Sumchat Terms of Service

Effective date: September 27, 2026 · Version 1.0

These Terms of Service (these "Terms") are a binding agreement between Kaitlian LLC, a California limited liability company with its principal office at 2108 N St #17084, Sacramento, California 95816 ("Sumchat," "we," "us"), and the person or entity that creates or administers a Sumchat workspace ("Customer," "you"). They govern your access to and use of the Sumchat platform; the hosted workspace, the AI agents that work in it, the websites and applications it builds and hosts, and every related service we provide (together, the "Services").

Please read these Terms carefully. Section 17 contains an arbitration agreement and class-action waiver that affect how disputes between us are resolved.

These terms describe Sumchat from the date above. For an existing customer, a material change takes effect only after the notice period in Section 19.1; earlier purchases, accrued rights, and refund commitments are preserved.

By creating an account, clicking to accept, or using the Services after the applicable effective date, you accept these Terms. If you accept on behalf of a company or other legal entity, you represent that you have authority to bind that entity, and "Customer" means that entity. If you do not agree, do not use the Services.

The following documents are part of these Terms and are incorporated by reference:

• the Acceptable Use Policy ("AUP");
• the AI Services Terms;
• the Privacy Policy;
• the Data Processing Addendum ("DPA"); and
• the Copyright & Content Complaints Policy.

If these Terms conflict with an incorporated document, the incorporated document controls for its subject matter.

1. The Services

Sumchat is a persistent AI assistant you work with through iMessage, with web pages for files, review, publishing, billing, and account access. It helps you edit media, manage files, build and host websites and internal applications, publish social content, communicate, and perform work with the Google Workspace connection you authorize. The Services include our software, hosting, AI assistants ("Agents"), tools, and pages at sumchat.ai, app.sumchat.ai, sumchat.link, and the customer-site addresses we operate.

We may improve, add, or change features of the Services at any time. If a change materially reduces the core functionality you pay for, we will give you reasonable advance notice where practicable.

2. Eligibility; accounts; members

2.1 Business use. The Services are offered for business and professional use. You must be at least 18 years old. The Services are not directed to children, and you may not use them if you are under 13 (see Section 8.6 regarding children's data on your own sites).

2.2 Accounts, workspaces and members. Your personal account is separate from the workspaces you join. A workspace belongs to its Customer. Owners manage members, brand access, connections, and shared billing. Teammates can work with and publish for assigned brands, subject to the Services' review and approval flows. You are responsible for whom you admit, the access you grant, and your members' compliance with these Terms. Actions taken by members within their authorized workspace access, including approving Agent actions, are attributed to that Customer. Joining a workspace does not give its owner access to your private personal work or Google connection.

2.3 Account security. Access uses your verified messaging identity and the sign-in methods we support. Protect your phone number, devices, sign-in codes and browser sessions. You are responsible for activity through your account except to the extent caused by our breach of these Terms. Notify us immediately at security@sumchat.ai if you suspect unauthorized access.

3. Agents, approvals, and your direction

3.1 Agents act at your direction. Agents perform work within your authorized personal or workspace context and with the capabilities and connections available there. You direct Agents through conversations, briefs, schedules, and approvals. As between you and Sumchat, work an Agent performs at your direction ; including content it drafts, sites it builds and publishes, messages it sends after your approval, and actions it takes with tools you connected, is your activity, and you are responsible for it as described in these Terms and the AI Services Terms.

3.2 Approval gates. Certain consequential actions (for example, publishing a website to the public internet, purchasing a domain, or posting to social media) require the explicit approval of a person in your workspace before they occur. Approval gates exist for your protection; approving an action confirms your direction to take it. You are responsible for reviewing what you approve.

3.3 No professional advice. Agents and the Services do not provide legal, tax, accounting, medical, financial, or other professional advice. Output that resembles professional advice ; including generated policies, contracts, or compliance reports, is general information and self-help material, not advice, and no attorney-client or other professional relationship is created. See the AI Services Terms for more.

4. Customer Content and intellectual property

4.1 Your content. "Customer Content" means (a) everything you or your members upload, submit, connect, or create in your workspace; (b) everything your Agents create at your direction, once you use, save, approve, or publish it (see the AI Services Terms for how ownership of AI-generated output works); and (c) content submitted to your published sites by your own end users, which you control as described in Section 8. As between you and Sumchat, you own Customer Content. These Terms transfer no ownership of Customer Content to us.

