In this article, we will delve into the world of WhatsApp data recovery and explore the possibilities of recovering deleted chats.
Understanding WhatsApp’s Data Storage And Deletion Policy
Before we dive into the world of data recovery, it’s essential to understand how WhatsApp stores and deletes data. WhatsApp uses a client-server architecture, where all messages are stored on the user’s device and WhatsApp’s servers. When a user sends a message, it is stored on the sender’s device and WhatsApp’s servers. The message is then delivered to the recipient’s device, where it is stored locally.
When a user deletes a chat or a message, it is removed from their device and WhatsApp’s servers. However, the data is not immediately deleted. WhatsApp uses a process called “lazy deletion,” where the data is marked for deletion but not immediately removed. This allows WhatsApp to recover the data in case the user wants to restore it.
How WhatsApp Stores Data On Devices
WhatsApp stores data on devices in the form of databases and files. The databases contain information about the user’s chats, contacts, and messages, while the files contain the actual message content. The databases and files are stored in the device’s internal storage and can be accessed by WhatsApp.
When a user deletes a chat or a message, the corresponding database entries and files are marked for deletion. However, the data is not immediately removed from the device. The device’s operating system may still retain the data in its memory or storage, making it possible to recover the data using specialized tools.
