Terms of Service

Last updated: 2026-06-23

These Terms of Service (the "Terms") set out the conditions for using the iOS application "Primaly" (the "App") provided by Zero-Friction Labs ("we", "us").

Article 1 (Scope)

These Terms apply to all relationships between us and users regarding the use of the App. By downloading or using the App, you are deemed to have agreed to these Terms.

Article 2 (Eligibility)

The App is intended for users aged 13 or older. Minors may use the App only with the consent of a parent or legal guardian. The App includes an AI assistant feature (Article 8), and you must meet any applicable age requirements.

Article 3 (Account)

Using the App requires signing in via Apple's "Sign in with Apple". You are responsible for managing your own account and credentials. You can delete your account at any time from "Settings › Privacy & Security › Delete Account" in the App; doing so erases your account on the authentication provider and your on-device data. The handling of your data is as set out in our "Privacy Policy".

Article 4 (License)

We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial purposes in accordance with these Terms. You may not copy, modify, redistribute, sell, rent, or sublicense the App or any part of it, and you must comply with the prohibited conduct in Article 6.

Article 5 (Fees)

The App is currently provided free of charge. If paid features or purchases (including subscriptions) are introduced in the future, purchases will be made through the Apple App Store, and their pricing, renewal, and cancellation terms will be presented at that time. Subscriptions may auto-renew at the end of each period unless cancelled, and can be cancelled or managed from "Settings › Apple Account › Subscriptions" on iOS. Purchases are also subject to Apple's terms.

Article 6 (Prohibited conduct)

When using the App, users must not engage in any of the following:

  1. Acts that violate laws, regulations, or public order and morals
  2. Acts that infringe the intellectual property, privacy, or other rights of us or any third party
  3. Decompiling, reverse engineering, or otherwise analyzing the App
  4. Improperly manipulating, or placing excessive load on, the App or related servers and networks
  5. Intentionally attempting to make the AI assistant generate illegal or harmful content, or violating the usage policies of the AI provider (Anthropic, PBC)
  6. Impersonating others or registering false information
  7. Any other conduct that we deem inappropriate

Article 7 (User content and intellectual property)

Copyrights, trademarks, and all other intellectual property rights in the App and this website belong to us or to their rightful owners. Meanwhile, the records you create within the App (journal entries, tasks, habits, mood records, and so on; "User Content") belong to you. User Content is, in principle, stored only on your device, and we acquire no license to store or use it. The only exception is that, if you consent to using the AI assistant, part of your User Content is sent to and processed by the AI provider to the extent necessary to generate responses (as set out in our "Privacy Policy" and "About AI").

Article 8 (AI assistant features)

The AI assistant "Prima" uses generative AI and operates only if you consent. Its output is provided "as is" as reference information, and we do not warrant its accuracy or completeness. Do not rely on the output for critical decisions regarding health, medical, legal, or financial matters; consult a professional where necessary. When using the AI feature, you must comply with the prohibited conduct in Article 6 and with the usage policies of the AI provider (Anthropic, PBC). The handling of, and disclaimers regarding, output are as set out in "About AI".

Article 9 (Changes, interruption, termination, and suspension of the service)

We may change, interrupt, or terminate all or part of the App without prior notice to users in the following cases:

  1. When performing maintenance, inspection, or updates
  2. When unavoidable circumstances arise, such as natural disasters, outages, or failures of third-party services (including the OS and AI APIs)
  3. When we otherwise deem it necessary

In addition, if a user violates these Terms, we may suspend that user's use of the App or terminate their account without prior notice. We are not liable for damages incurred by users as a result, beyond the scope set out in these Terms.

Article 10 (Disclaimer; no warranty)

The App is provided "as is". We do not warrant the completeness, accuracy, usefulness, or fitness for a particular purpose of the App. The App includes alarm and health-related information displays, but it is not a substitute for professional advice on medical, health, or safety matters; do not rely on it as your sole means for any critical purpose.

Article 11 (Limitation of liability)

We are not liable for damages incurred by users arising from the use of, or inability to use, the App, except in cases of our willful misconduct or gross negligence. Where the App constitutes a consumer contract under Japan's Consumer Contract Act, this Article does not exclude any liability that cannot be excluded by law. Even where we are liable, compensation is limited to ordinary damages actually incurred, and does not include special, consequential, or lost-profit damages (except in cases of our willful misconduct or gross negligence).

Article 12 (Apple App Store provisions)

These Terms are an agreement between you and us, not with Apple Inc. ("Apple"). The license to the App downloaded from the App Store is governed by Apple's "Licensed Application End User License Agreement" (the standard EULA). These Terms supplement the standard EULA, and the provisions of the standard EULA (including that Apple has no maintenance or support obligation and that Apple and its subsidiaries are third-party beneficiaries entitled to enforce the agreement against you) also apply to your use of the App. In the event of any conflict between these Terms and the standard EULA, the standard EULA prevails with respect to the license to the App.

Article 13 (Governing law and jurisdiction)

These Terms are governed by the laws of Japan. Any dispute arising in connection with the App shall be subject to the exclusive jurisdiction of the court having jurisdiction over our location (without prejudice to any jurisdiction available under the Consumer Contract Act or other applicable law).

Article 14 (Miscellaneous)

The Japanese version of these Terms is the authoritative text; in the event of any discrepancy between a translation and the Japanese version, the Japanese version prevails. If any part of these Terms is held invalid or unenforceable, the remaining provisions remain in full force and effect. These Terms constitute the agreement between us and users regarding the use of the App.

Article 15 (Changes to these Terms)

We may amend these Terms when we deem it necessary. Material changes will be announced in the App or on this website. If you continue to use the App after a change, you are deemed to have agreed to the amended Terms.
