Privacy & Security

How our local first architecture protects your data.

Privacy Policy

Last Updated: July 20, 2026

Your Data Never Leaves Your Browser

Traditional online tools require you to upload your files or text to their servers for processing. This website is different.

How it works:

  • WebAssembly (WASM): We use high performance compiled Rust code that runs directly in your browser's engine.
  • WebGPU AI: Our local AI engine (Gemma-2/Gemma-4) runs on your local GPU via WebGPU. Model weights are stored in your browser's IndexedDB and never touch our servers.
  • Universal Data & Batch Logic: Heavy computational tasks, including Universal Data Conversion and professional batch image processing, are handled entirely by client side Rust modules.
  • Local Execution: When you "Format JSON" or "Encrypt a File," the computation happens on your CPU/GPU, using your RAM.
  • Zero Network Requests: No data is sent to our servers. You can even disable your internet connection after the page has loaded, and the tools will continue to work perfectly.

Our Privacy Commitment:

We do not collect, store, or inspect any data you process. The only external connection made is to Google AdSense for monetization, which we have configured to prioritize contextual privacy.

Technical Audit: You can verify this by opening your browser's Network tab (F12). You will notice that no POST or PUT requests are made when you use any of our tools.

This clears LocalStorage, IndexedDB, and CacheStorage to return the site to its original state.
