Privacy Policy

Last updated: April 2026

The short version

Your data never leaves your browser. Period.

Data Processing

All DevToolKit tools run entirely in your browser using client-side JavaScript. No data you enter into any tool is ever transmitted to our servers or any third party. This includes but is not limited to:

• JSON, XML, YAML, or any other data you format or validate
• Text you encode, decode, or hash
• Passwords generated by our tools
• Regular expressions you test
• Any other input you provide to any tool

Local Storage

We use your browser’s Local Storage to save your last input in each tool for convenience. This data stays on your device and can be cleared at any time using the “Clear” button or your browser’s settings.

Analytics

We use privacy-friendly analytics to understand aggregate traffic patterns (which pages are visited, general geographic region). We do not track individual users, do not use cookies for analytics, and do not build user profiles.

Advertising

We display ads through third-party advertising networks. These networks may use cookies to serve relevant ads. You can opt out of personalized advertising through your browser settings or the ad network’s preferences.
