How can a website read my folders?

Only with your explicit permission, through the browser’s file system access API. You choose which folder to grant, the browser enforces it, and nothing is read outside it.

Is anything sent anywhere?

No. The scan runs entirely in your browser — no file listing, no names, no contents leave your machine.

Can I delete things safely?

Deletions go to a restorable trash folder per location rather than disappearing, so a wrong call can be undone.
