Printed exactly as supplied, in the order supplied, with no labels and no ranking between them. This site runs no checks against any of them. It publishes no uptime figure, no status light and no date of last checking, because it never looks. An address that opens is not by itself evidence of anything.
The catalogue, page three
The end of the run, and the part most readers skip. These cards are about the machine in front of you and the people in the same building, which is where most private things stop being private.
What a reducer is, and what it is not
Every card ends with a numbered list of things that change the answer. Those are called reducers, and the word is doing careful work. A reducer changes how much a particular observer gets from a particular action. It does not remove the observer, it does not apply to the other six, and it is never a guarantee.
The temptation on a site like this is to write those lists as advice, in which case they slowly turn into a checklist and the site turns into something else. They are written as descriptions instead. Each one says what it changes, and then says what it leaves exactly where it was. Asking for a fresh circuit changes which relays are in the middle of a path. It does nothing to a record that a server already wrote, nothing to a file on a disk, and nothing at all to a parcel.
A few cards have three reducers and a few have six. The count is computed from the list, not typed in, so it is always the real number. Where a card has few, that is the honest answer rather than a gap. Some actions simply do not have five different levers attached to them, and inventing two more would be padding at the exact moment a reader is trusting the page.
The observers closest to you
The last two sections of the catalogue are the ones people find least interesting and should find most interesting. A device is the only observer in the list that sees everything without exception, because it has to render the page to show it to you. It is also the only observer that can be picked up, borrowed, repaired, sold or handed to somebody.
And then there are people. Not adversaries, and this site does not use that word about anybody you know. Just people with memory, who talk, whose circumstances change, and who are under no obligation to arrangements they were never told about. The most common way a private fact stops being private is not technical at all. Somebody said it, usually for a good reason, usually to one person.
If you have read this far, the two cards worth going back for are backups and sync and telling one person. Between them they cover more real exposure than the entire network section.
