Hello PH, I want to share my old project with you. It is a Chrome Extension and it provides a simple solution for your Web WhatsApp usage. You can use this extension if you think need some privacy when you need to open your WhatsApp on the Web during a meeting, in your office, or in a cafe. Also, it is an open-source project, you can review codes and make your special changes. Moreover, I added a message storage feature to the extension, If your Web WhatsApp is open SWW will store your incoming messages in your browser and you can see deleted messages from here. Thanks.
