Terms of Service
1. Scope
These Terms of Service (the "Terms") govern your use of four-talk (the "Service"). By using the Service, you agree to these Terms as well as any related policies, guidelines, or supplemental conditions displayed or referenced in connection with the Service.
The authoritative version of these Terms is the Japanese version. English and other translated versions are provided for convenience only. In the event of any inconsistency, the Japanese version will prevail.
2. Description of the Service
The Service is a global communication service where users from around the world gather at the top of each hour and join anonymous four-person voice conversations. The Service may include AI-based matching, automatic translation, talk history, billing features, and related support tools.
Specific features, availability, supported devices, supported languages, operating hours, and eligibility conditions may change, be added, or be suspended based on operational needs, external service dependencies, legal requirements, or security considerations.
3. Eligibility
You may use the Service only if you are 19 years of age or older, if doing so is lawful in your country of residence or place of use, and if you meet any additional minimum age requirements that apply under local law. In some jurisdictions, minors may need consent from a parent or legal guardian.
You must provide truthful and accurate information regarding your age, country of residence, consent status, and other registration details, and you must update that information promptly if it changes.
4. Account Management
You are responsible for managing your account and authentication methods. You may not allow third parties to use your account or transfer, lend, sell, or change the registered identity of your account.
We may refuse registration, suspend use, require identity verification, or take other necessary measures if we believe submitted information is false, incomplete, impersonated, or associated with misuse.
5. Prohibited Conduct
You may not engage in illegal conduct, conduct against public order or morality, infringement of third-party rights, discrimination, hate speech, harassment, threats, defamation, fraud, impersonation, praise of terrorism, child exploitation, illegal drug trading, financial crime solicitation, sexual exploitation, spam, service disruption, reverse engineering, unauthorized access, bot usage, or any other conduct we consider inappropriate.
You must also refrain from statements, topic submissions, profile displays, solicitations, or other conduct that is unlawful or seriously inappropriate not only in your own jurisdiction but also in the jurisdictions of your conversation partners where relevant.
6. Recording, AI Features, and Anonymous Use
The Service is designed for anonymous participation. You may not record, film, screen-capture, reproduce, redistribute, or share talks with third parties. This restriction does not limit records we maintain where required by law or necessary for safety, audits, or fraud prevention.
The Service uses automated features such as AI-based matching, automatic translation, speech recognition, and fraud detection. Translation quality, speech-recognition quality, naturalness of expression, network quality, and related performance may vary by language, region, network conditions, device, and third-party service availability, and are not guaranteed.
You represent that you have the necessary rights to any topics, statements, or other content you provide and that such content may be processed as needed to operate the Service.
7. Billing and Subscriptions
The paid feature of the Service is a subscription. On iOS, billing is handled through App Store In-App Purchase; on Android, through Google Play Billing; and on the web, through Stripe.
Displayed currency, tax handling, currency conversion, automatic renewal, billing date, cancellation method, receipt issuance, refund channel, and other billing conditions are governed by the relevant platform or payment provider. You are responsible for checking the latest terms displayed by that platform before purchase.
Recurring subscriptions may renew automatically unless canceled through the relevant platform. Renewal management, cancellation timing, and billing dates are determined by the relevant platform's systems.
7-2. Talk Time Entitlements
An active subscription grants talk time entitlements according to your plan. Entitlements are measured in minutes and are available only on the platform (iOS, Android, or web) through which your subscription was purchased.
Talk time entitlements are consumed in first-in-first-out (FIFO) order, prioritizing entitlements with the nearest expiration date. Unused entitlements expire at the end of their validity period and cannot be rolled over.
On web (Stripe), if you leave a talk, the unconsumed portion of entitlements from the moment of departure is immediately returned (rounded up to the nearest minute) and retains its original expiration date. On iOS and Android, talk time consumption is completed at the start of the talk; no entitlements are returned if you leave early. If a matching session times out due to insufficient participants, no entitlements are consumed regardless of platform.
For Web (Stripe) users: if your talk time entitlements are exhausted after a talk, the shortfall amount (in yen) accumulates automatically. When the accumulated amount reaches ¥10,000, it is charged immediately to your registered payment method. Any outstanding accumulated amount is also charged in full on your subscription renewal date or when you request account deletion. On iOS and Android, post-talk billing does not apply; insufficient entitlements prevent new talk sessions from starting.
