Nothing spooky here.
These days it's important to have a "privacy policy" available: so here's mine.
I do not collect information on individuals visiting this blog. If you leave a comment, I'll read what you wrote: but I don't keep a record of comments, apart from what Blogger displays. (In other words, the only record of what you write or who you are will be what people see at the bottom of the post.)
I do collect information about how many hits this blog gets, where they come from, and some technical information. I use the WebSTAT service for this purpose - and all that shows is which ISP you use, and where it's located.
You can stop most of Webstat's data gathering by disabling cookies in your browser. I don't know why you would, but some folks do.
I'm also an AdSense affiliate, so Google collects information on what I've written in each post: but that's mostly my problem.
I'm also considering starting an affiliate relationship with DAZ Productions. You should be able to keep DAZ and Commission Junction, their provider of affiliate services, from collecting information by - again - disabling cookies in your browser.
And you can keep DAZ Productions from finding out anything about you, by not buying any of their products.
Again, I don't know why you would: but some folks do.
Or, rather, don't.
