The short answer: Threads won't tell you who unfollowed you, but you can see it yourself by comparing two exports of your own Threads data over time. Request your data through Meta's Accounts Center, upload it to WhoUnfollowed, and the exact names of who left show up in your browser in about two minutes. No password, no login, nothing sent to a server.
If you searched "who unfollowed me on threads" hoping for a built-in answer, there isn't one. Threads has no unfollowers tab, the same gap that has existed on Instagram for years. The method below is the closest thing to a real answer that actually exists.
Step 1: Request Your Threads Data Export
Threads doesn't have its own separate export screen. The request goes through Meta's shared Accounts Center, the same place Instagram and Facebook data requests live. Open Accounts Center from either app's settings, then go to "Your information and permissions," then "Export your information," then "Create export."
Select your Threads profile specifically, not Instagram. Each app needs its own separate export, even though the request flow looks identical. Choose "Followers and following" as the only category, set the format to JSON, and set the date range to "All time" so you get your full lists rather than only recent changes. Submit the request. Meta's own Help Center walks through this same export flow for Threads specifically, current as of September 2026.
Step 2: Download the ZIP
Meta emails a download link once the export is ready, the same way it does for Instagram. Download the ZIP without unzipping it. Selecting only Followers and Following instead of your whole account keeps the file small and the export fast to prepare.
Step 3: Upload It to WhoUnfollowed
Go to WhoUnfollowed's Threads page or drop the ZIP into the homepage upload zone. The file is read entirely inside your browser, using the same open-source parser (MPL-2.0) that already handles Instagram exports. Nothing is sent to a server. If you want to see who specifically unfollowed you, upload a second export from a later date and WhoUnfollowed compares the two automatically.
What You'll See
- Every Threads account you follow that doesn't follow you back
- New followers since your last export
- Mutual followers
- Unfollowers, once you have two exports to compare
Why No Password Is Needed
A quick search for "threads unfollower tracker" turns up plenty of tools that ask for your Threads or Instagram login before showing anything. That's the same risky pattern that has followed Instagram trackers for years: log in as you, pull data through channels Meta doesn't sanction for third parties, and put your account at risk if that activity gets flagged. WhoUnfollowed never asks for a password because it doesn't need one. The export file is already yours. We just read it, on your own device, using the same method used across the site for Instagram.
In Short
- Threads has no built-in screen showing who unfollowed you, the same gap Instagram has always had.
- Your Threads data export comes from Meta's shared Accounts Center, not a separate Threads settings menu.
- A single export shows who doesn't follow you back for free; comparing two exports over time reveals exactly who unfollowed you.
- Requesting the export is covered by your right to your own data under GDPR Article 20, the same basis Instagram exports rely on.
- WhoUnfollowed reads the file in your browser and never asks for your Threads or Instagram password.
Looking for Instagram instead? The same method works there too, just with a different export screen.
