However, Whatsapp says it won’t immediately disable accounts that don’t want to share their information with Facebook. The new policies are expected to take effect on May 15th, and WhatsApp will begin sending users persistent notifications to accept its updated privacy policies.
After a few weeks, the second stage is activated. At this point, the app will stop sending messages and calls to user phones. While the process will be different at this stage for users who do not accept the new policies, they will be left with limited options, such as exporting the chat history and deleting the account.
A separate policy, however, allows WhatsApp to automatically delete accounts after 120 days of inactivity.
