When you first create your Instagram account, anyone can see your profile on Instagram. Your posts will only show up in the feeds of people who follow you, but anyone will be able to see them by navigating to your profile or if they search for a hashtag you’ve used.

If you would rather make your posts private so that only your followers can see them, period, Instagram lets you do this. Go to your profile, tap the three-dots icon to bring up account settings, and turn on the Private Account option.
