How to Delete your WhatsApp Account?

 

You can't regain access to your account. It may take up to 30 days from the beginning of the deletion process to delete your WhatsApp information. Copies of your information may also remain after the 30 days in the backup storage that we use to recover in the event of a disaster, software error, or other data loss event. Your information isn't available to you on WhatsApp during this time. 

It doesn't affect your information related to the groups you created or the information other users have relating to you, such as their copy of the messages you sent them. 

WhatsApp may retain certain log data in databases even after you delete your account, but such data will be disassociated from any identifying information such that it can no longer be linked to your account. To do this, on a regular basis, WhatsApp wipe certain identifying information from this log data, and replace any instance of your account ID with a replacement identifier which cannot be linked back to your account once it is deleted.
