This Agreement is a legal document which sets out your rights and obligations, and those of Blue Duck Education Limited, a company registered in England under registration number 6626639 ("Blue Duck", "we" or "us"), in relation to this site and the games and other products and services offered by Blue Duck through it (collectively, the "Mangahigh Service").
The Mangahigh Service includes all versions of "Mangahigh", and any other online platforms released by Blue Duck from time to time, including all Blue Duck websites used to play the games that we make available. Mangahigh and Prodigi are Blue Duck trademarks.
You must take the time to read and understand this Agreement before registering for the Mangahigh Service. By registering, you accept that you are entering into a contract with us on the terms of this Agreement. Visitors to the Mangahigh Service who do not register to become a User (see 2 below) similarly affirm that they are bound by this Agreement each time they access the Mangahigh Service.
You should be aware that this Agreement may change from time to time in accordance with Clause 21 below.
Important: You must ensure that the email address we hold for you is kept up-to-date and that you have full access to it - we will be sending you important messages there.

If you create a school registration on the Mangahigh Service, you become a ‘User’. In becoming a User you warrant that: (i) you are of legal age to form a binding contract (or, if you are a minor, you have your parent's permission to use the Services, and your parent has read and agrees to this Agreement on your behalf); (ii) all registration information you submit is accurate and truthful; (iii) you will maintain the accuracy of such information; (iv) if you are accepting this Agreement on behalf of an institution, company or other legal entity, you have the authority to bind that institution, company or legal entity to this Agreement. You also certify that you are legally permitted to use and access the Services and take full responsibility for the selection and use of and access to the Mangahigh Service. This Agreement is void where prohibited by law, and the right to access the Mangahigh Service is revoked in such jurisdictions.
As a User, you also warrant that you will only grant access codes to teachers and staff members who are current employees of your school or district. Upon termination of a teacher or other staff member's employment with you, you will require such individual to return and cease using all access codes he or she has in his or her possession. If at any time you learn a user of the Mangahigh Service claims to be affiliated with your school or district who is not, in fact, affiliated with your school or district, you will notify Blue Duck immediately.
You must not choose a username or institution name that could potentially infringe anyone's rights, which is intended to confuse, or which is offensive, hurtful or otherwise inappropriate, as reasonably determined by us. We may change a username if we think it offends this Agreement.
If you are provided with login information for the Mangahigh Service by your teacher, parent, or other bona-fide User, you become a "Student". Students divide between those for whom a subscription fee is paid ("Members"), and non-Members. Members' subscriptions can be obtained and paid-for by a parent or guardian, or by an institution (such as a school) or another enterprise.
If an institution (such as a school) or another enterprise is providing your Membership of the Mangahigh Service, note that you may only use your Membership for so long as that institution or enterprise permits you to do so.
You can see the benefits of becoming a Member by visiting our Membership page.
Parents or guardians can also sign-up to pay for a subscription on the Membership page.
Note that we are not an internet service provider. In order to avail of the Mangahigh Service, you must have internet access and all the software (and skills) required for email and web usage.
Blue Duck collects limited personal information from minor Students, but only where that Student's school, district, and/or teacher has contracted with Blue Duck (by agreeing to these Terms and Conditions) to collect personal information from Students for the use and benefit of the learning environment. Blue Duck requires schools, districts, and/or teachers to obtain parental consent from Students' parents before collecting any such personal information. If you are a Student, please do not send any personal information about yourself to us, other than what we request from you when you sign up for the Services. In the event that we learn that we have collected personal information from a Student without parental consent being obtained by his or her school, district, and/or teacher, or if we learn a Student has provided us personal information beyond what we request when he or she signs up for the Website, we will delete that information as quickly as possible. If you believe that a Student may have provided us personal information beyond what is requested when signing up for the Website, or that a Student's school, district, or teacher has not required parental consent prior to our collection of any personal information, please contact us at .
We are not and cannot be responsible for the behaviour of Users and Students - whether on the Mangahigh Service or outside of it. In particular, you should be aware that Blue Duck does not generally pre-screen or monitor the material contributed by Users and Students. You can report all inappropriate communication or behaviour to us at .
We provide you with access to mathematics education, games and other software ("Software") through the Mangahigh Service. We grant you a personal, non-exclusive, non-transferable, limited licence to use the Software on any compatible computer from which you access the Mangahigh Service. All Software is protected by copyright and other intellectual property laws and treaties and is owned by us, our affiliates or licensors. You may not sell or redistribute the Software. You may not incorporate it or any portion of it into another product. You may not reverse engineer, decompile or disassemble the Software or otherwise attempt to derive the source code, except where expressly permitted by law to do so. You may not modify, adapt or create derivative works from the Software in any way or remove proprietary notices in the Software.
