Will the person see if I delete a chat in WhatsApp - briefly?
If you delete a chat in WhatsApp, the other person will not be able to see it on their device. However, they can still view the conversation history if they have backed up their chats.
Will the person see if I delete a chat in WhatsApp - in detail?
When you delete a chat in WhatsApp, whether or not the other person sees it depends on several factors. Firstly, deleting a chat from your device does not remove it from the other person's device. They will still be able to see and access the messages as they were before you deleted the chat. The chat history remains intact on their end unless they also delete the conversation.
However, there are additional features in WhatsApp that could influence visibility. For instance, if you use the "Delete for Everyone" feature within 7 minutes of sending a message, both you and the recipient will see "This message was deleted" in place of the original content. This applies to individual messages rather than entire chats. It's important to note that even with this feature, there is no guarantee that the other person won't have seen the message before it was deleted, as WhatsApp does not notify users when a message has been read.
Another factor to consider is whether you are using the "Disappearing Messages" feature. If enabled, messages in the chat will automatically delete after a set period (7 days by default). Once the time limit expires, all messages will be permanently deleted from both devices, and neither party can view them again. This feature applies to new messages sent after it has been activated; past conversations are not affected.
In summary, simply deleting a chat on your device does not affect what the other person sees. They will continue to have access to the conversation history as it was before you deleted it. However, using features like "Delete for Everyone" or "Disappearing Messages" can alter message visibility under certain conditions.
