• 💾 数据完全自持：账本数据保存在你的 GitHub 私人仓库中，无需任何第三方服务器。
• 👥 多人协作：通过 GitHub Collaborator 功能即可共享账本，实时同步修改。
• ⚡️ 增量同步：只上传/下载变更数据，大幅缩短同步时间。
• 📊 丰富的统计分析：支持多维度筛选与走势分析，可自定义分析视图。
• 🏷️ 分类与标签系统：支持二级分类、自定义标签、图标、排序。
• 💰 预算管理：按分类或标签设置预算并实时监控进度。
• 🖼️ 附件支持：可为账单上传图片附件。
• 📱 PWA 支持：可安装到桌面，像原生 App 一样使用，支持 iOS 与 Android。
• 🔒 完全开源：部署成本几乎为零，代码完全可审计、可自建。

Cent 是一个“纯前端”的 PWA 应用。
除 GitHub OAuth 登录外，Cent 不依赖任何后端服务。

了解详情：现在开始将Github作为数据库

• 每个账本（Book）即为一个 GitHub 仓库。
• 数据以 JSON 格式存储在仓库中，支持历史版本回滚。
• 通过仓库名识别账本，实现多账本管理。

Cent 内置一套自定义的增量同步策略，仅同步增量差异：

• 首次同步：完整下载数据。
• 后续同步：仅传输新增或修改部分。
• 支持离线缓存与断点续传。

该机制显著提升了同步效率，使得多人协作体验流畅自然。

同步逻辑经过抽象封装，未来将支持：

• 自建服务器
• 网盘（如 Dropbox、OneDrive）
• 本地离线账本

You might only need an accounting software.

Cent is a completely free, open-source, collaborative accounting Web App,
which uses a GitHub Repository for data synchronization and version control, enabling real-time cross-platform sync without a server.

🔗 Live Demo: https://cent.linkai.work
💾 Open Source Repository: https://github.com/glink25/Cent
📖 Blog: https://glink25.github.io/tag/Cent/

• 💾 Fully Self-Contained Data: Ledger data is stored in your private GitHub repository, without any third-party servers.
• 👥 Multi-User Collaboration: Share ledgers and synchronize changes in real-time using the GitHub Collaborator feature.
• ⚡️ Incremental Sync: Only uploads/downloads changed data, significantly reducing sync time.
• 📊 Rich Statistical Analysis: Supports multi-dimensional filtering and trend analysis, with customizable analysis views.
• 🏷️ Category and Tag System: Supports two-level categories, custom tags, icons, and sorting.
• 💰 Budget Management: Set budgets by category or tag and monitor progress in real-time.
• 🖼️ Attachment Support: Allows uploading image attachments for bills.
• 📱 PWA Support: Can be installed to the desktop and used like a native App, supported on iOS and Android.
• 🔒 Completely Open Source: Deployment cost is nearly zero, the code is fully auditable and can be self-hosted.

Cent is a "pure frontend" PWA application.
Apart from GitHub OAuth login, Cent does not rely on any backend services.

• Each ledger (Book) corresponds to a GitHub repository.
• Data is stored in JSON format within the repository, supporting historical version rollback.
• Multi-ledger management is achieved by identifying ledgers via repository names.

Cent incorporates a custom incremental synchronization strategy, only syncing the differential changes:

• Initial Sync: Full data download.
• Subsequent Sync: Only transfers newly added or modified parts.
• Supports offline caching and resume capability.

This mechanism significantly improves sync efficiency, leading to a smooth and natural collaborative experience.

The synchronization logic has been abstracted and encapsulated, with future support planned for:

• Self-hosted Servers
• Cloud Drives (e.g., Dropbox, OneDrive)
• Local Offline Ledgers
