Terms of Service
These Terms govern your use of Ultron. By creating an account or using the service in any other way, you agree to be bound by them. If you are using Ultron on behalf of an organisation, you confirm that you have authority to bind that organisation to these Terms.
Acceptance
By accessing Ultron through any interface, including the web application, the API, or the agent SDK, you agree to be bound by these Terms, the Acceptable Use Policy, the Privacy Policy, and any other document we incorporate by reference. If you do not agree, do not use the service.
If you accept these Terms on behalf of a company, you represent that you are authorised to do so, and the words you and your in this document refer to that company. The individual signing up is the named administrator of the account until the company designates another.
What Ultron is
Ultron is a software platform that lets you trigger structured AI workflows, called skills, against your own data and connected third party services. The platform composes large language models with a tool layer, a memory layer, and a sandbox layer. You direct the work through a chat surface or a programmatic interface; the platform runs it and reports back.
We may change the features, add new ones, retire ones we no longer support, or move features between plans. We will not make a material reduction in the functionality of a paid plan during a paid term without offering a prorated refund of the affected portion.
Eligibility
You may use Ultron only if you can form a binding contract under the law that applies to you. You must be at least sixteen years old. If you are based in a country subject to a comprehensive embargo by the European Union or other applicable trade restriction, you may not use the service.
You are responsible for ensuring that your use of Ultron is lawful in your country and for any industry-specific regulation that applies to your business.
Account
Registration
You create an account with accurate information and keep it accurate. You are responsible for the actions taken from your account, including by anyone you invite. Share access only with people you trust to follow these Terms.
Credentials
You keep your password, API keys, and OAuth tokens confidential. Notify us at security@51ultron.com if you suspect unauthorised access. We are not liable for losses that result from your failure to safeguard credentials.
Workspaces and seats
Paid plans are scoped to a workspace. Each seat is for one named human. You may not share a seat across multiple people or use a single account to circumvent per-seat pricing.
Plans and fees
Subscription model
Paid plans are billed in advance on a monthly or annual cycle. Subscriptions renew automatically at the end of each cycle at the then-current price for your plan unless you cancel before the renewal date. Prices may change at renewal; we give you at least thirty days notice before a price increase takes effect.
Usage and overages
Some plan limits are soft. Going over a soft limit triggers metered pricing as published on the pricing page. We notify you when you approach an overage threshold. Hard limits are enforced at the API layer and surface as a denied request.
Taxes
Prices are exclusive of value added tax and any other applicable taxes. Where required by law we collect VAT at the rate of the customer's country and remit it to the appropriate authority.
Payment and failure
You authorise us to charge the payment method on file for all amounts due. If a payment fails, we retry on a published schedule and notify you. Persistent non-payment results in suspension and, if not cured, termination of the account.
Your content
You keep all rights to the content you upload, store, generate, or otherwise process through Ultron, including text, files, images, leads, and any data sourced from third party systems you connect. We do not claim ownership.
You grant us a worldwide, non-exclusive, royalty-free licence to host, copy, transmit, and display your content solely as required to deliver the service to you, to make the content available through your connected integrations at your direction, to back it up, and to enforce these Terms. The licence ends when you delete the content, except for backup copies retained for the retention windows described in the Privacy Policy.
We do not use your content, prompts, or outputs to train foundation models. We do not allow our model providers to train on your content either. See the Data Processing Addendum and the Subprocessors page for the contractual basis of this commitment.
Our content
The Ultron platform, including software, design, documentation, brand assets, and the skill templates we publish, is our intellectual property or that of our licensors. We grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the platform for the duration of your subscription, for the purposes contemplated by these Terms.
You may not copy, modify, decompile, or reverse engineer the platform, except to the extent the law expressly permits. You may not scrape the service, train competing models on its surface, or rebrand the service as your own without a separate written agreement.
Feedback
If you send us feedback, ideas, bug reports, or suggestions, you grant us a perpetual, irrevocable, royalty-free licence to use that feedback to improve the service. You waive any moral rights in feedback to the extent permitted by law.
