1. How We Collect and Use Information

This site does **not** actively collect any Personally Identifiable Information (PII). We only collect the following non-personal information for the purpose of maintaining, optimizing website performance, and analyzing traffic:

  • Locally Processed Data: We do not store any text, code, or file content you input into the tools. They are processed only on your local device.
  • Basic Browser Information: Includes your IP address, browser type, device type, access time, and referring website. This information is used to analyze website traffic and diagnose technical issues.

2. Third-Party Services and Cookie Policy

We rely on third-party services to support website operations, ad serving, and traffic analysis. These services use Cookies or similar technologies to collect anonymous data to improve their services and ad performance:

  • Google AdSense: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.
    You can visit Google Ad Privacy & Terms and opt out of personalized advertising at any time via Google Ad Settings, or by visiting www.aboutads.info.

For local OCR engines like Tesseract.js, data runs entirely on your physical device.
