Privacy Policy

Last updated: 2026-05-12

Summary

DevToolbox does not collect, store, or transmit any personal data. All processing happens entirely in your browser.

100% Local Processing

All tools run client-side using JavaScript and Web Workers. Your data never leaves your browser — no server-side processing, no uploads, no API calls with your content.

Local Storage

We use browser localStorage solely to save your preferences (theme, language, sidebar state, pinned tools). This data stays on your device and is never sent anywhere.

Network Requests

The only network requests are for loading the application itself and, optionally, the "Fetch from URL" feature which proxies through our server without logging. No analytics, tracking pixels, or third-party scripts are loaded.

Cookies

DevToolbox does not use cookies of any kind — no session cookies, no tracking cookies, no third-party cookies.

Changes

If this policy changes, we will update this page. Since we collect no data, changes will likely only reflect new features.
