If I delete a chat in WhatsApp, will it remain with the interlocutor - in detail?
When you delete a chat from your WhatsApp, the conversation is removed from your device and your view of the chat history. However, this action does not affect the messages on the other party's device. Your interlocutor will still be able to see the entire conversation history unless they have also deleted it from their end.
WhatsApp operates by storing messages locally on each user's device rather than on a central server. This means that when you delete a chat, you are only removing it from your own phone. The other person in the conversation will continue to see the messages and media exchanged until they choose to delete their copy of the chat as well.
It is important to note that while deleting a chat on your end removes it from your view, traces of the chat may still exist in the form of backups if you have enabled this feature. WhatsApp allows users to backup their chats to cloud services such as Google Drive or iCloud. These backups can contain deleted chats and may be restored at a later time.
In summary, deleting a chat on your WhatsApp will not delete the conversation from your interlocutor's device. They will still have access to the messages and media exchanged unless they too decide to delete their copy of the chat.
