Apps offering free data or money based on using and sharing I have been hearing about some android apps which give you free money or data by installing, using and sharing. Many of my friends have been asking me to install such apps so-that they get benefits of sharing app with trying to convince me like "share to others and get free benefits". Such apps also gives benefits if you install other apps or click on some links through them.

But I've been refusing to install or use such apps thinking following reasons:


It should be nothing but pure advertising app for app maker
It may get our personal information like email, phone, contacts and even some may get usage and information of other apps, files etc.


But/Now, I want to know more about such apps like how do they work? what are the major and possible disadvantages (malicious, spy etc.) of using such apps, etc. so that I can keep way from  possible temptation/seduction and can preach my friends with better understanding.
Your concerns are 100% valid!

A few things you can consider while making a decision whether to install such apps:

-Firstly, do you really need this so called app? If not, don't install!

-Secondly, see if the app has any good/social cause which really helps people if you download the app (when i say help, i dont mean your friends getting free money), if it does, then consider helping out!

-Lastly, if you do choose to install the app, check the permissions the app is asking before installing. Try not to download from unknown sources, and do read the reviews. If you have Xiaomi phone or cyanogenmod/lineage, they usually have 'App Permissions' sections, make sure not to give the application any permissions!