4.2 License to us. You grant Sumchat a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for technical purposes such as formatting, resizing, and transcoding), transmit, display, and distribute Customer Content, and to permit our subprocessors to do the same, solely as needed to provide, secure, and support the Services, including serving your published sites to their visitors, sending communications you direct, and generating previews. This license ends when the content is deleted from the Services, except for transient backup copies retained per our standard cycles and content we must retain to comply with law.

4.3 Your responsibilities for content. You are solely responsible for Customer Content: for having the rights to use and publish it, for its accuracy and legality, and for its compliance with the AUP. We have no obligation to monitor Customer Content, but we may remove or disable access to content that we reasonably believe violates these Terms, the AUP, or law.

4.4 Our IP. The Services, including our software, templates, Agent architecture, designs, and brand, are owned by Sumchat and our licensors. We grant you a limited, non-exclusive, non-transferable right to use them as part of the Services while your account is active. You may not copy, modify, reverse engineer, resell, or create derivative works of the Services except as allowed by law or these Terms. Template code and scaffolding that the Services place into your site or application source is licensed to you perpetually as part of your site, including after these Terms end.

4.5 Feedback. If you send us ideas or suggestions, we may use them without restriction or obligation to you.

4.6 DMCA. We respond to copyright complaints and maintain a repeat-infringer policy as described in the Copyright & Content Complaints Policy. We will terminate, in appropriate circumstances, the accounts of repeat infringers.

5. Acceptable use

Your use of the Services must comply with the AUP. Among other things, the AUP prohibits illegal content and conduct, infringement, malware and phishing, spam, deceptive practices (including undisclosed bots and fake reviews), and abuse of the platform or other tenants. We may investigate suspected violations and may suspend or remove content, sites, Agents, features, or workspaces as described in Section 12.

6. Third-party services and connections

6.1 Your connections. Sumchat supports a personal Google Workspace connection and authorized social account connections. Your use of a connected service is governed by that service's terms. You must have the right to connect each account and to authorize the actions you request. Google access currently requires review by the Sumchat team followed by your own Google consent. Team review is not Google verification and does not itself connect your account. Google may show an unverified-app notice while its verification is pending. The supported Google services and permissions are described on the Google Workspace page.

6.2 Credentials. Connection credentials remain in server-side custody. Raw Google tokens are not provided to the AI model or your browser. You may disconnect Google on the Google Workspace page or revoke access in your Google Account. Disconnecting stops future access through that connection; it does not delete content already copied into your work or cancel actions already scheduled with another provider. See the Google privacy disclosure.

6.3 Third-party dependencies. Parts of the Services are provided through third-party infrastructure and model providers (see our Subprocessors list). We are responsible for our subprocessors' handling of Customer Content under the DPA, but we are not responsible for third-party services you choose to connect.

6.4 Social publishing. Publishing to social networks is subject to each network's terms and policies, which you must follow. Networks may reject, remove, or label content and may revoke API access; we do not control them. You authorize us to post to accounts you connect only as directed through your workspace's publishing and approval flows. Political advertising through the Services' social publishing features is prohibited (see the AUP).

7. Communications features

7.1 You are the sender. The Services can place and answer phone calls and send messages, in each case on your behalf and at your direction. As between you and Sumchat, you are the sender, caller, and initiator of every communication sent through your workspace, and you are responsible for its content and for having any consent the law requires from its recipient.

7.2 Consent and compliance. Without limiting Section 7.1, you must: (a) not use the Services to send unsolicited commercial email, calls, or texts; (b) obtain and be able to demonstrate prior express consent, including prior express written consent where required; before directing any outbound call or text that uses an artificial or AI-generated voice or that contains marketing; (c) honor opt-outs promptly (and in any event within the timeframes required by law); (d) include the disclosures required for commercial email, including your valid physical postal address and a functioning unsubscribe mechanism; and (e) comply with the Telephone Consumer Protection Act, the CAN-SPAM Act, the California Invasion of Privacy Act, and every other applicable communications and privacy law.

7.3 Built-in disclosures. Customer-facing communications surfaces include automatic identification of Agents as AI (for example, AI-answered calls identify themselves and disclose recording). You must not remove, obscure, suppress, or instruct an Agent to suppress these disclosures.

