<p>Intromax is committed to ensuring that the app is as useful and efficient as possible. For that reason, we reserve the right to make changes to the app or to charge for its services, at any time and for any reason. We will never charge you for the app or its services without making it very clear to you exactly what you&rsquo;re paying for.</p>
<p>The My Examiner app stores and processes personal data that you have provided to us, to provide our Service. It&rsquo;s your responsibility to keep your phone and access to the app secure. We, therefore, recommend that you do not jailbreak or root your phone, which is the process of removing software restrictions and limitations imposed by the official operating system of your device. It could make your phone vulnerable to malware/viruses/malicious programs, compromise your phone&rsquo;s security features and it could mean that the My Examiner app won&rsquo;t work properly or at all.</p>
<p>You need an account for most activities on our platform, including purchasing, enrolling in a course, and participating in exams. When setting up and maintaining your account, you must provide and continue to provide accurate and complete information. You have complete responsibility for your account and everything that happens on your account, including for any harm or damage, to us or anyone else caused by someone using your account without your permission.</p>
<p>We may terminate or suspend your account and bar access to Service immediately, without prior notice or liability, under our sole discretion, for any reason whatsoever and without limitation, including but not limited to a breach of Terms. If you wish to terminate your account, you may simply discontinue using Service. All provisions of Terms which by their nature should survive termination shall survive termination, including, without limitation, ownership provisions, warranty disclaimers, indemnity and limitations of liability.</p>

You represent and warrant that you have all the rights, power, and authority necessary to authorize us to use any content that you submit. You also agree to all such uses of your content with no compensation paid to you.</p>
<p>It may happen that our platform is down, either for planned maintenance or because something goes down with the site. It may also happen that we encounter security issues. You accept that you will not have any recourse against us in any of these types of cases where things don&rsquo;t work out right. In legal, more complete language, the Services, and their content are provided on an &ldquo;as is&rdquo; and &ldquo;as available&rdquo; basis.</p>

<p>You should be aware that there are certain things that Intromax will not take responsibility for. Certain functions of the app will require the app to have an active internet connection. The connection can be Wi-Fi or provided by your mobile network provider, but Intromax cannot take responsibility for the app not working at full functionality if you don&rsquo;t have access to Wi-Fi, and you don&rsquo;t have any of your data allowance left.</p>
<p>At some point, we may wish to update the app. The app is currently available on &ndash; the requirements for the system(and for any additional systems we decide to extend the availability of the app to) may change, and you&rsquo;ll need to download the updates if you want to keep using the app. Intromax does not promise that it will always update the app so that it is relevant to you and/or works with the version that you have installed on your device</p>
