# WhoUnfollowed

> Privacy-first, open-source follower analysis for Instagram and Threads. Upload the data export Meta gives you and see who doesn't follow you back, who unfollowed you, and how your audience changes over time. Everything is processed in your browser. No password, no server, no Instagram or Threads API.

WhoUnfollowed reads the official "Download Your Information" ZIP that Meta provides for Instagram and Threads under GDPR Article 20. Instagram and Threads exports are analyzed separately, one profile per export. Unlike closed-source unfollower trackers, the entire web app is open source under AGPL-3.0 and the parsing engine specifically is MPL-2.0, so anyone can read the code and verify exactly what happens to their data instead of taking a privacy claim on faith. The free tier runs entirely client-side and needs no account.

Pro is a one-time unlock, not a subscription: $1.99 unlocks Pro for 30 days, $9.99 unlocks it for 365 days. There is no auto-renewal and nothing to cancel. When the time runs out, buy again if you want more. Pro adds unlimited snapshot history, unfollower detection across snapshots (who left, and when), cloud sync that is encrypted in the browser before it leaves the device, follower trend charts, and ghost-follower approximation. Email alerts and a mobile app are planned but not yet shipped.

- [Why Did My Ex Unfollow Me on Instagram? What the Timing Tells You](https://whounfollowed.co/blog/why-did-my-ex-unfollow-me-on-instagram): A stranger unfollowing you is nothing.

- [Do Businesses Need to Track Who Unfollows Them on Instagram?](https://whounfollowed.co/blog/do-businesses-need-to-track-instagram-unfollowers): A creator losing a follower is background noise.

- [Can Someone Tell If You Unfollowed and Refollowed Them on Instagram?](https://whounfollowed.co/blog/can-someone-tell-you-unfollowed-and-refollowed-them-instagram): You unfollowed someone, thought better of it, and followed them again a few minutes later.

- [Does Blocking Someone Count as Unfollowing Them on Instagram?](https://whounfollowed.co/blog/does-blocking-someone-count-as-unfollowing-them-instagram): Unfollowing changes your feed.

- [Can You See Who Unfollowed You on a Private Instagram Account?](https://whounfollowed.co/blog/can-you-see-who-unfollowed-you-private-instagram-account): Your account is private for a reason, so handing a random app your login feels worse, not better. Here is why seeing who unfollowed you works exactly the same on a private account, and why the safe method matters even more here.
- [Does Unfollowing Someone Remove Them as Your Follower?](https://whounfollowed.co/blog/does-unfollowing-someone-remove-them-as-your-follower): You unfollow someone, expecting a clean break. Instead they are still right there in your followers list. Here is why that happens: unfollowing and removing a follower are two completely different actions.

- [Why Your Instagram Instants Audience Keeps Shrinking](https://whounfollowed.co/blog/instagram-instants-mutual-followers-who-unfollowed): Instagram Instants only reach people who still follow you back.

- [Why Your Instagram Export Lists Accounts You Can't Find](https://whounfollowed.co/blog/accounts-in-instagram-export-you-cant-find): Your export says you follow them.

- [Does WhoUnfollowed Read Your Messages or Photos From Your Export?](https://whounfollowed.co/blog/does-whounfollowed-read-your-messages-or-photos-from-your-export): WhoUnfollowed's parser only ever opens four specifically named files inside your export.

- [Does WhoUnfollowed Store or Sell Your Instagram Data?](https://whounfollowed.co/blog/does-whounfollowed-store-or-sell-your-instagram-data): No, and the reason is structural, not a policy promise: WhoUnfollowed never receives your Instagram export in the first place.

- [Do "Who Unfollowed Me" Apps Actually Work?](https://whounfollowed.co/blog/do-instagram-unfollow-apps-actually-work): Every "who unfollowed me" app promises the same thing.

- [Instagram Follower Tracker Without Login: Do They Exist?](https://whounfollowed.co/blog/instagram-follower-tracker-without-login): Yes, but you have to know what to actually look for.

The ones that read your own data export cannot. Here is the difference.
- [Are Instagram Follower Trackers Safe?](https://whounfollowed.co/blog/are-instagram-follower-trackers-safe): Most are not. The ones that ask for your Instagram login put your account and your data at risk. Here is the checklist to judge any tracker, and the one model that is safe by design.
- [Is It Safe to Mass Unfollow on Instagram?](https://whounfollowed.co/blog/is-it-safe-to-mass-unfollow-on-instagram): Cleaning up who you follow is healthy. Doing it too fast, or with the wrong app, is how accounts get temporarily blocked. Here is where the line actually is.

- [Why You Still See Someone's Posts After Unfollowing Them on Instagram](https://whounfollowed.co/blog/why-you-still-see-posts-after-unfollowing-someone-on-instagram): The unfollow worked.

- [Does Unfollowing People Who Don't Follow You Back Help Your Reach?](https://whounfollowed.co/blog/does-unfollowing-non-followers-improve-your-instagram-reach): Instagram's own ranking documentation doesn't count your follow list as a reach signal.

- [Why You Lose Followers When You Change What You Post on Instagram](https://whounfollowed.co/blog/why-you-lose-followers-when-you-change-your-instagram-content-or-niche): You started posting something different, and the follower count dropped with no explanation from Instagram.

Here is the honest split between what is free and what is not.
- [What's Inside Your Threads Data Export?](https://whounfollowed.co/blog/whats-inside-your-threads-data-export): A Threads data export is a ZIP with a threads folder inside. Three files in it describe your followers and who you unfollowed. Here is what each one holds, what it leaves out, and why you never need to open it by hand.
- [Who Doesn't Follow You Back on Threads? How to Find Out](https://whounfollowed.co/blog/how-to-see-who-doesnt-follow-you-back-on-threads): Threads never shows you the accounts you follow that do not follow you back. One data export from Meta does. Here is how to get the list, what it includes, and what to do with it.
- [Does Threads Notify You When Someone Unfollows You?](https://whounfollowed.co/blog/does-threads-notify-when-someone-unfollows-you): No, Threads does not tell you when someone unfollows you, and it does not tell them when you unfollow either. Here is the full mechanism, the edge cases people assume differently, and how to find out anyway.
- [Can I Use My Instagram Export to See Who Unfollowed Me on Threads?](https://whounfollowed.co/blog/can-i-use-my-instagram-export-to-see-who-unfollowed-me-on-threads): No. Even though Instagram and Threads share the same export screen, they produce two separate files covering two separate follower lists. Here is why one export never covers both, and what actually happens if you upload a ZIP that has both inside.

## Key facts
- Fully open source: the web app is AGPL-3.0 and the parser is MPL-2.0, both public at https://github.com/al-kilic/WhoUnfollowed. Anyone can audit exactly how data is processed.
- No Instagram or Threads password is ever required. The tool reads a data export the user already owns.
- Supports Instagram and Threads. Threads exports use the same Accounts Center flow (JSON, All time, Followers and Following); only threads/followers.json, threads/following.json, and threads/recently_unfollowed_profiles.json are read.
- The free tier processes data entirely in the browser. Nothing is sent to a server, and no account is needed.
- Pro is a one-time unlock ($1.99 for 30 days, $9.99 for 365 days). It never auto-renews. For a limited time there is also a one-time Lifetime "Insider" option ($19.99, no expiry).
- Cloud snapshots, a Pro feature, are encrypted in the browser before they leave the device.
- TOS-compliant: it does not use the Instagram or Threads API and does not scrape either app.
- Core pages (home, pricing, compare, and a few guides) are available in English, Spanish, and Portuguese. See the Languages section above for the full list.
