Terms of Service

These Terms govern access to and use of the StackYapper websites, hosted portal, MCP endpoints, connectors, agent workflows, and related services (the “Service”).

The Service is provided by Symao Systems, doing business as StackYapper (“StackYapper,” “we,” “us,” or “our”), located at 2106 Morthland Drive #1079, Valparaiso, Indiana 46383, United States.

1. Agreement and authority

By clicking to accept, completing a purchase, signing an order form, or using the Service after acceptance, you agree to these Terms and the documents incorporated into them, including the Acceptable Use Policy, Billing and Cancellation Policy, and, when StackYapper processes personal data on Customer’s behalf, the Data Processing Addendum. The Privacy Policy describes StackYapper’s data practices and is acknowledged separately. If you use the Service for an organization, you represent that you may bind that organization. “Customer” means that organization. The Service is offered only for business and professional use, not personal, family, or household use. You must be at least 18 years old and able to form a binding contract.

2. The Service

StackYapper provides a hosted control plane that lets Customer connect approved business systems to Customer-selected AI clients and workflows. Features may be added, changed, suspended, or discontinued. Beta, preview, catalog-only, and “coming soon” features are provided for evaluation and may be incomplete or unavailable.

3. Accounts and administration

Customer is responsible for its users, administrators, identity provider, API credentials, permissions, connector configuration, AI-client configuration, and all activity under its account. Customer must secure and administer its identity-provider environment, require appropriate multifactor authentication, use least-privilege credentials and permissions, promptly remove access that is no longer needed, and notify security@stackyapper.dev of suspected compromise.

4. Customer-controlled access and actions

StackYapper relies on Customer’s configured single sign-on provider to authenticate Customer users. Customer acknowledges that a person authenticated by Customer’s identity provider may be treated as authorized to act through the roles and permissions assigned to that identity. Customer is responsible for preventing, detecting, and responding to compromise of Customer-managed identities, sessions, authenticators, email accounts, identity-provider tenants, endpoints, connected-service credentials, API tokens, and third-party systems.

Customer controls which connectors, tools, users, groups, permissions, and risk classes it enables. Some tools can create, update, send, execute, revoke, disable, move, or delete data or resources in connected systems (“Write Actions”). Customer is responsible for reviewing tool descriptions and confirmation prompts, granting Write Actions only to authorized personnel and agents, maintaining backups and recovery procedures, testing workflows, supervising AI-generated instructions and output, and confirming that each requested action is intended before execution. Confirmation controls reduce risk but do not guarantee that an authorized or compromised user, agent, workflow, identity provider, or connected system will not request an unintended action.

Customer authorizes StackYapper to create and make available operational, administrative, security, usage, confirmation, and outcome audit records concerning Customer’s users, agents, clients, connectors, customer workspaces, and tool activity. MSP administrators may receive audit visibility across customer workspaces they are authorized to manage. Customer is responsible for providing any notices and establishing any workplace, monitoring, or acceptable-use policies required for its users.

To the maximum extent permitted by law, StackYapper is not responsible for unauthorized access, disclosure, alteration, deletion, execution, loss, or other harm resulting from (a) compromise or misuse of a Customer-managed account, identity provider, authenticator, endpoint, credential, token, AI client, workflow, or connected service; (b) Customer’s permissions, configuration, instructions, or failure to revoke access; or (c) a Write Action requested through an authenticated and authorized Customer context. This allocation does not excuse StackYapper from responsibility to the extent harm was caused by StackYapper’s breach of these Terms, the DPA, applicable law, or security obligations expressly undertaken by StackYapper.

5. Customer data and instructions

Customer retains its rights in data submitted to or accessed through the Service. Customer instructs StackYapper to process that data only to provide, secure, support, and improve the Service; prevent abuse; and comply with law. Customer represents that it has all rights, notices, consents, and lawful bases needed for the data and instructions it supplies, including data concerning Customer’s clients, personnel, and end users.

The Service sends requested results to the AI client or automation system Customer chooses. Those systems and connected vendors are governed by Customer’s agreements with them. Customer is responsible for reviewing AI output and must not rely on it as a substitute for professional judgment.

6. Confidentiality

Each party will protect the other party’s nonpublic confidential information using reasonable care and use it only to perform under these Terms. These duties do not apply to information that is public without breach, already known without restriction, independently developed, or lawfully received from another source. A recipient may disclose information when legally required after giving notice when permitted.

7. Acceptable use

Customer must comply with the Acceptable Use Policy. Customer may not bypass access controls, use the Service to violate law or third-party rights, introduce malicious code, conduct unauthorized security testing, resell or sublicense the Service except under a signed agreement, or use output without appropriate human review where harm could result.

8. Fees, renewal, and taxes

Paid plans are billed in advance and renew automatically for successive billing periods until canceled. Current self-service pricing is shown before checkout. Customer authorizes StackYapper and its payment processor, Stripe, to charge the selected payment method for recurring fees, usage or quantity adjustments shown at checkout, and applicable taxes. The Billing and Cancellation Policy is incorporated into these Terms.

9. Intellectual property and feedback

StackYapper and its licensors own the Service, software, documentation, branding, and all related intellectual-property rights. Subject to these Terms, Customer receives a limited, nonexclusive, nontransferable right to use the Service during its subscription. Customer grants StackYapper a perpetual, worldwide right to use feedback without restriction or payment, without identifying Customer publicly.

10. Third-party services

Connected services, identity providers, payment services, AI clients, and other third-party products are not controlled by StackYapper. StackYapper is not responsible for their availability, acts, terms, output, or data practices. Customer authorizes the exchanges it configures with them.

