WeChat was designed with your privacy and safety in mind. For this reason, WeChat does not store your chat data on our servers to make sure that only you and your intended recipient(s) can view your messages.

However, your chat data will always be available within the app on your device as long as the app is not removed and your phone has sufficient storage space.

If you wish to back up your chat log or transfer your chat log to a new device, use the Migrate Chats to Another Device or Favorites feature.
