Using AikoAI

Terms of Use

These terms govern your use of the AikoAI iOS application and related services.

Effective and last updated: 23 September 2026

1. Agreement

These Terms of Use are an agreement between you and Metro Labs, the operator of AikoAI. By downloading, accessing or using AikoAI, you agree to these terms and the Privacy Policy. If you do not agree, do not use the service.

Apple Standard EULA

AikoAI is distributed through Apple's App Store. Apple's Standard End User License Agreement applies to the licensed iOS application unless a valid custom licence agreement is provided through App Store Connect. These Terms of Use supplement that licence for AikoAI's account, subscription, voice and online services. If any provision conflicts with a mandatory Apple term or applicable law, the mandatory term or law prevails.

2. The AikoAI service

AikoAI is an AI-powered Japanese conversation companion. It provides realtime voice conversations, learning-oriented interaction and optional personalisation using information remembered from earlier conversations.

AikoAI is a practice and general-information tool. It does not guarantee language proficiency, examination results, factual accuracy or any particular outcome.

3. Eligibility and your account

  • You must be at least 13 years old and legally permitted to use the service where you live. If you are under 18, you must have permission from a parent or legal guardian.
  • Sign in with Apple is optional. You may use AikoAI as a guest without linking a permanent Apple identity to your AikoAI profile.
  • Guest use still creates an authenticated AikoAI identifier in our backend so the service can securely associate your profile, subscription status, usage and conversation data with your current AikoAI session.
  • You may later choose Sign in with Apple to save or recover access to a permanent AikoAI account. Guest accounts may have more limited recovery options if access to the anonymous account is lost.
  • You are responsible for activity carried out through your AikoAI account or guest session, except where caused by our failure to use reasonable care.
  • You must provide accurate information and must not impersonate another person.

Keep your device and Apple account secure. Tell us promptly at help.metrolabs@gmail.com if you believe your AikoAI account, guest session or associated Apple account has been compromised.

4. Subscriptions, minutes and billing

Aiko Monthly

AikoAI is offered through an auto-renewing App Store subscription called Aiko Monthly — 200 Minutes. The subscription provides up to 12,000 seconds (200 minutes) of eligible live voice conversation during each billing period.

  • Aiko Monthly is required for live voice conversations whether you use AikoAI as a guest or with Sign in with Apple.
  • Sign in with Apple is not required to purchase, restore or use an eligible Aiko Monthly subscription.
  • The Apple account used by the App Store for purchasing and billing is separate from whether you choose to link Sign in with Apple to your AikoAI account.
  • The price shown in AikoAI or the App Store is the price that applies to your purchase. Prices are localised by Apple and may change subject to Apple's rules and notice requirements.
  • Payment is charged to your Apple account after you confirm the purchase.
  • The subscription automatically renews unless you cancel it through Apple at least as required by Apple's subscription rules.
  • You can manage or cancel your subscription in iOS Settings or at Apple's subscription-management page.
  • Deleting your AikoAI account does not automatically cancel an Apple subscription.
  • Restore Purchases checks the current App Store account for an eligible existing subscription.
  • Unused included voice minutes do not represent cash value and are not transferable between separate customers. The active billing period, subscription ownership and server-recorded usage determine availability.

Refund requests and billing disputes for App Store purchases are generally handled by Apple under its applicable policies and consumer-law obligations. Nothing in these terms removes statutory rights that cannot legally be excluded.

5. Acceptable use

You must not use AikoAI to:

  • break the law, infringe another person's rights or facilitate harm;
  • harass, threaten, exploit or deceive people;
  • share content you do not have the right to provide;
  • attempt to bypass subscription, usage, security or authentication controls;
  • probe, disrupt, overload, reverse engineer or gain unauthorised access to the service, except where applicable law expressly permits it;
  • automate excessive requests, resell access or use AikoAI to create a competing service without written permission; or
  • use AI output as instructions for emergencies, criminal conduct or high-impact decisions about another person.

We may limit or suspend access where reasonably necessary to protect users, providers or the service, investigate misuse, comply with law or enforce these terms.

6. Artificial-intelligence limitations

AikoAI can make mistakes. Its speech, translations, explanations, memories and other responses may be inaccurate, incomplete, outdated, unsuitable or unexpected.
  • AikoAI is not human and you should not assume it understands context in the way a person would.
  • Verify important translations and information independently.
  • AikoAI is not medical, mental-health, legal, financial, immigration, emergency or other professional advice.
  • Do not rely on AikoAI to contact emergency services. If you or someone else may be in danger, contact the appropriate emergency service directly.
  • You remain responsible for decisions you make and content you provide or use.

7. Content and intellectual property

AikoAI, its interface, branding, software and service materials are owned by us or our licensors and are protected by intellectual-property law. Subject to these terms, you receive a personal, limited, non-exclusive, non-transferable and revocable right to use the service.

You retain rights you hold in content you provide. You give us the limited permission needed to process that content to operate, secure and support AikoAI as described in the Privacy Policy. AI output may not be unique, and other users may receive similar output. You are responsible for checking whether your intended use of output is lawful and appropriate.

8. Changes and availability

We may update, improve, restrict or discontinue parts of AikoAI. Realtime AI, network, Apple, Supabase, RevenueCat or other provider outages may temporarily affect access. We do not promise uninterrupted or error-free availability, but this does not limit obligations that cannot legally be excluded.

9. Responsibility and liability

Nothing in these terms excludes or limits liability where doing so would be unlawful, including liability for fraud, fraudulent misrepresentation, or death or personal injury caused by negligence. Nothing in these terms affects mandatory consumer rights.

To the fullest extent permitted by law, we are not responsible for losses that were not reasonably foreseeable when you agreed to these terms, losses caused by events outside our reasonable control, or business losses arising from consumer use of AikoAI. AikoAI is supplied for personal and non-commercial use.

10. Ending your use

You may stop using AikoAI at any time. Both guest users and users who have linked Sign in with Apple can initiate account deletion in the app as described on the account-deletion page. Remember to cancel any active Apple subscription separately if you do not want it to renew.

Deleting a guest account permanently removes access to that guest identity. If you have not linked the account to Sign in with Apple, there may be no way to recover that account after deletion or loss of access.

We may suspend or end access if you materially breach these terms, create security or legal risk, or if we discontinue the service. Where reasonable, we will provide notice or an opportunity to resolve the issue.

11. Changes, governing law and disputes

We may update these terms to reflect changes to AikoAI, law or provider requirements. We will post the updated terms here and, for material changes, provide additional notice where appropriate.

These terms are governed by the laws of England and Wales. If you are a consumer elsewhere in the United Kingdom or another country, you retain any mandatory protections and rights to bring proceedings that apply where you live. Please contact us first so we can try to resolve any concern informally.
