Can I see who opened my chat on WhatsApp
WhatsApp does not provide a feature that allows you to see who has opened your chat or viewed your profile.
While you can see when someone was last online, this does not indicate that they have opened your chat specifically.
Additionally, the read receipts feature only indicates whether or not a message has been delivered to and read by the recipient, but it does not tell you when or how many times someone has opened your chat.
It's important to remember that privacy is a key feature of WhatsApp, and the app is designed to protect the privacy of its users. Therefore, if you want to know if someone has opened your chat or viewed your profile, you will need to ask them directly.
