The quick notes works like this: it opens an instant scratchpad that autosaves to your browser's localStorage - no account, survives refreshes and crashes. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Where are notes stored?
In localStorage on this device and browser profile. Clearing site data deletes them - export anything important.
What happens if I clear my browser data?
The notes are erased with it, so anything long-term important should be copied out - the scratchpad is designed for session-scale capture, not archival.
