IMPORTANT: BIFROST Disclaimer & Safety Guidelines

This application (“BIFROST”) is a tool that uses advanced acoustic technology to support sound environments for focus and rest. To use it safely, please use the application only after agreeing to the following points. 1. Not a medical device and intended users BIFROST is not a medical device and is not intended to diagnose, treat, cure, or prevent any mental or physical disease. If you are currently receiving medical treatment, or if you have concerns about your mental or physical health, consult a qualified medical specialist before using this app. If you use an implanted medical device such as a cardiac pacemaker, follow instructions from your doctor and the device manufacturer. As a general rule, keep magnets and wireless equipment, including your device and earphones or headphones, at least 15 cm (6 in) from the implant; follow any stricter individual instruction. If you suspect interference, stop use immediately and consult your doctor or the manufacturer. BIFROST itself makes no claim of medical benefit. If you are pregnant and have any concerns, consult your doctor before use. If a minor uses this app for learning or completing tasks, they must have parental or guardian consent, and their usage time should be appropriately managed, including avoiding long continuous sessions. 2. Do not use while driving or during hazardous tasks The sound programs in this app, especially sessions in the slower modulation settings, may lead to drowsiness or reduced attention. Never use this app while driving a vehicle or operating dangerous machinery. 3. Warning for epilepsy and sound sensitivity All sound programs provided by this app, including binaural beats and special frequency modulation, may contain regular and continuous acoustic pulsing as well as left-right phase differences that create beat sensations. If you have a history of epilepsy or sensitivity to repetitive sound or light, avoid using these functions. 4. Stop use and legal responsibility BIFROST includes sound and visual guidance that may feel strong. If you experience discomfort, dizziness caused by screen movement or a motion-sickness-like sensation, severe headache, nausea, or any other unusual symptoms, stop the app immediately, remove your earphones, and rest. When playback starts, the sound may be louder than expected depending on your PC or device volume settings. This app cannot read or control your device's output volume. To protect your eardrums and hearing, always set both your device volume and the in-app volume to a low level before starting playback, then adjust gradually. Excessive volume or long continuous use may cause hearing loss, tinnitus, or related problems. These safety precautions do not ask you to waive legal liability. Liability relating to the App is governed by Section 7 of the Terms of Service, and liability or rights that cannot be limited under applicable law are not limited. Please use the App at an appropriate volume and for an appropriate duration according to your condition. 5. Privacy and audio data handling All audio data processed by the SYSTEM AUDIO OVERRIDE (external audio capture) feature is handled entirely in real time on your device using local DSP processing and is immediately discarded. No audio data is transmitted to, recorded by, or stored on our servers. 6. No warranty and disclaimer This app is provided AS IS, without warranty of any kind. No guarantee is made regarding fitness for any particular purpose, any particular outcome or experience, or complete operation across all devices and browsers. As a digital product, refunds based on incompatibility with your particular environment are generally unavailable, except where required by applicable conformity, refund, withdrawal, or other statutory rights, or by our expressly stated refund policy.

Terms of Service (Important Legal Provisions)

Effective date: August 29, 2026 · Version: 2026-08-29-v6

The company providing the App (the "Company") is クラウドナイン合同会社 (English rendering: Cloud Nine LLC (Godo Kaisha)).

The following are the legally binding terms governing your use of BIFROST (the "App"). Together with the safety notices above, you may use the App only if you agree to these terms.

7. Limitation of Liability
Nothing in this Section excludes or limits liability under mandatory law; liability for fraud, willful misconduct, or gross negligence; liability for death or personal injury caused by negligence; or any statutory consumer or privacy rights or remedies. For consumers, liability arising from ordinary negligence is limited, to the extent permitted by applicable law, to direct, ordinary, and reasonably foreseeable property loss; mandatory statutory rights and remedies always prevail. Only for users acting for business purposes or otherwise not acting as consumers, and to the maximum extent permitted by applicable law, the Company and its officers, employees, and agents shall not be liable for indirect, incidental, special, consequential, or punitive damages (including loss of data, profits, or goodwill) arising out of or relating to use of or inability to use the App. For those business or non-consumer users only, our total aggregate liability shall not exceed the greater of (a) the amount paid for the App in the twelve (12) months preceding the event giving rise to the claim, or (b) US$100.

8. Governing Law and Jurisdiction
These terms are governed by and construed in accordance with the laws of Japan, without regard to conflict-of-law principles. Except to the extent Section 9 validly applies, the Nara District Court has non-exclusive jurisdiction over disputes arising out of or relating to the App or these terms. Nothing in this Section deprives a consumer of the protection of mandatory laws in their place of residence or the right to bring proceedings in the courts of their place of residence or any other forum available under applicable law.

9. Binding Arbitration and Class Action Waiver (U.S. Residents)
This Section applies if you reside in the United States. Please read it carefully, as it affects your rights, including a waiver of jury trial and of participation in class actions. Any dispute arising out of or relating to the App or these terms will be finally resolved by binding, individual (one-on-one) arbitration administered by JAMS under its rules, pursuant to the Federal Arbitration Act (FAA), and not in court. You and the Company agree to bring claims only in your individual capacity, and not as a plaintiff or class member in any class, collective, or representative action. The arbitrator may not consolidate more than one person's claims. Arbitration will take place in the county where you reside or a location determined by JAMS. Either party may bring an eligible claim in small-claims court.
Opt-out: If you do not wish to be bound by this arbitration provision, you may opt out by sending written notice (email is acceptable) to info@cloud9llc.jp within 30 days of the date you first agree to these terms. Opting out will not affect any other part of these terms. Nothing in this Section prevents you from exercising any right or remedy that cannot be waived under applicable law.

10. Severability, Changes, and Entire Agreement
If any provision of these terms is held invalid or unenforceable, the remaining provisions will remain in full force and effect; provided, however, that if the class action waiver in Section 9 is held invalid or unenforceable as to a particular claim, the entire arbitration provision shall not apply to that claim. We may update these terms from time to time and will request your agreement again on startup for material changes. These terms constitute the entire agreement between you and the Company regarding your use of the App.

11. Eligibility; Minors and Parental Consent
The App may be used only by an individual who has reached the age of majority where they live, or by a minor aged 13 or older whose parent or legal guardian gives consent. By permitting such use, the parent or guardian agrees to these Terms (including Sections 7–10) on the minor's behalf and accepts responsibility for compliance. Children under 13 may not use the App.

12. Start of Digital Supply and Withdrawal Rights
When purchasing a paid plan, you expressly request that digital service supply begin on the start date shown in the applicable checkout (Stripe or Digistore24). You acknowledge, only to the extent permitted by applicable law, that immediate performance may affect a withdrawal or cancellation right. Mandatory rights concerning conformity, refunds, withdrawal, cancellation, or other remedies remain unaffected.

Governing language: Each language version of these terms is provided for convenience; in case of any discrepancy, the Japanese version prevails.
