Terms of Service

1. The agreement

These terms are a contract between you and VectorBrain("VectorBrain", "we", "us") governing your use of the VectorBrain application and website at vectorbrain.one (the "Service"). By creating an account or using the Service you accept these terms. If you use the Service on behalf of a company, you accept them for that company and confirm you have authority to do so.

Please read section 4 and section 5 carefully. They describe how the Service depends on an AI provider account that belongs to you, and they set out the limits of what we are able to control on your behalf.

2. Who can use the Service

You need an account to use the Service. Keep your credentials confidential; activity under your account is your responsibility. You must be at least 16 years old and provide accurate account information. Workspaces on the Team plan may include multiple member seats; the workspace administrator controls roles, access, and the shared provider key, and is responsible for the conduct of the members they invite.

3. Subscriptions, billing, and what your fee does not include

The Service is a paid subscription (Lite, Pro, or Team) billed monthly through Stripe, our payment processor. Prices are shown at checkout and on the pricing page. Plans differ by storage and seats; product features are included on all plans. Subscriptions renew automatically until cancelled. You can cancel any time from Settings; cancellation takes effect at the end of the current billing period, and already-paid fees are non-refundable except where the law requires otherwise. We may change prices with at least 30 days' notice; changes apply from your next renewal.

Your subscription fee pays for the VectorBrain workspace only. It does not include the cost of AI usage. AI models are paid for separately by you, directly to your AI provider, at that provider's prices. We add no markup and take no share of it. If you stop paying your provider, or your provider credits run out, AI features will stop working even though your VectorBrain subscription is still active. That is not a fault in the Service and does not entitle you to a refund.

4. Your own AI provider key (BYOK)

The Service runs on an API key that you bring from a third-party AI provider, ordinarily OpenRouter. This is a deliberate design choice: it keeps your AI usage at cost and under your control. It also means a second company is involved in every AI request, and you should understand that relationship.

• You contract directly with the provider. Your agreement with OpenRouter (and with the model providers behind it) is between you and them. We are not a party to it, cannot negotiate it, and cannot act on your behalf under it. Their terms of service and privacy policy apply to you directly.
• You pay them, not us. AI usage is billed by the provider to your account, on their payment terms — including any rules they set about credits, expiry, and refunds. We never see, hold, or control those funds.
• You are responsible for the model terms. OpenRouter requires that you review the terms applicable to each model before you use it. Different models carry materially different conditions, including on data use and on ownership of output.
• Spending limits are yours to set. Any cap on AI spend lives on your provider account. We recommend setting one. We cannot impose or enforce a limit on your provider account.
• How we handle your key. We store it envelope-encrypted at rest, use it only to perform work you ask for, never write it to logs, and never display it again after you enter it. You can replace or remove it at any time.

5. What we control, and what we do not

We think you are entitled to a plain answer about where our responsibility ends. It ends at the boundary of our own systems.

We are responsible for:

• the VectorBrain workspace — your projects, documents, media, and settings, and keeping them available to you;
• keeping every workspace isolated, so one customer's data is never reachable from another's;
• encrypting your provider key at rest and not exposing it;
• sending your request to the model you selected, and to no other model;
• deleting your content from our systems when you ask, as described in our Privacy Policy;
• not using your content to train AI models, ever.

We are not able to control:

• What a model provider does with your prompt.Once a request leaves our systems for your provider, that provider's policies govern it — including whether they retain it, for how long, and whether they may use it to train or improve their models.
• Which upstream provider serves your request. You choose a model in VectorBrain; OpenRouter decides which of its upstream providers actually serves that model, according to its own routing. That routing is theirs, not ours.
• Provider pricing, availability, or uptime. Models are added, repriced, deprecated, and withdrawn by their providers without reference to us. A model you rely on may become more expensive or disappear.
• Your provider account. If your provider suspends, rate-limits, or closes your account, or applies geographic restrictions, we cannot reverse it.
• Whether AI output is accurate. See section 9.

We do not accept liability for any of the matters in the second list. Where we can reduce the risk for you — by showing real prices, letting you switch models freely, and never locking your work to one provider — we do.

6. Model choice and training on your prompts

This is the single most important thing to understand about running AI on your own key, and it is genuinely in your hands rather than ours.

The controls exist, and they live in your provider account. OpenRouter provides account-level settings governing whether your requests may be routed to providers that train on your data, with separate toggles for paid and for free models. You can set these here:

• Your OpenRouter privacy settings — the account toggles themselves.
• OpenRouter: privacy, logging, and provider data policies — how the toggles work and how each provider's policy is shown.
• The OpenRouter model directory — the models and providers available to you, to review before you commit work to one.

Because these settings sit on your account rather than ours, we cannot set them for you, cannot verify what you have chosen, and cannot override a provider's policy. Note also that OpenRouter states these toggles govern routing to providers and do not alter OpenRouter's own handling of your prompts, which its privacy policy covers separately. You are responsible for choosing models whose data policies you find acceptable, and for reviewing them again if your requirements change.

7. Information you must not put into the Service

The Service is a workspace for building and running a business. It is not built, certified, or audited to hold regulated financial, payment, or health data, and anything you enter may be transmitted to a third-party AI provider under section 5.

