Instagram Privacy Settings & Information

Keep in mind that business profiles aren’t able to make their accounts private. If you want to make your business account private, first switch back to a personal account.
By default, anyone can see your profile and posts on Instagram. You can make your account private so that only followers you approve can see what you share. If your account is set to private, only your approved followers will see your photos or videos on hashtag or location pages.