7.4 Recording. Calls handled by the Services may be transcribed or recorded to provide the Services. You are responsible for any notice to and consent from call participants that applicable law requires (California requires all-party consent). The Services' built-in call disclosures assist with, but do not replace, your own compliance.

7.5 Suspension of sending. We may throttle, hold, or suspend outbound communications ; per message, per Agent, or workspace-wide; if we see complaint spikes, deliverability problems, legal risk, or AUP violations.

8. Published sites and your end users

8.1 What publishing means. When you publish a website through the Services, it becomes available to the public internet at addresses you choose (a sumchat.app address and/or your custom domains). You are the publisher and operator of your published sites. Sumchat hosts them as your service provider.

8.2 Your legal obligations as a site operator. You are solely responsible for your published sites' compliance with the laws that apply to you and your visitors, including without limitation: posting a privacy policy that meets the California Online Privacy Protection Act and other applicable privacy laws; accessibility of your site and its content to people with disabilities; truthful advertising and all-in price display (including California's Honest Pricing Law, and, for restaurant and food businesses, the required clear-and-conspicuous display of any mandatory surcharge with its purpose wherever prices appear); required disclosures for automated chat; consumer-review protections; and industry-specific rules that apply to your business. The Services provide templates, scaffolding, and review tools that help with these obligations; using them does not transfer the obligations to Sumchat, and Sumchat does not warrant that any site is compliant with law (see Section 3.3 and the AI Services Terms).

8.3 Your end users. Visitors and signed-in end users of your published sites are your users, not Sumchat's. You are the business/controller of the personal information your sites collect from them (visitor accounts, form submissions, orders, and similar); Sumchat processes it as your service provider/processor under the DPA. You are responsible for your own terms and privacy notices with your end users and for honoring their privacy rights.

8.4 Platform-reserved surfaces. Certain paths on published sites are served by the platform rather than your site code (for example, end-user sign-in, form submission, file serving, and the abuse-report door). We may add reserved surfaces and required platform notices (such as an abuse reporting link on platform-served pages) as needed to operate lawfully and safely.

8.5 Capacity and abuse protection. Published sites are subject to the storage capacity and usage limits disclosed for your workspace. Paid work and infrastructure use the funding and metering arrangements described in Section 10. We may limit traffic or compute to protect the Services from abuse.

8.6 Children. Your published sites must not be directed to children under 13, and you must not knowingly collect personal information from children under 13 through them, unless you first implement a COPPA-compliant program and notify us in writing at legal@sumchat.ai.

8.7 Takedown and site-level suspension. We may suspend or unpublish an individual site (without suspending your whole workspace) if we reasonably believe it violates the AUP or law, creates security or deliverability risk, or is the subject of a valid legal complaint. We will notify you and, where the problem is curable, give you a chance to cure.

9. Domains

9.1 Registrar. Domain purchases through the Services are registrations with Cloudflare, Inc., an ICANN-accredited registrar, under Cloudflare's Domain Registration Agreement, which you accept when you purchase. You are the registrant and owner of domains you purchase; the contact information you supply is submitted to the registrar. Your registration is subject to ICANN policies, including the Registrants' Benefits and Responsibilities, the Uniform Domain-Name Dispute-Resolution Policy, and the Transfer Policy. You may transfer a domain away at any time subject to ICANN's rules (including the 60-day lock after initial registration); we will not obstruct transfers.

9.2 Pricing and renewal. The price of each domain purchase is quoted for your approval before registration. Registrations are annual, non-refundable once registered, and renew automatically if auto-renew is on; the renewal price quoted at purchase is what we bill on renewal. You can turn auto-renew off at any time from your workspace. If auto-renew is off, or renewal cannot be funded, the domain will expire per the registry's lifecycle, which can result in permanent loss of the domain.

9.3 Connected domains. For domains you register elsewhere and connect, you are responsible for your registrar relationship and DNS; we provision hosting and certificates for the hostname you point at us.

10. Fees, wallet, and billing

10.1 Prepaid work. Sumchat has no mandatory subscription, seat fee, or brand fee. Paid work uses a personal or workspace prepaid balance. The current standard work rate is twice the provider cost used by our meters, including AI processing and hosted computer time. A specific feature or resource quote states any different price. Usage is metered as work happens; estimates are not a promise of a fixed final cost. Your billing page shows charges, funds held for admitted work, and amounts owed. We give advance notice of fee increases as required by law and at least 7 days before an increase to your current prices takes effect.

