End User Licence Agreement: What Is It And Why Do I Need One? (2025 Updated)

In this day and age, chances are you’ve agreed to an End User Licence Agreement (EULA) before. Whether you’re downloading a new app or installing a computer programme, these agreements have become a standard part of using digital products, ensuring both the developer and the end user understand their rights and responsibilities.

If you’ve downloaded any apps on your phone or programmes on your computer – then you may well have clicked a tick box (that you may or may not have read). These are typically referred to as EULAs, and their role in protecting intellectual property remains as critical in 2025 as ever.

Why Would You Need An EULA?

If you’ve developed an app or a software as a service, you might be thinking it’s enough to just have a SaaS Agreement in place. This can be the case when you are selling your software directly to consumers. However, when individual users – including businesses, students and individual consumers – download and use your software for various purposes, more comprehensive coverage is required.

When end users access your platform, you want to ensure they use your software in line with your guidelines. An effective EULA not only outlines what is permitted but also mitigates the risks of software misuse, unauthorised copying, and other potential liabilities.

There are two common scenarios regarding the need for an EULA.

Firstly, if you engage another business to market and sell your software, it is crucial that the end users adhere to clearly established terms. By requiring users to agree to an EULA upon download, you set out the rules on how your software should be used and help protect your intellectual property. You may also wish to read our guidance on website terms and conditions for more on setting clear user obligations.

Another common scenario arises when an enterprise purchases licences for its employees. In such cases, while the enterprise itself can be bound by your terms and conditions, ensuring that every employee complies with the stipulated conditions requires individual acceptance via an EULA. This extra layer of protection helps retain control over how your software is used, protecting both your business and your reputation.

What’s In An EULA?

SaaS Agreements and EULAs often go hand in hand. If you already have a SaaS Agreement, it is important to ensure that the drafting of your EULA is consistent with it. A well-drafted EULA can cover various areas of potential risk, and some typical clauses include:

• Prohibiting copyright infringement: Depending on the nature of your software – for example, if it allows users to share or post content – an EULA can restrict users from uploading any third-party material that infringes copyright. This clause is vital to limit your exposure to copyright claims.
• No reverse engineering: To protect your intellectual property and trade secrets, an EULA can explicitly prohibit users from reverse engineering the software. This prevents users from tracing the binary code back to the original source code.
• Terms of use for downloading, installing and using the software: A clear framework outlining how the software is to be downloaded, installed and used helps limit liability – whether it’s due to misuse or situations when the software is temporarily unavailable for upgrades and maintenance. For more comprehensive digital protection, consider our insights on online business legal requirements.
• Termination: In the case of misuse by an end user, the EULA should provide the developer or licensor with the ability to terminate access and take enforcement action. Such provisions are critical in maintaining control over your software environment.

In 2025, with evolving consumer protections and digital rights laws, it is also advisable to include clauses that address data privacy and compliance. This can ensure that your EULA aligns with updated legal standards and best practices in the tech sector.

How Can I Use An EULA?

EULAs can be tailored to the specific nature of your product. The two main forms are:

• A shrink-wrap licence: Traditionally used for software sold in physical packaging, a shrink-wrap licence becomes effective the moment the user removes the plastic wrapping. While less common today, this model is still relevant for certain packaged products.
• A click-wrap licence: This digital approach requires users to agree to the EULA by clicking a tick box or an “I agree” button before accessing the software. This method remains widely used and is legally enforceable, provided it is clearly presented to the user.

Given the evolving nature of software distribution in 2025, many developers now integrate EULAs seamlessly into their registration or installation processes. For additional guidance on drafting digital agreements, our contract drafting service can help ensure your EULA is robust and enforceable.

Furthermore, should your business expand into other digital products or services, you can explore our comprehensive range of legal documents, such as online service terms and intellectual property protection, to create a cohesive legal framework that supports your growth.
