About this site
A toolbox that runs entirely inside your browser. This page spells out what it is, what it stores, and how to check both for yourself.
What this is
A single entry point for the small tools you reach for often: every entry laid out under its group, ⌘K / Ctrl K to search, and pins and recents kept on one row at the top. Tools are registered through a config file — adding one means adding one object to an array.
Privacy and data
The site is a set of static files. There is no backend, no API, no analytics and no third-party script. Whatever you type into a tool is computed in the page and goes nowhere else — it is never sent anywhere and never written to a log.
What is stored locally

All of it lives in this browser’s localStorage under keys prefixed with `toolbox.`. Clearing site data removes every trace; there is no server-side copy to clear.
Network requests
Nothing is requested after the first load. The font is a self-hosted woff2, the background glow and grain are CSS and an inline SVG. No external image, no third-party CDN, no Google Fonts.
How to verify it yourself
Open the Network panel in devtools, tick “Disable cache” and reload: apart from this site’s own HTML, CSS, JS and that one font file, there should be no external request at all. You can also switch JavaScript off and reload — the content and the tool list stay readable.
