To turn off the blue ticks (read receipts) on WhatsApp, which indicate when you have read someone's message, follow these steps based on your device:

For Android Users

1. Open WhatsApp and tap the three-dot menu icon in the top-right corner.
2. Select Settings.
3. Go to Account > Privacy.
4. Find the Read Receipts option and toggle it off.

For iOS Users

1. Open WhatsApp and tap Settings in the bottom-right corner.
2. Go to Account > Privacy.
3. Toggle off the Read Receipts option.

Important Notes

• Disabling read receipts means you will not see blue ticks for messages you send either.
• Blue ticks in group chats will still appear even if you turn off read receipts.
• You can toggle this setting on or off anytime to control your privacy

Alternative Temporary Methods to Avoid Blue Ticks

• Airplane Mode: Turn on Airplane Mode before reading messages, then close WhatsApp and turn Airplane Mode off. This prevents sending read receipts temporarily.
• Notifications Preview: Read messages from the notification bar without opening WhatsApp.
• WhatsApp Widget (Android): Use the WhatsApp chat widget on your home screen to read messages without triggering blue ticks

This way, you can read messages privately without notifying the sender via blue ticks.
