Privacy

The short version: what you type into a tool stays on your device unless you export it.

What the tools store

Each tool saves your entries in your browser's own storage (IndexedDB) on this device. We have no server that receives them and no copy of them. Clearing your browser's site data, or using a private window, removes them, so use a tool's export button if you want a copy you control.

Links

Some tools can put settings in a link (after the # sign), such as an example in an article or a calculation you choose to share. Browsers don't send that part of a link to our server. Tools never put your entries, notes or history in a link, and whoever you send a link to can see what's in it.

What we can see

Nothing beyond the basic request logs our hosting provider keeps for running the site. We use no analytics.

There are no cookies, no ads and no third-party scripts.
