# Does Storage Studio read the contents of my documents?

Mostly it looks at sizes, dates and locations — not what your documents say. Measuring where space has gone, finding old folders and deciding what's safe to move only needs that kind of information, and it all stays on your Mac.

There are a few places where file contents are read, always on your Mac and only for a job you asked for:

- **Copying** a file to move or back it up means reading it.
- **Duplicates** compares files by their actual content to be sure two are identical.
- **Junk Yard** search can read text inside images you copied, on-device.

None of that is sent to us. See [Duplicates](https://storagestudio.us/manual/duplicates) and [Junk Yard](https://storagestudio.us/manual/junk-board) for how those features work.
