The 100% Client-Side Processing Guarantee
Every calculation, string decoding, bit manipulation, and radix conversion performed on HexConverter.org takes place entirely within your local browser runtime. Zero input characters, numbers, text snippets, or cryptographic hashes are ever transmitted over the network or stored on any server.
1. How to Verify Our Privacy Claim in Your Browser
You do not have to take our word for it. You can independently verify our client-side guarantee using your browser's built-in developer tools:
- Open Chrome, Firefox, Safari, or Edge and press
F12(or right-click and choose Inspect). - Click the Network tab.
- Type or paste any value into our converter.
- Notice that no HTTP/WebSocket requests are sent as you type, compute, or clear results.
2. URL Hash Sharing (#v=...)
When you share a calculation using the URL hash (e.g. /hex-to-decimal#v=1F), the fragment following the # symbol is processed purely by your browser and is never sent to web servers in HTTP request headers.
3. Local Storage Usage
We use browser localStorage exclusively for storing your non-sensitive user interface preferences (such as your chosen word size: 8-bit, 16-bit, 32-bit, or 64-bit; and uppercase vs. lowercase preference). No calculation data or history is ever stored.
4. No Third-Party Tracking or Advertising Cookies
HexConverter.org does not employ advertising tracking cookies, marketing pixels (such as Facebook or Google Ads pixels), or behavioral profiling networks.
