Terms of Service

1. Agreement to These Terms

Syndai is operated by Eternex, Inc., a Delaware corporation doing business as Syndai (“Eternex,” “Syndai,” “we,” or “us”), located at 2261 Market Street STE 24499, San Francisco, CA 94114. By creating an account, using the Syndai website, application, or API, or clicking to accept, you agree to these Terms and to our Privacy Policy. If you use Syndai on behalf of an organization, you represent that you have authority to bind it. You must be at least 18 and able to form a binding contract.

If you or your organization has signed a separate Master Services Agreement or other negotiated written agreement with Eternex covering the Service, that agreement governs to the extent it conflicts with these Terms; these Terms fill any gaps it does not address.

2. The Service

Syndai builds and changes websites and web apps from a plain description of what you want. You describe the site, app, or change, and Syndai designs it, writes the code in an isolated environment, and runs checks on it, such as tests, a security scan, and a browser check. For projects that Syndai hosts, a change goes live automatically once its checks pass, and you can undo any change. For a GitHub repository you connect, Syndai opens a pull request with evidence of what was done, such as test output and screenshots, and merges it only when your settings for that repository allow. You may connect repositories and, where you enable them, other accounts and sources (for example, social, email, or analytics accounts). By connecting an account you expressly authorize Syndai to act on it on your behalf, only within the scope you enable and only to perform the work you direct. That authorization is revocable at any time by disconnecting the account, and we do not delegate it to any third party. The Service also includes the API (coding-as-a-service) via scoped API keys, and a customer portal for managing runs, connected accounts, keys, credits, billing, and team access. We continuously improve the Service and may add, change, or remove features; if a change materially reduces core paid functionality, we will use reasonable efforts to give advance notice.

3. Accounts and API Keys

You are responsible for your account and everything that happens under it. Keep credentials, API keys, and connected-repository tokens confidential, and grant keys the narrowest scopes that do the job. Notify us promptly if you believe your account or a key has been compromised; we may rotate or revoke keys we reasonably believe are compromised. You are responsible for the actions of anyone you allow to use your account or keys, and your account information, particularly billing contacts, must be accurate and current.

4. Your Content and Output Ownership

Your content stays yours: you retain all right, title, and interest in the repositories, accounts, and other sources you connect and content you submit (“Customer Content”), and we claim no ownership of it. Generated output is yours too: as between you and Eternex, you own the code, pull requests, posts, media, and other output the Service generates for you, and to the extent Eternex holds any rights in that output, Eternex assigns them to you.

You grant Eternex a limited, non-exclusive, worldwide license to access, host, reproduce, and process Customer Content solely to provide, secure, and support the Service for you: for example, cloning your repository into a sandbox to build and test a change, or acting on a connected account to do the go-to-market or operations work you direct.

Adoption check: when Syndai delivers a change as a pull request, for 30 days afterward we may check your connected repository’s default branch to see whether the delivered commits landed there outside that pull request (for example, by cherry-pick or rebase). The check compares commit fingerprints (git patch-ids) using the repository access you already granted, reads no repository you have not connected, and stops when you disconnect the repository. A person at Syndai reviews any match before it is recorded; a confirmed match marks the delivery as accepted on its delivery record. Nothing is billed on acceptance, and changes Syndai itself lands (for example, under auto-merge) never count.

Where we process personal data on your behalf, our Data Processing Addendum (syndai.ai/legal/dpa) applies and forms part of these Terms. We do not use Customer Content or output to train machine-learning models, and we contractually require the LLM providers that execute your requests not to train on it either. You represent that you have the rights needed to connect the repositories, accounts, and sources you connect and to submit the content you submit, and that doing so, and the work you direct through the Service, does not violate any law or third-party right.

