Ideally, run your own node. The second best thing is to use a node ran by a friend or family member you trust. Anyone is invited to use my “friends and family” node to connect their wallets:

Host: monero.qertoip.com Port: 18081 (default)

Alternatively, if you know how to use your wallet over Tor:

Onion: blzchctiibfjfvtukctsydhquucz2oajnxnfc5hh4ix35gyqjhdnaqqd.onion Port: 18081

I take care to not log any activity, but I cannot guarantee about underlying hosting providers. You should always prefer connecting with VPN or Tor to any 3rd party service.
