► When you click the green arrow, Solve or Simulate button, the add-in and its Web server interacts with the Azure Authentication Service and your online storage server to obtain an access token. As you define your model, cell selections and options are stored in properties, which will be saved when your Excel workbook is next saved to online storage.

► When you activate a modern add-in, its code is downloaded from Frontline's Web server into your browser, where it runs and displays its task pane. ► When you use Excel Online, the contents of your Excel workbook, rendered as HTML, CSS and JavaScript, is securely transferred over the Internet to your browser (using TLS 1.2 - Transport Layer Security).

► When you insert a modern (JavaScript-based) add-in into your workbook, only a "pointer" to a Web server (operated by Frontline Systems, also on Windows Azure) is stored. Your workbook is held in encrypted temporary storage on Windows Azure, and is deleted immediately after use.įor more information about modern add-ins for Excel Online, Excel for Windows and Macintosh, see Privacy and security for Office Add-ins.
The actual transfer of your Excel workbook contents between online storage and your browser, and between the online storage and our RASON Server, is encrypted using the industry standard Transport Layer Security (TLS) protocol. You will see a pop-up window in your browser, saying that the add-in wishes to read your workbook, with a button "Trust It." Only when you click this button will the workbook be transferred to the RASON Server, using a limited-lifetime, secure ( OAuth 2.0) access token. Protecting Your Privacy and Information Securityīecause Office 365, SharePoint, OneDrive and Google protect your Excel workbooks and other data, before our RASON Server can access your workbook, you must give your permission. You should only use these add-ins if you are comfortable with the privacy implications of this process. Solver and Risk Solver add-ins for Google Sheets have a similar EULA and disclaimers.
Free excel add ins license#
While this entire process is designed to be secure, you should be aware of it.įrontline's add-ins for modern Excel are offered under the Office Store's standard End User License Agreement (EULA) or under Frontline's own License and Warranty, both of which disclaim or limit all warranties, exclude or limit remedies and damages to the maximum extent permitted by law, and specify that you bear all risk of using these add-ins.
Your model is solved using the RASON Server's resources (processor and memory). For this to happen, it's necessary to transfer a copy of your Excel workbook, over the Internet, from its online location to our RASON Server. When you use one of our modern add-ins to solve an optimization, simulation and data mining problem, the actual solution is computed by Frontline's RASON® Server, operating as a "cloud service" on Windows Azure. Your Excel workbook is stored online, in an Office 365, OneDrive or Google Drive file. Modern Excel, Google Sheets, and Frontline's modern (JavaScript-based) add-ins operate differently. Neither Microsoft nor Frontline Systems ever "sees" your Excel workbook, unless you provide it separately, for example in technical support. Your Excel workbook is opened from disk, and solved "in place" using your PC's own resources (processor and memory). The Solver add-in is installed on your local PC. This section of our Privacy Policy will help you understand the privacy implications of "solving your model in the cloud." How Modern Add-ins Workįor many years, users like you have defined and solved models in Excel workbooks stored on their local PCs, using the Solver add-in included in Microsoft Excel (which was developed by Frontline Systems). You can also use Solver and Risk Solver add-ins for Google Sheets. With modern (JavaScript-based) Excel add-ins from Frontline Systems, you can define and solve optimization, simulation and data mining problems in your Excel workbook, using Excel Online in Office 365, Excel on iPad, or in desktop Excel for Windows or Macintosh (collectively, "modern Excel").
