A EULA, or End User License Agreement, is a legal contract between a software developer or publisher and the user of the software. It outlines the terms under which the user can use the software, including any restrictions, rights, and obligations. By agreeing to the EULA, users consent to abide by these terms, which can include limitations on copying, sharing, or modifying the software. EULAs are commonly presented during the installation process of software or when a user first opens an application. They serve to protect the intellectual property rights of the developer while informing users of their rights and responsibilities. Understanding a EULA is important for users to ensure they comply with the terms and avoid potential legal issues.
