Terms of Service
Updated October 3, 2026.
The game
WorldStudy is a free daily geography quiz. Every day at 00:00 UTC everyone receives the same ten countries; you have ten seconds per answer. Practice rounds are unlimited for Pro purchasers and are not ranked. There are no cash prizes, wagering or gambling of any kind.
Profiles
You can play as a guest without an account. Optionally, you can save your profile with an email address and a one-time sign-in code; the email is used only to restore your profile and is never shown publicly. You are responsible for the nickname you publish on the leaderboard. Profiles are not transferable.
Purchases
WorldStudy Pro is a one-time purchase of $2.50 that unlocks unlimited practice rounds. It is not a subscription. Checkouts and payments are handled by Paddle.com, which acts as merchant of record and charges applicable taxes. Pro is attached to your profile: it follows a saved profile when you restore it on another device, and it is removed when a purchase is refunded or charged back. See our refund policy.
Fair play
One ranked daily attempt per profile. Do not automate the game, create profiles to manipulate the leaderboard, resell Pro, or interfere with the service. We may remove scores, hide entries or refuse service for abuse. Determined players can still reconstruct the daily deck; we therefore do not offer prizes and do not claim certified competition results.
The service is provided as is
WorldStudy is provided "as is" without warranties of any kind. We may change, pause or discontinue features. To the maximum extent permitted by law, our liability to you is limited to the amount you paid us in the twelve months before the claim — usually $2.50.
Who is behind WorldStudy
WorldStudy is operated by a sole proprietor based in Serbia. Paddle.com Market Ltd is the reseller and merchant of record for purchases and handles order-related inquiries. For everything else — questions, profile deletion, refund requests — write to ilnur@klmln.com. Serbian law applies to these terms.
