We are based in the United Kingdom and make the service available internationally. Availability of the service in a particular country does not mean that we market it there, nor that it complies with local requirements in that country — see section 20.
These terms and your agreement
These terms apply to (a) visitors to quaestra.ai and its subdomains, and (b) organisations and individuals who access the Quaestra.ai service, whether on a free, trial, or paid basis.
By accessing the website or using the service, you confirm that you accept these terms. If you do not accept them, you must not use the website or the service.
If you use the service through an organisation that has its own agreement with us (an order form, subscription agreement, or enterprise contract), that agreement takes precedence over these terms where they conflict. If you use the service as a member of an organisation’s workspace, your organisation — not Quaestra — controls your account, the documents in that workspace, and the settings applied to it.
If you accept these terms on behalf of an organisation, you confirm that you have authority to bind that organisation.
Definitions
- Service — the Quaestra.ai hosted research platform, including workspaces, administrative consoles, integrations, and any documentation and support we provide.
- Workspace — an isolated organisation environment within the service.
- Customer Content — documents, corpora, frameworks, questions, prompts, attachments, configuration, and any other material you or your users submit to the service.
- Output — answers, summaries, citations, exports, and other material the service generates in response to Customer Content and your instructions.
- Administrator — a user with permission to manage a workspace, its members, its library, or its settings.
Eligibility and accounts
You must be at least 18 years old to use the service. The service is designed for professional and organisational use and is not directed at children.
You must provide accurate registration information and keep it up to date. Sign-in may use one-time email codes or single sign-on where your organisation has enabled it.
You are responsible for activity that takes place under your account and for keeping your sign-in method, access codes, and any API or integration keys secure. Tell us at info@quaestra.ai promptly if you believe your account has been compromised.
Accounts are for named individuals. Do not share an account, and do not let anyone else use your credentials.
The service and access to it
Subject to these terms, we grant you a non-exclusive, non-transferable, revocable right to access and use the service for your internal business or professional purposes during your subscription or trial period.
Some features depend on your plan, on your organisation’s configuration, or on entitlements enabled by an Administrator. Free tiers, trials, and evaluation access may be subject to usage quotas, feature limits, or time limits, and may be modified or withdrawn.
We may apply fair-use limits — for example on questions per day, storage, document volume, or automated requests — to protect service quality for all customers.
Your content and your corpus
You own your content. As between you and Quaestra, you retain all rights in Customer Content. We claim no ownership of it.
You grant us a limited, worldwide, royalty-free licence to host, store, copy, transmit, index, and process Customer Content solely to provide, secure, and support the service for you, and as otherwise permitted in writing by you. This licence ends when the content is deleted, except for copies retained in routine backups for a limited period.
We do not use your content to train models. Customer Content is not used to train, fine-tune, or improve any machine-learning model — ours or anyone else’s.
You are responsible for Customer Content, including for having the necessary rights, licences, and permissions to upload it and to have it processed by the service. Do not upload material you are not permitted to copy, share, or process — including third-party material where a licence or publisher agreement prohibits it.
As between you and Quaestra, you may use Outputs for your own purposes. Outputs are generated from your material and are not unique to you: similar questions may produce similar answers for others. We make no claim of ownership over Outputs, and we make no representation that Outputs are free of third-party rights.
Where the service connects to an external source you nominate — such as a cloud drive — it reads from that source only. It does not modify, move, or delete files in the source system.
Acceptable use
You must not, and must not permit anyone else to:
- use the service unlawfully, fraudulently, or for any harmful, deceptive, or infringing purpose;
- upload content that is unlawful, defamatory, obscene, or that infringes anyone’s intellectual property, privacy, or confidentiality rights;
- upload special category personal data, health records, payment card data, or government identifiers unless we have agreed in writing that your configuration is suitable for it;
- attempt to circumvent access controls, usage quotas, tenant boundaries, or security measures, or access another organisation’s workspace or data;
- reverse engineer, decompile, or attempt to derive the source code, models, prompts, or underlying methods of the service, except to the extent that restriction is prohibited by law;
- copy, resell, sublicense, or make the service available to third parties as a competing or derivative offering, or use it to build a competing product;
- scrape, crawl, or bulk-extract the service or its Outputs other than through features and interfaces we provide for that purpose;
- introduce malware, or interfere with or place unreasonable load on the service or its infrastructure;
- use Outputs in a way that misrepresents them as human-authored where that would mislead, or present them as professional advice from Quaestra;
- use the service to generate content that harasses, discriminates against, or endangers others, or that is intended to deceive.
We may investigate suspected breaches and take proportionate action, including removing content, restricting a feature, or suspending access under section 12.
