1. Acceptance of these Terms
These Terms of Use (the “Terms”) form a legally binding agreement between you and Perquira (“Perquira”, “we”, “us” or “our”) governing your access to and use of the Perquira research platform, the website at perquira.com and any related software, features, content and services (together, the “Service”). In these Terms, “you” means the individual accessing or using the Service and, where that individual uses the Service on behalf of an employer, university or other organisation with authority to bind it, that organisation.
By creating an account (an “Account”), accessing or using the Service, purchasing a paid plan, or otherwise indicating your acceptance, you confirm that you have read, understood and agree to be bound by these Terms, our Privacy Policy and our Refund Policy, each of which forms part of these Terms. If you do not agree, you must not access or use the Service.
2. Eligibility and Accounts
You must be at least 16 years of age, or any higher age required to form a binding contract in your jurisdiction, to use the Service. By using the Service you represent and warrant that you meet this requirement and that you are not prohibited from receiving the Service under any applicable law.
Some features require an Account. You may sign in using a link sent to your email address or through a supported third-party sign-in provider. You agree to provide accurate information, to keep access to your email account and sign-in methods secure, and to notify us promptly of any unauthorised use. You are responsible for all activity that occurs under your Account.
Each Account is personal to a single individual. You may not share your sign-in, permit any other person to use your Account, transfer, sell, sublicense, lend or otherwise make your Account or plan available to any third party, or create or use more than one Account in order to obtain additional free or paid allowances. We may suspend, merge or close Accounts that do so, without refund.
3. The Service
The Service helps users discover and organise scholarly evidence, analyse selected papers, identify research opportunities, compare journals and locate open calls for papers. The Service relies on automated processing, including artificial-intelligence models, and on scholarly databases operated by third parties.
We may add, change, limit, suspend or remove any feature, coverage, database, allowance or part of the Service at any time, with or without notice, including for reasons of security, reliability, cost, legal compliance or product development. We do not guarantee that the Service or any feature will be continuously available, uninterrupted or error-free. If you do not agree with any change to the Service, your sole remedy is to stop using the Service and cancel your plan.
4. Paid Plans, Billing and Taxes
Paid plans (each a “Paid Plan”) are offered on the terms, prices and monthly allowances shown on our pricing page at the time of purchase. Paid Plans are sold and billed by Paddle.com Market Limited and its affiliates (“Paddle”), which acts as our merchant of record and authorised reseller. Your purchase is also subject to Paddle’s buyer terms, and Paddle is responsible for processing payment, calculating and collecting applicable taxes, and issuing invoices and receipts.
Paid Plans are billed monthly in advance and renew automatically at the end of each billing period at the then-current price until cancelled. By purchasing a Paid Plan, you authorise Paddle to charge your selected payment method for all amounts due, including recurring subscription fees and applicable taxes. If a payment cannot be collected, we may suspend or downgrade your Account until payment is made.
We may change the price or allowances of a Paid Plan for future billing periods. Any change will apply from your next billing period after reasonable notice. If you do not agree to a change, you may cancel your Paid Plan before it takes effect.
5. Cancellation and Refunds
You may cancel a Paid Plan at any time through your Account or the link in your Paddle receipt. Cancellation takes effect at the end of the current billing period; you will retain access to the Paid Plan until then and will not be charged for further periods, after which your Account will revert to the Free plan.
EXCEPT AS EXPRESSLY STATED IN OUR REFUND POLICY OR AS REQUIRED BY APPLICABLE LAW, ALL PAYMENTS ARE NON-REFUNDABLE, INCLUDING FOR PARTIAL BILLING PERIODS, UNUSED ALLOWANCES AND PERIODS DURING WHICH THE SERVICE WAS NOT USED. Cancelling a Paid Plan does not entitle you to a refund of any amount already paid or relieve you of any amount already due.
6. Allowances and Fair Use
Each plan includes a set number of uses per calendar month for each feature, as shown on the pricing page. Re-running or reopening the same question, opportunity request or paper set within the same month does not count as an additional use. Unused allowances expire at the end of each month and do not carry over, accumulate or convert into credit or cash.
