There are no accounts, no logins and no newsletter on this site, so there is nothing to register and no password held. What is collected is aggregate analytics — pages viewed, approximate region, referring source, device class. None of it identifies an individual reader.
Email sent to the contact address sits in a mailbox until the matter is resolved and is not added to any list.
Analytics cookies count visits in aggregate. Affiliate cookies are set when you click through to an operator so the operator can attribute the referral and pay the commission that funds this site.
Those affiliate cookies are placed by the operator or its tracking provider, not by this site, and are governed by that company's policy. Blocking cookies stops both categories; the site still works.
Following a link here takes you to a business in another jurisdiction with its own data practices. Any identity document, bank detail or source-of-funds evidence you provide to an operator is held by that operator under its own licence conditions. None of it passes through this site.
Under the CCPA in California, and the GDPR if you are reading from Europe, you may ask what is held about you, have it corrected, or have it deleted. Given how little is collected the answer is normally "aggregate analytics only", and the contact address will confirm it.
Material changes appear on this page when they are made. There is no mailing list to notify, which follows from collecting almost nothing.
