Privacy Policy

Learn how we collect, use, and protect your personal and financial data.

100% Client-Side Processing: Zero server uploads & zero retention

100% Client-Side Privacy: All browser tools operate locally inside your browser sandbox with zero server uploads.

At Grand Tool Box, accessible from our website, the privacy of our visitors is of paramount importance. This Privacy Policy document outlines the types of information collected and recorded by Grand Tool Box and how we utilize it.

If you have additional questions or require further clarification regarding our Privacy Policy, please contact us at grandtoolbox@gmail.com.

1. Document & Calculation Privacy

Grand Tool Box is designed to execute calculations, compress files, edit images, and process documents entirely client-side. When using our calculators or image/PDF tools:

  • No Server Uploads: Files, images, and text inputs are parsed directly inside your browser memory using JavaScript and WebAssembly. No data is transmitted to our servers.
  • Transient Storage: Processed files remain in active browser memory and are instantly cleared when you close or refresh the page tab.

2. Cookies and Local Storage

Like most modern web platforms, Grand Tool Box uses cookies and localStorage parameters to store user preferences and optimize browsing experience:

  • Theme Preference: Stores your light or dark UI theme selection.
  • Consent Preference: Stores your cookie notice choices.

3. Google Analytics & Web Performance

We use web analytics tools (such as Google Analytics) to analyze aggregate user engagement, traffic distribution, and page load performance. Analytics collection involves non-identifying technical metadata (browser type, device type, country region, viewport size) to help us optimize bandwidth and web app speed.

4. Google AdSense & Third-Party Advertising Disclosures

Grand Tool Box displays advertisements provided by Google AdSense and authorized third-party ad vendors:

  • Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to Grand Tool Box or other websites on the Internet.
  • Google's use of advertising cookies enables it and its partners to serve personalized ads to visitors based on browsing activity.
  • Users may opt out of personalized advertising at any time by visiting Google Ads Settings or via www.aboutads.info.

5. GDPR & CCPA Compliance

Under global data protection standards (GDPR, CCPA/CPRA), you have full rights over your data. Because our tools operate 100% locally on your machine, we do not build or hold database profiles of your files, documents, or personal identity.

6. User Consent

By accessing and using Grand Tool Box, you hereby consent to our Privacy Policy and agree to its terms.
