We can't trust apps from playstore anymore,100s of apps from play store are infected with malwares and keyloggers,do not download apps from play store anymore,if you need any app badly find their website and download from original source, beware
What most of these apps do is uploading users data to their own servers which can result in stealing your wallet keys too
when it comes to online nothing is safe so don't blame the Play Store only everything come under the internet is always care and we need to face them everything each and every day otherwise we don't need to use the internet that's why nothing is safe or private in this world.
