About DevToolbox
DevToolbox is a collection of 38 small utilities for developers, spread across 8 categories. Every tool does one thing, loads instantly, and runs entirely on your machine.
Privacy
Whatever you paste into a tool stays in the browser tab. There is no backend, no database and no account system, so there is nowhere for your input to go.
Favorites, recent tools and your theme and language preferences are saved tolocalStorageon this device only. Clearing site data removes them.
There is no analytics or tracking of any kind.
