When turning off sync in Google Chrome, there's an option called "Clear bookmarks, history, passwords and more from this device".

Will this do data erasure, so that the data is completely overwritten, or can it be restored from unallocated disk space?

Chrome tells your OS to delete the files. Your OS deletes the files.
That's it.

Conceivably on an encrypted SSD with Trim, then the data would eventually be wiped, but I wouldn't rely on it.

  • Just curious: How do you know? Is there a tool that shows what file-deletion requests the OS receives?

    @root - It's just common sense. If there is a tool that does that it would be against the rules to recommend it.

    @Ramhound It's not against the rules to state whether a tool exists. Nor to name one as proof.
