how to know if someone opened your chat on whatsapp?

To confirm if your WhatsApp message has been read, follow these practical steps:

1. Check the Blue Ticks
   WhatsApp uses a tick system to indicate message status. When your message is sent, you see one gray tick. Once it is delivered to the recipient’s device, a second gray tick appears. When the message has been read, the ticks turn blue (assuming read receipts are enabled). If you see two blue ticks next to your message, it indicates the recipient has opened and read it.
2. Verify Read Receipts Settings
   Sometimes, the recipient might have disabled read receipts, which prevents blue ticks from appearing. To confirm whether the message has been read, check if your own read receipt setting is enabled. Go to Settings > Privacy > Read Receipts and ensure the toggle is turned on. Remember, if the recipient has turned off read receipts, you won’t be able to confirm if they have read your message.
3. Use the Message Info Feature
   On both Android and iPhone, you can tap and hold your message, then select ‘Info’ or ‘Message Info’. A new screen will show details like when the message was delivered and when it was read. If it displays a timestamp for ‘Read’, then the recipient has opened your message. If it only shows ‘Delivered’, they might have received it but not read it yet.
4. Look for Last Seen or Online Status
   If the recipient’s privacy settings allow, you can see their last seen or online status. If they are currently online and you see this status, they likely have your message open. But some users restrict this info, so you cannot rely on it always.
5. Be Aware of Limitations
   Remember that read receipts don’t work if the recipient has turned off read receipts or if you are in a group chat, especially if the settings are altered. Also, third-party apps claiming to verify message reads are often unreliable and can compromise your privacy.
