DevToolbox — Privacy Policy

Last updated: August 2026

DevToolbox is a Chrome extension developed by Qyntrax. This page explains what data the extension does and does not collect.

Data collection

DevToolbox collects no data of any kind. Specifically, it does not collect, store, or transmit:

• Personally identifiable information
• Browsing or web history
• Location data
• Authentication information
• Any content you type or paste into the extension's popup

How the extension works

All tools in DevToolbox (JSON formatting, Base64 encoding, JWT decoding, hashing, UUID generation, timestamp conversion, and case conversion) run entirely inside the extension's popup, using only your browser's built-in capabilities. Nothing you enter is sent over the network, saved to disk, or shared with any third party — closing the popup clears everything.

Permissions

DevToolbox requests no browser permissions. It does not read or modify the content of any web page you visit.

Third parties

DevToolbox does not integrate with, or send data to, any third-party service. The optional "Support on Ko-fi" link in the footer simply opens ko-fi.com/qyntrax in a new tab if you choose to click it; no data is passed to Ko-fi by the extension itself.
