Zero-Knowledge & Client-Side Architecture

Privacy Policy

Last Updated: August 2026. At QuickToolkit (quicktoolkit.net), we believe privacy is a fundamental human right. Our tools are engineered from the ground up so your sensitive data never leaves your device.

Core Privacy Principles

No File Uploads

Images, PDFs, and document files are processed directly in your browser using HTML5 Canvas and WebAssembly. No files are ever sent across the wire to any server.

No Account Required

You do not need to register, create a profile, or give us your email address or personal credentials to use our suite of utility tools.

Local Browser Storage

User preferences (such as dark mode selection and cached currency exchange rates) are kept strictly in your local browser storage (`localStorage`).

1. Information We Do NOT Collect

Unlike traditional online converters that upload your PDFs and photos to cloud servers for remote conversion and temporary caching, QuickToolkit operates 100% client-side. We never view, transmit, harvest, or retain:

  • Your uploaded files (PDFs, images, documents)
  • Financial input parameters (loan calculations, salary/tax inputs)
  • Personal identifying information (PII)

2. Cookies and Advertising Disclosures

QuickToolkit is provided free of charge to web users worldwide. To support infrastructure and continuous engineering, we may display third-party advertisements (such as Google AdSense).

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to your sites and/or other sites on the Internet. Users may opt out of personalized advertising by visiting Google Ads Settings (google.com/settings/ads).

3. Analytics & Performance

We may utilize privacy-preserving, aggregated telemetry to track general site performance metrics (such as page load speeds, error rates, and browser compatibility). This aggregate data does not contain personal information.

4. Contact Us Regarding Privacy
