Short version: There really is nothing sneaky going on here.
Slightly longer version...
SiteSanity is a tiny company, not a big, faceless corporation. We will always aim to treat you as a human being deserving of respect and privacy.
We’re hosted on Digital Ocean VPSs, which are private to us.
The website uses Google Analytics to track visitor statistics (but not personally identifiable data). This is totally normal.
The newsletter / early access list uses Mailchimp if you sign up for that, which is a well-known and respected service that is not going to use your data in creepy ways.
No third-party cookies (aside from anything used by Google Analytics) or other craziness, and we respect your privacy too much to share or sell your email (or any other identifiable information about you) to any third parties.
In the words of Bill and Ted: Be excellent to each other.
