If you've ever wondered who quietly unfollowed you on Twitter, you're not alone. Twitter doesn't notify you when someone hits unfollow, and the third-party apps that promise to track it usually demand your password or OAuth access — which puts your account at risk.
There's a safer way. Twitter lets you download a complete archive of your account, including your full followers and following lists. By comparing two of these archives over time, you can see exactly who left.
Why third-party tracker apps are risky
Apps that "watch" your follower count in real time work by signing in on your behalf and scraping the API. That's against Twitter's Terms of Service, and accounts that authorize these tools regularly get flagged, rate-limited, or suspended.
Even when an app behaves, you're handing over the keys to your account — your DMs, your ability to post, sometimes the ability to change your password. If the company gets breached or sold, your account goes with it.
The safe alternative: your own data export
Twitter (now X) is legally required to give you a copy of your data. The export includes your followers and following lists as plain .js files inside a downloadable archive. You don't need any special permissions, and the platform never knows you're using it for follower tracking.
Here's how to request yours:
- Open Twitter/X on the web and go to Settings and privacy → Your account → Download an archive of your data.
- Confirm your password and identity. Twitter will email you when the archive is ready — usually within 24 hours, sometimes faster.
- Download the
.zipfile when the email arrives.
That archive contains everything you need.
If you just want a quick one-shot view, drop the .zip straight into our free Twitter unfollowers checker — it parses the archive in your browser and shows you who doesn't follow you back, no login required.
Comparing two snapshots
A single archive only tells you who follows you right now. To find unfollowers, you need to compare two archives taken at different points in time.
The manual way:
- Open
data/follower.jsfrom your old archive and your new archive in a text editor. - Extract the user IDs from each.
- Diff the two lists — anyone in the old list but not the new one has unfollowed you.
This works, but it's tedious, and Twitter user IDs are just numbers — you'll need to look each one up to find out who they actually are.
Letting FollowerCleanup do the work
FollowerCleanup automates this exact workflow. You upload each archive when you receive it, and the tool:
- Parses your follower and following lists from the export
- Diffs each new upload against the previous one
- Shows a clean list of people who unfollowed you, plus their handles, display names, and avatars
- Flags accounts that look like ghosts (zero tweets, abandoned for years, empty profiles)
- Highlights people you follow who don't follow you back
Because everything runs on files you supplied, there's no API access, no password storage, and no way for your account to get flagged. It's the same data Twitter already gave you — just made readable.
How often should you take a snapshot?
Once a month is plenty for most people. Twitter caps how often you can request an archive (usually once every few days), so monthly cadence keeps you well within limits and produces a clear picture of who's drifting away. If you're running a brand or growth campaign, weekly snapshots will surface trends faster.
Final thought
You don't need to compromise your account security to know who unfollowed you. The official export route takes a little longer than a one-click app, but it's the only method that's safe, ToS-compliant, and ban-proof.
