App Records on iTunes Connect have a field for a privacy policy URL. The review guidelines don’t say much about it, though. I started with this generic privacy policy by Docracy, and edited it to be as short as possible. The result is https://vidr.io/privacy.
I wrote this because I'm releasing Vidrio on the Mac App Store. They want the URL of a 'privacy policy'. I don't know what should be in it. This post is my own, and not associated with my employer.
Jim. Public speaking. Friends. Vidrio.
