title: Google Product Sans font in Android Application, okay to use?
body: <p>I've seen the Google Product Sans font in quite a few popular apps on the Play Store, and available to download from a few places. (<a href="https://9to5google.com/2018/05/09/google-sans-vs-product-sans/" rel="nofollow noreferrer">https://9to5google.com/2018/05/09/google-sans-vs-product-sans/</a>)</p>
  
  <p>However, upon visiting the Google Fonts page for Product Sans it displays this message: <a href="https://fonts.google.com/license/productsans" rel="nofollow noreferrer">https://fonts.google.com/license/productsans</a></p>
  
  <blockquote>
    <p>Google offers many fonts under open source licenses. This is not one of them. Please see fonts.google.com for options you can use.</p>
  </blockquote>
  
  <p>Does not open source mean that we simply can't modify it, but we can use it? Would I be allowed to use this font in my Android application if I don't modify the font at all?</p>
