DevToolKit is a collection of free online developer tools. All tools run entirely in your browser — no data you enter is ever sent to our servers or any third party.
We do not require registration or collect any personal information. We do not store, log, or transmit any text, code, or data you enter into our tools.
We may use Google Analytics to understand how visitors use our site. Google Analytics collects anonymous data such as pages visited and browser type. You can opt out via the Google Analytics Opt-out Add-on.
We may display advertisements via Google AdSense. You can opt out of personalized ads at Google Ads Settings.
All text processing, encoding, decoding, hashing, and formatting happens client-side using JavaScript in your browser. Your data never leaves your device. We have no ability to see, access, or recover any data you enter into our tools.
