I make some (well, one) Android Apps. They are all covered by this privacy policy:
Privacy Policy
My apps do not store any information about you.
My apps do not pass any information about you back to me. Whatever
data is collected (such as your location for my Avionics app)
is only used to provide functionality. That data never leaves
your phone
I will never sell any of your information
If I ever develop an ad-supported app, what the advertiser does will be governed by their privacy policy, as I will have no
control over it
