What happens if you delete a user from WhatsApp - briefly?
If you delete a user from WhatsApp, all messages and media shared between you will be removed from your chat history. However, the deleted user's account and data will remain intact on their device.
What happens if you delete a user from WhatsApp - in detail?
When you delete a user from WhatsApp, several changes occur within the application. Firstly, the deleted user will no longer appear in your contacts list on WhatsApp. This means that any future messages or calls from this user will not be received by you. Additionally, all previous message history with the deleted user will be removed from your device. However, it is important to note that the data is not permanently erased; it remains stored on WhatsApp's servers until the other party deletes their copy of the conversation or until WhatsApp's retention policies are applied.
For group chats, if you delete a user who was part of a group, they will be removed from the group, but the group chat history will remain accessible to other members. The deleted user will no longer see any messages sent after their removal and cannot participate in the group conversations. If you are an administrator of the group, you might need to reassign administrative privileges to another member if necessary.
Furthermore, deleting a contact from WhatsApp does not affect their account or device. The deleted user can continue using WhatsApp normally and will be able to send messages and make calls as usual. However, they will not receive any responses from you unless they re-add your number to their contacts list.
In summary, deleting a user from WhatsApp results in the loss of communication history with that user on your device and prevents future interactions. The changes are limited to your experience within the application and do not impact the other party's account or data.
