privacytools.io is no longer the recommended one since the mod/domain owner split a long while ago, it now heavily endorses ads (such as nordvpn) you instead should use

Brave still is a great browser just disable a few settings as recommended in the guide

Be careful with the backups though, there’s a good chance you have 2FA enabled on your Google drive

So basically if you lose your phone you can’t access your 2FA app, if you can’t access your 2FA you can’t open your Google Drive, which means you can’t ever get the backup

Other than disabling 2FA I’m not really sure on the best approach to get around this
