Metamask stores your private keys using your browser's data store. The source code of Metamask is auditable, like Parity and MyEtherWallet, by downloading from a repository (which you can then be more assured that the program you are running has indeed been looked at by other people -- unless someone is man-in-the-middle attacking you) or by unpacking the Chromium extension you downloaded.

Using Chrome on a Mac, your data is stored in ~/Library/Application Support/Google/Chrome/Defaults/Extensions.

To find which directory it is in, you can do a search grep -rw 'metamask' *. This will search for all instances of the word "matamask" within these folders.

  • TIP: The flag `-l` (lowercase L) in grep return just the filename, so `grep -rwl 'metamask' .` will give a quieter output. – Robino Jul 11 '23 at 19:04
