ShiftTide – 隐私政策

最后更新 / Last updated: 2026-09-08

你的数据只存在你的设备上

ShiftTide 为隐私而设计。你的排班轮转、班型定义、锚定日期、提醒设置与偏好都以 JSON 形式保存在设备本地（含用于主屏幕小组件与 Live Activity 的 App Group 快照）。我们不运营任何服务器，不收集、不传输、也无法访问你的排班数据。App 不需要注册账号。

默认完全离线

查看月历、应用轮转预设、编辑自定义循环、调整班型、阅读统计，均在设备上完成。正常使用下，ShiftTide 不会把你的排班数据发给我们（我们也没有可接收的服务器）。

免费 iCloud 备份

ShiftTide 支持通过 Apple iCloud 同步你的本地排班文件。数据经 Apple iCloud 加密传输与存储，由你的 Apple 账户控制；我们不运营备份服务器，也无法读取你的 iCloud 内容。iCloud 备份对所有人免费，不是付费功能。

App Group（小组件与 Live Activity）

ShiftTide 使用 Apple App Group，让主 App、主屏幕小组件与 Live Activity 读取同一份本机排班快照。数据留在 Apple 沙盒内，不会上传至 Sparkfall Games。

可选的本机通知

你可选择开启班前提醒（默认关）。提醒由本机调度，非远程推送；我们不发营销通知，也不读取你的通知记录做分析。可在 ShiftTide 设置或 iOS 系统设置中随时关闭。

日历导出（仅在你主动操作时）

若你使用「导出到日历」或分享 ICS 文件（Pro），ShiftTide 会通过 EventKit 在你设备上创建或更新日历事件，或生成你可自行分享的文件。除非你主动点击导出，App 不会读写系统日历。导出内容由你自行选择发送渠道；我们不会收到被导出的内容。

系统 API

ShiftTide 使用 UserDefaults 与文件时间戳保存设置并同步小组件/Live Activity 快照（见 App 隐私清单中的 Required Reason API 声明）。这些数据仍留在设备上，不会因此上传到我们。

无广告、无追踪、无统计

ShiftTide 不含第三方广告、统计分析 SDK 或任何形式的追踪。这是永久产品政策。

内购说明

ShiftTide Pro 为一次性买断（非消耗型），由 Apple 通过 StoreKit 全程处理。我们不接收、不存储任何支付信息。购买状态由设备上的 StoreKit 校验；可随时在 App 内或 App Store 账户中恢复购买。

你的权利（GDPR / CCPA）

由于数据只存在于你的设备（及你主动启用的 iCloud）：访问与更正可在 App 内完成；删除可在 App 内清除排班或直接删除 App；Pro 用户可导出 ICS/日历分享作备份。我们无法访问你的排班数据，也不出售任何个人信息。隐私相关问询请联系下方邮箱。

儿童隐私

ShiftTide 不收集任何人（包括儿童）的个人信息。没有账号，也没有社交功能。

ShiftTide – Privacy Policy (English)

Your data stays on your device

ShiftTide is designed to be private. Your rotation schedules, shift type definitions, anchor dates, reminder settings, and preferences are stored locally on your device as JSON files (including the App Group snapshot used by the Home Screen widget and Live Activity). We do not operate any servers, and we never collect, transmit, or have access to your schedule data. ShiftTide does not require an account.

Fully offline by default

Browsing the month calendar, applying rotation presets, editing custom cycles, customizing shift types, and reading stats all happen on your device. In normal use ShiftTide never sends your schedule data to us (we do not run any servers that could receive it).

Free iCloud backup

ShiftTide can sync your local schedule files through Apple iCloud. Data is encrypted in transit and at rest by Apple under your Apple ID. We do not operate backup servers and cannot read your iCloud content. iCloud backup is free for everyone — not a paid feature.

App Group (widget and Live Activity)

ShiftTide uses an Apple App Group so the main app, Home Screen widget, and Live Activity can read the same on-device schedule snapshot. This data stays in Apple's sandbox on your device and is not uploaded to Sparkfall Games.

Optional local notifications

You may optionally enable shift reminders (off by default). Reminders are scheduled on your device only — not remote push. We do not send marketing notifications and do not read your notification history for analytics. Turn them off anytime in ShiftTide Settings or iOS Settings.

Calendar export (only when you choose)

If you use Export to Calendar or share an ICS file (Pro), ShiftTide uses EventKit on your device to create or update calendar events, or generates a file you can share yourself. ShiftTide does not read or write Calendar unless you tap export. We do not receive exported content.

System APIs

ShiftTide uses UserDefaults and file timestamps to save settings and sync the widget/Live Activity snapshot (declared under Required Reason APIs in the app's privacy manifest). That data remains on your device and is not uploaded to us.

No ads, no tracking, no analytics

ShiftTide contains no third-party advertising, no analytics SDKs, and no tracking of any kind. This is a permanent product policy.

In-app purchases

ShiftTide Pro is a one-time non-consumable purchase processed entirely by Apple through StoreKit. We do not receive or store any payment or billing information. Your Pro entitlement is verified on-device by StoreKit; you can restore purchases anytime from the app or your App Store account.

Your rights (GDPR / CCPA)

Because your data lives only on your device (and iCloud if you enable it):

• Access and correction — edit schedules and shift types directly in the app
• Deletion — clear schedules in Settings or delete the app to remove all local files
• Portability — export to Calendar / ICS (Pro) for your own backup

We cannot access your schedule data, and we do not sell personal information. For privacy inquiries, contact the email below.

Children's privacy

ShiftTide does not collect personal information from anyone, including children. There are no accounts and no social features.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date at the top.
