Frequently asked questions

Yes — who they followed or unfollowed, with timestamps, plus recent likes. Most apps skip likes; FlagUp shows them.
No. Private accounts are hidden from outside viewers. Instagram's privacy settings prevent access to follower lists and stories unless you are an approved follower. Only public profiles can be tracked.