5. AI-Generated Output

Syndai uses large language models to plan and produce the work: code, documentation, posts, media, outreach, and other output. AI output can be wrong, insecure, incomplete, off-brand, or unsuited to your context even when it looks confident and ships with passing checks. Output is provided as-is: the evidence we attach is an aid to review, not a substitute for it. Checks are not a guarantee. For projects Syndai hosts, a change goes live automatically once its checks pass, and you can undo it. For a repository you connect, Syndai merges only when your settings for that repository allow. Checks can miss problems, so you should review the result, and you are solely responsible for the consequences of using, deploying, publishing, or sending output. You are also responsible for the lawfulness of anything you approve for publication and any outreach you direct through the Service: having a lawful basis to contact recipients and complying with the terms of the accounts you connect and with applicable law, for example CAN-SPAM, GDPR and e-privacy rules, and CASL for marketing or outreach (accurate sender identification, a working opt-out, a valid postal address, and consent or another lawful basis where required). As between you and us, you act as the sender, and as the data controller for the people you contact; Syndai is the tool you direct. Output may be similar to output generated for other customers; the ownership assignment in the previous section applies only as between you and us and does not restrict other customers' independent output. You may not represent that output was authored or endorsed by Eternex.

6. Acceptable Use

Use the Service lawfully and don’t wreck it for anyone else. You must not use the Service for any illegal purpose or to build or distribute malware or exploits; abuse the sandboxes (including cryptomining, attacking or scanning third parties, attempting to escape sandbox isolation, or running workloads unrelated to the purpose of the Service); use the Service to send unlawful, deceptive, or unsolicited bulk messages (spam), or to publish or send anything in violation of the terms of the accounts you connect or of applicable anti-spam, marketing, or e-privacy law; attempt to access or extract another customer’s data, repositories, connected accounts, prompts, or output, or any non-public part of our systems; circumvent usage limits, credit accounting, or scopes; resell or white-label the Service without a written agreement permitting it; reverse engineer the Service except as applicable law permits; or use the Service to infringe anyone’s rights. You must also comply with our Acceptable Use Policy at /legal/acceptable-use, including the usage policies of the AI providers that power the Service (currently Anthropic, OpenAI, and Google). In particular, you must not use the Service or its Output to build, train, or improve a competing AI or foundation model, to extract or resell raw or standalone access to the underlying models, or for any use those AI providers prohibit. That policy forms part of these Terms, and breaking it breaks these Terms. We may throttle, suspend, or terminate access that we reasonably believe violates this section or that policy.

7. Fees, Credits, and Billing

Paid plans and credit packs are offered through the Service. New accounts receive a one-time grant of free credits to start; once it is used, further usage requires a paid plan or credit pack. Nothing here obligates us to keep offering any particular plan. Most usage consumes credits metered against the work performed, and a run consumes credits for the compute it uses even if it does not produce a usable result, with one exception: if a run fails because of a problem on our side (for example our infrastructure, the run's sandbox, an upstream model-provider outage, or an internal error), we automatically return the credits it used to your balance, once, as credits rather than cash. This does not apply to a run you stop, a run that reaches the spend limit you set, or a run that ends because your own code's checks fail; current pricing is published on our site or in your order form. Credits are not money, are non-transferable and, except where required by law or expressly stated otherwise, are non-refundable and expire as described at purchase. Subscription tiers renew automatically at the end of each billing period until you cancel; you can cancel any time through the portal, effective at the end of the current period, and we do not prorate partial periods except where required by law. Before each renewal we send a reminder to your account email that names the plan, the amount and frequency of the charge, and how to cancel, and for any term of a year or longer we send that reminder between 15 and 45 days before the renewal date.

Purchases are sold and processed by Polar (polar.sh), which acts as the merchant of record and collects applicable taxes; Polar's buyer terms also apply to your purchase, including its refund and withdrawal terms. You authorize Polar to charge your payment method for subscription fees and the credit purchases you make. We may change prices with at least 30 days’ notice, applying from your next billing period; the notice will tell you the new price, when it starts, and how to cancel if you do not want to continue. Fees are exclusive of taxes. Raise billing disputes within 60 days of the charge and we will work with you in good faith to resolve them.

Fraud prevention. To protect the Service and other customers, we may verify or preauthorize your payment method, set starting spend limits and usage caps, and pause or restrict your account right away if we reasonably suspect fraud, unauthorized card use, or a chargeback. If you dispute a charge with your bank instead of contacting us first, we may suspend paid features while we resolve it. Genuine billing disputes are still handled through the good-faith dispute process above.

