Settings and Privacy
There are many settings you can change on Instagram. To access your account options, go to your Profile, then tap the Gear icon. From here, you can access your liked posts, submit a support request, and more.
By default, the photos and videos you share on Instagram are completely public. This means anyone can access whatever you share—even people who don't have an account on Instagram. If you're uncomfortable with the idea of people you don't know viewing your posts, you can make them private. This way, only people you approve will be able to see your posts. To do this, go to your Profile, tap Edit Your Profile, then turn on Posts are Private.
