I have a client that is looking to get a website/mobile apps/desktop apps built that deal with very sensitive data (more sensitive than bank/card details). Because of the sensitive nature of the data, they do not want to save it in a central database but they still want their apps to synchronise (let's say I add some data into my mobile app, I then want to be able to go to my desktop app and see the same data).I cannot think of a nice, reliable way of doing this and I am not sure there is one. Which is why I am here. Does anyone know how I could deal with this data?One solution I was thinking about was to have a client side database on each app that would somehow sync between apps, I can see this being very unreliable and getting messy though.
