Very little. This is a static site with no accounts, no logins and no comments. Privacy-respecting analytics record aggregate figures — page views, rough region, where a visit came from — so I can tell which pages are actually read. There is no advertising profile being built and nothing is sold to anyone.
If you email me, that email and my reply exist until the conversation is finished. That is the only personal information held anywhere.
The links to casinos on this site are affiliate links. Following one may set a cookie placed by the operator or its affiliate network — not by me — so the operator can credit the referral. That cookie is covered by their privacy policy rather than this one, and reading it before you register is a reasonable habit, because from the moment you click through you are on their property.
I never receive personal information about what you do once you are there. I am told that a signup happened, not who made it. Clearing or blocking cookies in your browser stops the whole mechanism, with no consequence other than this site not being credited.
Canadian privacy law, principally PIPEDA, gives you the right to ask what personal data is held about you, to have it corrected, and to have it deleted. In practice the answer here is almost always an email thread and nothing else. Ask and I will confirm and act promptly.
Nobody under the age of majority in their province should be using this site, and information is not knowingly collected from minors. If you think a minor has been in touch, tell me and the record goes.
