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: Go to Edit Flashcard Set page
On the main set page click "Edit" on the upper right.
Step 2: Change "Visible to: just me"
At the top of the Edit Flashcard Set 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.
