Privacy Policy

Last updated: July 2026

devboxkit.com ("we", "the site") provides free browser-based developer tools: a JSON formatter/validator, Base64/URL/HTML-entity encoders/decoders, a UUID generator, a hash generator, a JWT decoder, a password generator, a JSON↔CSV converter, a Unix timestamp converter, and a regex tester. This page explains what data is and isn't collected when you use the site.

How the tools work

Every tool runs entirely in your browser using JavaScript. Anything you type or paste in — JSON, text, Base64, URLs, JWTs, timestamps, or regular expressions — is processed locally on your device and is never transmitted to, or stored on, any server operated by this site. Even the password and UUID generators use your browser's own cryptographically secure random number generator, so nothing about what you generate ever leaves your machine. Closing the tab discards everything.

Cookies and advertising

This site may display advertisements served by third-party ad networks, such as Google AdSense. These networks may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or generally at aboutads.info.

Analytics

We may use privacy-respecting analytics to understand aggregate traffic (e.g. page views, approximate location by country, device type). This data is not linked to the content you process on the site.
