务政策，为内容交付、安全及法律目的保存请求信息；该保存期限不由 App 的本地数据设置决定。

您可以发送邮件至 support@wristbeat.watchosapp.com，请求删除客服信息。为找到并核验相关通信，我们可能需要适当的信息。我们无法直接删除由 Apple 或其他服务商独立持有的信息，但会在法律要求的范围内提供协助，并在适当情况下指引您联系相关服务商。

7. 处理信息的法律依据

在法律要求说明处理依据的地区，具体依据取决于处理目的：

  • 应您的请求采取措施，或为提供 WristBeat 相关支持而履行约定；
  • 在相关地区认可此依据且不凌驾于您权利之上的前提下，为回复一般咨询、排查问题及保护 App 和网站而具有的合法利益；
  • 对依法需要同意的可选信息用途，取得您的同意；或者
  • 遵守法律义务。

您可以随时撤回同意，但撤回不影响此前已经依法完成的处理。

8. 跨境处理

客服通信及网站请求信息可能在您居住国家或地区以外处理，包括开发者或服务商运营所在地。法律要求时，我们会采用获得法律认可的跨境传输保障措施，您可以联系我们了解适用保障。留在您设备上的内容不会传给我们。您选择通过 iCloud 同步的数据由 Apple 根据其政策存储和传输；Apple 通过其他服务独立处理的信息也适用其政策。

9. 您的隐私权利

根据您所在地区的法律，您可能有权请求访问、更正、删除、限制处理或获取我们持有的个人信息副本，或者反对特定处理。您也可能有权向当地数据保护机构投诉。

如需提出请求，请联系 support@wristbeat.watchosapp.com。我们将在适用法律规定的期限内回复，并仅要求核验和处理请求所合理必要的信息。相关权利可能受到法定例外限制。由于 WristBeat 不设用户账户，而且我们无法访问本地 App 数据，因此无法代您检索或删除设备本地信息；这不影响您对我们持有的客服通信及其他信息享有的权利。

10. 儿童

WristBeat 是面向一般用户的音乐工具，并非专门面向 13 周岁以下儿童或相关地区规定的最低年龄以下儿童。我们不会故意收集儿童的个人信息。如果您认为儿童向我们发送了个人信息，请联系我们，我们将按法律要求进行审查和删除。

11. 安全

我们采取合理的管理和技术措施保护收到的信息。但任何电子传输或存储方式都不可能绝对安全，因此我们无法保证绝对安全。

12. 政策变更

我们可能为反映 WristBeat、信息处理方式或适用法律的变化而更新本隐私政策，并公布更新后的政策及生效日期。如果变更会对信息处理方式产生重大影响，我们会在新的处理开始前提供适当通知，并在法律要求时取得同意。App 数据处理方式变化时，也会复核 App Store 隐私披露。