10.2 Funding and spending controls. Personal conversations use the authorized personal funding arrangement; workspace group work uses the workspace's shared balance. Owners control shared funding and allocations. Admission to paid work requires sufficient available funds. Already-admitted work can finish above its initial hold and create an amount owed; the next credit repays that amount first. Daily spending limits prevent new paid work or paid steps once reached, but do not retroactively cancel work already admitted or its charges. You can manage funds and daily limits on your billing page.

10.3 Purchased and promotional credit. You may prepay additional funds ("top-ups"). Purchased top-ups do not expire. Promotional credits are not purchased funds: they expire as disclosed when granted, have no cash value, and are not refundable. Funds are usable only for the Services, are not transferable except through supported workspace allocations, and are not a deposit or stored value redeemable in cash, except that on account termination we will refund the unused balance of purchased top-ups on request made within 90 days. Contact billing@sumchat.ai.

10.4 Optional automatic reloads. A card is charged automatically for top-ups only after its owner affirmatively enables automatic reloads with the disclosed threshold and amount. You may turn them off on the billing page. Turning them off stops new reload charges; it does not reverse charges already made or cancel work already admitted. An ordinary one-time top-up does not enable automatic reloads.

10.5 Optional storage. Workspace storage is a separate monthly purchase from an eligible Sumchat balance. Before purchase, the owner receives the amount due now, monthly price, funding source, and how to stop renewal, and must approve that quote. Storage renews monthly from the chosen balance until renewal is stopped. Stopping takes effect at the end of the paid period; added capacity is prorated, and reductions take effect at renewal. If funds cannot cover renewal, new uploads pause while retained files remain available, subject to the retention and termination rules below. Joining a workspace does not itself charge a teammate for its storage. Any refund right or guarantee already granted for an Aurasaur purchase is preserved; migration does not restart its original period.

10.6 Taxes. Fees exclude taxes; you are responsible for applicable sales, use, and similar taxes, which we collect where required.

10.7 Nonpayment. If we cannot collect amounts due, we may downgrade, suspend, or terminate the workspace after notice and a reasonable opportunity to update payment, subject to Section 13's data-export commitments.

11. Privacy and data protection

11.1 Roles. Our Privacy Policy describes how we handle personal information. For personal information in Customer Content, including your end users' data on your published sites; we act as your service provider/processor under the DPA, which is incorporated into these Terms and applies automatically.

11.2 No training on your content. We do not use Customer Content, including your conversations with Agents, your call audio and transcripts, your sites' end-user data, or your files; to train machine-learning models, and we contractually require the same of the model providers we use to run the Services.

11.3 Security. We maintain the technical and organizational measures described in the DPA, including tenant isolation, encryption in transit and at rest, and least-privilege credential custody. We will notify you of a security breach affecting your data as required by law and the DPA, and in any event within the time California law allows.

12. Suspension

We may suspend some or all of the Services for a workspace (or unpublish a specific site, or disable a specific feature or Agent capability; we use the narrowest effective remedy) if: (a) required by law or a governmental order; (b) there is a security incident or a genuine risk to the Services, other customers, or third parties; (c) the workspace materially violates these Terms or the AUP; or (d) amounts due remain unpaid after notice. Except where law or urgent risk prevents it, we will notify you and give you a chance to cure before or promptly after suspending. We restore service promptly once the ground for suspension is resolved.

13. Term; termination; data export

13.1 Term. These Terms apply from your first use of the Services until your workspace is terminated.

13.2 Termination by you. You may stop using Sumchat, turn off automatic reloads, stop storage renewal, and request deletion of your account or workspace at any time.

13.3 Termination by us. We may terminate your workspace: (a) for material breach uncured 14 days after notice; (b) immediately for serious AUP violations (such as illegal content, CSAM, malware, or fraud), repeat infringement, or legal necessity; or (c) for any reason on 30 days' notice, in which case we will refund any prepaid fees for the unexpired period and unused purchased top-ups.

13.4 Export and deletion. For 30 days after termination (except termination under Section 13.3(b) where law prohibits, or deletion you request sooner), we will make Customer Content available for export in reasonable formats, including your files, site source and data, and records of your workspace. After that window we delete Customer Content from live systems and let backups age out on our standard cycles. Domains you registered remain yours; see Section 9 for transfer and expiry.

13.5 Survival. Sections that by their nature should survive (including 4, 10 (amounts due), 14–18, and 19) survive termination.

