Automatically update web from WhatsApp

Read messages on WhatsApp, parse selected message for specific data and then update a website page with scraped information. This needs to be for Windows 11 and, if possible, quote also for apple apps (iPhone and iPad). Must include include piracy protection for windows and must be able to publish on apple store. It will have a free trial period (3 day at the moment). I do not expect more than 200 users max but they all know each other.