11. Suspension and termination

Customer may stop using the Service or cancel a subscription as described in the Billing Policy. StackYapper may suspend or terminate access for material breach, nonpayment, security risk, unlawful use, harm to the Service or others, or when required by law. When practicable, StackYapper will give notice and an opportunity to cure. Provisions that by their nature should survive termination will survive.

12. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” STACKYAPPER DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND WARRANTIES ARISING FROM COURSE OF DEALING. STACKYAPPER DOES NOT WARRANT UNINTERRUPTED OR ERROR-FREE OPERATION, THAT OUTPUT IS COMPLETE OR ACCURATE, OR THAT THE SERVICE WILL MEET EVERY COMPLIANCE REQUIREMENT.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, REVENUE, BUSINESS, GOODWILL, OR DATA. EACH PARTY’S TOTAL LIABILITY ARISING OUT OF THE SERVICE WILL NOT EXCEED THE FEES CUSTOMER PAID OR OWED FOR THE SERVICE DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY. These limits do not apply where liability cannot legally be limited or to Customer’s payment obligations, misuse of the other party’s intellectual property, or violation of the Acceptable Use Policy.

14. Indemnity

Customer will defend and indemnify StackYapper against third-party claims arising from Customer data, Customer’s connected services or AI-client use, or Customer’s unlawful or unauthorized use of the Service. StackYapper will promptly notify Customer and reasonably cooperate; Customer may not settle a claim in a way that admits fault or imposes obligations on StackYapper without consent.

15. Dispute resolution; binding arbitration; class waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES MOST DISPUTES TO BE RESOLVED THROUGH BINDING INDIVIDUAL ARBITRATION RATHER THAN IN COURT, AND IT WAIVES THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION.

Informal resolution first. Before filing any claim, the party asserting a dispute must send the other party written notice describing the dispute and the relief sought (notices to StackYapper: legal@stackyapper.dev). The parties will attempt in good faith to resolve the dispute within sixty (60) days of the notice. This paragraph does not delay either party’s right to seek the interim relief described below.

Agreement to arbitrate. Except as provided in the small-claims and injunctive-relief carve-outs below, any dispute, claim, or controversy arising out of or relating to these Terms or the Service — including their formation, interpretation, breach, or termination, and including whether a claim is subject to arbitration — will be resolved by final and binding arbitration administered by the American Arbitration Association (“AAA”) under its Commercial Arbitration Rules in effect when the arbitration is commenced. The Federal Arbitration Act governs the interpretation and enforcement of this Section. Judgment on the award may be entered in any court of competent jurisdiction.

Procedure. The arbitration will be conducted in English by a single arbitrator. The seat of the arbitration is Porter County, Indiana; hearings may be conducted by videoconference unless either party requests an in-person hearing or the arbitrator orders otherwise. Each party bears its own attorneys’ fees and costs except where the claim permits fee-shifting by statute or the arbitrator finds a claim or defense frivolous. AAA filing, administrative, and arbitrator fees are allocated per the AAA Commercial Rules. The arbitrator may award any relief a court of competent jurisdiction could award to the individual party and must issue a reasoned written decision.

Small claims. Either party may instead bring an individual claim in small claims court in a court of competent jurisdiction, so long as the claim remains in that court and is not removed or appealed to a court of general jurisdiction.

Injunctive relief. Either party may seek temporary, preliminary, or permanent injunctive or other equitable relief in the state or federal courts serving Porter County, Indiana (whose jurisdiction and venue both parties accept for this purpose) for actual or threatened infringement or misappropriation of intellectual property, breach of confidentiality obligations, or unauthorized access to or abuse of the Service, without first engaging in informal resolution or arbitration, and without posting a bond except as required by law.

CLASS ACTION AND JURY WAIVER. ALL CLAIMS MUST BE BROUGHT IN THE PARTIES’ INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PARTY’S CLAIMS OR PRESIDE OVER ANY FORM OF CLASS OR REPRESENTATIVE PROCEEDING. EACH PARTY WAIVES THE RIGHT TO A TRIAL BY JURY. If this class waiver is held unenforceable as to a particular claim, that claim (and only that claim) must proceed in the courts identified in the injunctive-relief paragraph, and any such proceeding will be stayed pending arbitration of all arbitrable claims.

Coordinated filings. If twenty-five (25) or more demands for arbitration raising similar claims and coordinated by the same or related counsel are filed against either party, the demands will be resolved in staged proceedings: the AAA will administer an initial set of up to ten (10) bellwether arbitrations; remaining demands will not be filed (and no filing fees will accrue) until the bellwether set is resolved, after which the parties will engage in a global mediation before further staged sets proceed. Statutes of limitation are tolled for demands held under this paragraph from the date a compliant informal-resolution notice is received.

Severability and survival. If any provision of this Section other than the class waiver is held unenforceable, it will be severed and the remainder enforced. This Section survives termination of these Terms. Changes to this Section apply prospectively to disputes arising after the change takes effect.

16. Governing terms

Order forms and signed agreements control over conflicting online terms. These Terms are governed by Indiana law, without regard to conflict-of-law principles, except that the Federal Arbitration Act governs the arbitration agreement in Section 15. Subject to Section 15, the state and federal courts serving Porter County, Indiana have exclusive jurisdiction over disputes not required to be arbitrated, and each party consents to venue there. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

17. Changes and contact

StackYapper may update these Terms prospectively. Material changes will be communicated through the Service or account email before they take effect when required. Continued use of the Service after the effective date constitutes acceptance of the updated Terms. If applicable law or the nature of a change requires affirmative consent, StackYapper may request it separately. Nonmaterial changes may take effect when posted. StackYapper records the organization, accepting user, policy version, and server time when electronic acceptance is collected. Questions: legal@stackyapper.dev.
