You can now delete your Instagram directly from the mobile app. The Meta-owned social media app has now rolled out a new option that lets you opt to delete or deactivate your Instagram account on iOS in order to comply with Apple’s updated App Store Review Guidelines that now mandate all apps that offer account creation must also include account deletion within the app as well.

Until now, you had to log in to Instagram through a web browser on a desktop or mobile in order to delete your account. The company said it’s now introducing this option within its iOS app. Earlier you could deactivate the account through the app, but this doesn’t delete your data from Instagram’s servers. The app itself didn’t offer any information about the full deletion option, so many users may have simply deactivated their accounts instead of deleting them fully.
