Running pretty similar setup too. I use synching and borgbackup though for sync and backups and mailbox.org as mail/caldav service Possible additions: - a free DNS service - signal or xmpp for messaging - open source password manager with self-hosted sync, I use password-store - maybe trivial: use different, strong passwords and 2-factor-auth where possible - use different mail-aliases for every service you register. Mailbox.org allows me to receiver any mail send to myaccountname+somealias@mailbox.org, that way if I get spam or my address is leaked I can know how gave it away in many cases - use lineageOS instead of stock android - install apps from f-droid when possible I have not found a good replacement for Google maps yet, especially on the phone when I need navigation.
