Frequently asked questions
- 25 unique terms with no signup (Free Anonymous), and 100 with a Free Account — which also unlocks the full Pro feature set (logging terms as cleared, sentences, certificates, and your logbook), capped at 100 "Log as Cleared". Both lookup caps are lifetime. Revisiting a term you already looked up doesn't count — only first views deplete your quota.
- Yes — everything carries over. Your cleared terms, points, streak, levels, and any Aviation Literacy Certificates you earned on the Free Account stay exactly as they are. Going Pro simply removes the caps so you can keep going across all 25,000+ terms.
