1. Acceptance of Terms

By accessing or using Aiko, including the website located at aiko4u.com and any related applications, portals, interfaces, dashboards, devices, APIs, features, tools, documentation, support channels, and services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms").

If you do not agree to these Terms, you must not access or use the Service.

These Terms apply together with the Privacy Policy, Acceptable Use Policy, Subscription & Purchase Terms, Commercial Disclosure under Japanese Law, order forms, facility agreements, enterprise agreements, pilot agreements, consent forms, onboarding materials, and any other terms presented in connection with the Service.

If you access or use the Service on behalf of a facility, operator, company, organization, family member, older adult, guardian, legal representative, or other person, you represent that you have the authority to do so and to bind that party where applicable.

2. Service Provider

Legal Entity Name: Mitrofanova Mariia
Registered Address: To be provided upon request.

If the Service is provided through a different operating entity, reseller, Merchant of Record, payment provider, facility partner, or enterprise contract, the applicable entity and terms may be identified at checkout, in an order form, or in a written agreement.

3. Nature of Service

Aiko is a supervised, voice-first artificial intelligence (AI) companion and engagement service designed for older adults in adult day-service settings in Japan, including 通所介護 and 地域密着型通所介護 offices.

The Service supports communication, engagement, family connection, and facility-supervised interaction. It is not a medical device, healthcare provider, nursing-care provider, therapy provider, emergency-response service, monitoring service, diagnosis system, treatment system, or substitute for facility staff, family judgment, professional care, or emergency services.

The Service may include:

  • older-adult voice interface;
  • tablet, speaker, kiosk, or facility-device interface;
  • family portal, including mobile web or progressive web application features;
  • facility console;
  • facility roster and session controls;
  • profile onboarding;
  • relationship and authorization management;
  • family content contribution;
  • conversation starters;
  • AI-assisted conversation features;
  • speech-to-text and text-to-speech processing;
  • optional familiar-voice personalization using authorized voice samples;
  • synthetic voice output with disclosure controls;
  • session summaries;
  • staff summaries;
  • family summaries;
  • usage and engagement reporting;
  • non-clinical sentiment, tone, or engagement indicators;
  • support workflows;
  • incident reporting workflows;
  • consent and authorization records;
  • account, subscription, and billing controls;
  • export, erasure, deletion, and account-management controls;
  • administrative tools;
  • other related features.

Aiko is intended for supervised use in facilities unless a written agreement or product documentation expressly states otherwise.

4. Pilot, Beta, Limited, or Pre-Release Use

The Service may be provided as a pilot, beta, proof of concept, test deployment, invitation-only service, unpaid service, discounted service, or limited-access service.

During any pilot, beta, limited, or pre-release period:

  • features may be incomplete, experimental, unavailable, changed, suspended, or discontinued;
  • the Service may contain errors, bugs, latency, interruptions, mistranscriptions, incorrect summaries, degraded voice quality, or inaccurate AI outputs;
  • access may be limited by facility, user group, geography, device, account status, whitelist status, payment status, consent status, operational readiness, or technical availability;
  • no production-grade availability, continuity, support, performance, service-level agreement, data-retention commitment, or feature commitment applies unless stated in a signed written agreement;
  • use is at the user’s, family’s, facility’s, and operator’s own responsibility to the fullest extent permitted by law.

The Service provider may approve, deny, suspend, revoke, restrict, or end pilot or beta access for legal, operational, security, commercial, compliance, safety, capacity, or policy reasons.

5. Eligibility

You must be at least 18 years old, or the legal age required in your jurisdiction, to create an account, submit data, provide consent, pay for the Service, manage an older-adult profile, operate a facility account, or use administrative features.

Older adults may use the Service only through authorized, supervised, and consented access flows appropriate to the deployment model.

By using the Service, you represent that you meet the applicable age, authority, capacity, consent, and authorization requirements.

6. Accounts and Access

Where account functionality is available:

  • you are responsible for maintaining account security;
  • you must provide accurate, current, and lawful information;
  • you are responsible for all activity under your account;
  • you must not share, sell, rent, transfer, or assign your account without written permission;
  • you must promptly notify the Service provider of unauthorized access, suspected compromise, incorrect authorization, or misuse.

