If I could find a way to register the app without the need of the user emailing me the details then I would.

I was open source in the beginning on Source Forge and since know one was interested after a peroid of time I went solo and everything took off from there.

The email people send me is only so I can reply with a serial number and a license file, once thats done, there email is deleted, nothing is collected.

I will work on a privacy policy though, thank you.
