Build a privacy-first desktop product that processes the user's official Instagram data export locally, reconciles follower and following records, and separates active non-followers from deleted, deactivated, or uncertain accounts. It should produce an evidence-backed review queue with profile links, exclusions, checkpoints, and guided manual cleanup rather than promising unsupported profile-viewer data or uncontrolled bulk actions. The first version can be a paid one-time cleanup utility, followed by optional periodic audits.

Repeated paid-user complaints across multiple products show persistent demand alongside collapsing trust in credential-based trackers. A data-export workflow can provide transparent results without depending on fragile unofficial login access.