Facilities and operators are responsible for assigning access only to authorized staff and for removing access when a staff member, contractor, family member, or representative no longer has a valid role.

The Service provider is not responsible for losses caused by unauthorized access resulting from user, family, facility, operator, device, network, credential, or access-control failures outside the Service provider’s reasonable control.

7. Facility, Operator, and Staff Responsibilities

Facilities, operators, staff, contractors, and other professional users are responsible for:

  • deciding whether the Service is suitable for their operational setting;
  • ensuring adequate supervision during older-adult sessions;
  • obtaining, recording, maintaining, and verifying all consents, permissions, notices, and authorizations required for their use case;
  • confirming the identity, relationship, and authority of family members, guardians, legal representatives, and other approved users;
  • ensuring that older adults are not misled about the AI nature of the Service;
  • maintaining clear disclosure that synthetic or familiar-voice output is AI-generated where applicable;
  • complying with applicable laws, regulations, care obligations, facility policies, professional standards, employment obligations, procurement rules, privacy obligations, and safety obligations;
  • training staff and supervising use of the Service;
  • reviewing outputs before relying on them operationally;
  • monitoring for distress, confusion, complaints, inappropriate use, consent withdrawal, or escalation events;
  • handling emergencies, care decisions, family communications, safeguarding, incident response, and legal duties outside the Service;
  • maintaining appropriate devices, networks, physical environments, and access controls;
  • ensuring that the Service is not used as a replacement for human care, staffing, monitoring, professional judgment, or required supervision.

The Service provider does not operate the facility, provide care services, supervise older adults, verify family relationships in the physical world, determine legal capacity, or assume facility duties unless expressly agreed in a signed written agreement.

8. Family, Guardian, and Representative Responsibilities

Family members, guardians, legal representatives, and other personal users are responsible for:

  • providing accurate information;
  • submitting only content, voice samples, photos, messages, memories, prompts, and other materials they are authorized to provide;
  • obtaining all required permissions from voice sample providers, older adults, family members, rights holders, guardians, or representatives;
  • keeping account credentials secure;
  • reviewing summaries and AI outputs critically;
  • not using the Service to deceive, manipulate, pressure, exploit, or impersonate any person;
  • notifying the facility or Service provider if authorization, consent, relationship status, or contact information changes;
  • independently verifying important information before acting on it.

A family member’s authorization to use or manage a profile does not by itself establish legal guardianship, medical authority, financial authority, or care authority.

9. Consent, Voice Samples, and Familiar-Voice Personalization

Familiar-voice personalization is optional and may be unavailable, limited, or disabled depending on product configuration, vendor availability, consent status, facility settings, legal requirements, and operational readiness.

Where familiar-voice personalization is enabled, the Service may request a voice sample of the length shown during onboarding, which may be approximately 5–10 minutes depending on provider requirements and product configuration.

You must not submit, record, upload, clone, synthesize, reproduce, or use any person’s voice unless you have all required rights, permissions, consents, and authority to do so.

You must not use familiar-voice personalization or synthetic voice output:

  • without clear authorization from the relevant voice provider or authorized representative;
  • to impersonate a person without disclosure;
  • to mislead an older adult, family member, staff member, authority, or third party;
  • to create fraudulent, defamatory, abusive, exploitative, manipulative, sexual, discriminatory, political, commercial, or unlawful content;
  • after consent has been withdrawn or authorization has ended;
  • outside the scope disclosed during onboarding or agreed in writing.

The Service may require consent records, staff attestations, versioned disclosure scripts, audit logs, revocation records, and other controls before voice capture, voice processing, or familiar-voice output is enabled.

10. User Content

"User Content" means any content, voice samples, audio, text, photos, memories, notes, messages, prompts, family content, profile information, relationship information, facility information, metadata, consent records, session records, summaries, documents, uploads, feedback, and other materials submitted to, created through, or processed by the Service.

You retain ownership of your User Content, subject to these Terms.

You grant the Service provider a limited, non-exclusive, worldwide license to host, store, copy, process, transmit, format, extract, transcribe, summarize, analyze, classify, embed, retrieve, generate outputs from, display, disclose to authorized users, secure, audit, export, erase, delete, and otherwise use User Content as necessary to provide, maintain, secure, troubleshoot, improve, enforce, and support the Service.

