Terms of Service

Last updated: 1 June 2025

This English version of the Terms of Service is for reference only. The Japanese version of the Terms of Service is the original. If there is any conflict or inconsistency between these two versions, the Japanese version shall take precedence. You acknowledge that Japanese shall be the language of reference for interpreting and constructing the terms.

1. Acceptance of These Terms

These Terms of Service (these “Terms”) form a legally binding agreement between n, Inc. (the “Company”, “we”, “our” or “us”) and the individual or entity that creates an account or otherwise uses the Fastnote service (the “Service”). By clicking “I Accept” or by accessing or using any part of the Service, you (the “User”, “you” or “your”) agree to be bound by (a) these Terms, (b) any policies or guidelines posted on the Service or our website, and (c) our Privacy Policy.

The Service is intended only for individuals who are at least eighteen (18) years old (or the age of legal majority in their jurisdiction, if higher). By using the Service, you represent and warrant that you meet this requirement.

2. Definitions

Capitalized terms used but not defined in context have the meanings set out below.

  • Account Information – any ID, password or other credential assigned to, or registered by, the User for the Service.
  • Content – (i) information that you input to or upload into the Service and (ii) any output generated by the Service in response to such input or upload.
  • Service Agreement – the agreement for use of the Service formed under section 3.

3. Formation of the Service Agreement

  1. An individual who wishes to use the Service must apply in the manner we designate. Upon our approval, the Service Agreement comes into effect.
  2. If you apply on behalf of a company, you represent and warrant that you have authority to bind that company; once approved, both you and the company are bound.
  3. We may refuse any application if we reasonably believe that
    • (a) the applicant may violate these Terms;
    • (b) information provided is false, incorrect or incomplete;
    • (c) the applicant is or is connected with an antisocial force; or
    • (d) approval would otherwise be inappropriate.
  4. You must provide and maintain true, accurate and current information.

4. Use of the Service and Fees

  1. Plans and limits – We may, at our discretion, make certain features or usage volumes available at no charge so that prospective users can evaluate the Service. All usage caps, paid-access tiers, billing cycles and current prices are displayed on the Plan page of the Service and may change from time to time.
  2. Recurring billing – Unless otherwise stated on the Plan page, paid access renews automatically at the end of each billing cycle until you cancel. You may cancel at any time through the account-management interface; cancellation takes effect at the end of the then-current cycle.
  3. Payment method – All fees are payable in advance using any payment method that we make available on the Plan page or in the account-management interface.
  4. No refunds – Except to the extent required by applicable law, fees actually received by the Company are non-refundable.

5. Account Security

You must keep your Account Information confidential and must not permit any third party to use it. If you become aware of unauthorized use, you must notify us immediately. Except where we are at fault, you are liable for all activity conducted under your Account Information.

6. Prohibited Conduct

7. Suspension and Termination

  1. We may suspend your access to all or part of the Service, or delete any of your Content, without notice, if we reasonably determine that you have violated or are likely to violate these Terms.
  2. If such suspension is not cured within any period we specify, or if we otherwise reasonably consider continued use inappropriate, we may terminate the Service Agreement immediately.
  3. Upon termination, all unpaid amounts become immediately due.

  3. Statistical use – We may process your Content in a de-identified form to create statistics and other aggregated data for the purpose of improving the Service.
  4. Except as stated in this section, you retain all rights, title and interest in and to your Content, and the Company claims no ownership.

  6. We may list your company name, trademark and logo as a customer for promotional purposes.

9. No Warranties

The Service and all output it generates are provided “as is” and “as available.” We disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness and uninterrupted availability. You are solely responsible for reviewing and verifying any output before using it.

10. Limitation of Liability

Except for liability that cannot be limited under applicable law, our total liability to you for all claims arising out of or relating to the Service will not exceed the total fees you paid to us for the Service in the three-month period preceding the event giving rise to the claim. We are not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue, data or goodwill.

11. Indemnification

You agree to indemnify and hold harmless the Company, its directors, officers, employees and agents from and against any and all claims, damages, losses, liabilities, costs and expenses (including reasonable attorneys’ fees) arising out of or relating to (a) your Content, (b) your breach of these Terms, or (c) your use of the Service or any output in violation of law or the rights of any third party.

12. Confidentiality

Each party must keep confidential any non-public information designated as confidential and obtained from the other party in connection with the Service, and must not use such information except as necessary to perform or receive the Service. This obligation survives for two years after termination.

13. Modifications

We may revise these Terms or the Service at any time. If we make material changes, we will post the revised Terms and indicate the “Last updated” date. Continued use of the Service after changes become effective constitutes acceptance of the revised Terms.

14. Governing Law and Dispute Resolution
