Privacy Policy

1. Information collected and purposes

1. Information entered in the contact form (name (optional), email address (optional), type of inquiry, message): used only to respond to your inquiry, reply, and improve the Service.
2. Information to limit the number of submissions: to prevent abusive mass submissions, when the form is sent the sender’s IP address is turned into a hash value that cannot be converted back, and recorded on the server only for a short time (about one day). It is not used for any other purpose.
3. Server access logs: depending on the specifications of the rental-server provider, the access time, IP address and pages viewed may be recorded in logs. The Operator may use them to investigate failures and check for unauthorized access.

2. Information stored in your browser (local storage)

The following is stored only in your browser. It is not sent to the Operator’s server and the Operator cannot see it. If you clear your browser data, it is lost.

• Best scores and best times: Your highest records in the quizzes and map puzzles
• Puzzle difficulty: The difficulty you chose last in the map puzzle
• Furigana on/off: Whether Japanese reading aids (furigana) are shown
• Chosen language: The language you chose last (used to suggest a language on the language selection page)
• Analytics settings: Your “do not use analytics” setting, and, if you are in the EU, EEA, UK or Switzerland, your consent choice (the “do not use” setting is shared with the operator’s other sites, “47 Prefectures” and “Tokyo 23 Wards”)

3. Analytics (Google Analytics), cookies and advertising

To learn which pages and games are used and to improve the Service, the Service uses “Google Analytics (GA4)” by Google LLC. As a result, the following information is sent from your browser to Google’s servers.

• Information sent: the pages viewed (URL and title), the time and duration of the visit, the screens used (map, rankings, puzzles, quizzes and so on), where you came from (search, referrer), device, browser, OS, language and screen size, your approximate region (country or city level), and an identifier created with a cookie that does not identify you personally. Information that can identify you, such as your name or email address, is not sent.
• Recipient: Google LLC (Google’s servers in the United States and elsewhere).
• Purpose: understanding usage and improving the Service. It is not used for advertising (Google Signals and ad personalization are turned off).
• Cookies: _ga and cookies whose names start with _ga_ (identifiers that do not identify you personally), kept in your browser for up to two years.
• Visitors in the EU, EEA, UK and Switzerland: if your browser’s time zone suggests you are in one of these regions (or if it cannot be determined), a consent banner is shown at the bottom of the screen, and Google Analytics is not loaded and no cookies are set until you choose “Accept”. You can change your choice at any time with the button on the “About this site” page. In other regions no banner is shown, and you can opt out as described below.
• According to Google, GA4 does not log or store IP addresses. For how Google handles data, see Google’s Privacy Policy and How Google uses information from sites that use its services.

How to stop analytics (any one of these is enough)

1. Use the button below to choose “Do not use analytics in this browser” (saved only in this browser).
2. Turn on “Do Not Track” or Global Privacy Control in your browser (when it is on, analytics is not used automatically).
3. Install the Google Analytics Opt-out Browser Add-on.
4. Block or delete cookies in your browser settings.

Do not use analytics in this browser

Apart from this, the Service does not serve advertising or track users. It does not load map images or fonts from external services (only the Google Analytics script is loaded from Google).

4. Provision to third parties and transfers abroad

Except where required by law, the Operator does not provide personal information to third parties without the person’s consent. However, the analytics information in section 3 is sent to Google (and may be sent to and stored on servers outside Japan, such as in the United States). Inquiries reach the Operator by email through an email service.

5. Retention and deletion

Inquiries are kept only as long as needed to respond and are deleted when no longer needed. If you want what you sent to be deleted, please tell us through the contact form.

6. Children

The Service is designed with children in mind. When a child uses the contact form, please check the content together with a parent or guardian before sending. You can send a message without entering a name or email address.

7. Visitors from Europe, the UK and elsewhere

If you live in the EU, EEA, UK or a similar region, you can ask through the contact form (to the extent permitted by law) for access to, correction or deletion of the information obtained through the contact form, restriction of its processing, and withdrawal of consent. You can withdraw your consent to analytics at any time with the button on the “About this site” page; withdrawing does not affect earlier use. If you are not satisfied, you may also complain to the data protection authority of your country.

8. Links to other sites

The Service links to external sites such as data providers. The Operator is not responsible for how information is handled on those sites.

9. Changes to this policy

This policy may be changed when necessary. The changed policy takes effect when it is posted on this page.

10. Contact

Please contact us through the contact form. The Operator also posts announcements on X (formerly Twitter): とっと (@totto_ikukyu).
