Each Chrome extension grants the user the following default rights:
5.2 You grant the user a non-exclusive, worldwide and perpetual license to execute, display and use the Products and any content contained in, accessible or transmitted through the Products in connection with Google Chrome. If you choose, you can include a separate End User License Agreement (EULA), which will regulate the rights of users to Products instead of previous offers.
Read the entire agreement here: http://developer.chrome.com/webstore/terms
In addition, you need to talk with the developer in question. Itβs annoying that the Google store doesnβt display the license terms for each extension by default.
