Terms of Service

Effective 1 September 2026. Last updated 1 September 2026.

These Terms of Service (the "Terms") are a legal agreement between Yin Yang, Inc., a Delaware corporation trading as Elaichi ("Elaichi", "we", "us"), and the organization that subscribes to or uses the Service ("Customer", "you").

Please read section 8 (Prohibited Data), section 12 (Termination and deletion), section 17 (Limitation of liability), and section 19 (Governing law and disputes) carefully. They limit our obligations to you and describe irreversible actions.

1. Acceptance and eligibility

By creating an account, accessing the Service, or executing an Order Form referencing these Terms, you agree to them.

The Service is offered only to businesses and organizations. It is not offered to consumers, is not directed to children, and may not be used for personal, family, or household purposes. You represent that you are at least 18 years old and that you have authority to bind the organization you represent. If you do not have that authority, do not use the Service.

2. Order of precedence

Where you and Elaichi have executed a Master Services Agreement or an Order Form, the documents govern in this order, with the earlier prevailing over the later on any conflict:

  1. The executed Master Services Agreement, if any
  2. The executed Order Form
  3. The Data Processing Agreement
  4. These Terms

Exception for data protection. On any question of data protection or the processing of personal data, the order is reversed in favour of the data protection terms: the Standard Contractual Clauses, then the Data Processing Agreement, then the Master Services Agreement, then the Order Form, then these Terms.

3. The Service

Elaichi is a hosted MCP control plane. It provides a connector catalog, credential vaulting, toolboxes, MCP endpoints, role-based access control, restrictions, and an audit log, as described at elaichi.ai. Plan entitlements are described on the pricing page or in your Order Form.

We may modify, improve, or discontinue features. Where we discontinue a material feature you rely on, we will give at least 30 days' notice to account administrators.

4. Accounts and security

You are responsible for your account, for your users' activity, and for the security of your credentials, API tokens, and MCP endpoint URLs. Tokens and endpoint URLs are displayed once at creation and cannot be retrieved afterwards. A lost endpoint can be rotated, which revokes the old token and issues a replacement, but it cannot be recovered. Store them securely. Notify us at [email protected] promptly if you suspect unauthorized access.

You are responsible for configuring roles, restrictions, and toolbox scope appropriately for your organization. The Service gives you the controls; it does not decide your policy for you.

5. Customer Data and ownership

As between the parties, you own all Customer Data, the content, records, credentials, and personal data your organization submits to, or makes reachable through, the Service.

You grant us a limited, non-exclusive, worldwide license to host, process, and transmit Customer Data solely to provide, secure, and support the Service, and as further described in the Data Processing Agreement, which is incorporated into these Terms by reference.

We do not train, fine-tune, or improve any model on Customer Data or tool-call content, and we do not log prompts or completions.

6. Aggregated data

We may generate and use aggregated, de-identified statistics about use of the Service, such as feature adoption, error rates, and performance, to operate, secure, benchmark, and improve it. Such data will never identify you, your users, or your Customer Data, and we will not disclose it in any form that does.

7. Acceptable use

You will not, and will not permit any user to:

  1. access or attempt to access another organization's data or workspace;
  2. use the Service to violate any law, or to infringe or misappropriate any third party's rights;
  3. reverse engineer, decompile, or attempt to derive source code from the Service, except to the extent that restriction is unenforceable by law;
  4. probe, scan, or test the vulnerability of the Service, or breach or circumvent any security or authentication measure, except under our published vulnerability disclosure policy;
  5. use the Service to transmit malware or to send unsolicited communications;
  6. resell, sublicense, or provide the Service to a third party as a standalone service bureau offering;
  7. use the Service to build a competing product; or
  8. exceed documented rate limits, or interfere with the integrity or performance of the Service.

8. Prohibited Data

This section is a material condition of your right to use the Service.

