Privacy Policy

1. Overview

QGJ Tools (“this website,” “we”) is a free collection of online tools. We take your privacy seriously. This policy explains what information we collect when you use this website, how we use it, and what rights you have. By using this website, you agree to the practices described in this Privacy Policy.

2. Your data is processed locally

The core processing for the vast majority of tools on this site (such as image processing, file format conversion and calculators) runs entirely in your browser — the files or text you upload or enter are never sent to our servers. This is one of our core design principles. A small number of lookup-style tools (for example, features that need to query public information) may need to send the necessary query content to a third-party service provider; this is noted separately on the relevant tool's page.

3. Information we collect

Aside from the content you actively enter while using a specific tool, we automatically collect some technical information through the following means:

• Usage analytics (Google Analytics): we use Google Analytics to understand how the site is used — for example page views, popular tools, and device-type statistics — to help us improve the site. Google may set cookies on your device as part of this process. You can disable cookies in your browser settings, or install theGoogle Analytics Opt-out Browser Add-onto opt out.
• Advertising (Google AdSense): this site may display advertisements served by Google AdSense. Google and its partners may use cookies (including the DoubleClick cookie) to show you personalized ads based on your past visits to this and other websites. You can visit theGoogle Ads Settings pageto opt out of personalized advertising. Third-party vendors, including Google, may also use cookies to serve ads to you on other sites across the internet based on your prior visits to this website.
• Basic access logs: like most websites, our servers may automatically log some basic technical information such as access time, approximate location, browser type, and the page URL visited, mainly for security maintenance and troubleshooting.

4. Use of cookies

This website and third-party services (Google Analytics, Google AdSense) may use cookies or similar technologies. You can manage or delete cookies at any time through your browser settings, though doing so may affect some of the site's functionality.

5. How we use information

The technical information we collect is used only for the following purposes: improving site functionality and user experience, analyzing tool usage, maintaining site security, and serving and optimizing advertising. We do not sell your personal information to third parties.

6. Third-party links and services

This website may contain links to third-party websites or embed third-party services (such as fonts or ads). These third parties have their own independent privacy policies, and we are not responsible for their content or privacy practices. We recommend reviewing their privacy policies separately before use.

7. Children's privacy

This website is not directed at children under the age of 13, and we do not knowingly collect personal information from them. If you believe we have inadvertently collected a child's personal information, please contact us using the information below and we will address it promptly.

8. Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page, along with an updated “Last updated” date at the top. We recommend checking this page periodically to stay informed.
