Software - Get Whatsapp History from Android

[login to view URL] Please try to use your android to login this web-version whatsapp. Here is my situation: I am using web-version of whatsapp, and I need to backup all chat history everyday, I don't want to do it every day manually. Is there any method to backup my history to my server? 1) History retrieving has to be fast. 2) I have this idea: Set the whatsapp auto-backup at 8pm everyday, then the chat history will be stored at some folder in android, I can decrypt this file and get the history, and then upload this history to my server.

The chat browser can keep running even after retrieving, then I can retrieve again anytime I want. 5) After retrieving, the history can be saved as excel file or whatever file, then it will be uploaded to a dedicated server for data analysis. Data analysis part will be next phase. Simply saying, there is a backend, the history of each chat, it will be saved as an individual case after each uploading, and I can check the chat by clicking it.
