Why I Don't Use The Most Downloaded Caller ID Android Apk "Truecaller"?

According to the official report of Truecaller, there are more than 250 million people have downloaded this Caller ID Android Apk. I know most of you are using this Apk. It has a few awesome features. Right? But, I'm not using right now for a few reasons which I will share with you but before this, I'll share some best features of Truecaller.

Some Awesome Features of Truecaller:

[1] Blocking Number:

Using this feature you could block anyone's number. After blocking, if the person calls you, only a missed call alert will appear.

[2] Reduce of Spam Calls & Messages:

Spam Calls (ex: Customer Care, Advertisers, and other companies who calls you for their profit) will be blocked. Spam messages will not be delivered in the main Inbox.

[3] Know Unknown People:

If someone calls you, but the person's details are not available in your contact directory, then Truecaller will appear the person's name.

[4] Truedialer:

Truecaller app offers a dialer called "Truedialer". This looks so different and awesome than your default dialpad.

[5] Get Unknown Number Details by Searching:

You could know other person's details by searching his/her name or by searching his/her phone number. You can also see the profile picture of that person.
[6] Don't Need Internet Connectivity Everytime:

Once the unknown person's details appear using Truecaller, then there is no need of internet connectivity every time to know who is he. Whenever the person calls, his/her identity will appear whether there is no internet connectivity in your smartphone.

Why I Don't Use Truecaller Apk in my Smartphone?

A few months ago, I was the biggest fan of Truecaller. But, after knowing its business model, I uninstalled the app. Do you know how Truecaller earns?

[1] Advertisements:

It's OK. If someone providing us services and making money from showing advertisements, then OK. I have no objection.

[2] Data Sharing/Selling: 

It shares/sells users data with other countries advertising company. That means our privacy is not safe. We are being used by Truecaller. I love my privacy. That's why I uninstalled Truecaller Apk.

*If you love your privacy, then uninstall it.
