Where do the questions come from?
Questions are fetched live from the Open Trivia Database (opentdb.com) — a free, community-maintained trivia database with over 4,000 verified questions. A secondary API (the-trivia-api.com) is used as backup.
Is any data sent to a server?
The only requests made are to the public trivia APIs to fetch a question. No personal data is transmitted or stored by us.
Can I filter by category or difficulty?

What does the answer reveal button do?
Each question comes with the correct answer hidden. Click 'Reveal Answer' to see it. The answer is always fetched alongside the question from the API.