Blue Duck or its affiliates may offer new or additional services through the Mangahigh Service from time to time. Your use of them may be subject to additional terms and conditions, or rules of use, which you must comply with. Any failure by you to comply with a material provision of the terms or rules governing such additional services will amount to a breach of this Agreement.
Blue Duck reserves the right to withdraw or modify aspects of the Mangahigh Service, or the entirety of it, where we have legal or commercial reasons to do so. There may also be times when the Mangahigh Service becomes inaccessible as a result of technical difficulties experienced by Blue Duck or on the Internet; we will, however, use reasonable skill and care to overcome these difficulties where they are within our control.
There may be times when we make the Mangahigh Service unavailable so that we can conduct technical work on it. We will try to ensure that this planned downtime occurs only between 7am and 9am on Thursdays or is as otherwise specified in the Frequently Asked Questions section on the Mangahigh Service.
Note that we will never ask you for your password, and that you are solely responsible for maintaining the safety and secrecy of your password and any additional identifying information. You will be responsible for the activities of anyone who uses your password to gain access to your account. If you think that someone may have obtained your password, you must change it immediately.
We reserve the right (a) to suspend or terminate any User's access to the Mangahigh Service, or parts of it, and/or (b) to remove, or require the User to remove, material posted on the Mangahigh Service, if the User or material appears to us, or to someone who has complained to us, to be in breach of any provision of this Agreement.
Any person whose access has been suspended or terminated must not re-register for, or re-access, the Mangahigh Service without our prior consent. You are responsible for everything which is done on or through the Mangahigh Service while your Users account is logged on to the Mangahigh Service, or through your email address(es). In addition, we reserve the right to suspend or terminate any User's access to the Mangahigh Service, or parts of it, if the relevant User is abusive, discriminatory or threatening, or harasses or communicates offensive messages or images to another User, whether or not through the Mangahigh Service.
For completeness, where we reserve a right in this Agreement, it does not mean we will be obliged to exercise it. Also, given the open-access nature of the Mangahigh Service, note that we cannot prevent determined people whose Users has been suspended or terminated from re-accessing the Mangahigh Service or re-registering as Users, in breach of their obligations under this Agreement.
The Mangahigh Service is intended to be used by its Users and Students for the purposes we describe in this Agreement and on the Mangahigh Service itself. Accordingly, Users and Students must not:
place material on, or otherwise use, the Mangahigh Service for any business or commercial purpose; or
use your access to the Mangahigh Service, or information gathered from it, in connection with the sending of unsolicited bulk email (sometimes known as spam).
If you are (or become) a Member, note that if the subscription paid by your parent, guardian, institution (such as a school) or other enterprise, is not paid or renewed, your Membership will come to an end, and you will only have the ability to access the Mangahigh Service as a User.
You must ensure that any material you post, or which is posted through a machine on which you access the Mangahigh Service, and all your activity and communication on the Mangahigh Service, is not capable of (a) infringing the intellectual property or other rights of any person or entity, (b) breaching any applicable law, whether criminal, tortious or otherwise, (c) appearing to be offensive, threatening, abusive, discriminatory, obscene, pornographic, false, libelous, defamatory, unreliable or misleading, or (d) being perceived as antisocial or disruptive.

Blue Duck has no control over or responsibility for the truth or accuracy of any material available on the Mangahigh Service that is provided by Users or others.
If any third party sites are linked to from the Mangahigh Service, this does not mean that we endorse or have any responsibility for the site in question or anything which appears on it.
You should exercise no lesser degree of caution in appraising what you see on the Mangahigh Service than you do offline.
Even though Users and Students are prohibited from doing so, people may provide information, or otherwise behave, in a way that is unreliable, misleading or even illegal. Further, you should note that people may not necessarily be who they say they are.
Therefore, to the extent that the law permits, you release Blue Duck its directors, contractors and employees from all liability (including in relation to disputes with other Users) arising out of your use of a third party site or arising out of or in connection with the material included on the Mangahigh Service by Users and other third parties.

