# Does 'Available offline only' upload my files to Delta Drive?

No. With **Available offline only**, the files stay on your Mac and are never uploaded. Delta Drive learns only their names, sizes and dates, so you can see what's there from anywhere.

The contents are reachable only while that Mac is on. That's the point: it's the honest option for material you'd rather not store with us at all. On the web these items carry a differently coloured **Linked** mark, and may show **Last heard** if the Mac hasn't checked in for a couple of days.

See [the three modes](https://storagestudio.us/faq/delta-drive/what-is-the-difference-between-linked-folder-modes).
