okay unironically one of the ways to counter online "subscription" services (aka SaaS - Software as a Service) is to learn how to host your own services. you don't have to go over the top with it like hosting your own netflix but you can do things like learning a bit of nginx configuration. Instead of using something like rocket money you can mess around with trying to host something like https://www.firefly-iii.org/ behind nginx. if you want to take it to the next step you can learn about things such as ZFS to make an encrypted dataset for securing that data. You don't have to go all out and make a profession out of it but by hosting a couple of services for yourself and maybe some close friends/family members you can save some money and learn a bit about sysadmin stuff in the process. Maybe you don't feel comfortable hosting financial stuff just yet, I'd recommend checking https://github.com/awesome-selfhosted/awesome-selfhosted out this list for a variety of cool software to host instead then to let you dip your toes in the water.
