WhatsApp will start sharing your information on Facebook, if you did not act now
WhatsApp update requests you agree to their new terms and condition.
(Which I believe most of us has done)
Try and read the terms and condition before agreeing.
Go to Settings > Accounts.
You will see that option to allow sharing of your information on facebook have been checked for you
You’re have just between now and September ending to change it (uncheck it) otherwise you will not be able to change it again.
Please be on the alert and inform others.
Its another attempt to start sharing your whatsapp information on facebook which you will not have control over anymore.
Act n Share.
