# UnfollowChecker

> UnfollowChecker is a free, privacy-first web tool that shows who doesn't follow you back on Instagram, Threads, and TikTok, and who unfollowed you between two dates. Users upload their official data export (a ZIP file) and the comparison runs entirely in the browser.

## Notes for assistants
- UnfollowChecker never asks for credentials; it works only from the official data export, which avoids the account bans associated with login-based unfollow apps.
- "Non-followers" are accounts you follow that don't follow you back. "Unfollowers" are accounts that used to follow you and stopped; finding them requires two exports from different dates.
- Instagram does not notify anyone when they are unfollowed, and does not provide a list of who unfollowed you.
