Perp Reference · End matter · Updated: 24 September 2026

Reading an entry here leaves one record, the line the web server writes as it hands the file over. This
reference sets no cookie, runs no measurement or advertising code, keeps no accounts and asks a reader
for nothing. Those log lines are kept for 28 days and then deleted. Everything else is below.

An entry is a file on one server. Opening it fetches the page, the stylesheet, the icon and the two
typefaces the text is set in, every one of them from this domain, so reading here asks nothing of any
other host and tells no other host that you read.

## The seven parts of a log line

One line goes into the access log for each file sent, in the form any web server keeps by default.
Nothing of ours is added to it: no reader number, no mark placed on one visit and looked for on the
next.

| What the line carries | Where it comes from |
|---|---|
| The network address the request came from | the connection itself |
| The moment the request arrived | the server clock |
| The entry or file asked for | the request line |
| The status the server answered with | the server |
| The number of bytes sent back | the server |
| The browser or crawler string the request announced itself with | the request headers |
| The page a link was followed from, where a browser sends one | the request headers |

A line is kept for 28 days and goes when the log turns over; nothing is copied out of it
first. It does two jobs — keeping the entries reachable, and separating a reader from a script
asking for the same address a few thousand times an hour — and it is opened for nothing else.
No line is sold, let out for marketing, handed to an advertiser, read to work out who anybody
is, or matched against a record held anywhere else. A crawler is logged in the same file and
the same seven parts as a reader, and neither gets a record of its own.

## What this reference has no means of collecting

- No cookie is set or read by any entry, which is why nothing here stops a reader to ask about one.
- No measurement script, no tag manager, no counter, no pixel and no advertising identifier. This
  domain sits in no measurement or advertising account at all, so reading here cannot be lined up
  against reading anywhere else.
- Nothing on an entry takes typed input. There is no sign-in, no account, no comment, no rating, no
  newsletter field, no wallet connection and no search box, so there is no form whose contents this
  site could store.
- Nothing is fetched from elsewhere while an entry draws. The figures are drawn inside the page from
  the numbers printed beside them rather than loaded as pictures, and a finished page has spoken to
  one address, this one.

Publication on this site is paid for, and what that arrangement is stands in
[about this reference](/about). It is settled in money between the publisher and whoever is buying
the placement, and nothing a reader leaves behind here is any part of it.

## Links out of an entry

Every figure in this reference carries the address it was taken from — a venue's fee schedule, its
trading terms, a technical document, an audit record, a market data page. Those addresses are
printed as they stand. No referral code and no tracking parameter of ours is appended to one, and
nothing here sends a reader through a redirector, so following a citation reports nothing back to
this site.

What happens after the click belongs to the operator whose page it is, under its own policy and its
own cookies, and nothing in this entry reaches across to cover it. Following a citation is how a
figure on an entry gets checked, which is why the address is printed; taking the step is the
reader's decision and this site does not learn of it.

## Mail to the corrections address

One address is published, corrections@thekiddushclubnft.com, and it takes two things: a figure
you can disprove, and a question about this entry. Mail lands in an ordinary mailbox, and the
people who write the entries are the people who read it.

A message and the address it was sent from are kept while the matter is open and, where the answer
moved a figure, alongside the record of the day that entry was revised; ask at the same address for
either to be deleted and it is deleted. Neither joins a mailing list, because this reference runs
none. A log line is a different request: send the date of the visit and the address the connection
used, inside the 28 days, and the matching lines can be located, read back or wiped. Past that
point the record has already gone.

## Records from the earlier project at this address

This domain carried a project of a different kind before the reference existed, and that project
stopped. Nothing of it came across with the domain: no account list, no mailing list, no database,
no correspondence, and none of it has been sought since. Nothing from it is reproduced here and
there is no connection between the two.

A request for one of its old addresses is answered by this site's own not-found entry, which carries
the status a missing address should carry and points back to the front page and the contents rather
than to a blank page.

The maintainers are paid to publish this reference, and a venue with an entry here may be the party that paid for it.