Connectors can reach any API you authorize, so the boundary of what may flow through Elaichi is contractual rather than technical. You will not submit to the Service, or make reachable through it, any of the following:

  • Protected health information governed by HIPAA or comparable health privacy law. We do not offer a Business Associate Agreement by default, and the Service is not configured for HIPAA workloads. PHI may be submitted only where an Order Form expressly permits it and a Business Associate Agreement has been executed between the parties.
  • Payment card data, primary account numbers, cardholder data, or sensitive authentication data governed by PCI DSS.
  • Biometric identifiers or biometric information as defined under BIPA or comparable law.
  • Government-issued identification numbers, financial account credentials, or special category data under GDPR Article 9, except where expressly agreed in writing in an Order Form.
  • Data subject to ITAR, EAR classification above EAR99, or comparable export control regimes.

You are responsible for ensuring your connections, toolboxes, and restrictions do not expose Prohibited Data. If you become aware that Prohibited Data has entered the Service, notify us immediately at [email protected]. We may suspend affected connections without liability.

9. Third-party services and connectors

The Service connects to third-party products at your direction. Your use of each one remains governed by your own agreement with that provider, and you are responsible for complying with it, including any restriction on automated access, rate limits, or scope of authorized use.

We do not control third-party services. We are not liable for their availability, accuracy, security, changes to their APIs, or termination of your access to them. A third party changing or withdrawing its API may degrade or disable a connector, and that is not a breach of these Terms.

10. AI model providers

The in-product assistant operates on your own model provider key. Elaichi holds no model provider key of its own for this purpose. When you supply a key for Anthropic, OpenRouter, Fireworks, or any OpenAI-compatible endpoint, calls are made to your account, under your agreement with that provider, and your content is transmitted to it.

You are responsible for selecting a provider whose terms, data handling, and retention meet your obligations. We are not a party to that agreement, make no representation about that provider, and are not liable for its processing of your content.

11. Fees, trials, and renewal

Trial. New organizations receive a 14-day Gold trial. At trial end, plan-gated features lock. Nothing is deleted, subscribe to resume.

Fees and billing. Fees are as stated on the pricing page or in your Order Form, billed monthly or annually as you elect, in advance, through Stripe. Fees are exclusive of taxes, which you are responsible for other than taxes on our income.

Renewal. Subscriptions renew automatically for successive terms of the same length unless either party gives 30 days' notice before the end of the then-current term.

Price changes. We will give at least 30 days' notice before the start of a renewal term of any change to fees. The change takes effect at renewal.

No refunds. Fees are non-refundable. No credit is given for partial periods, unused capacity, or features you did not use. This does not limit any non-waivable statutory right.

Non-payment. We may suspend the Service if fees are more than 15 days overdue, after notice.

12. Term, termination, and deletion

Term. These Terms run from your first use until all subscriptions have expired or terminated.

Termination for convenience. You may cancel at any time, effective at the end of the then-current term. See "No refunds" above.

Termination for cause. Either party may terminate on 30 days' written notice of a material breach that remains uncured. We may suspend or terminate immediately for a breach of section 7 or section 8, or where continued operation poses a security or legal risk.

Deletion. Deleting an organization has two effects, on different timelines:

  • Access is revoked immediately. All API tokens, MCP endpoint URLs, and connections stop serving the moment deletion is requested, regardless of the recovery period below. Third-party credentials are revoked at the provider, so restoring an organization does not restore its connections, every connection must be re-established.
  • Data enters a 30-day recovery period. The workspace is locked and billing stops. During this period an owner may restore the organization. At the end of it, all Customer Data, including audit history and usage counters, is permanently deleted.

⚠️ Immediate permanent deletion. An owner may instead purge the organization at once, skipping the recovery period. This is irreversible. There is no restore path, and we cannot reconstruct the data.

Export before the recovery period ends. The Service does not provide a bulk export or CSV download. Customer Data, including the audit log, is readable through the API, cursor-paginated, and audit records can be forwarded continuously to a customer-configured Datadog destination. Retrieve anything you need through those mechanisms before the recovery period expires. We are under no obligation to reconstruct data once it is permanently deleted.

Survival. Sections 5, 6, 8, 12, 13, 14, 17, 18, 19, 20, 21, and 23 survive termination, together with your obligation to pay fees accrued before it.

13. Confidentiality

Each party will protect the other's confidential information with at least reasonable care, use it only to perform under these Terms, and disclose it only to personnel and advisors bound by comparable obligations. This does not apply to information that is public through no fault of the recipient, independently developed, or rightfully received from a third party. A party compelled by law to disclose may do so, giving prompt notice where legally permitted.

