Hide your account from search engines
Search engines such as Google and Yahoo may show your profile and boards in search results. You can hide your profile and boards by updating your search privacy in your account settings.
Hide your Pins from other people
While you can’t completely hide your active account, you can use secret boards to keep all of your Pins hidden from other people. Only you can view your own secret boards (unless you invite another person).
For extra privacy, you can change your name or use secret boards to keep your Pins hidden from others. Your secret boards can only be viewed by you and anyone you choose to invite to the board.
You can turn a public board into a secret board at any time. You can also move or copy a Pin to a secret board.
