Tasks: Task names, icons, colors, estimated sessions, and archive states created by you.

Focus records: Completed minutes, session counts, dates, associated tasks, and notes.

Timer and reminder preferences: Focus and break durations, long break intervals, daily goals, automatic start options, ambient sound selection and volume, the completion chime switch, alarm-volume / notification-volume / vibration-only alert mode, the automatic Do Not Disturb switch, language, and theme. Alerts remain subject to system volume, Do Not Disturb rules, notification permission, and device restrictions.

Automatic Do Not Disturb takeover record: Private SharedPreferences (focus_dnd.xml) store the system interruption mode the app attempts to apply, for later restoration and to avoid overriding your choices. This is not notification history and contains no notification content, contacts, or messages. This temporary record is excluded from the app-configured Android system backup and device transfer, and from JSON / CSV exports.

This information is initially saved in local app-private storage (Room database and SharedPreferences); backup and export copies are described below. The app does not request the INTERNET permission and does not upload this information to our servers.

Your focus data stays on your device until you delete items, clear data, or uninstall the app.

The app supports automatic local backups to Download/Pomodoro. Backups are stored locally on your device and are never accessible to developers.

You can export and import JSON backups, or export CSV spreadsheets. These files are not additionally encrypted; keep them secure. A cloud file provider selected in the system picker may sync exported files under its own policy. Storage permission denial or write failures can prevent automatic backup.

Android may back up eligible databases and settings to your own account or transfer them to a new device according to system backup and migration settings. This is a system service; developers cannot access your system backup.

Notifications (POST_NOTIFICATIONS): Used to show active timer controls and notify you when a session finishes.

Exact Alarms (USE_EXACT_ALARM / SCHEDULE_EXACT_ALARM): Used for countdown completion alerts. If exact alarms are unavailable, the app attempts a system-permitted window-alarm fallback; alerts may be delayed and are not guaranteed to be punctual.

Do Not Disturb access (ACCESS_NOTIFICATION_POLICY): Only after you explicitly grant access in system settings and enable automatic Do Not Disturb in the app will it attempt to switch from allowing all interruptions to priority interruptions during a running countdown focus session. It does not take over during breaks, pauses, or stopwatch mode, or when Do Not Disturb was already enabled. This access queries and adjusts the system interruption mode; it does not read any notification content.

When focus ends, is paused, or the feature is disabled, the app attempts to release the Do Not Disturb mode it applied. It compares the current mode with its takeover record before restoring; if it detects that you changed to another mode, it does not overwrite that mode. It cannot identify every repeated selection of the same mode. Revoked access, system rejection, or process interruption may delay restoration; unresolved records are retained for a later synchronization or app reopening to retry. Immediate or universal restoration is not guaranteed. You can always adjust Do Not Disturb yourself in system settings.

Boot Completed (RECEIVE_BOOT_COMPLETED): Used to resynchronize timer state and reminders after your device restarts.

Storage (WRITE_EXTERNAL_STORAGE, Android 9 and below only): Used solely to save local backup files to public Downloads on older Android versions.

The app contains no third-party ads, tracking, or crash analytics SDKs.

We never sell, share, or disclose any of your data to third parties.

任务信息：您创建的专注任务名称、图标、颜色、预计番茄数和归档状态。

专注记录：您完成的专注时长、番茄数、所属任务、日期和备注。

计时与提醒偏好：专注与休息时长、长休息间隔、每日目标、自动开始选项、背景白噪音选择与音量、到点提示音开关、闹钟音量／通知音量／仅振动提醒方式、自动勿扰开关、语言和主题设置。提醒效果仍受系统音量、勿扰规则、通知权限与设备限制影响。

自动勿扰接管记录：应用在私有 SharedPreferences（focus_dnd.xml）中记录自己尝试设置的系统勿扰模式，用于后续恢复与避免覆盖用户选择。它不是通知历史，不包含通知内容、联系人或消息。该临时记录不纳入应用配置的 Android 系统备份或设备迁移，也不包含在应用导出的 JSON／CSV 中。

这些信息首先保存在本应用的本地私有存储（Room 数据库与 SharedPreferences）中；备份与导出副本见下节。本应用未声明网络权限（android.permission.INTERNET），不向我们的服务器上传这些信息。

您的数据将一直保存在您的设备中，直到您主动删除、清除应用数据或卸载应用。

应用支持自动将数据备份至设备的 Download/Pomodoro 目录。自动备份文件仅保存在本地设备，开发者无法访问。

您可以手动导出/导入 JSON 备份，或导出 CSV 表格。文件没有额外加密，请妥善保管。若在系统文件选择器中选择云盘，该服务可能按其政策同步文件。存储权限被拒绝或写入失败时，自动备份可能无法完成。

Android 系统可能按您的备份或设备迁移设置，备份符合应用规则的数据库和设置到您自己的账号或新设备；这是系统功能，开发者无法访问。

通知权限（POST_NOTIFICATIONS）：用于在计时进行中展示常驻控制通知，并在专注或休息结束时提醒您。

精确闹钟（USE_EXACT_ALARM／SCHEDULE_EXACT_ALARM）：用于倒计时到点提示。精确闹钟不可用时，应用尝试使用系统允许的窗口闹钟兜底，提示可能延迟，并非准时保证。

勿扰访问权限（ACCESS_NOTIFICATION_POLICY）：只有您主动在系统设置中授权并开启应用内自动勿扰，应用才会在正在运行的倒计时专注阶段尝试将系统从允许所有打扰切换为优先打扰；休息、暂停和秒表模式不主动接管。您原本已开启的勿扰模式不会被接管。此权限用于查询和调整系统勿扰模式，不用于读取任何通知内容。

专注结束、暂停或关闭该功能时，应用尝试解除自己设置的勿扰。恢复前会比较当前系统模式与接管记录；若检测到您已改为其他模式，不会覆盖该模式。应用无法识别所有同模式的再次选择。权限被撤销、系统拒绝或进程中断可能使恢复延迟；未完成的恢复记录会保留，供后续同步或重新打开应用时重试，不能保证立即或始终恢复。您可随时在系统设置中自行调整勿扰。

开机广播（RECEIVE_BOOT_COMPLETED）：用于在手机重启后重新同步计时状态与提醒。

存储权限（WRITE_EXTERNAL_STORAGE，仅 Android 9 及以下）：仅用于在低版本系统上将备份保存至公共下载目录。Android 10 及以上使用 MediaStore，无需此权限。

本应用不集成任何第三方广告、行为统计或崩溃分析 SDK。

本应用不会出售、共享或向任何第三方披露您的任何数据。
