ПочтаРоссии would “paste” into its memory anything you copied to the clipboard in other apps. This happens for no reason. Clearly, a big security concern if you copied some sensitive info to the clipboard prior to your using ПочтаРоссии. The developers should update it to stop this behavior! Until then, I’ll keep my rating to 1 star only. I see a response to another review that this is done to automatically copy tracking numbers. But there is absolutely no reason to do it in this manner - and spy on a lot of other sensitive info that may be in the clipboard. Just add a “Paste” button in ПочтаРоссии so that the user can choose to do it or not. This will be much better than auto-pasting.
Reply to the developer’s response: The problem is not with you keeping us in the dark. The problem is with you using this functionality for NO GOOD REASON, and asking us to simply trust you not to do anything nefarious with it. Just stop it. Let the user decide to paste things from the clipboard or not!
