静阶 HushStep 是媒体音量与屏幕亮度调节工具。我们不要求注册账户，不接入广告或第三方行为分析 SDK，不将您的预设或设备音量上传到开发者服务器。
1. 在设备上使用的信息
App 读取当前媒体音量、可用音频输出路由和屏幕亮度，用于显示状态及执行您发起的调节。静阶不录制麦克风、不读取您播放的音频内容，也不需要照片、通讯录或位置权限。
您保存的预设名称、图标、音量和可选亮度，以及步长、语言偏好和购买权益缓存，存放在设备本地。App 与其小组件通过本应用的 App Group 共享必要数据，包括所选预设和待执行的快捷操作；该共享容器不是开发者云服务。
2. 小组件与快捷操作
您从小组件、主屏快捷项或快捷指令发起操作时，系统可能启动 App 或要求解锁设备。App 使用本地预设信息完成请求。您创建的预设名称可能显示在已添加的小组件、主屏快捷菜单和 Siri / 快捷指令中。静阶不依靠后台常驻服务持续修改音量或亮度。
3. 购买与恢复
Pro 购买、付款、退款及 Apple 账户验证由 Apple 的 App Store 和 StoreKit 处理。App 使用 StoreKit 提供并校验的交易结果识别购买权益，在本地保留用于界面显示的权益状态。开发者不会因此取得您的银行卡资料或 Apple 账户密码。
App 启动时加载产品信息、刷新权益，以及购买和恢复购买，都可能与 Apple 服务通信。Apple 如何处理账户和交易信息，适用其隐私政策与服务条款。静阶没有独立的购买验证服务器，也不建立自有购买账户。
4. 数据的保留与删除
您可在 App 内编辑或删除预设；应用会保留至少一个预设。您可通过系统移除小组件或卸载 App。App 数据是否随设备备份、迁移或恢复，由 iOS 设置与系统行为决定。卸载 App 不等于撤销已完成的 App Store 购买，恢复权益仍由 Apple 账户的购买记录决定。
5. 联系支持
如果您主动发送邮件，我们会收到您提供的邮箱地址、问题描述和附件，用于回复、排查及处理支持请求。请只提供必要信息，发送截图前遮盖私人内容，不要发送 Apple 账户密码或完整支付资料。
6. 本网站
本网站提供静态产品、政策和帮助页面，不使用 Cookie、广告、分析追踪脚本或第三方字体。为交付网页，网站服务器会接收 IP 地址、请求路径等必要网络信息，并可能因安全与故障排查需要处理访问记录。网站访问与 App 内本地预设是不同的数据处理场景。
点击 App Store、备案网站或发送邮件后，相应服务按其自身规则处理信息。
7. 政策更新与联系
如果产品的数据处理方式变化，我们会更新本页面及日期。对本政策或相关数据处理有疑问，请联系深圳随岸科技有限公司：support@diduai.top。

1. Information used on your device
HushStep reads current media volume, available audio output routes and screen brightness to display status and apply your adjustments. It does not record your microphone or read the audio content you play. It does not require access to your photos, contacts or location.
Preset names, icons, volume and optional brightness, step size, language preferences and an entitlement cache are stored locally. The app and its widget share necessary settings, selected presets and pending shortcut requests through the app's local App Group container. This is not a developer-operated cloud service. HushStep requires no account and includes no advertising or third-party behavioral analytics SDKs. Presets and device volume are not uploaded to our servers.
2. Widgets and shortcuts
A widget, Home Screen quick action or shortcut may open HushStep or require you to unlock your device. The app uses local preset data to carry out your request. Preset names may appear in widgets you add, Home Screen quick actions and Siri / Shortcuts. It does not run a persistent background service to continuously change volume or brightness.
3. Purchases and restoration
Apple's App Store and StoreKit handle payments, refunds and Apple Account verification. HushStep uses verified StoreKit transaction results to determine your entitlement and caches the status locally. We do not receive your payment-card details or Apple Account password. Loading product information and refreshing entitlements at launch, purchasing and restoring purchases may communicate with Apple services. Apple's privacy policy and terms apply to that processing. HushStep has no separate purchase-validation server or developer purchase account.
4. Retention and deletion
You can edit or delete presets in the app, which keeps at least one preset. You may remove widgets or uninstall the app using iOS. Device backup, migration and restoration are controlled by your system settings and iOS. Uninstalling the app does not cancel an App Store purchase; restored entitlement depends on your Apple Account purchase record.
5. Support
If you email us, we receive the email address, description and attachments you choose to provide. We use them to respond to and resolve support requests. Please share only necessary details and remove private information from screenshots. Do not send account passwords or full payment details.
6. This website
This static website uses no cookies, advertising, analytics scripts or third-party fonts. Hosting servers receive necessary network information, including an IP address and requested path, to deliver pages and may process access records for security and troubleshooting. Website traffic is separate from your app's local presets. External websites and email providers apply their own privacy rules.
7. Changes and contact
We will update this page and its effective date if our practices change. Contact Shenzhen Sui'an Technology Co., Ltd at support@diduai.top.
