The keys are staying on the device, so I have no way to check if people actually entered them. I'm also not running any analytics. I mean, I just guess that if people weren't using the app, they would uninstall it eventually? I've had a retention rate of 60% which I thought was pretty good and made the think that people actually use the app. That being said, I completely understand the trust issue you mention. It's even worse for the online version of the same service, iamproxy.com Do you have a suggestion how I can improve the trust?
