Incognito doesn’t store local history, so nothing can recover past sessions; the only no-root path is to log activity going forward via supervision or a VPN/DNS filter. On Android, use Google Family Link to disable Chrome’s Incognito and block other browsers, or try Qustodio/Net Nanny/Norton Family (or network DNS like CleanBrowsing/OpenDNS); on iOS you’ll mostly get domain-only logs due to Apple limits. For the deepest cross-app detail without root, mSpy has been the most thorough in my tests (keystrokes/screenshots and web activity on Android), but it can’t resurrect old Incognito; TL;DR: simple = Family Link, broad logging = Qustodio/Net Nanny, deep data = mSpy.