AI-generated outputs
The service uses language models as a tool for comprehension and drafting. Answers are drawn from the corpus you curate and are presented with citations so that you can check them against the source passage.
Outputs may still be incomplete, out of date, or wrong. Citations may be mismatched, and a source document may itself be inaccurate. You must review and verify Outputs before relying on them, particularly for any decision with legal, financial, clinical, regulatory, or safety consequences.
Outputs are not professional advice. Quaestra does not provide investment, legal, medical, tax, or other regulated advice, and no lawyer–client, adviser–client, or clinician–patient relationship is created by your use of the service. Professional judgement remains yours.
You are responsible for any decision you take, or that you allow others to take, on the basis of an Output.
Third-party services and models
The service is model-agnostic and relies on third-party providers for model inference, hosting, email delivery, payment processing, and similar functions. Where your organisation supplies its own provider keys, or connects its own external sources or tools, your use of those third-party services is governed by your agreement with that provider, and their availability, pricing, and terms are outside our control.
We are not responsible for third-party services, content, or websites we link to. Where a provider changes or withdraws a model or feature, we may need to substitute an equivalent.
Our intellectual property
The service, the website, and all software, design, text, graphics, and documentation within them (excluding Customer Content) are owned by Quaestra or our licensors and are protected by intellectual property laws. Except for the limited rights expressly granted in these terms, no rights are transferred to you.
“Quaestra” and “Quaestra.ai”, together with our logos, are our trade marks. You may not use them without our prior written consent.
If you send us feedback, suggestions, or feature requests, we may use them without restriction and without obligation to you. Feedback should not contain your confidential information.
Fees, billing and taxes
Paid plans are billed in advance at the price and frequency shown at the point of purchase or in your order form. Unless stated otherwise, subscriptions renew automatically for successive periods until cancelled.
Payments are handled by our payment provider. We do not store your full payment card details. You must give accurate billing information and keep it current.
Prices exclude VAT and other applicable taxes unless stated. Where we are required to charge VAT or another tax, it will be added. Where you are required to withhold tax, the amount payable to us will be grossed up so that we receive the full amount invoiced.
We may change prices for a renewal period by giving you reasonable notice before that period begins. If you do not accept a price change, you may cancel before the renewal takes effect.
Except where required by law, or where these terms state otherwise, fees are non-refundable and there is no refund for partial periods, unused quota, or features you did not use. Cancelling stops future renewals; it does not refund the current period.
If a payment fails or is overdue, we may suspend access until the balance is settled and may charge statutory interest on late payment where you are a business customer.
Term, suspension and termination
These terms apply from the moment you first use the website or the service and continue until your account or subscription ends.
Your right to end. You may cancel a subscription or delete your account at any time using the controls in the product, or by contacting us. Where you are part of an organisation’s workspace, your Administrator manages your access.
Our right to suspend. We may suspend access, in whole or in part, where we reasonably believe there is a security risk, a breach of section 7, unlawful use, non-payment, or a legal requirement to do so. Where practicable we will give notice first and restore access once the issue is resolved.
Our right to end. We may terminate these terms on reasonable notice, or immediately if you commit a material breach that is not remedied within 14 days of us asking, or if you become insolvent.
After termination. Your right to use the service stops immediately. You should export any content you need before your account closes. We will delete or return Customer Content in accordance with our Privacy Policy and any applicable data processing agreement, subject to routine backup cycles and any legal retention obligation. Sections that by their nature should survive — including sections 6, 10, 13, 16, 17, 18, 23, and 24 — continue to apply.
Confidentiality
Each party may receive confidential information from the other. Each party will keep the other’s confidential information secret, use it only to perform its obligations or exercise its rights under these terms, and disclose it only to those who need it and who are bound by equivalent obligations.
This does not apply to information that is or becomes public through no breach, that was already lawfully known, that is independently developed, or that must be disclosed by law or a regulator — in which case the disclosing party will, where lawful, give prior notice.
Data protection
Our handling of personal data is described in the Privacy Policy, which forms part of these terms.
Where we process personal data contained in Customer Content on your behalf, you act as controller and we act as processor. A data processing agreement setting out the required terms under UK GDPR Article 28 and EU GDPR Article 28 is available on request from info@quaestra.ai.
You are responsible for having a lawful basis for the personal data you place in the service, for providing any notices and obtaining any consents required from the individuals concerned, and for responding to their requests where the data sits in your workspace. We will provide reasonable assistance.
Availability, support and changes
We aim to keep the service available and to give advance notice of planned maintenance where we can, but we do not guarantee uninterrupted or error-free operation unless a separate service level agreement says otherwise.
We may change, add to, or remove features to improve the service, to meet a legal or security requirement, or where a third-party dependency changes. We will not make a change that materially reduces the core functionality of a paid plan during a period you have already paid for without offering you a pro-rata refund for the remainder of that period if you choose to cancel.
