Privacy-first architecture
How Browser Data Tools keeps tool input local
Browser Data Tools is designed so normal formatting, validation, conversion, encoding, decoding, counting, and inspection work happens in your browser instead of on a backend processing API.
Quick answer
For normal tool usage, Browser Data Tools downloads static website files and then uses browser-side JavaScript to process the data you paste or load from a local file. The project does not include a backend API that receives your tool input for processing.
Privacy workflow
- Your browser loads the static HTML, CSS, JavaScript, and assets.
- You paste text or choose a file from your device.
- The browser reads the file with the File API when file loading is used.
- The tool processes the input in the page or in a Web Worker.
- Copy uses the browser clipboard and downloads use Blob URLs.
What is intentionally avoided
- No account system is required for the tools.
- No login, profile, or tool-history database is included.
- No online save-result or share-result URL is included.
- No backend endpoint is used for normal tool input processing.
- No tool input is intentionally sold or reused as content.
What still makes network requests?
Like any website, the browser must request the static site files from the hosting platform. Future analytics or advertising integrations may also request their own scripts or measurement files if they are enabled and disclosed. Those requests should not contain the text you paste into the tool editors for normal processing.
Safe-use recommendation
Browser-only processing reduces risk, but it does not replace your company policy. Do not paste production passwords, private API keys, customer records, medical records, financial records, or regulated data unless your organization allows that workflow.
How to verify the claim
You can inspect the browser Network panel while using a tool. The verification guide explains how to do that step by step.