14. Warranties and disclaimers

14.1 Our commitment. We will provide the Services with reasonable skill and care.

14.2 Disclaimer. EXCEPT AS EXPRESSLY STATED IN THESE TERMS, THE SERVICES AND ALL OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, KAITLIAN DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR TRADE USAGE. WITHOUT LIMITING THE FOREGOING, KAITLIAN DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED OR ERROR-FREE, THAT AI OUTPUT WILL BE ACCURATE, ORIGINAL, NON-INFRINGING, UNIQUE, OR ELIGIBLE FOR INTELLECTUAL-PROPERTY PROTECTION, OR THAT ANY SITE, DOCUMENT, OR REPORT PRODUCED BY THE SERVICES SATISFIES ANY LAW. AI OUTPUT CAN BE WRONG; YOU ARE RESPONSIBLE FOR REVIEWING IT BEFORE RELYING ON IT OR PUBLISHING IT. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS, SO PARTS OF THIS SECTION MAY NOT APPLY TO YOU.

15. Indemnification

You will defend, indemnify, and hold harmless Sumchat and its member, managers, employees, and agents from and against any third-party claim, demand, or proceeding, including claims by your members, your clients, and the visitors and end users of your published sites, and including government investigations; arising out of or relating to: (a) Customer Content or your published sites; (b) your use of the Services in violation of these Terms, the AUP, or law (including communications sent without required consent); (c) your products, services, and business; or (d) your breach of your representations in these Terms; and you will pay resulting damages, penalties, settlements approved by you (not to be unreasonably withheld), and reasonable attorneys' fees. We will notify you promptly of any claim and cooperate at your expense; we may participate with our own counsel at our own cost. This Section does not apply to the extent a claim arises from our breach of these Terms, our infringement of a third party's rights through the platform software itself, or our gross negligence or willful misconduct.

16. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, GOODWILL, OR DATA (EXCEPT FOR OUR DATA-EXPORT OBLIGATIONS IN SECTION 13.4), EVEN IF ADVISED OF THE POSSIBILITY; AND (b) EACH PARTY'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS WILL NOT EXCEED THE AMOUNTS YOU PAID KAITLIAN IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY (OR $100 IF YOU HAVE PAID NOTHING). THESE LIMITS DO NOT APPLY TO: YOUR PAYMENT OBLIGATIONS; YOUR INDEMNIFICATION OBLIGATIONS; EITHER PARTY'S INFRINGEMENT OR MISAPPROPRIATION OF THE OTHER'S INTELLECTUAL PROPERTY; A PARTY'S GROSS NEGLIGENCE, FRAUD, OR WILLFUL MISCONDUCT; OR LIABILITY THAT CANNOT BE LIMITED BY LAW. THE PARTIES AGREE THESE ALLOCATIONS ARE A REASONABLE BASIS OF THE BARGAIN, AND THAT THEY APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

17. Dispute resolution; arbitration; class waiver

Summary: we each agree to try to work it out informally first; if that fails, disputes are resolved by binding individual arbitration, not in court, except small-claims matters and injunctive relief for IP misuse. Neither of us can bring or join a class action. You can opt out of arbitration within 30 days.

17.1 Informal resolution first. Before filing any claim, the party with the dispute must send the other a written notice describing it (to legal@sumchat.ai, or to the account or workspace owner's verified contact details), and the parties must try in good faith to resolve it for 60 days, including at least one telephone or video conference if either party requests one. Completing this process is a condition precedent to arbitration or suit, and any statute of limitations is tolled while it runs.

17.2 Arbitration. Except as provided in Section 17.4, any dispute arising out of or relating to these Terms or the Services will be finally resolved by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules and, where applicable, its Consumer Arbitration Rules and mass-arbitration supplementary rules. The Federal Arbitration Act governs this Section. The arbitration will be held in Sacramento County, California, or (for consumers) the county where you reside, or by video at either party's election; the arbitrator may award the same individual relief a court could. Each party bears its own attorneys' fees except where law provides otherwise; arbitration fees are allocated per AAA rules, and for individual customers we will pay filing and arbitrator fees the AAA consumer rules assign to the business.

17.3 Class waiver. ALL DISPUTES MUST BE BROUGHT IN THE PARTIES' INDIVIDUAL CAPACITIES, NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims or preside over any representative proceeding. If this waiver is held unenforceable as to a particular claim, that claim (and only that claim) must proceed in court under Section 17.6. This Section does not waive claims for public injunctive relief where such a waiver is prohibited by California law; any such claim will be stayed pending arbitration of all arbitrable claims.

