We may collect the following information for the purposes described in this policy, including:

This information is used to process your order. If we have trouble processing an order, we’ll use this information to contact you. Providing your personal data to us is necessary for processing your order for the purchase of products on the website and supplying other services provided on the website upon your request, or when your personal data is needed to fulfill obligations required by law or regulations. The refusal to provide us with any personal data necessary for performing the above purposes may consequently prevent us from processing your order for the purchase of products sold on the website or fulfilling obligations required by law and other regulations.

If you have checked the box that it is acceptable for us to contact you for marketing purposes, we may contact you from time to time to follow up on your satisfaction with our products and services, to announce new product offerings, or to conduct customer surveys that will help us in new product or service offerings. We may contact you by email, phone, or mail. We may use the information to customize the website according to your interests. However, we will not sell or distribute your personal information to third parties.

We collect and use your information for a variety of business purposes that are in our legitimate interests, in order to enter into or perform a contract with you, with your consent, or to comply with our legal obligations. For certain types of personal data, we have asked for your consent to use the data for certain described purposes at the time you provided it. You may withdraw your consent at any time by sending an email to

We are committed to ensuring that your information is secure. To prevent unauthorized access or disclosure we have put in place suitable physical, electronic and managerial procedures to safeguard and secure the information we collect online.

While we take reasonable steps to protect your personal data, we cannot guarantee that the personal data you disclose to us will be 100% secure. You accept the inherent security implications of dealing on-line over the internet and will not hold Prism or their processors responsible for any data breach unless it is due to our negligence.

We use cookies to make this site as useful as possible. Most websites you visit will use cookies in order to improve your user experience by enabling that website to “remember’” you, either for the duration of your visit (using a session cookie) or for repeat visits (using a persistent cookie).

A cookie is a simple text file that is stored on your computer or mobile device by a website’s server and only that server will be able to retrieve or read the contents of that cookie. Each cookie is unique to your web browser. It will contain some anonymous information such as a unique identifier and the site name and some digits and numbers. It allows a website to remember things like your preferences or what’s in your shopping cart.

We use cookies that are strictly necessary to enable you to move around the site or to provide certain basic features. We also use cookies to help us to improve the performance of our website to provide you with a better user experience.

We use session cookies to remember what you’ve put in the shopping cart. These we deem strictly necessary to the working of the website. If these cookies are disabled, then various functionality of the site will be broken.

These are cookies that are set on your computer or mobile device by this website directly: Google Analytics – We use Google Analytics to collect information about visitor behavior on our website. Google Analytics stores information about what pages you visit, how long you are on the site, how you got here, and what you click on. This Analytics data is collected via a JavaScript tag in the pages of our site and is not tied to personally identifiable information. We therefore do not collect or store your personal information (e.g. your name or address) so this information cannot be used to identify who you are.

These are cookies set on your computer or mobile device by external websites whose services are used on this site. Cookies of this type are the sharing buttons across the site allowing visitors to share content onto social networks such as Twitter, Facebook, Google+, and Pinterest. In order to implement these buttons and connect them to the relevant social networks and external sites, there are scripts from domains outside of our website. You should be aware that these sites are likely to be collecting information about what you are doing all around the internet, including on this website.

We will only keep your personal data for as long as reasonably necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, accounting, or reporting requirements.

If you are visiting the website from outside the United States, please be aware that you are sending information (including personal data) to the United States where our servers are located. That information may then be transferred within the United States or back out of the Unites States to other countries outside of your country of residence, depending on the type of information and how it is stored by us. These countries (including the United States) may not necessarily have data protection laws as comprehensive or protective as those in your country of residence; however, our collection, storage and use of your personal data will at all times continue to be governed by this policy.

Our website may contain links to other websites of interest. However, once you have used these links to leave our site, you should note that we do not have any control over that other website. Therefore, we cannot be responsible for the protection and privacy of any information which you provide while visiting such sites and such sites are not governed by this privacy statement. We also have no control over the nature and content of those sites. The inclusion of any links does not necessarily imply a recommendation or endorse the views expressed within those sites.

The information contained in this website is for general information purposes only. The information is provided by Enthalpy and while we endeavor to keep the information up-to-date and correct, we make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with respect to the website or the information, products, services, or related graphics contained on the website for any purpose. Any reliance you place on such information is therefore strictly at your own risk.

All updates to our Privacy Policy will be posted on this page. If Enthalpy plans to use your personal data for a new purpose, it will update this page and communicate the changes to individuals before starting any new processing. Visitors should check this page periodically for any updates.
