Upload the data export Instagram already gives you and instantly see who doesn't follow you back, and who unfollowed you since last time. Nothing touches your account, so nothing can get it flagged.
Free first check · No credit card · You'll need the data export Instagram emails you
No Instagram login at any point. You download your own data and we read it for you.
In Instagram go to Accounts Center → Download your information → Followers and following. Pick date range All time.
Drop the file Instagram emails you. We only read the followers folder — your photos and messages never leave your device.
Your non-followers appear instantly, with search, Viewed tracking and CSV export.
Next week, next month — each new export is compared with the last one so you see exactly who left.

Logging in through a third-party app is exactly what gets accounts flagged. Instagram already lets you download your followers and following lists. That is all we need.

What people tell us after their first follow check.
“Two other apps wanted my password and got me a security warning. This one just reads the export.”
“The second upload is the useful part. I finally know who quietly unfollowed after my last collab.”
“The Not viewed / Viewed toggle turned 800 names into something I could actually work through.”
“Two minutes from download to my full non-follower list. No login, nothing to worry about.”
“Finally an unfollower tool that doesn't touch my account. That was the whole point for me.”
“Incredibly straightforward. Upload, wait a moment, done. My assistant handles it now.”
“The date-range warning caught my mistake before I panicked about hundreds of fake non-followers.”
“Super easy to use and the CSV export is exactly what I needed for my monthly cleanup.”
Built around the one thing other tools skip: your account is never touched.
We never ask for your Instagram login and never act on your account. You stay in control of your data from start to finish.
Every new export is compared with the previous one: unfollowers, gained and lost followers, with a reason where we can tell.
We only read the followers folder inside your export. Your photos, messages and everything else never leave your device.
The raw export is removed as soon as it has been read. Only the usernames needed for your results are kept, scoped to you.

No. FindUnfollower never logs in to Instagram, never automates anything and never touches your account. You download your own data export from Instagram and upload the file to us. That is a feature Instagram provides to every user, and reading your own copy of it cannot trigger a ban.
A non-follower is someone you follow who does not follow you back right now. An unfollower is someone who followed you in a previous export but no longer does. Your first upload shows non-followers; unfollowers appear from your second upload onwards, because we need two snapshots to compare.
Instagram's export defaults to “Last year”, which silently truncates your followers list to people who followed you in the past 12 months. Your following list stays complete, so the difference looks like hundreds of non-followers who actually do follow you. Choosing All time gives the complete list. We detect a truncated export and warn you before showing numbers.
Only briefly. Your browser extracts just the followers-and-following files and uploads those; the raw file is deleted as soon as it has been parsed. We keep the usernames needed to show your results and to compare future uploads, scoped to your account. Uploads that fail to parse are kept for up to 7 days so we can fix the bug, then deleted. Deleting your account deletes everything.
Coming soon. FindUnfollower works in any mobile browser today: request the export in the Instagram app, open the download link on your phone and upload the ZIP from your files app.
As accurate as Instagram's own export, which is the source of truth for your account. We compare the following list with the followers list exactly. The only common source of confusion is the date range described above, which we check for you.
