⚠️ Due to recent changes in Instagram's data policy, deactivated or deleted accounts are no longer included in follower data, so they may temporarily appear as unfollowers.

For an accurate analysis, be sure to set the period to 'All time' when you download your data.

❓ FAQ

Is this service trustworthy?
Feedbuddi never asks for your account details, the biggest cause of hacking and account theft, and only uses the official data you download directly from Instagram. Many unfollower-tracking apps can get accounts restricted, but we never send your data to a server and process everything only on your own device, which keeps the risk of hacking or data collection to a minimum. For transparency, our contact details are public, so feel free to reach out with any questions.

Are you worried the other person might find out?
Since Feedbuddi analyzes data that you personally download from Instagram, there is absolutely no way for others to know you are using it. We do not force access to your account from the outside, so you can use our service with peace of mind.
How accurate is it?
Data doesn't lie. Enjoy high accuracy with Feedbuddi's direct classification method. Regular updates are the most reliable way to maintain transparent social connections. Upload your latest data now and identify your hidden unfollowers.
Does Feedbuddi have a mobile app?
Not yet. An Android app is in the works. Until then, just open this page in your phone's browser (Chrome, Safari, etc.) and use it like an app.
Unable to select your ZIP file?
File selection may be restricted when using in-app browsers like those in KakaoTalk, WeChat, or LINE. If this happens, tap the menu at the top or bottom of the screen and select "Open in Browser," or directly open the Chrome or Samsung Internet app to access our site. You will be able to upload files normally through a dedicated browser.
