This web site is used by many people, including students and teachers.
I do collect a certain amount of information from the web connection,
and this information is stored in the puzzle. This information is
common to web connections and includes times, IP numbers, browser type,
and other similar information. This information is maintained as long
as the puzzle is maintained.
My web server captures log information which includes some of the above
information, as well as the referring URL. This information is maintained
for some period of time, typically about a month.
The "My Puzzles" link tracks puzzles via a "cookie" that is associated
with a particular computer. The cookie basically links to a random number
that helps tie the puzzles a person makes together.
The puzzles have a name field that the user can put anything they want in,
including leaving it blank. In addition, the users can type things into
the comment fields, as well as the words, and thus expose as much personal
information as they choose.
However, this site does not solicit or collect email addresses or other
identifying information (other than the above mentioned name field), and
I really have no intention of doing so as it does not help in generating
or debugging the puzzles.
If you are uncomfortable with the above information, then it is probably
best not to use this site.
