There are many ways Google (and many others) know what you’re up to and where you are besides your internet browsing history.

It’s called metadata, and John Hancock can be proven to have been “in the hood” when the Declaration was signed…

GPS, wifi, cell pings, your neighbours, friends, their histories, their meta.

If you’re concerned about hiding your browsing history from a peer, a vpn is fine.

If you want to swat someone, then maybe not.

For file sharing

X-plore

has ssh, webdav, can scan for nfs & cifs shares.

Terminal

Termius

ssh, sftp, terminal, etc also, for backups, there’s a sync to desktop feature, plus rsync…

For torrents I use Real-Debrid (web, app is wonky)

Stremio works well, but you’ll need an RD account or it’s moot.
