Those sentences don't mean much legally. Every1 web site stores your 'position' as a visitor to the site, and your pattern of movement could be linked to data you've freely chosen to give that page. If you provide a server with an email address, that server may autosend you something. I consider your account files2 yours, but I can delete it too, so the rules protect us both equally.
The plan for Hypervariety is to tinker with it3. No warranty is expressed or implied.