These rights protect all of the games you see on the Mangahigh Service, including the graphics of those games, their structure, gameplay and their "look and feel". It is easy to copy material which appears on web-sites, but this does not mean it is legal. Therefore, no-one may copy, distribute, show in public or create any derivative work from the Mangahigh Service, or any part of the games or other material which is found on the Mangahigh Service unless properly licensed to do so by us.
By submitting any material to the content to the Mangahigh Service, you:
are representing that you are fully entitled to do so;
grant us a non-exclusive, royalty-free, non-terminable licence to copy, modify, distribute, show in public and create derivative works from that material in any form, anywhere; and
authorise us to adapt the relevant material in the course of doing so, and so waive your moral rights to object to any derogatory treatment, or to be identified as the author, of the material in question.
We will not be liable to you or any third party for any loss not reasonably foreseeable by us when this Agreement commences, for any indirect or consequential loss or damage, or for any loss of data, profit, revenue or business, howsoever caused (whether arising out of any negligence or breach of this Agreement or otherwise). Blue Duck will also not be liable for any failure to perform of its obligations under this Agreement caused by matters beyond its reasonable control.
Without limiting the preceding Clause, the aggregate liability of Blue Duck under this Agreement (whether arising in negligence or otherwise) will not under any circumstances exceed an amount equal to (a) the monthly Subscription fee payable by parents or guardians at the time liability arises, or (if greater) (b) the sums that have actually been paid for your then-current Membership.
Nothing in this Agreement limits our liability for death or personal injury resulting from our negligence, or any other liability which may not by law be excluded. Any statutory rights you may have as a consumer remain unaffected.
You agree to indemnify us against all liabilities, claims and expenses that may arise from any breach of this Agreement by you or through a machine on which you access the Mangahigh Service.
We reserve the right to assign this Agreement, and to assign or subcontract any or all of our rights and obligations under this Agreement, but will not do so in such a way as to reduce any guarantees you are given under this Agreement.. You may not without the written consent of Blue Duck assign or dispose of this Agreement.
Blue Duck reserves the right to change this Agreement from time to time, and post the new version on the Mangahigh Service.

This Agreement, and any new version of it in the future, takes effect immediately. However, if you do not wish to be bound by the changes we make in this Agreement (or any new version of it), then you can choose instead to remain bound by the previous Blue Duck Terms and Conditions until:
the next renewal date for the subscription fee payable by your parent or guardian, or (if you are using the Mangahigh Service at school) your school, if you are a Member; or
one month after the date when we post the new version, if you are a User.
In the event that any term of this Agreement is held to be invalid or unenforceable by judicial decree or decision, the remainder of this Agreement shall remain valid and enforceable.
This Agreement shall be governed by and construed in accordance with the laws of England and Wales.

These are the Terms and Conditions that apply to institutions and businesses that agree to obtain multiple Memberships of (the "Mangahigh Service"), and, together with the Mangahigh Purchase Order that refers to these Terms and Conditions (the "PO"), form the "Agreement".
The Agreement is between the business or institution specified in the PO (the "Enterprise" or "you") and Blue Duck Education Limited, a company registered in England under registration number 6626639 ("Blue Duck", "we" or "us").
The PO specifies (a) the number of Memberships of the Mangahigh Service that the Enterprise is subscribing for (the "Subscription"), and which are to be provided for the benefit of the Enterprise’s students, users or customers ("End-Users"), (b) the Price of the Subscription fees that are to be paid to us for those Memberships, and (c) the "Term", at the end of which all the Memberships will cease.
The Enterprise must nominate the End-Users who are to be granted Membership, up to the maximum number for which the Subscription fees are paid. If an End-User ceases his/her Membership before the end of the Term, he/she may be replaced as a Member by another End-User nominated by the Enterprise. It is the Enterprise’s responsibility to administer the allocation of Memberships to its End-Users.
The Enterprise must ensure that the email address we hold on behalf of it is kept up-to-date – we will be sending important messages to it. If that email address changes, then you must notify us of the new address in accordance with Clause 16 below.
Each End-User must agree to our "User Agreement" () as a condition of using the Mangahigh Service. If an End-User does not do so, this will not entitle you or the Enterprise to any rebate of the Subscription fees that are paid to us.
An End-User is referred to in the "User Agreement" as (a) a User, and (b) a Member where he or she avails of a Membership of the Mangahigh Service under your Enterprise’s Subscription. "User" and "Member" have the same meanings in this Agreement.
The Enterprise agrees to take responsibility for End-Users' (a) use of the Mangahigh Service, and (b) compliance with the "User Agreement".
