Manga Watchlist Companion (Chrome extension) · Last updated April 29, 2026

What the extension does

The extension helps you sync manga and manhwa reading progress to your Manga Watchlist account. By default it talks to the official Manga Watchlist server at https://app.mangawatchlist.space. Advanced users can point the extension at a different deployment from the options page. The extension does not host manga content or replace a publisher's website.

Data the extension collects

The extension does not sell, rent, or trade personal data. It contains no third-party analytics or advertising SDKs.

Stored on your device only

  • Settings you enter — backend URL, auto-track toggle, prompt cooldown — kept in chrome.storage.local on your machine.
  • A small rolling debug log of the last 25 sync events, also local-only, to help you troubleshoot.

Sent off your device

  • Your Manga Watchlist server only. When you save progress or refresh the unread badge, requests go to the configured backend URL (default: the official server above). These requests include chapter URLs, series titles, and numeric chapter identifiers needed to update your bookmarks.
  • MangaDex (optional, read-only metadata). On mangadex.org chapter pages, the extension may call the public api.mangadex.org endpoint to read chapter and series metadata. No MangaDex account is required; no Manga Watchlist credentials are sent to MangaDex.

The extension never sends your reading activity to the extension author or to any other third party.

Permissions (why each one exists)

  • storage — save your backend URL and preferences locally.
  • activeTab — read the current tab when you use the popup, shortcut, or context menu to track a chapter.
  • tabs — find the active tab to message the content script and open your dashboard.
  • alarms — wake the background worker periodically (~30 min) to refresh the unread chapter badge.
  • contextMenus — provide the “Track this manga chapter” right-click action.
  • Host access (content script <all_urls>) — manga and manhwa are read on hundreds of independent domains and mirrors. The content script only inspects the page you are on for chapter cues; the extension itself only requests host permission for the configured Manga Watchlist server (and, on MangaDex pages, the public MangaDex API via CORS).

Sign-in and session

You sign in in the browser on the Manga Watchlist website. The extension reuses that session cookie when calling the API, the same way the dashboard would. The extension author cannot access your password or session.

Your choices

  • You can uninstall the extension at any time; Chrome removes its local storage automatically.
  • You can clear local data from the extension's Settings page without uninstalling.
  • You can override the backend URL in Settings to point at your own deployment, or revert to the default.

Open source

The extension source code is available on GitHub at github.com/somaqzz12/manhwa-manga-tracking-Through-out-different-websites. If you have questions or requests, use the project's Issues page on GitHub.
