Privacy Policy – Manga Tracker Pro

Last updated: June 2026

Overview

Manga Tracker Pro is a browser extension that helps you track your manga reading progress. We are committed to protecting your privacy. This policy explains what data the extension handles and how.

Data We Collect

Manga Tracker Pro does not collect, transmit, or share any personal data.

The extension stores the following information locally on your device only, using the browser's built-in chrome.storage.local API:

• Manga titles you have saved
• Chapter numbers you have visited
• URLs of manga pages you have tracked
• Timestamps of your reading sessions

This data never leaves your device. It is not sent to any server, analytics service, or third party.

Permissions Explained

• storage – Required to save your manga list and reading history locally on your device.
• contextMenus – Used to add a "Save manga to Tracker" option when you right-click on a manga page.
• Access to all websites (<all_urls>) – The extension needs to run on every page so it can automatically detect when you are reading a manga chapter on any supported site (60+ sites are supported). The extension only activates and saves data when a manga chapter URL or page content is detected; it does not read, modify, or interact with any other website content.

Data Sharing

We do not share any data with third parties. There are no analytics, no tracking pixels, and no external network requests made by this extension.

Data Deletion

You can delete all stored data at any time by:

• Using the "Clear all" option inside the extension popup, or
• Removing the extension from Chrome, which automatically deletes all local storage.

Changes to This Policy

If we make changes to this privacy policy, we will update the "Last updated" date above. Continued use of the extension after changes constitutes acceptance of the updated policy.
