Who is not following you back on Instragram?

Until now, you needed to install an application on your phone to identify instagram followers that are not following you back. The problem is that with the majority of those follow/unfollow applications, you need to provide the application your instagram credentials. You should never share your Instagram credentials with anyone because that puts your account at risk.
With WhoHasUnfollowedMe, you download your data legitimately through Instagram and load it into this page to determine who is not following you back.
We don't need your instagram credentials so there is zero risk to your account.
To select the correct data format and extract the required files, this tool should be used on a computer - not a mobile device.
