Copy/paste passwords apps are not safe. Details clearly state that it clears the clipboard after your selected time interval has elapsed. It certainly DOES NOT. This is a well known issue for all Android apps. On my S5  opening Polaris Office and using the paste function shows my clipboard  nothing is cleared. Look for yourself. Passwords are visible in clear text & accessible by virtually any other app on your phone. Dev  just delete the false claim already  okay?
