There is one ad that pops up just before you enter your PW. Would be nice to have the ad AFTER, so no unauthorized person will see the ad. My other suggestion is allow renaming of the app so I can disguise it as something else. STILL I highly recommend it because it works. solves a big problem, In terms of privacy.
