Viper Copyright © 2017 by All Answers Limited. All rights reserved. The terms and conditions of this Licence applies to all versions of VIPER. By using Viper, you agree to all of the terms of this agreement. Please read the Licence terms below. If you do not agree to all of the terms of this Licence, then do not register for or use Viper.

1. Scope of Licence

1.1 Subject to the terms below, you are hereby Licensed by All Answers Limited to create a single user account in order to use Viper. Unregistered use of Viper is in violation of U.K. and international copyright laws.

1.2 You are specifically prohibited from charging, or requesting donations, for any copies, however made, and from distributing such copies with other products of any kind, commercial or otherwise, without prior written permission from All Answers Limited. All Answers Limited reserve the right to revoke the above distribution rights at any time, for any or no reason.

1.3 You may not alter or modify the Viper Software, nor give anyone permission to do so. All rights of any kind in Viper which are not expressly granted in this Licence are entirely and exclusively reserved to and by All Answers Limited. You may not rent, lease, modify, translate, reverse engineer, decompile, disassemble, or create derivative works based on Viper. You may not make access to Viper available to others in connection with a service bureau, application service provider, or similar business.

2. Credits, Payments and Refunds

2.1 Credits can be purchased to perform scans on your documents within the scope of this licence at the rates shown on our Pricing Page.

2.2 Each credit grants a scan of a document containing up to 30,000 characters (approximately 5000 words). Any documents containing more than 30,000 characters will use multiple credits on the basis of 30,000 characters per credit, depending on the character count of the document.

2.3 All Answers reserves the right to revise the purchase costs for credits and/or the character count limits per credit at any time. Any such revisions will be made on a commercial and/or operating costs basis but the value/number of existing credits may be upgraded upon request to ensure that existing credits have the same scan value after a revision to credit costs or character limits.

2.4 For the purposes of calculating the character count, this includes all that Microsoft Word would include in the character count of a document, save for footnotes/endnotes, and so includes, but is not limited to, numerical values, entries in tables, bibliographies, reference lists, abstracts, executive summaries.

2.5 You have the right to cancel an unused bundle within 24 hours of purchase. Provided no credits have been used since the credits were purchased, you are entitled to a full refund.

2.6 Leftover credits purchased as part of a bundle of 10 credits or higher may be refunded but only up to 10% of the credits are refundable on a pro-rata basis. Any leftover credits that constitute more than 10% of a purchased bundle are non-refundable.

2.7 For the purposes of the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, a bundle of credits is taken as a single purchase and upon the initiation of the first scan using the first credit, this is the point at which All Answers Ltd has commenced the provision of services for the bundle purchase.

2.8 If a Viper software scan completely fails to perform a scan on a document, a refund may be given for the purchase value of the scan. No such refund will be due where the failure of the scan to detect the significant plagiarism is as a result of user error, the user’s hardware or document compatibility or any attempt to falsify scan results.

2.9 It is acknowledged that matching content does not necessarily equal plagiarism and that the nature of any matching content is reviewed to determine whether matching content is in fact plagiarism.

3. Warranty Disclaimers and Liability Limitations

3.1 Viper, and any and all accompanying software, files, data and materials, are distributed and provided AS IS and with no warranties of any kind, whether express or implied. This disclaimer of warranty constitutes an essential part of this Licence.

5. Storage and use of scanned documents

5.1 We guarantee that we will not use your scanned document(s) for any other purpose than as explained in these licence terms and conditions.

5.5 All Answers Limited will automatically add a copy of that document to our archived documents database for comparison purposes only. This improves the accuracy of future scans for you and other users. All scans made by you and other users of the Viper software will be compared to the document you have scanned. If a match is detected with your scanned document in the database, the user of the Viper software will see the percentage of the match, the matching text will be highlighted in the new scan but the user will never see the archived document itself - your document is kept confidential.


5.6 When you scan a document using the free scan service, you grant All Answers Ltd a licence to use the scanned document for publication not less than 3 calendar months after the date the scan was initiated.

5.8 You agree that any right you may have to remuneration for such use of documents is waived.

5.9 You may not use the Viper Software to scan documents for which you do not hold sufficient intellectual property to be able to authorise us to use the documents in accordance with the terms of this licence.
