Terms of Service

This is an English translation of the Japanese original. If the two differ, the Japanese version prevails. These texts are based on a general website template and have not been reviewed by a lawyer.

These Terms of Service (the “Terms”) set the conditions for using “World Playground” (the “Service”), provided by the operator of “World Playground” (the “Operator”). By using the Service you are deemed to have agreed to these Terms.

Article 1 (About the Service)

  1. The Service is a free website for learning about the countries of the world through maps, rankings, quizzes, map puzzles and more, based on publicly available statistics and map data.
  2. The Service is an unofficial educational site. It is not created or provided by the data providers (such as the World Bank), the United Nations or any government.
  3. The Operator may add, change or end any part of the Service without notice.

Article 2 (Data and content)

  1. The sources, licenses and indicators of the data used are listed on About this site and its data sources.
  2. The Operator tries to display data accurately, but does not guarantee that it is accurate, complete or up to date. Rankings use the latest value available for each country, so the year differs between countries, and values may include estimates and projections.
  3. Borders, capitals, the range of countries and the spelling of names are shown for reference only and do not express a position on disputed territories or similar matters.
  4. The translations into 17 languages may contain mistakes or unsuitable expressions. If the Japanese and another language differ, the Japanese prevails.
  5. When accuracy matters, for example in classes, presentations or publications, please check the original data.
  6. You may not present the content of the Service as if it were created or published by a country, an international organization or a data provider.

Article 3 (Prohibited acts)

You must not:

  1. violate laws or public order and morals;
  2. cause, or risk causing, disadvantage or damage to the Operator, other users or third parties;
  3. interfere with the operation of the Service (for example mass access or automated scraping that overloads the server, unauthorized access, or probing for vulnerabilities);
  4. use the contact form for spam, harassment, advertising or solicitation;
  5. impersonate the Operator or a third party;
  6. publish the content of the Service in a false form (for example altering the data and presenting it as the Service’s numbers); or
  7. do anything else the Operator considers inappropriate.

Article 4 (Your records)

  1. The Service has no registration or login.
  2. Records such as best scores and best times are saved only in your browser (local storage) and are not sent to the Operator’s server. If you clear your browser data, the records are lost.
  3. The Operator is not responsible if records are lost or cannot be carried over to another device or browser.

Article 5 (Rights)

  1. The copyright in the Service’s programs, design, text and translations belongs to the Operator. Data, maps and flags follow the rights and licenses of their respective providers, and the open-source software used follows its own licenses (see About this site and its data sources).
  2. Personal and educational use (showing it in class, playing at home, and so on) is free.
  3. If you build something else from the data of the Service, please credit the original sources and state that the data was processed.
