Terms of Service

1. Acceptance of Terms

By accessing or using Yarne, you agree to these Terms of Service. If you are using Yarne on behalf of a business, school, organization, or other entity, you represent that you have authority to bind that entity to these Terms.

2. Service Description

Yarne is a small-business operations platform for tutoring schools and coaching businesses. The Service includes CRM records, public inquiry forms, customer portals, student profiles, class enrollment, waitlists, attendance, make-up tracking, class transfers, slot booking, payment tracking, payment slip upload and verification, reminders, broadcasts, owner alerts, reports, receipts, LINE account-linking tools, and AI-assisted workflows.

3. Account Responsibilities

You are responsible for your account credentials, for activity under your account, and for keeping your organization, contact, billing, and notification information accurate. You must promptly notify us if you believe your account has been compromised.

4. Customer Data and Permissions

You retain ownership of the business records, client records, student records, payment data, uploaded files, messages, and other content you submit to Yarne. You are responsible for having the rights, permissions, notices, and consents required to enter that data into the Service, including any information about children, parents, students, clients, or staff.

If you operate a school or child-focused program, you are responsible for parent, guardian, school, or other legally required consent before collecting or processing student details such as dates of birth, addresses, caregiver information, personality notes, special care notes, attendance, make-up records, class transfers, or payment status. Yarne is provided for adult business administrators, parents, guardians, and authorized users; children should not create their own Yarne accounts.

5. Customer Payments and School Policies

Customer payments tracked inside Yarne remain transactions between you and your customers. Yarne does not initiate bank transfers, hold school funds, guarantee payment, decide tuition, issue refunds, set make-up rules, approve class transfers, or resolve parent disputes for you. You are responsible for confirming the correct payment account, reviewing slips, applying payments, issuing receipts, and communicating your own enrollment, transfer, make-up, refund, discount, and cancellation policies.

6. Yarne Subscription Billing

Subscription fees, if applicable, are billed through our payment provider. Unless a separate written agreement says otherwise, subscription fees are billed in advance and cancellations take effect at the end of the current billing period. Trials, discounts, and account status are governed by your Yarne billing arrangement unless a separate written agreement says otherwise.

7. AI and Automation

Yarne may use AI services to read payment slips, summarize records, help draft communications, and support other automation features. AI outputs can be incomplete or incorrect. You remain responsible for reviewing important outputs, especially payment, customer, compliance, and communication decisions.

If you enable the LINE AI assistant, you are responsible for deciding the assistant's mode, tool permissions, budget limits, business facts, escalation rules, and customer disclosures. The assistant must not be used for unlawful, deceptive, abusive, or high-risk advice. You are responsible for monitoring AI-generated replies shown to your customers and for taking over conversations when a human response is appropriate.

AI-generated answers are provided without any warranty of accuracy, completeness, or availability. Yarne may disable or limit AI features that exceed configured budgets, create operational risk, violate these Terms, or depend on unavailable third-party providers.

8. Portals, Messaging, and LINE

Portal links, LINE account-linking, payment instructions, broadcasts, reminders, and customer messages must be used only for lawful business administration and customer support. You are responsible for sending messages only to people you are allowed to contact, honoring opt-outs or deletion requests where required, and keeping secure portal links and receiving-account details from being shared publicly or misused.

9. Acceptable Use

You may not use Yarne to violate law, infringe rights, transmit malicious code, abuse messaging channels, attempt unauthorized access, interfere with the Service, or store content that is unlawful, deceptive, harmful, or outside the scope of ordinary business administration.

You may not use Yarne to collect children's information without required authority or consent, expose private bank account details on public pages, impersonate another organization, spam LINE or email recipients, upload fraudulent payment slips, or rely on AI output as the sole basis for high-risk legal, medical, financial, educational, or safety decisions.

10. Third-Party Services

Yarne depends on third-party providers for hosting, database, storage, authentication, AI processing, email, payments, messaging, analytics, and related infrastructure. Their own terms and availability may apply to those services. Open-source dependency notices are summarized in the project's third-party notices.

11. School-Specific Notices and Translations

You may provide your own enrollment terms, parent notices, privacy notices, consent language, translations, or school-specific policy summaries to your customers. You are responsible for making sure those materials are accurate, legally sufficient, and consistent with your actual operations. If you provide translated summaries, you should tell customers whether the translated text or the English text controls.

12. Intellectual Property

Yarne and its software, design, workflows, branding, and documentation are owned by Yarne or its licensors. These Terms do not grant you ownership of Yarne software or branding. You may use the Service only as permitted by these Terms.

13. Service Changes and Suspension

We may update, suspend, or discontinue parts of the Service. We may suspend or terminate access if we reasonably believe you violated these Terms, created security risk, failed to pay applicable fees, or used the Service in a way that could harm Yarne, customers, providers, or other users.

14. Disclaimers and Liability

The Service is provided "as is" and "as available" to the fullest extent permitted by law. Yarne is not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost revenue, lost data, or business interruption, except where liability cannot be limited by applicable law.

Yarne does not provide legal, tax, accounting, banking, child-safety, medical, educational, or financial advice. Operational tools, reports, reminders, AI outputs, and suggested messages are workflow aids and must be reviewed by you before relying on them for important decisions.

15. Changes to These Terms

We may update these Terms from time to time. Continued use of the Service after an update means you accept the updated Terms.
