Soroban App Terms of Use

This is an English reference translation. Only the Japanese version is legally binding. If the two versions differ, the Japanese version prevails.

These Terms set out the conditions for using the smartphone and tablet app "Soroban" (the "App") provided by SIC Co., Ltd. ("we", "us" or "our"). Anyone who uses the App (a "User") shall use the App after agreeing to these Terms.

Article 1 (Application)

  1. These Terms apply to all relationships between us and Users concerning the use of the App.
  2. User information handled in the App is governed by the Soroban App Privacy Policy.
  3. For the App obtained from the App Store, the Licensed Application End User License Agreement set by Apple applies together with these Terms. For the App obtained from Google Play, the Google Play Terms of Service apply together with these Terms.
  4. Subscriptions by schools and organizations to "Soroban Portal" are governed by the Soroban Portal Terms of Use.

Article 2 (Use by Minors)

  1. A minor shall use the App with the consent of a parent or guardian.
  2. Signing in with a Google Account or Apple Account, purchasing the paid plan, and contacting us are to be done by a parent or guardian.

Article 3 (Accounts)

  1. Users can use the App without signing in. Users who sign in with a Google Account or Apple Account can carry their learning records over to other devices.
  2. School accounts (Sorobase IDs) are issued and managed by schools and organizations. A school account may be used only by the user to whom it is assigned, and may not be transferred, lent or shared with a third party.
  3. Users are responsible for managing the information they use to sign in.
  4. Users can delete their sign-in information for a Google Account or Apple Account with "Delete Account" in the App's "Settings".

Article 4 (Paid Plan)

  1. Some features of the App are available to Users who have purchased the paid plan or who are signed in with a school account. The features available for free are as shown in the App.
  2. The paid plan is an auto-renewing subscription purchased through in-app purchase on the App Store or Google Play. The price, the period and whether a free trial is offered are as shown on the purchase screen.
  3. Unless the User cancels, the paid plan renews automatically at the end of each period, and the fee is charged through the App Store or Google Play. If a free trial is offered, it changes to a paid period when the trial ends.
  4. The paid plan is to be canceled on the subscription management screen of the App Store or Google Play. Deleting the App from a device or deleting an account does not cancel the paid plan.
  5. Payment, renewal, cancellation and refunds are governed by the rules of the App Store or Google Play.

Article 5 (Worksheets and Other Creations)

  1. Users may print and distribute worksheets, certificates, flyers and other items created with the App ("Creations") at home, in schools and in classrooms.
  2. Users may not post the PDF files of Creations themselves on websites or elsewhere, or sell them.
  3. The App's exam worksheets are practice materials we created independently based on the guidelines published by each organization, and are not actual exam questions. The App is not affiliated with any of these organizations.
  4. Users are responsible for handling the content they enter in Creations (such as school names, recipients' names and photos).

Article 6 (Intellectual Property Rights)

Copyrights and other intellectual property rights in the App and in the videos, problems, audio, images, text and other content included in the App belong to us or to third parties who hold the rights. Except as permitted by these Terms, Users may not reproduce, modify, transmit to the public or distribute them.

When using the App, Users may not do any of the following.

  1. Acts that violate laws and regulations or are against public policy
  2. Acts that modify or analyze the App or our servers, or interfere with their operation

  2. If a User suffers damage due to our default or a tort committed by us, we will compensate for the damage. However, if the damage is caused by our negligence (excluding gross negligence), the damage we compensate is limited to ordinary damage actually incurred by the User, and the amount is limited to the higher of the fees the User paid for the paid plan in the 12 months up to the day on which the damage occurred, or 10,000 yen.