You can see the benefits of Membership on our home page ().
Note that we are not an internet service provider. In order to avail of the Mangahigh Service, each End-User must have internet access and all the software (and skills) required for email and web usage.
The Subscription permits the number of Memberships for the Term identified in the PO. All Memberships will come to an end when that Term ends (irrespective of how long an individual End-User has held that Membership).
The Term runs from the date when we notify you by email that we have made Membership available to End-Users. We will give this notice to you after you pay the relevant Subscription fee, or (if, in our discretion, we are prepared to do so in advance of receiving that fee) following the execution of the PO.
You agree to pay the Price for Subscription within 14 days of any invoice we issue. We will be entitled to charge interest on any sums owed to us at the rate of three percent per annum above the then-current base rate of HSBC Bank Plc from the date payment becomes due until payment in full.
For the avoidance of doubt, there is no right to cancel the Enterprise’s Subscription during the cooling-off period which is provided for certain purchases under the Consumer Protection (Distance Selling) Regulations 2000.
Please note that we reserve the right to change the amount of the Subscription fee, the period which it covers and the Mangahigh Services that it enables End-Users to obtain. However, these changes will not take effect until the end of the Term.
We will not be liable to you or any third party for any indirect or consequential loss or damage, or for any loss of data, profit, revenue or business, howsoever caused (whether arising out of any negligence or breach of this Agreement or otherwise). Blue Duck will also not be liable for any failure to perform of its obligations under this Agreement caused by matters beyond its reasonable control.
Without limiting the preceding Clause, the aggregate liability of Blue Duck in connection with this Agreement, whether arising in negligence or otherwise, in any successive twelve-month period (the first such twelve-month period commencing on the date when the Term commences) will not under any circumstances exceed the greater of (a) £50, or (b) the sums that you have actually paid to us by way of Subscription fees in respect of that twelve-month period.
Nothing in this Agreement limits our liability for death or personal injury resulting from our negligence, or any other liability which may not by law be excluded. Any statutory rights of consumers remain unaffected.
The Enterprise agree to indemnify us against all liabilities, claims and expenses that may arise from any breach of (a) this Agreement by the Enterprise, or (b) the "User Agreement" on the part of any of the End-Users.
We reserve the right to assign this Agreement, and to assign or subcontract any or all of our rights and obligations under this Agreement. You and the Enterprise may not without the written consent of Blue Duck assign or dispose of this Agreement.
This Agreement, including any documents incorporated into it, contains the whole of the agreement between us and the Enterprise concerning its subject-matter, replacing all earlier or other agreements and understandings, except for any fraud or fraudulent representation. A person who is not a party to this Agreement has no right under the Contracts (Rights of Third Parties) Act 1999 to rely upon or enforce any term of this Agreement.
Blue Duck reserves the right to change these Terms and Conditions from time to time, and post the new version on the Mangahigh Service. When we do so, we notify the fact that there are changed terms at and post the new Agreement there. However, if the Enterprise does not wish to be bound by the changes we make in any new version of these Terms and Conditions, then it can choose instead to remain bound by these Terms and Conditions until the end of the Term.
In the event that any term of this Agreement is held to be invalid or unenforceable by judicial decree or decision, the remainder of this Agreement shall remain valid and enforceable.
This Agreement shall be governed by and construed in accordance with the laws of England and Wales, and is subject to the non-exclusion jurisdiction of the English courts.
We shall be entitled to suspend or terminate any or all Memberships immediately in the event that you are in breach of this Agreement, and have failed to correct that breach within 7 days of any notice from us specifying the breach.
The Enterprise may contact us by post at or by Fax on . Please make sure you include your full name and email address with all correspondence. Our VAT number is . We are entitled to serve any notice on you under or in connection with this Agreement by sending an email to the email address specified in the PO, which you can change by notifying us of the new email address by post or fax as provided in this Clause.
Apart from user initiated actions (such as password resets), we only send e-mails to users that have either opted-in to receive them or are paying for a subscription to Mangahigh for full access to our site.
We will send our members an e-mail invoice on the anniversary of their account, when the payment is processed (successfully or unsuccessfully).
Also, we will notify our members by email of:
any significant change to our terms and conditions
any significant change to our service such as withdrawal of functionality or pricing changes
We will send no more than 1 email a week detailing changes and updates to the Mangahigh service: this could be addition of new games, availability of new lessons on Prodigi®, changes to pricing or other similar announcements.
