Terms and Conditions

Welcome to Opars (the “Site”), operated by Opars Ltd. These Terms and Conditions (“Terms”) govern your use of the Site and your purchase and access to all digital products provided through it. By accessing or using the Site, you confirm that you have read, understood, and agree to be bound by these Terms. If you do not agree, you should not use the Site.

We may revise these Terms from time to time to reflect updates in our services, policies, or applicable law. Changes take effect when posted on the Site, and your continued use after such posting constitutes acceptance of the updated Terms. These Terms operate in addition to any separate written agreement you may have with Opars Ltd.

1. Definitions

Digital Products means downloadable content (including books, journals, articles, maps, and curated collections) available for purchase on the Site. Institution means a university, library, research centre, or similar body acquiring licences for its authorised members. Account means a registered user or institutional profile on the Site through which purchases and access are managed.

2. Eligibility and Geographic Restrictions

The Site is available internationally, subject to applicable laws, export controls, and sanctions. By placing an order, you confirm you are legally permitted to do so in your jurisdiction. Orders originating from Iran cannot be accepted. We reserve the right to decline or cancel orders where fulfilment would breach applicable regulations.

3. Pricing Policy

All prices on Opars relate to online purchases and are listed in British Pounds (£), unless otherwise stated. Pricing may vary by content type (book, journal, map, or collection), collection size, and customer category (individual or institutional). Institutional pricing is generally higher due to broader hosting and access rights. Prices may be updated without notice; however, once an order is placed and confirmed, the price at checkout applies to that specific transaction.

4. Orders and Contract Formation

Orders can be placed directly through the Site. For institutional purchases, you may be asked to complete a descriptive agreement form before activation of access rights. An order is accepted when Opars Ltd issues a confirmation (e.g., by email) or enables access in your Account—whichever occurs first—at which point a binding contract arises between you and Opars Ltd. We may refuse or cancel orders where we reasonably believe there has been an error, misuse, or breach of these Terms.

5. Payment

Payment is due in advance unless otherwise agreed in writing. We accept Credit/Debit Cards, PayPal, UK Bank Transfer, and cheques drawn on UK banks. Proforma invoices may be issued for institutional or bulk orders. Orders are activated only after full cleared payment is received. All payments must be made in British Pounds (£) unless otherwise agreed.

6. Digital Delivery

Digital Products are supplied in digital format only. Upon payment confirmation, secure download links will be available via your Account on the Site. You are responsible for completing downloads within the timeframe shown in your Account and for storing and backing up files securely thereafter. While we strive to keep downloads available for a reasonable period, we do not guarantee indefinite re-download availability once files have been successfully delivered to you.

Institutions wishing to host purchased content on their own password-protected servers for campus access may do so provided they have agreed to the Opars Institutional Agreement terms. Public hosting or distribution outside the institution’s secure network is strictly prohibited.

7. Refunds and Cancellations (Digital Products)

Due to the nature of digital content, all sales are final once a file has been downloaded. Refunds or cancellations are not possible after download. Refund requests may be considered only within 7 calendar days of the purchase date and only if the Digital Product has not yet been downloaded. If you believe an error has occurred with your order, contact us immediately and refrain from downloading the file while we investigate.

8. Access Rights and Usage

Purchasing Digital Products grants perpetual, DRM-free access under the licence type purchased (individual or institutional). You may download and print purchased files for your own personal or institutional use. Reproduction of any purchased product for distribution or sales purposes—whether in print or digital format—is strictly prohibited. Redistribution, resale, public posting, automated harvesting, or sharing outside your permitted licence scope is not allowed. Institutions must ensure access remains restricted to authorised campus members and prevent external distribution.

9. Digital Collections and Subscriptions

We offer one-off purchases and subscription-based collections. Subscription access applies only to the subscription period paid for. Back issues and additional collections may be purchased separately. Once purchased, Digital Products remain available to you perpetually under your licence. Some curated collections may include an annual platform fee covering ongoing hosting and maintenance. Institutional alumni access, where offered, may be available at an additional charge and is subject to specific conditions stated at the time of purchase.

10. Access Methods

Purchased digital collections can be accessed in different ways depending on customer needs and subscription level. The main access methods are described below to help you choose the most appropriate option for your organisation or personal use.

Manual Login: Customers access the Site using the username and password created at registration. This method is suitable for individual users and smaller teams who prefer account-based authentication and personal download management.

IP-Based Authentication: Users visiting the Site from IP addresses within the institution’s registered range are automatically recognised and authenticated, enabling seamless access without individual logins. This method is suited to campus-wide access where many users need convenient, on-site availability of purchased content.

11. IP-Based Access

IP-based access is an optional paid service for institutions, subject to an annual fee based on the calendar year. This fee covers configuration and access control for your registered IP ranges on Opars. Failure to renew the annual fee will result in the reversion of access to standard username/password authentication methods.

The IP-based access service is provided on an “as is” basis. Opars Ltd does not guarantee compatibility with local network systems, EZproxy setups, firewalls, or other authentication layers implemented on customer networks. Institutions may request a trial before purchase to verify compatibility.

12. Privacy and Security

We respect your privacy. Please refer to our Privacy Policy for details on how we collect, process, and store personal data. Payment information is processed using industry-standard encryption. We do not store card details in plain text and take reasonable steps to safeguard your information from unauthorised access, alteration, or disclosure.

13. Use of the Site

You agree not to misuse the Site, including attempting unauthorised access, disrupting service, or engaging in automated scraping or data mining without our prior written consent. We may suspend or terminate Accounts, cancel transactions, or restrict access if we reasonably suspect misuse, fraud, or a breach of these Terms or applicable law.

14. Intellectual Property

All materials on the Site, including text, design, graphics, and Digital Products, are protected by copyright and related rights and remain the property of Opars Ltd and/or its suppliers. Purchase of Digital Products does not transfer copyright. You are granted a limited, non-transferable licence to use Digital Products solely as permitted under these Terms.

15. Indemnification

You agree to indemnify and hold harmless Opars Ltd from and against any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising from your misuse of purchased content, breach of these Terms, or violation of third-party rights.

16. Disclaimer and Limitation of Liability

The Site and all Digital Products and services are provided on an “as is” and “as available” basis. While we make reasonable efforts to ensure accuracy and availability, we do not warrant that the Site, downloads, or related services will be error-free, uninterrupted, or compatible with all systems. To the fullest extent permitted by law, Opars Ltd disclaims all implied warranties and will not be liable for any indirect, incidental, special, or consequential losses arising from the use of the Site or purchased products and services.

17. Governing Law and Jurisdiction

These Terms and any non-contractual obligations arising out of or in connection with them are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction to settle any dispute or claim arising out of or in connection with these Terms.

18. Termination

We may suspend or terminate your Account or access to the Site where we reasonably believe there is unlawful activity, abuse, fraud, or a material breach of these Terms. Termination does not affect rights and obligations accrued prior to termination, including payment obligations and licence restrictions on previously purchased Digital Products.

19. Miscellaneous

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions shall remain in full force and effect. These Terms constitute the entire agreement between you and Opars Ltd regarding the subject matter and supersede all prior or contemporaneous agreements. No waiver is effective unless in writing and signed by both parties.
