Very little. This is a static site with no accounts, no authentication and no comment facility. Privacy-respecting analytics record aggregate figures only — page views, approximate region, referring source — sufficient to establish which pages are read. No advertising profile is constructed and no data is sold under any circumstances.
Correspondence by email persists until the matter is concluded. That is the sole category of personal information held.
Operator links on this site are affiliate links. Following one may set a cookie placed by the operator or its network rather than by this site, enabling attribution of the referral. That cookie falls under their privacy policy rather than this one, and reading it before registering is a reasonable precaution, since from the point of click you are on their property.
No personal information regarding your activity there is ever transmitted to me. The report received is that a registration occurred, not who effected it. Blocking or clearing cookies terminates the mechanism entirely, with no consequence other than non-attribution.
Canadian privacy law, principally PIPEDA, entitles you to ask what personal information is held, to require its correction, and to require its deletion. In practice the holding is an email thread and nothing further. Request it and I will confirm and act without delay.
This site is not intended for anyone below the age of majority in their province, and information is not knowingly collected from minors. Notify me if you believe otherwise and the record will be removed.
