You need to explain why you need to get permission to read my calendar and appointments. My personal information. ..
I have asked twice. No response

All permissions the app requests are completely legitimate and added with a specific purpose to enable a given feature. For instance, the reason the permission to read your calendar is needed is because the app has a feature to allow blocking calls when you have items in your calendar with a given keyword. You can find that option within the preferences section.
