If I delete a message, will it be deleted for the other person too - briefly?
No, deleting a message on your end does not delete it for the other person. They will still see the message in their chat history unless they also delete it themselves.
If I delete a message, will it be deleted for the other person too - in detail?
When you delete a message in a conversation, whether it also disappears for the recipient depends on several factors. The primary considerations are the type of messaging platform and the specific features or settings activated by either party.
In many traditional messaging platforms, such as SMS or email, deleting a message from your end does not remove it from the recipient's inbox. Once a message is sent, it exists independently on both devices, and deletion on one side does not affect the other. This is because these systems are designed to ensure delivery and receipt of messages without ongoing synchronization after transmission.
However, modern messaging applications like WhatsApp, Messenger, or iMessage offer more dynamic functionalities. For instance, WhatsApp provides a "Delete for Everyone" feature that allows you to revoke a message within a specific time frame (typically seven minutes). If the recipient has not yet seen the message or if their device is offline during this period, the message can be removed from both devices. Similarly, in iMessage, you can delete messages from your conversation history, but it will only affect your own view; the recipient's copy remains unchanged.
Additionally, some platforms may offer end-to-end encryption, ensuring that messages are only readable by intended recipients. While this does not automatically delete messages on both sides, it enhances privacy and security.
In summary, while traditional messaging systems do not support mutual message deletion, many contemporary apps provide features to manage the visibility of sent messages for all participants involved in the conversation. It is essential to understand the specific capabilities of the platform you are using to determine whether deleting a message will also remove it from the recipient's view.
