Frequently Asked Questions

Everything you need to know about how QuizKite works, what it costs, and how we look after your data.

Is QuizKite really 100% free? What's the catch?

There is no catch. QuizKite is completely free — no paywalls, no premium tiers, no hidden subscriptions. Every quiz, article, and tool is fully accessible. We sustain the platform through non-intrusive, clearly-labeled advertising that never interferes with your learning experience.

Who writes the quizzes? Can I trust the accuracy?

Every quiz is researched, written and fact-checked by hand: we draft the questions and the plausible wrong answers, write an explanation for each one, and check the facts against reliable sources before publishing. We never auto-generate or scrape content from other websites.

Do I need to create an account to play quizzes?

No. You can play any quiz and read any article as a guest. Your XP, streaks, and history are saved locally in your browser. An optional free account unlocks cross-device sync, bookmarks, and leaderboard access.

Does QuizKite track my personal data or browsing activity?

No. QuizKite does not track personal browsing activity, sell user data, or use cross-site tracking cookies. We only use essential session cookies and non-invasive analytics. Read our full Privacy Policy for details.

How is a quiz scored, and can I try again?

You earn points for every correct answer, and there is no penalty for a wrong one, so it is always worth a guess. At the end you get a full review of every question with its explanation, and you can replay the whole quiz or practise just the ones you missed until they stick.

What subjects do you cover, and how often do you add quizzes?

Right now the library focuses on science and nature, geography, history and technology, and it grows as each new quiz is researched and written. We would rather publish a handful of quizzes we are proud of than flood the site with thin ones, so new sets are added steadily rather than in bulk.

Do I need to be online to play?

You need a connection to load a quiz, but once it is open everything runs in your browser, so a brief drop in signal will not lose your progress mid-round. Your scores, streaks and coins are saved on your device, and signing in keeps them safe across your phone and laptop.
