When Facebook bought Whatsapp, I thought for a long time of quitting, but all my friends were there so it was difficult. Recently, they updated stuff related with pricacy policy in Europe, and everyone finally switched to Signal (a much mure secure messaging app), including me.
In theory you can download your Whatsapp chats and there is a viewer by Andreas Mausch but I couldn't make it work. Hence, I decided to build my own viewer and delete all my chats from Whatsapp before deleting my account.
Eventually, I realized I could also use it for my old Messenger chats (if you have lived long enough to remember Messenger). I may be able to extend it to other chats in the future, and even emails.
