Take back the control on your data, that’s the whole point… :) Where are you regularly saving data? Those are the prime candidates. Look at self-hosted alternatives for those services. I know big webapps hosted in docker containers managed by kubernetes is all the rage around here, but you can often find Unix style equivalent for such services, the main advantage of putting it on a server being to be able to access it from multiple devices. But you do you, if you prefer hosting big webapps, that’s fine too. :)
