I also agree that Zuckerman will not give up. Sooner or later he will try to generate incomes from our personal data on Whatsapp.

I like Telegram a lot more, so I strongly suggest you to try it out if you have not done so. One good thing is that Telegram allows multiple accounts on the same device.

I have not tried Signal too, but I suppose as an alternative communication app, Telegram is already good enough for me.

Yes @tryp4vps 
soon it will happens again. and again because everyone who use android/smartphone will be trapped and no personal life for him. who knows telegram and signal not got our personal info they also need same permissions like WhatsApp and Facebook. they also need your call log, contacts, location, storage, etc.. however anyone announced it or spy without announcement.
