do i have to use any foreground service type in manifest if it has no need?

I am working on scheduling app in which i am using foreground service , in below code i am using dataSync but there is no need of it on my project , i saw many developers are using at least 1 foreground service type thats why i have mentioned it , my question is if i removed it would it effect my app or it is ok

   Here is my code in manifest 
     <service android:name=".service.CountdownService"

        android:foregroundServiceType="dataSync"
        />
