By downloading or using the Service, Users are deemed to have agreed to these Terms.

The Privacy Policy separately established by the Developer and any other individual rules shall constitute part of these Terms. In the event of any conflict between these Terms and individual rules, the individual rules shall prevail.

Users must not engage in any of the following acts when using the Service.

Acts that violate laws or public order and morals
Acts that are criminal or that lead to criminal acts

Unauthorized access or any attempts thereof
Copying, modifying, decompiling, disassembling, or reverse-engineering the app or any part thereof
Impersonating other users or third parties
Providing benefits to antisocial forces or equivalent conduct
Any other conduct that the Developer reasonably deems inappropriate

Article 3 (Intellectual Property)

All copyrights, trademarks, patents, design rights, and other intellectual property rights relating to the Service belong to the Developer or rightful rights holders.

Users may not reproduce, transfer, lend, translate, adapt, publicly transmit, display, distribute, reprint, modify, or otherwise use all or part of the Service beyond the scope expressly permitted by these Terms.

Copyrights to data created and stored by users in the Service ("User Data") belong to the users.

Opinions, suggestions, and feedback provided by users to the Developer may be freely used by the Developer without compensation.

Article 4 (Data Handling)

The core processing of this app (note creation, storage, search, etc.) is designed to operate entirely on the user's device. Note data and other data entered or created by users in the app ("User Data") are not transmitted to or stored on servers managed by the Developer.

User Data backup is performed to iCloud associated with the user's Apple Account, which the Developer cannot access.

Management of User Data, enabling or disabling backup, restoration, and deletion are the user's responsibility. The Developer assumes no liability for any loss, damage, leakage, or other harm to User Data.

Users who handle personal information of others through this app shall comply with applicable personal information protection laws and regulations on their own responsibility.

Article 5 (Paid Features and Billing)

Some features of the Service are provided as paid features through Apple's App Store billing system ("In-App Purchase").

Pricing, payment methods, terms of provision, and refund handling are subject to the terms set by Apple Inc. and the content displayed on the App Store.

Users wishing to request a refund for In-App Purchases must do so directly with Apple Inc. in accordance with Apple's procedures. The Developer assumes no responsibility for refunds or other obligations in this regard.

Article 6 (Changes, Interruptions, and Termination of Service)

The Developer may change, add, or delete all or part of the Service without prior notice to users.

The Developer may suspend all or part of the Service without notice for system maintenance, inspections, updates, force majeure events (earthquakes, lightning, fire, power outages, natural disasters, etc.), communication line failures, or similar reasons.

When terminating all or part of the Service, the Developer will endeavor to notify users in advance by reasonable means where possible.

The Developer assumes no liability for any damages incurred by users or third parties due to changes, interruptions, or termination of the Service under this article.

Article 7 (Restrictions on Use)

The Developer may restrict all or part of a user's access to the Service without prior notice if the user violates any provision of these Terms, is determined to be associated with antisocial forces, or if the Developer otherwise reasonably determines that use of the Service is inappropriate.

The Developer assumes no liability for any damages incurred by users as a result of actions taken under this article.

Article 8 (Handling of Personal Information)

Personal information collected from users in connection with use of the Service shall be handled in accordance with the Developer's separately established Privacy Policy (https://infinitenote.juntaki.com/privacy-policy), and users agree to such handling.

Article 9 (Disclaimer and Limitation of Liability)

The Developer does not guarantee the accuracy of the Service's output or functionality. Users shall verify results at their own responsibility.

The Developer does not warrant that the Service is free from defects in fact or law (including defects, errors, bugs, or infringement of rights related to safety, reliability, accuracy, completeness, effectiveness, fitness for a particular purpose, or security).

The Developer assumes no liability for any damages incurred by users in connection with the Service. However, this limitation does not apply where the agreement between the Developer and user qualifies as a consumer contract under the Consumer Contract Act.

Even in the case of the preceding proviso, the Developer shall not be liable for: (a) special damages, incidental damages, indirect damages, lost profits, loss or corruption of data, or damages based on claims by third parties arising from the Developer's minor negligence; and (b) the total liability of the Developer shall not exceed the total amount actually received from the user in the preceding 12 months (or JPY 1,000 in the case of free use).

The Developer does not warrant compatibility between the Service and the user's device, operating system, other applications, or third-party services.

Article 10 (Special Provisions for Apple Device Apps)

When this app operates on iOS or other platforms provided by Apple Inc. ("Apple"), the following conditions apply.

These Terms are entered into between the User and the Developer. Apple is not a party to these Terms. The Developer alone is responsible for the app and its content.
Apple and its subsidiaries are third-party beneficiaries of these Terms, and Apple has the right to enforce these Terms against the User.
If the app fails to conform to any applicable warranty, the User may notify Apple, and Apple may refund the purchase price. Apple has no other warranty obligation whatsoever.
The User represents and warrants that they are not located in a country subject to U.S. government embargo and are not listed on any U.S. government prohibited or restricted party list.

Article 11 (Use by Minors)

Minors must obtain the consent of a parent or other legal guardian before using the Service. If a minor uses the Service by falsely claiming to have such consent, or employs any other fraudulent means to appear to have full legal capacity, all legal acts related to these Terms may not be rescinded.

Article 12 (Severability, Non-Assignment, and Non-Waiver)

If any provision of these Terms is found invalid or unenforceable under applicable law, the remaining provisions shall remain in full force and effect.

Users may not assign, transfer, pledge, or otherwise dispose of their status under these Terms or any rights or obligations hereunder to any third party without the prior written consent of the Developer. The Developer may assign its status and rights and obligations under these Terms to a successor in the event of a business transfer, and users hereby consent to such assignment in advance.

Even if the Developer fails to exercise or delays the exercise of any right under these Terms, this shall not be deemed a waiver of such right.

Article 13 (Changes to Terms)

The Developer may change these Terms without obtaining individual user consent in either of the following cases, in accordance with Article 548-4 of the Civil Code: (1) when the change is in the general interest of users; or (2) when the change is not contrary to the purpose of the agreement and is reasonable in light of the necessity of the change, the reasonableness of the changed content, and other circumstances.

When changing these Terms, the Developer will notify users of the change, the changed content, and the effective date by posting within the app or on its website at least one month before the effective date.

If a user uses the Service after the effective date of the changed Terms, that user is deemed to have consented to the changed Terms.

Article 14 (Governing Law and Jurisdiction)

These Terms shall be governed by the laws of Japan.

In the event of any dispute between users and the Developer arising out of or in connection with these Terms or the Service, the Tokyo District Court shall have exclusive jurisdiction as the court of first instance.
