Make a set private or public
Sets are public by default but you can make them private. If you've made a set private you can always make it public again by following the same steps.
You can make your flashcards private at any time. Private flash cards will not appear in search results and can only be viewed by the creator.
Step 1: Click on "Edit"
On the main set page, click "Edit" in the Tools section on the upper right.
Step 2: Change to "Visible to: just me"
At the top of the Edit page there are buttons for "Visible to" which by default is set to "everyone." Click on the "everyone" button to see a drop-down list of your privacy options. Select "just me."
Step 3: Save
Make sure to click "Save" at the bottom of the screen.