AI outputs
Ultron produces outputs generated by AI models. To the extent we own any rights in those outputs, we assign them to you. You are responsible for reviewing the output before relying on it, for verifying factual claims, and for ensuring that the output is not misleading, harmful, or unlawful in your context. The AI output disclaimer page details what outputs are and what they are not.
The same prompt can generate similar outputs for different users. You acknowledge that outputs of a generative model are not unique and that we may produce similar or identical outputs for others.
Conduct
Use of the service is subject to the Acceptable Use Policy, which is incorporated into these Terms. A violation of the AUP is a violation of these Terms. The AUP catalogues prohibited behaviours, including unlawful use, abuse of the AI surface, infrastructure abuse, and attempts to deceive the platform's safety mechanisms.
Third party services
Ultron integrates with services run by third parties, including model providers, email providers, payment processors, scrapers, and analytics tools. Your use of a third party service through Ultron remains subject to the third party's own terms. We are not responsible for the acts, omissions, or content of third party services, and we cannot guarantee their availability.
We may stop integrating with a third party at any time. When that happens, we will give you reasonable notice if the integration is material to your usage, and we will help you export the data we hold on your behalf.
Suspension and termination
By you
You can cancel your subscription from the billing settings at any time. Cancellation takes effect at the end of your current paid term. You can delete your account at the same time, in which case your content is removed in accordance with the Privacy Policy.
By us
We may suspend or terminate an account if you breach these Terms or the AUP, if continued service would expose us or third parties to material legal risk, or if required by court order. Where the breach is curable, we give notice and a reasonable opportunity to cure first. Termination for cause does not entitle you to a refund of fees already paid.
Survival
The clauses on ownership, AI outputs, indemnity, disclaimers, limitation of liability, governing law, and miscellaneous survive termination.
Disclaimers
To the maximum extent permitted by law, the service is provided on an as-is and as-available basis without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or that outputs will be accurate, complete, or fit for any specific purpose.
Mandatory consumer protection rules in your country of residence override anything in this clause that conflicts with them.
Limitation of liability
To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential, or exemplary damages, including lost profits, lost revenue, lost data, business interruption, or cost of substitute services, even if advised of the possibility.
Our total aggregate liability arising out of or related to these Terms or the service, in contract, tort, or any other theory, is capped at the greater of one hundred euros or the amount you paid us in the twelve months immediately preceding the event giving rise to the claim.
This clause does not limit liability for death or personal injury caused by negligence, for fraud, for wilful misconduct, or for any other liability that cannot be limited by law. Mandatory consumer rules in your country take precedence over this clause.
Indemnity
You will defend, indemnify, and hold us harmless from any claim by a third party arising out of your content, your violation of these Terms or the AUP, or your violation of a third party's rights. We give you prompt notice of any claim, let you control the defence with counsel of your choosing, and cooperate in the defence at your expense. You may not settle a claim that imposes obligations or admissions on us without our written consent.
Modifications
We may revise these Terms. Material changes that affect your rights or obligations are announced at least thirty days before they take effect, with notice to the email on your account and a banner inside the product. Continued use after the effective date means you accept the revised Terms. If you do not accept, you can cancel before the effective date.
Governing law and venue
These Terms are governed by the law of Romania, without giving effect to choice-of-law rules. The courts of Bucharest have exclusive jurisdiction over disputes, except that consumer disputes may be brought in the courts of the consumer's country of residence as required by mandatory EU consumer law.
European consumers may also access the Online Dispute Resolution platform run by the European Commission at ec.europa.eu/consumers/odr.
Miscellaneous
Assignment
You may not assign these Terms without our prior written consent. We may assign them in connection with a merger, acquisition, or sale of assets.
Force majeure
Neither party is liable for a failure to perform caused by an event outside its reasonable control, including natural disasters, war, terrorism, cyber attacks against shared infrastructure, or the failure of a major upstream provider, provided the affected party gives prompt notice and uses reasonable efforts to mitigate.
Severability
If any provision of these Terms is held unenforceable, it is severed and the remaining provisions stay in effect.
Entire agreement
These Terms, together with the documents they reference, are the entire agreement between you and us. They supersede any prior agreement on the same subject matter.
