If I delete a chat in WhatsApp, will the other person be notified - briefly?
If you delete a chat in WhatsApp, the other person will not be notified. However, they may notice that the chat has disappeared from their list of conversations.
If I delete a chat in WhatsApp, will the other person be notified - in detail?
When you delete a chat from your WhatsApp on your device, it does not notify the other party involved in the conversation. Deleting a chat is an action that only affects your local copy of the messages and media shared within that particular conversation. The other person will still have access to all the messages and files sent or received during the course of your interaction unless they also independently choose to delete their copy of the chat.
It’s important to note that while deleting a chat on your end removes it from your device, the conversation history remains stored on WhatsApp's servers and can be accessed by the other person if they have not deleted their copy of the chat. This means that if you are concerned about privacy or wish to ensure that certain information is no longer available, you should encourage the other party to delete the chat from their device as well.
Additionally, deleting a chat on your end will also remove it from any backups created by WhatsApp, provided backup settings have not been altered. However, if the backup setting includes chat history, then future backups may still contain messages from the deleted conversation unless explicitly removed from the backup as well.
In summary, while deleting a chat on your device does not send a notification to the other person and it removes the chat from your local view, the conversation history remains accessible to them until they also delete their copy of the chat.
