    The Browser Sandbox

    Modern browsers (Chrome, Firefox, Safari) use a high-tech security feature called a 'Sandbox'. This ensures that a website can only interact with the data you explicitly provide it. ToolNet operates entirely within this legal sandbox. When you select a file, the browser 'grants' ToolNet's code permission to read that specific file and nothing else on your hard drive.

    This sandbox provides a dual layer of protection. First, it protects your computer from the website. Second, when combined with our local-processing architecture, it protects your files from the internet. The processing happens in a 'locked room' inside your browser where no outside entity can peer in. It's the most secure way to run complex code in a web environment.

    We constantly update our tools to leverage the latest browser security features, such as 'Cross-Origin Isolation'. This creates an even more secure environment for our high-performance WASM engines, preventing 'side-channel' attacks and ensuring that your document processing is isolated even from other tabs you might have open.

    Understanding the browser sandbox is key to understanding why ToolNet is different. We don't ask you to trust us; we use the established, multi-billion-dollar security infrastructure of modern browsers to guarantee your privacy. It's security you can rely on, powered by the software you use every day.

    Privacy is our Priority

    Like all our tools, the operations described in this guide happen 100% in your browser. No data is ever uploaded.
