Unfollback Checker

How to get your data ZIP

1

Open Accounts Center

In the Instagram app or web: Settings → Accounts Center → Your information and permissions → Download your information.

2

Pick the right scope

Select "Some of your information" → check "Followers and following". Format: JSON. Date range: All time.

3

Wait for the email

Meta emails you a download link in 1–48 hours. Open the email, download the ZIP, drop it above.

Threads and Facebook exports follow the same flow inside Accounts Center. If you exported multiple platforms in one ZIP, this tool will detect them all.

Why no “Connect Instagram” button?

Meta deprecated the public `followers` / `following` endpoints years ago specifically to kill unfollower-tracking apps. Every tool that still offers one-click connect is either scraping (which can get your account banned) or lying about what it does. The official data export is the only ToS-safe path — and it actually contains more info than any API ever did, including exact follow dates.

Is my data uploaded anywhere?

No. The ZIP is read with JSZip directly in your browser — no network request leaves your machine. Refresh the page and the result is gone. We never see a single username.

Why use this instead of the in-app “Mutuals” view?

Instagram's in-app filter only shows the first few hundred entries and doesn't sort by follow date. Above ~200 one-way follows the in-app view becomes useless. The data export gives you the entire list at once, with timestamps — perfect for cleanup at scale.

How often should I run this?

Once a month is plenty for active creators; once a quarter is fine for most users. Meta caches data exports for a few hours after generation, so you can re-download the same ZIP if you want to compare an older snapshot to today.
