This is simple and free of legalese:
I don’t, and won’t, share your information with anyone, ever. My lists of users, emails, etc aren’t for sale or even visible (at least, if I’ve set things up correctly).
If I made (or make) a mistake and info gets out, I’ll do whatever I can to make it right. If you want to be removed from any list or system, there should be away to do it automatically but if not, just ask me.
That’s it. Nice and simple.
