However, this data area is not overwritten by new data or chats, which can be recovered by forensic and recovery software. When you delete any data, or chat, the app marks the said information as deleted. He also mentioned that the data could also be recovered from remote backups. However, in order to get the required data, one needs physical access to the device. He found that the app retains and stores a forensic trace of the chat logs, even if you are deleting them this creates a ‘treasure trove’ for those who are mining for data. Zdziarski’s findings open up the fact after he scrutinized the disk images from an iPhone with the new version of the WhatsApp. But you should know that messages that are not seen on your screen, are actually still present on the smartphone, and are not permanently deleted by WhatsApp.Ī recent finding from an iOS researcher Jonathan Zdziarski reveals that WhatsApp retains all your messages that you have been deleting. Whenever you clear (or delete) a message, or a batch of messages on WhatsApp, (be it an individual chat or a group message), they disappear from your screen immediately. However, there is one thing you should know for sure, and will be surprised. Since WhatsApp started End-to-End encryption on all messages on its platform, you would be sure that your sensitive and private messages are not being intercepted. If you are using WhatsApp for most of your communication, you should be careful on what you send on the platform.
