利用規約

Privacy Policy (English)

This is an English translation of the Japanese policy above. If the two differ, the Japanese text prevails.

株式会社なりたんこーぽれーしょん (the "Operator") sets out below how it handles information about users of Probably Yes (「たぶんはい」, the "Service").

1. Information we collect

  • Information received when you log in: the email address and identifier of your Google account. We also receive your name and profile picture from Google, but the Service does not display them.
  • Information you enter: your nickname and avatar image.
  • Paid plan information: your customer number at Stripe, and the status and period of your subscription.
  • Play records: the text of the questions you enter, the answers to them, the number of questions, the time you solved the puzzle or gave up, and the country you started playing from (only the country inferred from the connection; the IP address is not recorded) and the language of the screen. If you are not logged in, these are recorded against an anonymous identifier stored in your browser.
  • Encore page views: if you are logged in, the date and time you opened the Encore (paid plan) pages, and which page. Used to improve the Service and to decide what to offer.
  • Cookies: cookies that keep you logged in, the anonymous identifier, temporary cookies used during login, and cookies for analytics and advertising.
  • Connection logs: your IP address, browser type, time of access and similar information recorded automatically by servers and infrastructure.
  • Analytics information: pages viewed, time spent, actions taken, approximate region, and the type of device and browser, as collected by Google Analytics. This is not linked to your name or email address.

2. How we use it

  • To provide the game (judging answers, saving progress, showing the leaderboard).
  • To log you in and confirm who you are.
  • To deal with inappropriate images and abuse.
  • To investigate faults and improve the Service.
  • To understand how the Service is used (for example, which pages are viewed and how often).
  • To show advertising.

3. Sharing with outside services

The Service uses the following outside services and passes them information to the extent needed for each purpose. All of them include servers outside Japan.

  • Supabase: managing logins, and storing nicknames, play records and similar data.
  • Cloudflare: delivering the Service, and storing and delivering avatar images. Cloudflare Web Analytics is also used to count the pages viewed, the approximate region and page load speed. It does not use cookies and does not collect information that identifies you.
  • Google: login.
  • Cloudflare Turnstile: on the paid plans, this may be used to check that the Service is not being operated automatically by a program. During the check, your IP address and browser information are sent to Cloudflare.
  • TypeSafe AI (via OpenRouter): to judge the answers to your questions, we send the text of the questions you enter and information about the word. We do not send information that identifies you.
  • OpenAI: to check that uploaded avatar images are not inappropriate, we send the images.
  • Stripe: payment for the paid plans. Card numbers and other payment details are handled by Stripe and are not held by the Operator. The Operator receives your customer number and the status of your subscription.
  • Google AdSense: used to show advertising. Google may use cookies to show ads based on your visits to the Service and to other sites. If you do not want personalized ads, you can turn them off in Google's Ads Settings (google.com/settings/ads). For details, see Google's "Advertising – Privacy & Terms" ( policies.google.com/technologies/ads).
  • Google Analytics: to understand how the Service is used, analytics information is collected using cookies. The information collected is managed by Google and handled under Google's Privacy Policy (policies.google.com/privacy). If you do not want it collected, use the opt-out add-on provided by Google (tools.google.com/dlpage/gaoptout) or disable cookies in your browser.

Apart from these, we do not provide information to third parties without your consent, except where required by law.

4. How long we keep it

  • Information linked to your account is kept until you delete your account. When you delete it, your nickname, avatar and play records are erased.
  • Records made while you are not logged in are kept linked to the anonymous identifier. If you clear your browser's cookies, they can no longer be traced back to you.
  • Connection logs are deleted after the period set by each infrastructure provider.

5. What you can do

  • You can change your nickname and avatar at any time on the account page. However, you can upload a new image up to 3 times a day.
  • You can delete your account on the account page.
  • To ask for disclosure or deletion of your information, please contact us at the address below.

6. If you live in the EEA, the United Kingdom or Switzerland

If you use the Service from the European Economic Area (EEA), the United Kingdom or Switzerland, the following applies in addition to the above.

  • Controller: the Operator is the controller responsible for your information. Contact details are given below.
  • Legal bases: providing the game, login and the paid plans is necessary to perform our contract with you (the Terms of Use). Dealing with abuse, investigating faults and improving the Service are based on the Operator's legitimate interests. Cookies for analytics and advertising are based on your consent.
  • Cookie consent: if you use the Service from these regions, we do not use cookies for analytics and advertising until you have given your consent. You can use the Service without consenting. Once we start showing a message asking for consent, you can withdraw your consent at any time from the settings in that message.
  • Your rights: you can ask for access to your information, for it to be corrected or erased, for its handling to be restricted, and to receive it in a form you can take to another service, and you can object to its handling. Please contact us at the address below. You can also lodge a complaint with the supervisory authority in your country.
  • Transfers abroad: your information is handled in Japan and in the countries where the servers of the services listed in "3. Sharing with outside services" are located (such as the United States). These transfers rely on safeguards set by each service, such as standard contractual clauses.

7. Changes

This policy may be changed when necessary. The changed policy applies from the time it is posted on the Service.
