As an e-commerce platform, Pinduoduo has taken data protection measures to protect users' privacy and data security, including regularly deleting some historical orders and other data. Once the order is deleted, the relevant data is completely cleared and cannot be recovered.

It is necessary to keep order records. It is recommended to take screenshots or save the order information in time when receiving the order. At the same time, before placing an order, you can also choose to send the order information to the mailbox or SMS for backup.