You represent and warrant that:

  • you have the necessary rights, permissions, and authority to submit and process User Content;
  • User Content does not violate applicable law, third-party rights, privacy rights, publicity rights, intellectual-property rights, confidentiality duties, facility policies, or contractual obligations;
  • User Content does not contain malware, harmful code, illegal material, or prohibited content;
  • User Content is accurate where accuracy is necessary for safe, lawful, or authorized use;
  • you will not submit content that you are not authorized to process through the Service.

11. AI Outputs

The Service may generate conversations, responses, summaries, staff notes, family summaries, prompts, non-clinical sentiment or tone indicators, engagement indicators, alerts, suggested next steps, reports, metadata, citations, and other AI-assisted outputs ("AI Outputs").

AI Outputs may be inaccurate, incomplete, outdated, biased, mistranscribed, mistranslated, inappropriate, unavailable, or affected by missing data, incorrect data, user input quality, audio quality, device conditions, facility environment, accent, dialect, hearing or speech differences, model limitations, retrieval limits, vendor availability, network issues, latency, or system degradation.

AI Outputs are provided for informational, organizational, engagement, and communication-support purposes only. They are not factual guarantees, professional conclusions, diagnoses, treatment recommendations, clinical assessments, medical advice, mental-health advice, legal advice, financial advice, care instructions, safety determinations, emergency alerts, or final determinations.

You are responsible for reviewing AI Outputs, verifying important information independently, and deciding whether any output is appropriate for use.

12. No Medical, Clinical, Care, or Emergency Service

The Service does not provide medical care, nursing care, long-term care, caregiving services, mental-health services, therapy, diagnosis, treatment, prevention, clinical monitoring, risk scoring, emergency response, or professional advice.

The Service must not be used:

  • to diagnose, treat, cure, prevent, monitor, or manage any disease, condition, impairment, injury, mental-health issue, or safety risk;
  • as a substitute for care staff, family supervision, clinical judgment, professional advice, emergency services, or facility procedures;
  • as the sole basis for decisions about medication, treatment, care level, restraints, hospitalization, discharge, safeguarding, emergency response, legal capacity, finance, insurance, employment, or other high-impact matters.

If there is a medical emergency, mental-health crisis, risk of self-harm, risk of harm to others, safeguarding concern, abuse concern, neglect concern, or other urgent safety issue, users must contact local emergency services, facility staff, qualified professionals, or appropriate authorities immediately.

The Service provider is not responsible for emergency detection, emergency escalation, care outcomes, clinical outcomes, facility staffing, family response, or actions taken or not taken by users, families, facilities, staff, operators, or third parties.

13. Third-Party Services and Providers

The Service may rely on third-party providers for hosting, storage, identity, authentication, speech-to-text, text-to-speech, familiar-voice synthesis, AI models, email delivery, payment processing, analytics, observability, error monitoring, support, security, and other functions.

Third-party providers may process data according to their own terms, privacy policies, service levels, restrictions, and technical limitations.

The Service provider is not responsible for third-party provider downtime, model behavior, pricing changes, policy changes, security incidents, unavailability, discontinuation, processing errors, or feature changes except to the extent required by law or expressly agreed in a signed written agreement.

14. Payments, Subscriptions, and Purchases

Paid services, subscriptions, usage-based services, pilot fees, facility subscriptions, enterprise licenses, family subscriptions, onboarding fees, professional services, or other paid features may be subject to the Subscription & Purchase Terms and any checkout or order-form terms.

Prices, billing cycles, renewal terms, cancellation methods, refund terms, taxes, service scope, limits, and payment timing will be disclosed at checkout, in the application, in an order form, or in a written agreement where required.

If the Service is provided free of charge, as a pilot, or during an unpaid access period, the Service provider may later introduce paid features, change access conditions, limit usage, or discontinue free access.

15. Intellectual Property

The Service, website, software, interfaces, designs, workflows, prompts, systems, models, documentation, logos, trademarks, content, and related materials are owned by the Service provider or its licensors and are protected by applicable intellectual-property laws.

Except as expressly permitted, you must not copy, modify, distribute, sell, lease, sublicense, reverse-engineer, decompile, disassemble, scrape, extract, create derivative works from, or commercially exploit any part of the Service.

No rights are granted except those expressly stated in these Terms.