Allowances are provided for genuine individual research use. We may apply technical limits, rate limits or spending controls to protect the Service, and we may restrict or suspend use that we reasonably consider automated, abusive, excessive or intended to circumvent plan limits.
7. Your Content
“Your Content” means any questions, text, files, papers, manuscripts, data or other material that you submit to the Service. As between you and us, you retain all rights in Your Content. You grant Perquira and its service providers a limited, worldwide, non-exclusive, royalty-free licence to host, copy, process, analyse and transmit Your Content solely as necessary to provide, secure, maintain and improve the Service for you.
You represent and warrant that you own or have all rights, licences, consents and lawful bases necessary to submit Your Content and to grant the licence above, and that Your Content and its use through the Service do not infringe any intellectual-property, privacy or other right of any person or breach any law or agreement.
You must not submit identifiable patient information, protected health information, confidential research-participant records, examination materials, unlawfully obtained papers, or unpublished third-party manuscripts that you are not authorised to share. You are solely responsible for removing personal and sensitive data before submission. We have no obligation to review Your Content, but we may remove or disable any content that we reasonably believe breaches these Terms.
8. Outputs and Research Limitations
Outputs generated by the Service (“Outputs”), including evidence classifications, summaries, research opportunities, novelty assessments, journal matches and paper analyses, are produced by automated systems and may be incomplete, outdated, misclassified or incorrect. Literature searches are not exhaustive, and a statement that something was not found applies only to the evidence retrieved or selected unless expressly stated otherwise.
The Service does not provide medical, clinical, psychological, legal, financial or ethical advice, research-ethics approval, diagnoses or treatment recommendations, and does not guarantee novelty, publication, acceptance, funding or any other result. You remain solely responsible for your research design, methodology, ethical and regulatory compliance, verification of sources, quotations, citations, eligibility rules and deadlines, and for all decisions made using Outputs. You may use Outputs for lawful research and study, subject to the rights of third parties in the underlying sources.
9. Prohibited Uses
You may use the Service only in compliance with these Terms and all applicable laws. Without limiting that obligation, you must not, and must not attempt to or permit any other person to:
- copy, modify, translate, reverse engineer, decompile, disassemble or create derivative works of the Service or any part of it, except to the extent such restriction is prohibited by law;
- rent, lease, lend, resell, sublicense, redistribute or otherwise make the Service, your Account or your access available to any third party;
- access or use the Service through scripts, bots, scrapers or other automated means, or at a volume that exceeds normal individual use, or circumvent any access control, allowance, rate limit or spending control;
- use the Service or its Outputs to build, train or supply a competing product, service, model or dataset;
- upload or transmit malicious code, or interfere with or disrupt the integrity, security or performance of the Service or its infrastructure;
- submit content that is unlawful, defamatory, harassing, fraudulent, infringing or otherwise objectionable, or misrepresent your identity or the source of any content;
- generate or present fabricated scholarship, data or citations, or use Outputs to deceive any person, publisher, institution or funder;
- use the Service to make automated clinical, diagnostic or treatment decisions about any individual; or
- use the Service in any manner that violates the rights of others or any applicable law, or that could expose Perquira or its users to liability.
If you engage or attempt to engage in any of these activities, or otherwise use the Service in breach of these Terms, we may suspend or terminate your Account and access to the Service immediately and without refund.
10. Scholarly Content and Third-Party Services
The Service displays and links to metadata, abstracts and other material originating from third-party databases and publishers, including OpenAlex, Europe PMC and PubMed, Crossref, Semantic Scholar and ClinicalTrials.gov. Such material remains subject to the rights and terms of its owners. We do not control and are not responsible for the content, accuracy, availability or practices of any third-party source or service, and a link does not imply endorsement. Journal scopes, fees, deadlines and calls for papers may change, and you must verify them with the publisher before acting.
If you use a third-party service in connection with the Service, such as a sign-in provider or a reference manager, your use of that service is governed by its own terms and privacy practices, for which we have no responsibility or liability.
11. Our Intellectual Property
The Service, including its software, interface, design, selection and ranking logic, text, graphics and the Perquira name and branding, is owned by or licensed to Perquira and is protected by intellectual-property laws. Except for the limited, revocable, non-exclusive, non-transferable right to use the Service in accordance with these Terms, no right, title or interest in the Service is granted to you, and all rights not expressly granted are reserved. You must not remove or alter any proprietary notice in the Service.
