WhatsApp’s Privacy Policy Updates

Recently, WhatsApp tried to update their privacy policy which was actually about “WhatsApp with Business”. This is what new policy meant :

” All the WhatsApp messages are end-to-end encrypted. That means they can only be read by sender and receiver.

However, if a business choose a third-party hosting service (like Facebook), then the 3rd party can read those conversations.

This is completely optional for businesses. If a business sets Facebook as their hosting service, only then, Facebook will be able to read conversations like any other 3rd party hosting service. “

But, the policy got misunderstood and there was quite a rage about this changes, therefore, WhatsApp decided to postpone the said update.
