Track Instagram Unfollowers Without an App

Instagram doesn't keep or show you a history of who unfollowed you, and a single data export doesn't contain one either: it is a snapshot of your followers at the moment you request it. To see who left, you have to compare two snapshots taken at different times. NomeSigueApp does that for you in your own browser, with no app and no password: it saves a local snapshot of your lists and, the next time you analyze a newer export, it shows what changed.

Why one export can't tell you who left

The followers_1.json file in the export lists the accounts that follow you today, each with the date it started following you. An account that no longer follows you simply isn't there: nothing marks that it was once present and left. The same goes for following.json and the accounts you follow.

So the question "who unfollowed me?" only has an answer if you hold two lists from different moments: the one you had before and the one you have now. Anyone in the first list but not in the second has unfollowed you. Doing that subtraction by hand across thousands of names is tedious, and that is where the local history comes in. If you just want the basic method, see the guide on how to see who unfollowed you.

How the local history works

Each time you analyze an export, the tool saves a snapshot of your lists in the browser itself. It is never saved on a server. When you later analyze a newer export in the same browser, it compares the two snapshots and shows the changes since the previous date:

• Who unfollowed you.
• Who is a new follower.
• Who you stopped following.
• Who you started following.

There is no account and no sign-up: the history lives in your browser and you can delete it with a button whenever you like.

A simple routine, step by step

What matters is regularity, and always using the same browser and device.

1. Request your export: profile → menu (three lines) → Accounts Center → Your information and permissions → Download your information → Download or transfer information → your account → Some of your information.
2. Tick only Followers and following, choose Download to device, format JSON and date range All time.
3. When the email arrives, download the ZIP. If timing worries you, see how long Instagram takes to send your data.
4. Upload the ZIP as it is to NomeSigueApp. The first time there is nothing to compare: it only stores the snapshot.
5. Repeat every so often, as frequently as you like (weekly, monthly), always in the same browser.
6. From the second analysis on, you'll see the changes since the previous one.

It helps to note down the date of each export. Since the history only compares against the previous analysis, the further apart your exports are, the more changes you'll see at once and the harder it is to tell when each one happened.

What "unfollowed you" covers, and what it doesn't

The history detects that an account was in your followers list and is no longer there. That isn't always a deliberate unfollow. These cases look identical:

The export doesn't distinguish between the three, so the tool can't either. To find out what happened, open the profile: if the account no longer exists, you know it wasn't an unfollow. For the other cases, the tool can't tell you.

Limits worth knowing

• It only works in the same browser and device. If you analyze the first export on your phone and the second on your computer, there is nothing to compare.
• Private browsing saves nothing. When you close the window, the snapshot is gone.
• Clearing your browser data wipes the history. That is the price of nothing being stored on a server.
• It needs at least two analyses. The first one only creates the snapshot.
• It isn't a log of exact dates. It only compares two moments.

Frequently asked questions

Can I see who unfollowed me without installing an app?

Yes: by comparing two official exports taken at different times. NomeSigueApp automates it in the browser, with nothing to install and no password required.

Where is my history stored?

In your own browser's storage, never on a server. That keeps it private, but it also means it is lost in private browsing or when you clear browser data, and it doesn't travel to another device.

Can I see the exact date someone unfollowed me?

No. The export doesn't include that date. You can only know it happened between two analyses. What it does include is when each relationship started.

How often should I request the export?

Whatever suits you: further apart means more accumulated changes, more frequent means more detail about when each one happened. Keep in mind that Instagram may take a while to prepare the file.
