Blue ticks on WhatsAppindicate that the other person has read the message you sent. It informs you that your communication has been received. You won't be able to see the blue ticks if they've turned them off. This is due to the fact that they must maintain their privacy and do not want others to know when they have seen a message.

If you disable read receipts on your account, it affects the entire chat. Even if the other party in the chat has enabled read receipts.

For Android, here's how to disable read receipts:

• From the app drawer or the home screen, launch WhatsApp.
• Now select More from the menu (three vertical dots on the top right).
• Then select Settings from the drop-down menu.
• Go to Accounts now.
• Select Privacy from the drop-down menu.
• Finally, toggle the read receipts toggle to off.

For iOS, here's how to disable read receipts:

• On your phone, open WhatsApp.
• Now, on the bottom navigation bar, hit 'Settings.'
• Then tap 'Account,' followed by 'Privacy.'
• Turn the toggle next to 'Read Receipts' off now.
