Common Questions

Frequently Asked Questions

Is it safe to use this unfollower tracker?

Yes! Unlike other apps, we don't ask for your login credentials. We only process the ZIP file from your own Instagram data export — nothing is sent to any server.

How often can I check my unfollowers?

As often as you like! Request a new data export from Instagram whenever you want to see the latest changes in your follower list.

Does Instagram know I'm using this?

No. Since you're downloading your own data and analyzing it locally, Instagram has no way of knowing you're using a third-party tool.
