プライバシーポリシー

Terms of Use (English)

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

These terms set out the conditions for using Probably Yes (「たぶんはい」, the "Service"), provided by 株式会社なりたんこーぽれーしょん (the "Operator"). By using the Service, you agree to these terms.

1. The Service

The Service is a game in which you guess one word a day by asking questions that can be answered yes or no. The answers to your questions are judged by AI and may sometimes be wrong.

2. Accounts

  • You log in with a Google account. You can also play without logging in.
  • Your nickname and avatar are shown to other users (for example, on the leaderboard).
  • You can delete your account at any time. When you do, your nickname, avatar and play records are erased and cannot be restored.

3. Prohibited conduct

  • Using images or names that are sexual, violent, discriminatory or hurtful to others.
  • Impersonating another person, or using images that infringe the rights of others (such as copyright or portrait rights).
  • Using multiple accounts or programs to manipulate the leaderboard or game results.
  • Placing an excessive load on the Service.

4. Images you upload

  • Only images that pass an automated check are shown. You can upload an image up to 3 times a day.
  • The Operator may remove or change, without notice, any image or name that violates these terms or that it judges to be inappropriate. An image that receives a certain number of reports is hidden until the Operator has reviewed it.
  • You keep the rights to the images you upload. The Operator uses them to the extent needed to display them in the Service.

5. Paid plans: Encore and Unlimited Encore

  • The paid plans are Encore (「おかわり」) and Unlimited Encore (「無限おかわり」). If you subscribe from a page in English, Spanish, Chinese or Korean, you are charged in US dollars: Encore is $3 a month and Unlimited Encore is $8 a month. If you subscribe from a page in Japanese, you are charged in Japanese yen: ¥300 a month and ¥800 a month (tax included). You are charged when you subscribe and then automatically on your renewal date each month. Payments are processed by Stripe; the Operator does not hold your card number.
  • The paid plans let you play words other than the daily puzzle, solo or in a two-player match. Encore allows up to 20 plays a day, counting solo plays and matches together. Unlimited Encore has no limit on plays.
  • If you are subscribed to Encore, you can switch to Unlimited Encore from that moment by paying the difference of $5 (or ¥500, tax included, for a subscription in yen). From your next renewal date, the price is that of Unlimited Encore.
  • You can ask to switch from Unlimited Encore back to Encore on the account page. The switch takes effect on your next renewal date; until then you stay on Unlimited Encore.
  • You can cancel at any time under "Manage billing" on the account page. After you cancel, you can keep playing until the end of the period you have paid for. Amounts already paid (including the difference paid for switching) are not refunded.
  • If the Service is used by automated means such as programs, or used to an extreme degree, the Operator may ask for verification, or limit or suspend use.
  • The Operator may change the prices or the content of the plans. Any change will be announced on the Service in advance.
  • If you delete your account, your paid plan also ends.

6. Disclaimer

  • The Service is provided as is. The Operator does not guarantee that its content is accurate, that it will be available without interruption, or that it is fit for a particular purpose.
  • The Operator is not liable for damage arising from the use of, or inability to use, the Service, except where the Operator acted intentionally or with gross negligence.
  • The Operator may change, suspend or end the Service at any time.

7. Changes to these terms

The Operator may change these terms when necessary. The changed terms apply from the time they are posted on the Service.

8. Governing law

These terms are interpreted in accordance with the laws of Japan.
