There are no accounts, no logins and no newsletter on this site, so there is nothing to register and no credentials held. What is collected is aggregate analytics: page views, approximate region, referrer and device class. None of it identifies a 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 traffic in aggregate. Referral cookies are set when you click through to an operator so the operator can attribute the visit and pay the commission that funds this work.
Those referral cookies are placed by the operator or its tracking partner rather than by this site, and they fall under that company's policy. Blocking cookies stops both kinds and this site continues to function.
Following a link here takes you to a company in another jurisdiction with its own data practices. Any identity document, bank detail or source-of-funds evidence you give an operator is held by that operator under its own terms and its own licence conditions. It never passes through this site.
Under PIPEDA in Canada, and under the GDPR for European readers, you may ask what data is held about you, have it corrected, or have it erased. Because so little is collected the honest answer is normally "aggregate analytics only", and the contact address will confirm it.
Changes to this policy appear on this page when they are made. There is no subscriber list to notify, which follows directly from collecting almost nothing.
