A private way to pass on information, without revealing who you are.
Free, from torproject.org/download. Works like any normal browser once installed.
Only opens inside Tor Browser, not a regular one.
Attachments are optional. You'll get a 16-digit code at the end, save it, it's the only way to check back later.
A normal website can see your device and rough location. Tor Browser hides that, this platform can't see who you are. That's the reason for the extra step.
Heads up: this page itself doesn't need Tor, you're reading it normally right now. Only the onion address above does.