12. Feedback
Any suggestions, ideas, comments or other feedback that you provide about the Service (“Feedback”) are non-confidential. You grant us a perpetual, irrevocable, worldwide, royalty-free licence to use, modify and incorporate Feedback into our products and services without any obligation or payment to you.
13. Suspension and Termination
These Terms remain in effect for as long as you access or use the Service. You may stop using the Service at any time and may request deletion of your Account by contacting us at contact@perquira.com.
We may suspend or terminate your Account or access to the Service, in whole or in part, at any time and without refund if you breach these Terms, misuse the Service, commit or attempt fraud, open a payment dispute without good reason, or create risk or possible legal exposure for us or other users, or where we are required to do so by law. We may also discontinue the Service for any reason. If we discontinue the Service or terminate your Account for reasons other than your breach of these Terms, we will refund any fees you prepaid for the period after the discontinuation or termination.
On termination, your right to use the Service ends immediately, and Your Content and other Account information may be deleted. Sections that by their nature should survive termination, including those concerning payments due, intellectual property, disclaimers, limitation of liability, indemnification and time limits for claims, will survive.
14. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE, ALL OUTPUTS AND ALL RELATED CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS OR QUIET ENJOYMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY OUTPUT OR RESULT WILL BE ACCURATE, RELIABLE OR SUITABLE FOR YOUR PURPOSES. WE ARE NOT RESPONSIBLE FOR ANY THIRD-PARTY CONTENT, DATA, SERVICE OR INFRASTRUCTURE.
15. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL PERQUIRA BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OPPORTUNITY, PUBLICATION, FUNDING OR REPUTATION, ARISING OUT OF OR RELATING TO THE SERVICE, ANY OUTPUT OR THESE TERMS, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, WHATEVER THE FORM OF ACTION, WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIFTY US DOLLARS (USD 50).
Some jurisdictions do not allow the exclusion or limitation of certain warranties or liabilities. In those jurisdictions, the exclusions and limitations above apply only to the extent permitted by law, and nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited.
16. Indemnification
To the maximum extent permitted by law, you agree to defend, indemnify and hold harmless Perquira and its service providers from and against any claims, losses, liabilities, damages, costs and expenses, including reasonable legal fees, arising out of or relating to Your Content, your use of the Service or any Output, your breach of these Terms, or your violation of any law or the rights of any third party.
17. Time Limit for Claims
To the maximum extent permitted by applicable law, any claim or cause of action arising out of or relating to the Service or these Terms must be commenced within one (1) year after the claim or cause of action arose, failing which it is permanently barred.
18. Dispute Resolution
We would like to understand and address any concern before formal action is taken. Before commencing any legal proceeding against us, you agree to send a written notice to contact@perquira.com with the subject line “Dispute Notice”, stating your name, the email address associated with your Account, a description of the dispute and the relief you seek. You and we will attempt in good faith to resolve the dispute informally for sixty (60) days after the notice is received. Any applicable limitation period will be suspended during that period to the extent permitted by law.
19. Changes to these Terms
We may revise these Terms from time to time. The revised version will be posted on this page with an updated effective date and, where the changes are material, we will make reasonable efforts to notify you by email or through the Service. Changes take effect when posted unless stated otherwise. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms to the extent permitted by law. If you do not agree, you must stop using the Service and cancel your plan.
20. General
These Terms, together with the Privacy Policy and the Refund Policy, constitute the entire agreement between you and Perquira regarding the Service and supersede any prior agreements on that subject. If any provision is held invalid or unenforceable, it will be enforced to the maximum extent permissible and the remaining provisions will remain in full force and effect. Our failure to enforce any right or provision is not a waiver of that right or provision. You may not assign or transfer these Terms or your Account without our prior written consent; we may assign or transfer these Terms to a successor to the Service without your consent. You agree that we may provide notices and communications to you electronically, including by email and through the Service, and that such communications satisfy any requirement that they be in writing. Headings are for convenience only, and the words “including” and “include” are illustrative and not limiting.
