Privacy Policy for Captcha Reader

Effective Date: 12/8/2025

1. Introduction

"Captcha Reader" ("we", "us", or "our") is a browser extension designed to assist users in extracting text from images. We are committed to protecting your privacy. This Privacy Policy explains how we handle your data and assures you that your information remains private and secure.

2. Data Collection and Transmission

We do not collect, store, or transmit any personal data.

• No Server Transmission: All image processing is performed locally on your device using WebAssembly technology (Tesseract.js). No images, text, or user data are ever sent to external servers or cloud services.
• No Tracking: We do not track your browsing history, usage patterns, or personal information.
• No Analytics: We do not use third-party analytics software to monitor extension usage.

3. How We Handle Image Data

1. The extension temporarily accesses the specific image you selected.
2. The image data is processed in your browser's memory to extract numeric characters.
3. Once the text is extracted and copied to your clipboard, the image data is immediately discarded from memory.
4. No copies of the image or the extracted text are saved to your browser's storage or history by the extension.

4. Permissions Usage

We request the minimum permissions necessary for the extension to function:

• activeTab / scripting: Used to temporarily access the webpage you are currently viewing only when you trigger the extension. This allows us to read the image source you selected.
• contextMenus: Used to add the "Read Captcha" option to your browser's right-click menu.
• clipboardWrite: Used solely to copy the extracted numbers to your clipboard for your convenience. We do not have permission to read your clipboard history.

5. Third-Party Libraries

This extension utilizes Tesseract.js, an open-source OCR engine. The library files are bundled locally within the extension package. This ensures that no code is loaded from remote sources during operation, further protecting your privacy and security.

6. Children’s Privacy

Since we do not collect any personal data, our service is safe for users of all ages. We do not knowingly collect information from children under the age of 13.

7. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. Any changes will be posted on this page.
