This is a lightweight, privacy-first single-page app (static HTML + JavaScript + CSS) for tracking smoking-related "punch" events (打卡). It runs entirely in the browser and stores all data locally using localStorage. No backend or account is required.

本项目是一个轻量级、注重隐私的单页应用（静态 HTML + JavaScript + CSS），用于记录与吸烟相关的“打卡”事件。所有数据仅保存在浏览器的 localStorage 中，无需后端或账号。

• Quick "punch" (打卡) to record the current time when a smoking event occurs.

• Daily summary: count, earliest/latest times, average interval between punches.

• Predicts how the average interval would change if you punch now.

• Recent history list (shows up to 5 most recent punches for today).

• Analysis section comparing today to yesterday and the same day last week.

• Encouragement area with a simple "quit progress" visual (progress bar).

• Reports modal with charts:

  • Daily hourly distribution chart (Chart.js)
  • Monthly & yearly placeholders (chart canvases included)

• Simple settings modal to customize:

  • App title
  • Today card title
  • Punch behavior name (e.g., "吸烟")

• All UI is responsive and designed for mobile devices.

• 快速「打卡」记录当前时间

• 每日报表：次数、最早/最晚时间、平均间隔

• 预测当前打卡后平均间隔会如何变化

• 最近打卡记录列表（显示今日最近最多 5 条）

• 数据分析：与昨日及上周同日对比

• 鼓励模块，包含简单的「戒烟进度」进度条

• 报告弹窗（含 Chart.js 图表）

• 设置弹窗：自定义应用标题、今日卡片标题、打卡行为名称

• 响应式设计，适配移动端

1. Open index.html in a browser (desktop or mobile) or host the folder on a static server.

   • You can simply double-click the file or run a static server (e.g., npx http-server).

2. Tap the main punch button to record a smoking event.

3. Click the "📊" reports button to open the reports modal and view charts by day/month/year.

4. Click the "⚙️" settings button to change titles or the punch name.

5. All data is stored locally. Clearing the browser storage will remove saved punches and settings.

6. 在浏览器中打开 index.html（桌面或移动端），或将目录放到静态服务器上托管。

   • 可以直接双击打开文件，或运行静态服务器（如 npx http-server）。

7. 点击页面上的打卡按钮记录一次事件。

8. 点击“📊”按钮打开报告弹窗，查看日/月/年图表。

9. 点击“⚙️”按钮进入设置，修改应用标题、今日标题或打卡名称。

10. 所有数据保存在本地，清除浏览器存储将删除打卡记录与设置。

• localStorage keys used:
  • punches — JSON array of punch objects
  • settings — JSON object containing the app settings

Punch object structure:

• id: timestamp-based unique id (Number)
• timestamp: epoch milliseconds (Number)
• date: YYYY-MM-DD string (local date)
• time: localized time string used for display (e.g., "14:30")

示例：

• localStorage 键：
  • punches — 打卡对象数组（JSON）
  • settings — 设置对象（JSON）

打卡对象结构：

• id：基于时间戳的唯一 ID（Number）
• timestamp：毫秒级时间戳（Number）
• date：本地日期字符串（YYYY-MM-DD）
• time：用于展示的本地时间字符串（例如 "14:30"）

Note: All data is local to the browser. There is no sync or cloud backup.

注意：所有数据仅保存在浏览器本地，不会同步或备份到云端。

• Chart.js (loaded via CDN)
  • <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>

Charts are created dynamically when the reports modal is opened or when the selected date changes.

图表通过 CDN 加载的 Chart.js 渲染（在 index.html 中引入）。

• index.html — The whole app (HTML, CSS, and JavaScript bundled in one file)

  • Contains UI components: header, punch card, history, daily report, settings modal, reports modal, notification component.
  • All app logic lives in inline <script> in index.html.