Support is provided by email at info@quaestra.ai during UK business hours, unless your agreement provides otherwise.
Warranties and disclaimers
We warrant that we will provide the service with reasonable skill and care, and that we have the right to grant the rights set out in these terms.
Other than as expressly stated, and to the fullest extent permitted by law, the service and the website are provided “as is” and “as available”. We exclude all implied warranties, conditions, and terms, including as to satisfactory quality, fitness for a particular purpose, non-infringement, and accuracy.
In particular, we do not warrant that Outputs will be accurate, complete, current, or suitable for any purpose, or that the service will meet a specific regulatory requirement in your jurisdiction or industry. See section 8.
Limitation of liability
Subject to the paragraph above, and to the fullest extent permitted by law:
- we are not liable for loss of profits, loss of business, loss of anticipated savings, loss of goodwill, business interruption, or for any indirect or consequential loss, however arising;
- we are not liable for loss or corruption of data to the extent it could have been avoided by you keeping your own copies of Customer Content;
- we are not liable for any decision, act, or omission based on an Output, or for your failure to verify an Output;
- our total aggregate liability arising out of or in connection with these terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, is limited to the greater of (a) the total fees you paid us in the 12 months immediately before the event giving rise to the claim, and (b) £100.
Where you use the service free of charge, our total aggregate liability is limited to £100.
This section does not affect the rights of consumers described in section 19.
Indemnity
If you use the service as a business, you will indemnify us against losses, liabilities, damages, and reasonable costs (including legal fees) arising from a third-party claim that results from Customer Content, from your breach of section 7, or from your unlawful use of the service. We will notify you of any such claim, allow you to control its defence with counsel of your choosing, and give you reasonable assistance at your cost.
This section does not apply to consumers.
Consumer rights
If you use the service as a consumer — that is, wholly or mainly outside your trade, business, craft, or profession — you have statutory rights that these terms do not affect, including under the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
You normally have 14 days from purchase to cancel a subscription and receive a refund. If you ask us to start providing the service immediately during that period, you may be charged a proportionate amount for what you have used, and the right to cancel ends once the service has been fully provided.
Nothing in section 17 limits our liability to consumers for failing to perform the service with reasonable care and skill, or for foreseeable loss caused by our breach.
If you are a consumer resident in the EEA, you may bring proceedings in the courts of your country of residence, and mandatory consumer protections in that country continue to apply to you.
If you have a complaint, please write to info@quaestra.ai. We aim to acknowledge complaints within five working days.
Export controls and sanctions
The service is operated from the United Kingdom and is available internationally, but it is not offered where doing so would be unlawful. You must not access or use the service if you are located in, ordinarily resident in, or acting on behalf of a person or entity subject to UK, EU, US, or UN sanctions, or in a jurisdiction subject to comprehensive sanctions.
You are responsible for complying with the laws of the country from which you access the service, including any local restrictions on the use of artificial intelligence, data export, or the material you upload.
Changes to these terms
We may update these terms from time to time — for example to reflect a change to the service, to our providers, or to the law. The “last updated” date at the top shows when they were last changed.
Where a change is material and adverse to you, we will give reasonable notice by email or in the product before it takes effect. If you do not accept the change, you may cancel before it applies. Continuing to use the service after the effective date means you accept the updated terms.
General
Entire agreement
These terms, together with the Privacy Policy and any order form or data processing agreement between us, form the entire agreement about your use of the service and replace any earlier understanding. Neither party relies on any statement not set out in them, though nothing excludes liability for fraudulent misrepresentation.
Assignment
You may not assign or transfer your rights under these terms without our written consent. We may assign or transfer ours to a group company or in connection with a merger, acquisition, or sale of assets, provided your rights are not adversely affected.
Severance and waiver
If any provision is found to be unenforceable, the rest remains in force. A delay in enforcing a right is not a waiver of it.
Third-party rights
No one other than the parties has any right to enforce these terms under the Contracts (Rights of Third Parties) Act 1999.
Force majeure
Neither party is liable for failure or delay caused by an event beyond its reasonable control, including failures of third-party infrastructure or model providers, provided it takes reasonable steps to mitigate.
Notices
Notices to us should be sent to info@quaestra.ai. Notices to you will be sent to the email address on your account or shown in the product.
Governing law and jurisdiction
These terms and any dispute arising out of them, including non-contractual disputes, are governed by the laws of England and Wales.
The courts of England and Wales have exclusive jurisdiction, except that (a) consumers may bring proceedings in the courts of their country of residence where local law gives them that right, and (b) we may bring proceedings to protect our intellectual property or confidential information in any competent court.
