If I delete a chat in WhatsApp, will it be deleted for the interlocutor - briefly?
If you delete a chat in WhatsApp, it will not be deleted for your interlocutor; they will still see and have access to the conversation on their device.
If I delete a chat in WhatsApp, will it be deleted for the interlocutor - in detail?
If you delete a chat in WhatsApp, it does not automatically delete the same conversation for your interlocutor. Here is a detailed explanation of how this works:
When you delete a chat on your device, it is removed from your local storage. This means that the messages, media, and other data associated with that chat are no longer accessible to you. However, the deletion does not affect the content stored on your interlocutor's device or any backups they may have created.
The conversation remains intact on your interlocutor's end, and they can continue to access all the messages, media, and other data from that chat as if nothing had happened. They will not receive a notification about the deletion, and their experience with the app will remain unchanged.
It is important to note that while deleting a chat removes it from your local storage, WhatsApp still stores certain metadata related to the conversation on its servers. This includes information such as the date and time of messages, but not the actual content of the conversations. Therefore, even though the chat is deleted locally, some data about the interaction may still be retained by WhatsApp for internal use, such as analytics or troubleshooting purposes.
In summary, deleting a chat in WhatsApp only removes it from your device and does not affect the conversation on your interlocutor's end. They will continue to have access to all the data from that chat unless they choose to delete it themselves.
