I want to publish a PAID app on the market but first I'd like to find out if it's possible to at least see an email address of each person who bought my app. I'd like a way of possibly contacting some of them (no, i don't want to send spam or such).
Is this possible? Someone told me that in Google Checkout you can see each buyers detailed information which also contains an email address. Is this true?
Please excuse the fact that it's not a programming question, but it's still related to software development.
Thank you very much,
Andrei