16. Feedback

If you provide feedback, suggestions, bug reports, ideas, feature requests, or other comments, you grant the Service provider a perpetual, worldwide, royalty-free, irrevocable, sublicensable license to use them without restriction or compensation, unless prohibited by law or separately agreed in writing.

17. Acceptable Use

You must comply with the Acceptable Use Policy.

You must not use the Service for unlawful, deceptive, unsafe, abusive, infringing, exploitative, unauthorized, or high-risk purposes, including unauthorized voice cloning, undisclosed impersonation, professional advice, emergency monitoring, or decisions affecting legal rights.

18. Service Changes, Suspension, and Termination

The Service provider may modify, suspend, restrict, discontinue, or terminate any part of the Service at any time for legal, operational, security, safety, commercial, compliance, vendor, capacity, policy, or product reasons.

The Service provider may suspend or terminate access if:

  • you breach these Terms or related policies;
  • required consent or authorization is missing, withdrawn, disputed, or invalid;
  • continued access creates legal, safety, security, operational, reputational, vendor, or compliance risk;
  • payment fails or required billing information is invalid;
  • access is no longer available under a pilot, beta, facility, enterprise, or family arrangement;
  • required law, regulation, authority request, facility request, or third-party provider restriction requires suspension or termination.

Termination may result in loss of access to the Service, accounts, profiles, summaries, reports, and related data, subject to the Privacy Policy, applicable law, and written agreements.

19. Disclaimers

To the fullest extent permitted by law, the Service is provided "as is" and "as available," without warranties of any kind, whether express, implied, statutory, or otherwise.

The Service provider disclaims all warranties, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, reliability, availability, uninterrupted operation, error-free operation, security, suitability for care settings, suitability for any user, compatibility, voice quality, transcription accuracy, AI-output accuracy, or achievement of any engagement, loneliness, satisfaction, operational, clinical, commercial, or financial result.

The Service provider does not guarantee that:

  • the Service will be available, uninterrupted, secure, timely, or error-free;
  • AI Outputs will be accurate, complete, safe, suitable, or useful;
  • familiar-voice personalization will work for all voices, languages, speakers, accents, devices, or environments;

To the fullest extent permitted by law, the aggregate liability of the Service provider arising out of or related to the Service will not exceed the greater of:

  • the amount paid by you to the Service provider for the specific Service giving rise to the claim during the three months before the event giving rise to liability; or
  • JPY 10,000 if you used the Service free of charge, during a pilot, during a beta, or without direct payment to the Service provider.

Nothing in these Terms excludes or limits liability where exclusion or limitation is prohibited by applicable law.

21. Indemnification

To the fullest extent permitted by law, you agree to defend, indemnify, and hold harmless the Service provider and its owners, officers, employees, contractors, licensors, suppliers, service providers, and affiliates from and against any claims, damages, losses, liabilities, costs, and expenses, including reasonable legal fees, arising from or related to:

  • your access to or use of the Service;
  • User Content submitted by you or through your account;
  • unauthorized or unlawful voice sample collection, familiar-voice personalization, or synthetic voice use;
  • missing, invalid, withdrawn, or disputed consent or authorization;

This section applies only to the extent permitted by law and may not apply to consumers where prohibited by applicable consumer-protection rules.

22. Data Protection

Use of the Service is governed by the Privacy Policy.

You are responsible for ensuring that your submission and processing of personal information through the Service is lawful and authorized. Facilities, operators, and professional users are responsible for their own legal basis, notices, consent procedures, recordkeeping, and compliance obligations where they determine purposes or means of processing or otherwise have independent obligations.

23. Export, Deletion, and Retention

Data export, deletion, erasure, and retention features may be subject to technical limits, identity verification, account status, facility requirements, backup cycles, audit-log retention, legal holds, payment records, security records, dispute records, and applicable law.

Deletion may not immediately remove all data from backups, logs, audit records, legal records, vendor systems, or records retained for security, compliance, fraud prevention, accounting, dispute handling, or lawful operational purposes.

24. Confidentiality

Non-public Service information, including private documentation, pilot results, security information, pricing, roadmaps, dashboards, admin interfaces, credentials, implementation details, and other information marked or reasonably understood as confidential, must not be disclosed without written permission unless required by law.
