Will the interlocutor see that the chat in WhatsApp has been deleted - in detail?
Deleting a chat in WhatsApp can have varying effects on whether your interlocutor will be aware of the deletion, depending on several factors.
Firstly, it is important to distinguish between deleting a message and deleting an entire chat. When you delete a message within a chat, WhatsApp provides two options: "Delete for Me" and "Delete for Everyone." If you choose "Delete for Everyone," the message will be removed from both your device and the recipient's device. However, there is a time limit of 1 hour, 8 minutes, and 16 seconds after sending the message to use this option. After this window, only "Delete for Me" will be available, which removes the message solely from your device.
In the case of deleting an entire chat, the process is different. When you delete a chat, it removes all messages and media from both your phone and the recipient's phone. However, this action does not notify the other person that the chat has been deleted. The chat will simply disappear from their device as well, similar to how it would if they had deleted the chat themselves.
Additionally, there are no indicators or notifications sent to the other party when a chat is deleted. They will only notice that the chat has disappeared if they attempt to access it. If the conversation was archived rather than deleted, the interlocutor would still be able to see the chat under their Archived Chats section.
In summary, while deleting messages can have visible effects depending on the option chosen, deleting an entire chat in WhatsApp does not send any notification or alert to the other party. The chat will simply vanish from both devices without any indication that it was deliberately deleted by you.