• icon-192.png, icon-512.png — App icons referenced in the head (if present)

• index.html — 含全部应用代码（HTML、CSS、JavaScript）

  • 包含主界面、打卡卡片、历史、日报表、设置弹窗、报告弹窗、通知组件
  • 应用逻辑直接写在 index.html 的内联 <script> 中

• icon-192.png, icon-512.png — 页面中引用的图标（若存在）

• App look & feel: edit CSS variables in the <style> :root at the top of index.html

  • --primary-color, --gradient, --background-color, border radius, etc.

• Change default settings (initial values) by editing the state.settings object in the script.

• Chart appearance: adjust Chart.js dataset options in generateDailyChart / generateMonthlyChart / generateYearlyChart.

• 样式与配色：编辑 index.html 顶部 :root 中的 CSS 变量

  • 如 --primary-color、--gradient、--background-color、圆角等

• 默认设置：在脚本中修改 state.settings 的初始值

• 图表样式：修改 generateDailyChart / generateMonthlyChart / generateYearlyChart 中的数据集选项

Key JavaScript functions and state:

• state — holds:
  • punches: array
  • settings: { appTitle, todayCardTitle, punchName }
  • charts: { daily, monthly, yearly } (Chart.js instances)
• initApp() — initializes elements, loads data, attaches listeners.
• loadData() / saveData() — read/write localStorage.
• handlePunch() — create a punch entry for current time and save.
• renderUI() — update counts, average interval, history list, daily report, analysis, encouragement.
• generateDailyChart(date) — builds hourly bar chart for a given date.
• generateMonthlyChart(), generateYearlyChart() — placeholders included (can be implemented to aggregate by month/year).
• generateAnalysisReport() — compares today with yesterday and last week and gives a simple trend message.
• generateEncouragement() — shows friendly messages and a crude progress-based progress bar.

重要函数与状态说明：

• state：
  • punches：打卡数组
  • settings：{ appTitle, todayCardTitle, punchName }
  • charts：{ daily, monthly, yearly }（Chart.js 实例）
• initApp()：初始化元素、加载数据并绑定事件
• loadData() / saveData()：读写 localStorage
• handlePunch()：记录当前时间的打卡并保存
• renderUI()：更新界面数据、每日报表、分析与鼓励模块
• generateDailyChart(date)：为指定日期生成按小时统计的柱状图
• generateMonthlyChart(), generateYearlyChart()：月/年图表占位，可实现月/年聚合
• generateAnalysisReport()：与昨日/上周对比并给出趋势分析
• generateEncouragement()：展示鼓励信息和简单进度条

• Data is stored only in localStorage — if the user clears browser data, punches will be lost.

• No import/export functionality for backup.

• Monthly/yearly charts are scaffolded but may need additional aggregation logic depending on desired behavior.

• Timezone/localization uses the browser locale; tests needed for cross-timezone usage if you open the page in different locales.

• 数据仅保存在 localStorage，清除浏览器数据将丢失记录

• 暂无导入/导出功能来备份数据

• 月/年图表需要根据实际需求扩展聚合逻辑

• 时间使用浏览器本地设置，跨时区使用需额外测试

• Add an export/import CSV or JSON feature for backup and analysis.
• Provide an option to choose between 24-hour / 12-hour format.
• Add a confirmation for accidental multi-taps (debounce punch button).
• Implement monthly/yearly aggregation and summary charts.
• Add optional passcode or browser-based encryption for increased privacy.
• 增加导出/导入 CSV 或 JSON 的功能用于备份与分析
• 提供 24 小时 / 12 小时格式切换
• 防止重复快速点击（防抖/节流）
• 完善月/年聚合统计并增加图表展示
• 可选的本地加密/密码保护以增强隐私

You can add a license file as needed (e.g., MIT). The project currently has no license file included.

可根据需要添加许可证（例如 MIT）。当前仓库中未包含许可证文件。

If you'd like, I can:

• generate a README file in the repository,
• add export/import functionality,
• implement monthly/yearly aggregation and examples,
• or translate in a different tone (shorter/longer).

如果你需要，我可以：

• 直接在仓库中生成 README 文件，
• 添加导出/导入功能，
• 完成月/年聚合并实现相应图表，
• 或者用不同风格（更短或更详细）重写 README。
