Privacy, Malware & Android Permissions
From a privacy perspective, any app that requires more permissions than its actual usage is not a secure or private app. Is there a valid reason why they would need your call information? Is the software related to managing calls? From what I can tell, not really. You can never trust developers for their words. Many people in the past claimed they will not spy or collect additional data even with permissions, many more people will do that in the future, yet there are a lot of them who do break their "promise".

I am personally relatively paranoid, so if an app is just a news browsing app, if it requires permissions like my SMS history or anything more than its initial purpose, It is a massive no go.
