HistoryCloudSync EN

HistoryCloudSync helps you preserve, organize, and synchronize your browsing history beyond the limits of a standard browser history page. Instead of leaving your visits in a temporary, browser-bound log, it builds a dedicated local archive in IndexedDB and gives you a more portable, searchable way to revisit pages you have seen before. The extension is designed around three connected goals: storing browsing history locally, synchronizing that history with supported cloud providers, and letting you search your saved records directly from the address bar.

In day-to-day use, the extension runs in the background and captures browsing history through the browser history API. It records visited page URLs along with useful metadata such as page titles, last visit times, visit counts, and internal update timestamps. This local database acts as the extension’s primary history store, making it possible to maintain an independent searchable archive without relying only on the browser’s default interface. The package description also indicates that the extension updates this store as tabs finish loading, helping keep records current while skipping invalid internal browser pages and certain search-result URLs.

A central capability of HistoryCloudSync is cloud backup and synchronization. The extension can connect to Google Drive and OneDrive through OAuth authentication. According to the package, Google Drive synchronization uses the appDataFolder area, while OneDrive synchronization uses Microsoft Graph AppFolder storage. This means the extension works within each provider’s private application storage area rather than general user-visible folders. History records are serialized into JSON, compressed with gzip, and uploaded as snapshot files. During synchronization, remote snapshots are downloaded, merged with local records using update timestamps, written back into the local database, and then uploaded again as a fresh full snapshot. This process is intended to help multiple devices converge on the most up-to-date version of your saved browsing history.

Search is another important part of the experience. HistoryCloudSync registers an omnibox keyword so you can search locally stored history directly from the address bar. Suggestions are generated from recent local records to keep the experience responsive. Matching works against page titles and URLs, and the package also shows support for pinyin conversion of titles, allowing pinyin-based searching of Chinese text. When you select a suggestion, the result can open in the current tab or a new tab depending on how you confirm it.

The options page serves as a compact control center. From there, you can review the number of locally stored records, see the last sync time, connect or disconnect Google Drive and OneDrive, turn automatic synchronization on or off, enable or disable cross-device token synchronization, and trigger a manual sync whenever needed. Automatic synchronization can run on a schedule, when the browser becomes idle, and shortly after new history is captured through a delayed sync queue. Taken together, the package presents HistoryCloudSync as a practical solution for long-term history retention, cloud-backed continuity across devices, and quicker recall of previously visited pages.

Key Features:
- Stores browsing history in a dedicated local IndexedDB database with URLs, titles, visit counts, and timestamps.
- Synchronizes history snapshots with Google Drive and OneDrive using each provider’s private application storage area.
- Lets you search saved history directly from the address bar through an omnibox keyword.
- Matches search terms against page titles and URLs, with pinyin-based title search support for Chinese text.
- Merges local and remote history using update timestamps to keep the newest record version.
- Supports automatic sync through scheduling, idle-state triggers, and delayed sync after new history is saved.
- Provides manual controls for provider connection, sync status review, automatic sync settings, and immediate sync actions.

How It Works:
1. After installation or browser startup, the extension reads recent browser history and stores valid entries in its own local IndexedDB database.
2. As tabs finish loading, it updates the local history archive with new or changed visit information for supported pages.
3. If you connect Google Drive, OneDrive, or both, the extension authenticates with OAuth and stores the required token information for future syncing.
4. During sync, it downloads remote history snapshots from connected providers and compares them with local records.
5. The extension merges records using update timestamps, writes the newest information into the local database, and prepares an updated full snapshot.
6. The merged history data is compressed into gzip JSON and uploaded back to the connected cloud provider storage area.
7. When you use the extension’s omnibox keyword, it searches recent local history entries and suggests matches based on titles, URLs, and pinyin representations.

Privacy: - This extension collects browsing history data to provide local archiving, address bar search, and cloud synchronization. History records are stored locally in IndexedDB and may be uploaded to Google Drive appDataFolder or OneDrive AppFolder when those providers are connected. OAuth token information is also stored locally, and it may optionally be stored in browser sync storage if cross-device token synchronization is enabled.