17.4 Carve-outs. Either party may (a) bring an individual claim in small-claims court; and (b) seek temporary injunctive relief in court to stop infringement or misuse of intellectual property or unauthorized access to the Services, without first arbitrating.

17.5 Coordinated filings. If 25 or more demands for arbitration are filed against either party with the assistance of the same or coordinated counsel or organizations raising similar claims, the parties agree the AAA's mass-arbitration supplementary rules apply, and additionally: the demands will be resolved in staged batches of up to 50; a process arbitrator will be appointed to resolve procedural disputes; after each stage the parties will participate in a global mediation session; statutes of limitations are tolled from the first filing in the coordinated group until the claimant's demand is finally resolved or released from the process; and if a claimant's demand has not been assigned to a batch within 180 days of filing, that claimant may elect to proceed in court under Section 17.6. This Section is intended to be severable from Section 17.2: if it is held unenforceable, the remainder of the arbitration agreement stands.

17.6 Courts; governing law. These Terms are governed by the laws of the State of California and applicable U.S. federal law, without regard to conflict-of-laws rules. For matters not subject to arbitration, the state and federal courts located in Sacramento County, California have exclusive jurisdiction, and the parties consent to their personal jurisdiction; except that if you are an individual consumer, this Section does not deprive you of venue rights granted by the law of your state of residence.

17.7 Opt-out. You may opt out of Sections 17.2–17.5 by emailing legal@sumchat.ai within 30 days of first accepting these Terms, stating your workspace name and that you opt out of arbitration. Opting out does not affect any other section.

17.8 Jury waiver. To the extent a dispute proceeds in court, both parties waive trial by jury to the fullest extent permitted by law.

18. Export, sanctions, and government use

You represent that you and your members are not located in an embargoed jurisdiction or on any U.S. government restricted-party list, and you will not use or export the Services in violation of U.S. export-control or sanctions law. The Services are commercial computer software; government users receive only the rights granted to all customers under these Terms.

19. General

19.1 Changes to these Terms. We may update these Terms. For material changes we will give you at least 14 days' advance notice (to account or workspace owners through verified contact details and/or in-product), and the change will apply from the stated effective date; your continued use after that date is acceptance. Changes do not apply retroactively to a dispute arising before the change. If you do not agree to a change, stop the affected service before its effective date; on request we will refund unused purchased credit and prepaid fees for the affected unexpired period. Each version of these Terms carries its version number and effective date above, and prior versions are available on request at legal@sumchat.ai.

19.2 Notices. We send notices to account or workspace owners through verified contact details and/or in-product; they are effective when sent. Send legal notices to Sumchat at legal@sumchat.ai and by mail to Kaitlian LLC, 2108 N St #17084, Sacramento, CA 95816. Our registered agent for service of process in California is Northwest Registered Agent, Inc.

19.3 Early access. Features identified as beta, preview, or early access are provided as-is, may change or end at any time, may have reduced or no support, and are excluded from any commitments in Section 14.1; our total liability for them is capped at $100.

19.4 Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control (including outages of upstream infrastructure or model providers, acts of government, and natural events), except payment obligations.

19.5 Assignment. You may not assign these Terms without our written consent, except to a successor of substantially all your assets that agrees in writing to be bound. We may assign these Terms in connection with a merger, acquisition, or sale of assets with notice to you.

19.6 Relationship; no third-party beneficiaries. The parties are independent contractors. These Terms create no third-party beneficiary rights, including in your members, clients, or end users.

19.7 Entire agreement; severability; waiver; interpretation. These Terms (with the documents they incorporate and your accepted purchase selections) are the entire agreement about the Services and supersede prior agreements on that subject. If a provision is held unenforceable, it is limited to the minimum extent necessary and the rest remains in effect. A failure to enforce is not a waiver. "Including" means "including without limitation."

19.8 Consumer rights preserved. Nothing in these Terms limits rights you have under law that cannot be limited by contract, including, for California consumers, the right under Civil Code § 1670.8 to make any statement about us (nothing in these Terms restricts reviews or criticism), and any non-waivable warranty or remedy.

Kaitlian LLC is not a law firm. Nothing in the Services or on our sites is legal advice.
