应用将你选择的照片、文字和二维码在本机转换为图片，经 NFC 发送到兼容的墨水屏手机壳。手机壳上的画面可能被他人看到或扫描。应用没有内容上传服务器、广告或分析 SDK，不自动上传照片、日程或二维码。
日程功能需要系统日历完整访问权限，只读取你选择的日历，不修改事件或上传日程。待办功能需要提醒事项完整访问权限，只读取你选择的清单中今天到期及已逾期的未完成事项，不修改或上传待办；可独立关闭，拒绝待办权限不影响日程投屏。所见内容取决于系统日历此刻已同步的信息，应用不强制刷新云端日历。图片来自系统选择器或你主动分享的图片，不扫描整个照片库。二维码在本机识别。每日提醒使用本地通知，你可以在应用内关闭提醒或在系统设置撤回权限。
天气默认关闭，由你在设置中搜索并选择城市。应用不申请手机定位权限。城市查询向 Apple 发送你输入的城市名称；天气查询向 Apple WeatherKit 发送所选城市的坐标。日程标题、地点、待办正文、照片和二维码不会发送给天气服务。天气需要联网，查询失败时不影响日程与待办投屏。温度为所选城市的摄氏温度，降水概率为下一项日程时段在所选城市的预报，不推断目的地或计算路线。
应用保存你选择的日历、待办清单与显示开关、提醒时间、天气城市与开关和图片处理设置，并单独保存你指定的背景图片，用于恢复显示。临时投屏内容不会覆盖保存的背景。运行记录在本机保存操作类型、阶段、时间、耗时、NFC 状态与错误信息；不记录照片、日程正文、待办正文、二维码正文、手机壳序列号、NFC UID 或认证令牌；保留非唯一的硬件配置用于兼容性排查。日志是有限历史，不保证保留每次操作。
你可以在设置中更换背景，并在 iOS 设置中撤回日历、提醒事项或通知权限。删除应用（不是仅卸载并保留数据）会删除本机应用容器中的文件和设置。删除应用不会清除手机壳已显示的画面，也不会删除你导出的文件；可通过再次投屏更换画面，并在导出位置单独删除文件。

Local processing
Selected photos, text and QR codes are converted to images on your iPhone and sent to a compatible e-paper case through NFC. Other people may see or scan the case display. There is no content-upload server, advertising or analytics SDK; photos, calendar events and QR content are not automatically uploaded.
Permissions
Calendar cards require full calendar access and only read your selected calendars, never modify events or upload them. To-dos require full Reminders access and only read incomplete tasks due today or overdue from your selected lists. Tasks are never modified or uploaded. You can disable this feature; denying Reminders access does not block calendar casting. Content reflects what the system calendar has synced; the app does not force cloud synchronization. Images come from the system picker or your explicit shares; the app does not scan your entire photo library. QR recognition is local. Daily reminders use local notifications, which can be disabled in the app or iOS Settings.
Optional weather
Weather is off by default. Choose a city in Settings; the app does not request phone location. City search sends the city name to Apple, and WeatherKit receives the chosen city coordinates. Event titles, event locations, task text, photos and QR payloads are not sent to the weather service. A network connection is required. Failed weather queries do not block agenda casting. Temperatures use Celsius; precipitation probability refers to the selected city at the next event’s time, without inferring destinations or calculating routes.
Local storage and diagnostics
The app stores selected calendars, to-do lists and the inclusion preference, reminder times, the chosen weather city and toggle, image settings and a separately selected background for restoration. Temporary casts do not replace that background. Bounded local diagnostics retain operation types, stages, times, durations, NFC status, error codes and non-unique hardware configuration. They exclude photos, event and to-do text, QR payloads, case serial numbers, NFC identifiers and authentication tokens. The history does not guarantee retention of every operation.
Optional support
Files leave the app only when you explicitly export or share them using a channel you choose. If you send support email, the developer processes your email address, message and diagnostic attachment only to troubleshoot, never for advertising or sale. Diagnostic attachments are deleted within 30 days after the issue is closed; you may request deletion at any time. Your email service handles transmission and storage.
Deletion and withdrawal
You can replace the background in the app and revoke calendar, Reminders or notification permission in iOS Settings. Deleting the app (rather than offloading it while retaining data) removes its local files and settings. Deletion does not erase the case display or exported files; cast a replacement image and delete exports separately.