Coupons and talk time entitlements issued by the Service are usage rights valid only within the Service. They may not be converted to cash or any cash equivalents, and may not be transferred, sold, or lent to any third party. No compensation is provided for entitlements that expire unused.
7-3. Expiration and Entitlement Expiry Notifications
Talk time entitlements have an expiration date. Subscription grants, referral rewards, and continuation bonuses expire exactly 150 days from the grant date. Entitlements granted via other coupons expire on a per-coupon basis, up to a maximum of 150 days.
You will receive notifications three days, one day, and on the day before expiration via in-app and push notifications. Email notifications are also sent to users who have enabled email notifications.
If push notifications cannot be delivered (e.g., app is uninstalled), we consider sending to the registered email address to constitute reasonable notification effort.
8. Refunds and Cancellations
As a rule, the Service does not process refunds directly within the app. Whether refunds, reversals, chargebacks, or other payment remedies are available depends on the applicable platform (iOS: App Store, Android: Google Play, Web: Stripe) and law.
If you wish to request a refund, please follow the standard procedures provided by your platform. We are not responsible for refund decisions made by each platform.
Nothing in these Terms limits non-waivable consumer rights such as withdrawal rights, cancellation rights, statutory refund rights, or other consumer protections granted by mandatory law in your country of residence.
9. Intellectual Property
All intellectual property rights in the Service, app, website, design, logos, software, text, images, databases, and related materials belong to us or our legitimate licensors.
You may not reproduce, modify, redistribute, or otherwise use Service content beyond what is necessary to use the Service as intended.
10. Suspension and Termination
We may suspend or terminate your access, restrict your account, or remove content without prior notice if you violate these Terms, if required by law or regulators, if safety or operational needs require action, if fraud or misuse is suspected, or if payment obligations are not met.
If you receive a threshold number of reports from other users, we apply graduated measures: first a warning, then a temporary suspension of talk features (48 hours), and ultimately permanent suspension depending on the cumulative count. During a suspension, you retain access to basic functions such as signing in, contacting support, and adjusting settings. You may appeal any temporary or permanent suspension through the in-app inquiry feature.
You may request account deletion through the procedures provided in the app. Post-termination data handling is governed by the Privacy Policy and applicable law.
11. Disclaimer and Limitation of Liability
The Service is provided on an "as is" basis. We do not guarantee completeness, accuracy, fitness for a particular purpose, uninterrupted availability, absence of defects, or non-infringement.
We are not responsible for disputes between users, communication failures, device issues, outages of third-party services, translation errors, speech-recognition errors, processing by payment providers or app stores, changes in law, or other causes beyond our reasonable control.
To the maximum extent permitted by applicable law, our liability is limited to direct and ordinary damages and shall not exceed the amount paid by the relevant user to the Service during the 12 months preceding the event giving rise to the claim, except where such limitation is not allowed by law or where we acted intentionally or with gross negligence.
Even after content is removed or taken down from the Service, cached copies may persist in browsers, CDNs, search engines, or other third-party services, and we have no control over content that has already been copied or redistributed by users or third parties. We are not liable for damages arising from such cached or reproduced content.
12. International Availability and Legal Compliance
The Service is offered globally, but some features may be unavailable depending on country of residence, current location, payment method, economic sanctions, export controls, app-store rules, local law, or other legal or operational constraints. We may restrict or block registration, purchases, or access in specific countries or regions where necessary.
You may not use the Service for any purpose that violates economic sanctions, export-control laws, anti-organized crime requirements, or other mandatory laws. If we suspect such violations, we may refuse payment, suspend access, restrict the account, or take other necessary action.
13. Changes to the Terms
We may amend these Terms in response to changes in law, service features, security requirements, billing conditions, or operational policies.
Where changes are material, we may provide notice through in-app messaging, website publication, email, or other reasonable means. Continued use of the Service after such changes may be treated as acceptance of the updated Terms where permitted by law.
14. Governing Law and Jurisdiction
These Terms and all matters related to the Service are governed by the laws of Japan.
Any dispute arising out of or relating to the Service shall be subject to the exclusive jurisdiction of the courts of Japan as the court of first instance, except to the extent mandatory consumer-protection laws grant users a different forum or protection that cannot be waived.
15. Severability and Contact
If any provision of these Terms is held invalid or unenforceable in a particular country or region, that provision will be interpreted or modified only to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
For questions about these Terms, please contact us through the in-app support flow or the instructions published on the Service website.
