Never (Privacy Principles) ❌

Authentication & Live Data

• ❌ Instagram login/authentication — No direct Instagram API access
• ❌ Live data fetching — No real-time Instagram data requests
• ❌ Active follow/unfollow actions — No automated account actions

Data Collection

• ❌ Server-side processing — All processing remains client-side
• ❌ Profiling you from your export — it never reaches us, so nothing can be built from it
• ❌ Handing your export to anyone — it never leaves your browser. What the site’s own third parties do receive is spelled out below and in the Privacy Policy

Commercial Features

• ❌ Subscriptions — Finding your unfollowers is free in full, forever. The only paid item is a one-time $7 unlock for downloading the list as a file, and the download gives you a free sample first
• ❌ Paywalling the analysis — Every badge, filter and account stays free however large your export is
• ❌ Data monetization — No selling or monetizing user data, and no advertiser ever receives it

The site does carry advertising and affiliate links, which is how the free analysis is paid for. Ads are served by Google AdSense and cannot target your Instagram data, because that data never leaves your browser. See the Privacy Policy for what each third party does and does not receive.
