Privacy Policy for A-Plus Publisher

Last Updated: May 20, 2026

1. Introduction

A-Plus Publisher: Comparison Chart Pro ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use our Chrome Extension.

2. Data Collection and Usage

The A-Plus Publisher extension is designed with a privacy-first approach. We do not collect, transmit, or store your personal data on any external servers.

Local Data Processing

All data processing, including reading Excel files and generating comparison charts for Amazon, happens locally on your computer within your browser. The extension uses Chrome's local storage capabilities to maintain a queue and history of your processed charts, ensuring that your data never leaves your device.

3. Permissions Explained

To function correctly, the extension requires the following permissions:

• storage & unlimitedStorage: Used strictly to save your current charting queues and historical data locally on your device.
• sidePanel: Allows the extension to display its user interface alongside your web browsing experience.
• scripting: Necessary to inject the automation scripts into Amazon Seller/Vendor Central pages to automatically fill out comparison charts on your behalf.
• Host Permissions: Access to Amazon domains (e.g., amazon.com, amazon.co.uk) is required to automate the data entry on those specific sites.

4. Third-Party Services

We do not use any third-party tracking, analytics, or external APIs that collect your data. Your Amazon credentials and session data are handled natively by your browser and are never accessed or transmitted by our extension.

5. Changes to This Policy

We may update our Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last Updated" date. We encourage you to review this Privacy Policy periodically for any changes.
