Terms of Use

There is no guarantee given as to the completeness accuracy or currency of any information or data on this web site. Flow Simulation Ltd. does not accept responsibility for any loss or damage caused by use of the information contained in this web site or any software downloaded from it. Software downloaded from the server is subject to the licensing terms in the Licence Agreement that accompanies the software. All access and use is at the risk of the user.

Online Privacy Policy

We are committed to respecting your online privacy and recognize your need for appropriate protection and management of any personal information you share with us. We do not make any information we obtain as a result of your using this site available to third parties. Flow Simulation Ltd. is the sole owner of any information collected. Any information you supply to us is used only for the purpose indicated. We take all reasonable precautions to protect the information you supply to us from unauthorized access or disclosure. Though we would make every effort to preserve user privacy, we might have to disclose personal information by law if we were ever required to comply with a judicial proceeding, court order or legal process served on us.

We do not require you to "log in", register or supply information to us in order to use this web site. We do not use browser visitor tracking devices. If you use the site to register software, we will collect contact information from you which is used to enable us to keep you informed about updates to and new versions of the software.

If you use the site to place an order directly with us, (as opposed to through an external site such as Amazon.com), we will collect contact information (e.g. name, email and shipping address) in order to be able to fulfil the order and financial information (e.g. credit card number and expiry date) for billing purposes. We may use an outside shipping company to ship orders, and a credit card processing company to bill users for goods and services. These companies have advised us that they do not share information with other parties, or use personally identifiable information for any secondary purposes without your permission.

Like most web sites, our web servers log IP addresses, browser and platform type, date and time, and referring pages only for the purpose of overall statistical analysis of web site usage patterns. From time to time we also use tracking mechanisms such as Google Analytics in order to collect statistical data about visits to our site.

We occasionally use third-party advertising companies to serve advertisements when you visit our website. Companies like Google may use information (which they tell us does not include personal information such as your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you. More information about this practice and your choices about how this information is used can be found on Google's website.

Apparently some new European laws require that we obtain your consent before we use cookies and so forth, and give you a mechanism to control our use of cookies. We don't use cookies or do any bad stuff, but we do have Google ads on a few pages (see below) and we can't make any guarantees about what Google may or may not do with cookies to personalise content and ads, to provide social media features and to analyse traffic. For all we know they may be sharing information about your use of our site with their social media, advertising and analytics partners. Scary.

We have come up with the following cookie control mechanism: if you want to ensure that doesn't happen you're going to have to stop using our site (along with most of the rest of the Internet, unfortunately). Sorry about that.

We do not use unsolicited bulk email.

Accessibility

We have tried to keep the content simple and limited to standard browser features. We don't presume to tell you which browser to use or require you to download the latest multimegabyte Realwave Flashtime (TM) plug-in. We make minimal use of HTML frames. We have used JavaScript only on pages where it is necessary, and these pages should still work acceptably even if scripting is disabled (or unsupported) in the browser. We have tried to keep our HTML consistent with W3C recommendations.

These constraints make it more likely that our site will be useable with less common browsers and with Assistive Technology such as screen readers. It should also ensure that our pages load reasonably quickly even on a modest speed internet connection. But we still have some work to do to make our site fully accessible and we are working towards achieving "double A" accessibility as specified in the WCAG 2.0 guidelines.

We are an Amazon.com associate. This means that if you follow one of our links to Amazon.com and buy something, we get a small commission. This helps us pay for the free software and services we provide on this site.

Some pages may contain Google advertisements. This also results in a small amount of revenue that helps pay for free services. The particular advertisements displayed are chosen by Google, and are usually relevant to the page on which they are shown, but we have no control over what is shown, nor can we take any responsibility for the sites they link to.

If you are a professional journalist we have an on-line media kit for our calculator software which you can use. Alternatively, if you contact us with your mailing address we can send you the media kit on CD-ROM.