Consumers in the EU and UK. If you are an individual buying for personal use in the EU or UK, you have a 14-day right to withdraw from a new subscription or credit purchase. When you start a run, generate a pull request, or otherwise use the Service within those 14 days, you are asking us to begin right away, and you agree that once we have fully performed you lose the right to withdraw. If you withdraw before we have finished, we may charge you a fair amount for what you have already used. To withdraw, cancel in the portal or email legal@syndai.ai.

8. Suspension and Termination

You may stop using the Service and cancel your account at any time through the portal where the portal offers it, or by emailing legal@syndai.ai from your account address. We may suspend or terminate your access, with notice where practicable, if you materially breach these Terms, your usage creates security, legal, or operational risk to the Service or other customers, or the law requires it; for curable breaches we will normally give you a chance to cure. To appeal a suspension, email support@syndai.ai from your account address. We may discontinue the Service or a feature with reasonable advance notice and will refund unused prepaid amounts for anything we discontinue. Upon termination, your right to use the Service ends and Customer Content is deleted or deactivated per our Privacy Policy; provisions that by their nature should survive (including ownership, disclaimers, liability limits, and indemnification) survive.

9. Our Intellectual Property

Eternex and its licensors own the Service: the software, infrastructure, documentation, design, and branding, and all intellectual property rights in them. Except for the rights expressly granted in these Terms, no rights in the Service are granted to you. Feedback you choose to give us may be used without restriction or obligation to you.

10. Disclaimer of Warranties

THE SERVICE AND ALL OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE OR THAT OUTPUT WILL BE ACCURATE, SECURE, COMPLETE, OR FIT FOR ANY PURPOSE. Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, AND ETERNEX’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE FEES YOU PAID TO ETERNEX FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. These limits apply regardless of the theory of liability and even if a limited remedy fails of its essential purpose, but do not limit liability that cannot be limited under applicable law, your payment obligations, or either party’s liability for willful misconduct.

12. Indemnification

You will defend, indemnify, and hold harmless Eternex and its officers, directors, employees, and agents from third-party claims and resulting damages, liabilities, costs, and reasonable attorneys’ fees arising out of or relating to: your Customer Content, including claims that it infringes a third party’s rights; your use of the Service or output in violation of these Terms or applicable law; or your merging, deploying, distributing, publishing, or sending output. We will promptly notify you of any such claim and reasonably cooperate at your expense; you may not settle a claim in a way that imposes obligations on us without our consent.

13. Copyright Complaints (DMCA)

If you believe content available through the Service infringes your copyright, send a notice complying with the DMCA (17 U.S.C. § 512) to: Copyright Agent, Eternex, Inc., 2261 Market Street STE 24499, San Francisco, CA 94114, or legal@syndai.ai with the subject line “DMCA Notice.” Include identification of the work and the allegedly infringing material, your contact information, a good-faith-belief statement, a statement under penalty of perjury that the notice is accurate and you are authorized to act, and your signature. We may remove material in response to valid notices and may terminate repeat infringers’ accounts.

14. Changes, Governing Law, and Contact

We may update these Terms from time to time. For minor changes we post notice in the app and update the effective date, and continued use after the effective date means you accept them. For material changes we give advance notice by email to your account address, a notice in the portal, or both, and ask you to accept the updated Terms before you continue using the Service; if you do not accept, you can cancel before the change takes effect and we will refund any unused prepaid amount for the period you are cutting short. Changes required by law may take effect sooner. If you are a consumer, nothing in these Terms removes rights you have under the consumer-protection laws of your country, and where a term here conflicts with those rights, those rights apply. These Terms are governed by the laws of the State of California, and any dispute will be brought exclusively in the state or federal courts located in San Francisco County, California. If a provision is unenforceable, the rest remains in effect; failure to enforce a provision is not a waiver; you may not assign these Terms without our consent except to a successor in a merger or asset sale, and we may assign them in connection with a merger, acquisition, or sale of assets. Neither party is liable for delay or failure caused by events beyond its reasonable control.
