SERVICE INFORMATION

Service Name:
HAKONE AI

Service Description:
A private AI and digital-wellbeing service designed for adults.

Country of Origin:
Japan

Intended Users:
Adults aged 18 and over.

HAKONE AI is built around adult self-determination and human control.

It provides digital tools, structured experiences, individually configured support, and AI-assisted functions designed to help users pause, reflect, and make their own decisions about their relationship with digital technology.

HAKONE AI is not a child-monitoring service, parental-control service, or surveillance tool.

It is not a medical, therapeutic, diagnostic, or emergency-response service.

SELLING PRICE

Prices for HAKONE AI services are displayed on the applicable service, application, purchase, or checkout page before the user completes the transaction.

The price shown for the selected service at the time of purchase is the applicable selling price.

ADDITIONAL FEES

No additional HAKONE service fees will be charged unless they are clearly disclosed before purchase.

Users are responsible for costs associated with their own:

internet connection,

device and equipment,

telecommunications,

currency conversion,

and any fees independently charged by their payment provider or financial institution.

PAYMENT METHOD

PayPal

Available payment details are displayed before the transaction is completed.

PAYMENT TIMING

For one-time payments, payment is processed when the applicable purchase or service application is completed.

For subscription services, the initial payment is processed when the subscription begins, and subsequent payments are processed according to the recurring billing schedule presented before purchase and through PayPal.

Users should review the applicable billing cycle and renewal conditions before completing a purchase.

SERVICE DELIVERY

Access to digital services, onboarding materials, or other applicable HAKONE functions begins following successful payment and, where applicable, completion or approval of the required application process.

Certain HAKONE services are individually configured for the user.

Where individual setup is required, service availability may depend on the information provided, technical preparation, configuration requirements, and the specific service selected.

Any service-specific delivery or setup conditions will be presented as part of the applicable application or purchase information.

PRIVATE ASSESSMENT AND INDIVIDUAL CONFIGURATION

Certain HAKONE services may begin with a Private Assessment.

The Private Assessment is used to understand the adult applicant’s intended use, digital-wellbeing goals, relevant routines, preferences, and information necessary for individual configuration of the service.

It is not a medical examination, psychological diagnosis, or emergency assessment.

Submitting a Private Assessment does not itself guarantee acceptance into, or immediate activation of, every HAKONE service.

Where approval or individual configuration is required, this will be explained before the applicable service begins.

SUBSCRIPTIONS AND CANCELLATION

Where a HAKONE service is provided as a subscription, the applicable billing cycle and renewal conditions will be displayed before purchase.

Users may cancel future subscription renewals using the cancellation method provided for the applicable plan, including through PayPal where available.

Unless otherwise stated in the terms presented at purchase, cancellation of a subscription prevents future renewal and takes effect at the end of the current paid billing period.

Cancellation does not prevent the user from exercising any rights available under applicable law.

For assistance with cancellation, please contact:

contact@personal-shaman.com

REFUNDS

Refund eligibility and any applicable refund conditions are presented with the relevant service or plan before purchase.

Where a specific refund or money-back policy is offered, the applicable period, conditions, and procedure will be stated with that offer.

For services involving individual configuration, setup, assessments, or digital content, refund eligibility may depend on the stage at which the service has been provided and the conditions presented before purchase.

Nothing in this policy limits any refund or consumer right that must be provided under applicable law.

For questions regarding refund eligibility, please contact:

contact@personal-shaman.com

RETURNS

HAKONE AI is a digital service.

No physical goods are supplied as part of the HAKONE AI service unless explicitly stated in a specific offer.

Accordingly, there are generally no physical products to return.

OPERATING ENVIRONMENT

Users are responsible for preparing the equipment and services necessary to access HAKONE AI, including:

a compatible device,

internet access,

a supported web browser,

and email access.

Certain functions may depend on device capabilities, browser settings, network conditions, geographic region, or the availability of third-party infrastructure.

Users should review any specific technical requirements presented for the service they select.

IMPORTANT SERVICE BOUNDARIES

HAKONE AI is designed exclusively for adults aged 18 and over.

HAKONE AI is not a surveillance tool.

HAKONE AI is not a medical, therapeutic, diagnostic, or emergency-response service.

The final decision remains with the user.

THIRD-PARTY SERVICES

HAKONE AI may use third-party services where necessary for payment processing, cloud infrastructure, communications, artificial intelligence, website operation, or other technical functions.

Third-party providers may operate under their own terms and privacy policies.

Information concerning the handling of personal data and the use of relevant third-party infrastructure is provided in our Privacy Policy and related service documents.

Tokkyu Hosokawa

Digital Public Health Auditor / Algorithmic Ethics Designer. Drawing on expertise across the disciplines of law, systems engineering, and biology, he has conducted research in digital science for a decade—since 2014—based on empirical data from 1,500 families. He leads the design of "HAKONE," a practical infrastructure that enables human agency to remain central while fostering coexistence with the commercial algorithms of major platforms—advancing them rather than seeking their exclusion or legal restriction. He also spearheads proposals to fill the "policy gap" regarding digital autonomy for adults.

This system is not a service that provides medical care, treatment, diagnosis, or emergency response. HAKONE AI does not diagnose, treat, prevent, or predict any diseases, disorders, or mental health conditions.

Our goal is to help users establish calm screen-time habits and maintain control and autonomy over their digital devices within the commercial algorithmic environments of major platforms.

HAKONE AI is designed based on principles of digital public health, privacy protection, responsible AI, data minimization, transparency, and "human oversight." These principles align with international discussions and guidelines regarding adult self-determination, AI governance, and privacy protection.

This system is designed and operated for use by adults aged 18 and older who possess the right to self-determination.

We collect only the minimum information necessary to tailor the service to the individual user's context, and our policy is to clearly explain the handling of personal information in our Privacy Policy. Details regarding data handling, storage, the use of third-party AI, and security practices are outlined in the Privacy Policy and Terms of Service.

HAKONE AI is a service independently developed and operated by Synapse Cascade Gomei Kaisha. While we may utilize third-party AI infrastructure or APIs to provide specific features, we do not have an official affiliation, endorsement, or partnership with any AI provider unless explicitly stated.  © 2026 HAKONE AI.
