⚙️2. How Our Tools Work
Every tool on devtools.run is a static web page — an HTML file with embedded CSS and JavaScript. When you use a tool:
Your browser downloads the page once. After that, all computation happens locally using JavaScript running inside your browser tab. No data leaves your device at any point during tool use. When you close the tab, everything is gone.
This is by design. If you're pasting API keys into a JWT decoder, credentials from a config file into a formatter, or any other sensitive content into any tool — it never touches our infrastructure.
💡 You can verify this yourself. Open your browser's DevTools (F12), go to the Network tab, and watch while you use a tool. You'll see zero outbound requests while you type, paste, or format.
🍪3. Cookies
We use a small number of functional cookies — only to remember your preferences (such as your chosen indentation setting or dark/light mode). These cookies are:
| Cookie | Type | Purpose | Expires |
|---|---|---|---|
| dt_prefs | First-party | Stores UI preferences (indent size, theme). | 1 year |
We do not use advertising cookies, cross-site tracking cookies, or any third-party cookie services. We do not use Google Analytics, Facebook Pixel, or any behavioral ad network.
🔗4. Third Parties
We load one external resource: Google Fonts (for typography). When your browser requests a font file, Google's servers see your IP address. You can review Google's privacy policy for details on how they handle this.
We do not share, sell, rent, or trade your data with any third party for any purpose. We have no advertising relationships. We do not use any third-party analytics platforms that build individual user profiles.
If this site is ever acquired or transferred, any new operator would be required to uphold the same privacy standards described here, or notify users before doing otherwise.
