How it works

How to check who unfollowed you on Instagram

Your first import creates a baseline. Import a newer Instagram export later to see exactly which accounts stopped following you.

01

Export your Instagram data

Request your followers and following data in JSON format.
02

Import the ZIP locally

Select the ZIP. It is processed on your device and never uploaded.
03

See your lost followers

Import a newer export to compare snapshots and keep your history.

Common questions

What to know before you start

Can it show who unfollowed me before my first import?

No. The first import is your baseline. Changes appear after you import a newer Instagram export for the same account.

Do I need to sign in with Instagram?

No. You do not enter an Instagram password or connect an account. You only select the official data export you downloaded.

Does my Instagram ZIP leave my device?

No. The ZIP is processed in your browser and is not uploaded to a server.

Where is my follower history stored?

It stays in this browser. You can export a backup and restore it later on this or another device.
