@Arindam-Bhowmik HI, as we describe in our terms of use, you are required to follow these points:
Attribution You must make sure that all of the Visualizations used in your Media include the source (preferably) in the form of the Windy logo or the following description in cases of small-size cut-outs: ‘Source: Windy.com’, and, where possible (e.g. when used on your website), include a hyperlink to the Windy Website.
Fair Use You may use the Visualizations in your Media as long as you do it fairly and not contrary to our interests in the development and promotion of our Services.
No Modification You are not allowed to modify the Visualizations other than as the Windy features allow you to do, but you may make necessary adjustments (such as scaling) required for their use in your Media.
