I've been using Nextcloud for a few years and it's great. The catch is that it's self-hosted so you'll have to get a VPS or have a Raspberry Pi lying around that you want to use for it. Setting up the server takes about 10 minutes if you're a technical user. It's just "sudo snap install Nextcloud" then some additional LetsEncrypt settings if you want SSL. I'll admit it's not a good solution for non-technical users who aren't familiar with the command line. However, multiple users can use the same server, so you can set it up once and share it with family members. You (the server admin) have full control over your data, so it won't be parsed and collected by third parties. It's also FOSS. There exist sync clients for all desktop and smartphone operating systems as well as a web interface for everything else. https://nextcloud.com/ https://nextcloud.com/