Your legitimate business content — plans, drafts, brand material, customer notes, financial figures in the ordinary sense of revenue and costs — is exactly what the Service is for, and section 8 governs it. This section is about the narrow category of credentials and regulated identifiers that should not be pasted into any AI tool, ours included.

If you upload information covered by this section, you do so at your own risk, and we are not liable for the consequences. If you become aware that you have, remove it and rotate any exposed credential immediately, then contact us at hello@vectorbrain.one so we can assist with deletion.

Where you upload personal data about other people, you are responsible for having a lawful basis to do so and for meeting your own obligations to them as a data controller.

8. Your content and your business information

Everything you create or upload in the Service — projects, documents, media, wiki entries, skills, prompts, and business records — remains yours. We claim no ownership of it and no ownership of AI-assisted work you produce with it.

You grant us only the narrow, revocable licence technically necessary to operate the Service for you: to store your content, transmit it to the AI provider you have chosen when you ask us to run a task, process it to render the product, and back it up. That licence exists to run the product and for nothing else, and it ends when you delete the content or close your account.

We do not read, mine, analyse, sell, share, or otherwise make use of your business information for any purpose of our own. We do not use it to train AI models, ours or anyone else's. We do not use it to build datasets, benchmarks, or product features. We do not use it for advertising or profiling, and we do not sell or rent it to anyone. Your files and the storage they occupy are yours; we treat them as material we are holding on your behalf, not as an asset of ours.

The only circumstances in which our staff access workspace content are: where you explicitly ask us to, in order to resolve a support issue; where it is strictly necessary to investigate a security incident or suspected breach of section 10; or where we are legally compelled. Any such access is limited to what the task requires. Diagnostic and error reporting is covered in our Privacy Policy and is deliberately scoped to operational data rather than the substance of your work.

You are responsible for having the rights to the content you upload.

9. AI output and your duty to verify

AI models generate text by prediction, not by looking up verified facts. They can state something false with complete confidence, invent citations, misstate figures, and produce code with defects. This is an inherent property of the technology and not a malfunction of the Service.

Output is provided for your review. You are responsible for checking it before you rely on it, publish it, send it to a customer, or act on it commercially. Nothing produced through the Service is legal, financial, tax, medical, or other professional advice, and it must not be treated as a substitute for a qualified professional. We are not liable for decisions taken in reliance on AI output.

Ownership of AI output can also depend on the terms of the specific model that generated it, which is a further reason to review the model terms referenced in section 4.

10. Acceptable use

You agree not to use the Service to:

• break the law or infringe the rights of others;
• generate or distribute malware, spam, or deceptive content presented as human-made where that misleads materially;
• produce content that sexualises minors, incites violence, or harasses a person;
• attempt to breach workspace isolation, probe the Service's security, circumvent usage limits, or access another customer's data;
• breach the terms of any AI provider whose models you reach through the Service, including their restrictions on permitted use;
• resell or white-label the Service without our written agreement.

We may suspend or terminate accounts that violate these rules, with notice where practical and immediately where the violation is severe or ongoing.

11. Service changes and availability

We improve the Service continuously and may add, change, or retire features. We aim for high availability but do not promise uninterrupted service, and we depend on infrastructure and AI providers whose outages are outside our control. If we ever discontinue the Service, we will give you reasonable notice and a way to export your content.

12. Disclaimers

To the fullest extent the law allows, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, that AI output will be accurate or suitable for any purpose, or that any third-party provider will continue to make any model available.

13. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential, or punitive damages, nor for lost profits, lost revenue, lost data, or business interruption, arising from or relating to the Service.

We are not liable for: the acts, omissions, policies, pricing, or availability of any AI provider or model provider; a provider's use of your inputs or outputs, including for training; charges incurred on your provider account; decisions made in reliance on AI output; or your failure to observe section 7.

Our total aggregate liability for all claims arising in any twelve month period is capped at the total subscription fees you paid us in the twelve months before the claim arose. Because we take no share of your AI spend, AI usage charges are not part of that calculation. Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including for death or personal injury caused by negligence, or for fraud.

14. Indemnity

You agree to indemnify and hold us harmless from claims, damages, losses, and reasonable legal costs arising from your content, your use of the Service in breach of these terms, your breach of any AI provider's terms, your infringement of a third party's rights, or your upload of information prohibited by section 7.

15. Termination

You can stop using the Service and cancel at any time. We may suspend or terminate your access for material breach of these terms. After cancellation or termination your workspace data is retained for 30 days so you can export it or reactivate, then deleted from active systems in the ordinary course. Sections 8, 9, 12, 13, and 14 survive termination.

16. Governing law and disputes

These terms are governed by [governing law and courts], and the courts of that jurisdiction have exclusive jurisdiction over any dispute, except that if you are a consumer you retain the benefit of any mandatory protections and any right to bring proceedings in the courts of your own country of residence where the law gives you that right.

Before starting formal proceedings, please contact us at hello@vectorbrain.one; most disputes can be resolved quickly and directly.

17. Changes to these terms

We may update these terms as the Service evolves. For material changes we will notify you (for example by email or in-app) at least 14 days before they take effect. Continuing to use the Service after that means you accept the updated terms. If you do not accept them, you may cancel before they take effect.