14. Intellectual property and feedback

We retain all right, title, and interest in the Service, our software, documentation, connectors, and brand. No rights are granted except as expressly stated.

If you send us feedback, suggestions, or feature requests, you grant us a perpetual, irrevocable, royalty-free license to use them without obligation or attribution. You are not required to send feedback.

15. Publicity

We may identify you as a customer, using your name and logo, on our website and in sales materials. You may opt out at any time by emailing [email protected], and we will remove the reference within 30 days.

16. Beta features

Features designated beta, preview, early access, or experimental are provided as is, may be changed or withdrawn without notice, are excluded from any support or availability commitment, and should not be used for production workloads or Customer Data you cannot afford to lose.

17. Warranties, disclaimers, and availability

We warrant that we will provide the Service with reasonable skill and care, and in accordance with the security measures described in the DPA.

Availability. We provide the Service using commercially reasonable efforts. Except where an Order Form or Master Services Agreement expressly sets out a service level agreement with credits, we make no uptime commitment and offer no service credits. Support is provided as described in your Order Form.

EXCEPT AS EXPRESSLY STATED, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE MAXIMUM EXTENT PERMITTED BY LAW WE DISCLAIM ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE AGAINST EVERY THREAT, OR THAT ANY THIRD-PARTY SERVICE WILL REMAIN AVAILABLE.

AI output. Output produced by an AI model through the Service may be inaccurate. You are responsible for reviewing it before relying on it or acting on it.

18. Indemnification

By you. You will defend and indemnify us against third-party claims arising from your Customer Data, your breach of section 7 or section 8, your use of a third-party service in breach of its terms, or your violation of law.

By us. We provide intellectual property infringement indemnification only where expressly agreed in an executed Master Services Agreement. These Terms alone do not include an indemnity from us.

19. Limitation of liability

NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, OR FOR LOST PROFITS, REVENUE, GOODWILL, OR DATA, EVEN IF ADVISED OF THE POSSIBILITY.

EACH PARTY'S TOTAL AGGREGATE LIABILITY IS LIMITED TO THE FEES PAID OR PAYABLE BY YOU IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, except where an executed Order Form or Master Services Agreement sets a different limit, in which case that limit governs.

These limits do not apply to your payment obligations, your indemnity obligations, or either party's liability for fraud, willful misconduct, or any liability that cannot be excluded by law.

20. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws rules. The UN Convention on Contracts for the International Sale of Goods does not apply.

Escalation first. Before filing, the parties will escalate the dispute to an executive of each and attempt to resolve it in good faith for 30 days. Completing this step is a condition precedent to filing suit, and any applicable limitation period is tolled while escalation is under way, so neither party need file merely to preserve a claim.

Venue. Any dispute not resolved through escalation will be brought exclusively in the state or federal courts located in the State of Delaware, and each party submits to their personal jurisdiction.

Jury waiver. EACH PARTY WAIVES ANY RIGHT TO A TRIAL BY JURY.

Injunctive relief. Either party may seek injunctive or equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information, without first completing escalation.

21. Compliance with trade laws

You represent that you are not located in, and will not use the Service in, a country subject to comprehensive US sanctions, and that you are not on any US restricted-party list. You will comply with all applicable export control and sanctions laws.

22. Changes to these Terms

We may update these Terms. For material changes we will give at least 30 days' notice to account administrators by email or in-product notice. Continued use after the effective date constitutes acceptance. If you do not agree, you may terminate before the change takes effect; section 11's no-refund provision still applies.

23. General

Assignment. Neither party may assign these Terms without the other's consent, except to a successor in a merger, acquisition, or sale of substantially all assets, on notice.

Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control.

Notices. Legal notices to us: [email protected], and Yin Yang, Inc., 9450 SW Gemini Dr, PMB 69868, Beaverton, Oregon 97008‑7105, USA. To you: the administrator email addresses on your account.

Severability and waiver. If a provision is unenforceable, the rest remains in effect. A failure to enforce is not a waiver.

Independent contractors. The parties are independent contractors. Nothing creates a partnership, agency, or employment relationship.

Entire agreement. These Terms, with the documents listed in section 2, constitute the entire agreement and supersede all prior understandings.
