End-User Software License Agreement Template

In plain language: Defines exactly what the user is permitted to do with the software — install on a specified number of devices, use for personal or commercial purposes, and for what duration.

Common mistake: Using an overly broad grant such as 'install on any device you own' without a seat or device limit. This prevents the publisher from upselling additional licenses and complicates enforcement.

In plain language: Lists prohibited activities — reverse engineering, sublicensing, redistribution, and using the software to build a competing product.

Common mistake: Omitting a prohibition on using the software to train AI or machine learning models. This gap is increasingly exploited, particularly with developer tools and data-processing software.

In plain language: Confirms that the publisher owns all rights to the software, its underlying code, documentation, and updates — and that the EULA is a license, not a sale.

Common mistake: Failing to state that the EULA is a license and not a sale. Without this language, the 'first sale doctrine' in the US may allow users to resell or redistribute their copy.

In plain language: Discloses what data the software collects from the user's device or usage, how it is stored and used, and references the publisher's full privacy policy.

Common mistake: Referencing a privacy policy URL that changes or goes offline. Courts have found that broken links undermine consent and may render the data collection clause unenforceable.

In plain language: States whether the publisher will provide updates, bug fixes, or new versions — and whether doing so is an obligation or purely at the publisher's discretion.

Common mistake: Promising automatic updates without reserving the right to change features or discontinue the software. This exposes the publisher to breach claims when updates alter functionality users depend on.

In plain language: Explicitly disclaims implied warranties — merchantability, fitness for a particular purpose, and non-infringement — so the publisher is not liable if the software fails to meet the user's expectations.

Common mistake: Using mixed-case or lowercase text for the disclaimer. In the US, the UCC and most courts require conspicuous, typically all-caps language for warranty disclaimers to be enforceable against consumers.

In plain language: Caps the publisher's total financial exposure to the user — typically the fees paid for the software in the prior 12 months — and excludes liability for indirect, consequential, or punitive damages.

Common mistake: Setting the liability cap at a nominal fixed amount (e.g., $100) rather than fees paid. Courts in several jurisdictions have struck down unconscionably low caps, especially in consumer-facing software.

In plain language: Specifies how long the license lasts, what events trigger automatic termination (e.g., breach, non-payment), and what happens to the user's data and installations upon termination.

Common mistake: No post-termination obligations on the user. Without a clause requiring deletion of copies, users can continue to run software they are no longer licensed to use.

In plain language: Identifies the jurisdiction whose law governs the agreement and specifies whether disputes go to arbitration, mediation, or court — and where.

Common mistake: Choosing a governing law jurisdiction with no connection to where the software is developed or the user base is located. Some jurisdictions — particularly US states with strong consumer-protection laws — apply local law regardless of a contractual choice-of-law clause.

In plain language: States that the EULA is the complete agreement between the parties, superseding prior representations, and that invalid clauses are severed rather than voiding the whole agreement.

Common mistake: Omitting a severability clause. If a court voids an overbroad restriction clause — which is common with non-circumvention or data-use provisions — the entire EULA can unravel without it.

A EULA is a legally binding contract between a software publisher and the person or organization using the software. It grants the user a limited right to install and use the software under defined conditions while reserving all intellectual property rights for the publisher. EULAs are distinct from a sale: you purchase a license to use the software, not ownership of the software itself. Nearly every commercial software product — desktop applications, mobile apps, and SaaS platforms — is governed by some form of EULA.

A EULA is generally enforceable when the user has adequate notice of its terms and affirmatively accepts them — typically via a click-wrap checkbox during installation or account creation. Courts in the US, UK, Canada, and the EU have upheld click-wrap EULAs as binding contracts. However, specific clauses may be voided if they are unconscionable, violate consumer-protection law, or fail formal requirements — such as all-caps warranty disclaimers under the UCC. Enforceability is jurisdiction-specific, so review by a local attorney is advisable before distributing in new markets.

A EULA governs the use of installed or downloaded software and focuses on license scope, IP ownership, and restrictions on copying or modifying the code. A Terms of Service (ToS) governs use of a website or online platform and typically addresses account conduct, content ownership, payment terms, and service availability. SaaS products often use both: a EULA for the software component and a ToS for the platform and account relationship. For most desktop or mobile applications, a EULA alone is sufficient.

A traditional wet signature is not required for most consumer and business EULAs. Click-wrap acceptance — clicking an 'I Agree' button or checking an acknowledgment box — constitutes a valid electronic signature in the US under the E-SIGN Act, in Canada under PIPEDA and provincial e-commerce laws, and in the EU under the eIDAS Regulation. For enterprise software licenses with significant commercial value, a separately executed order form or signed addendum is common practice to create a stronger paper trail.

At minimum, a EULA should cover: the license grant and scope, permitted and prohibited uses, intellectual property ownership, a warranty disclaimer in conspicuous text, a limitation of liability with a defined cap, data collection and privacy disclosures, term and termination conditions (including post-termination obligations), and governing law. Missing any of these leaves meaningful legal gaps — particularly the warranty disclaimer and liability cap, which are the primary mechanisms protecting the publisher from user claims.

In the US, reverse-engineering restrictions are generally enforceable under contract law, though the Computer Fraud and Abuse Act and DMCA provide additional statutory protections. In the EU, the Software Directive (2009/24/EC) grants users a statutory right to decompile software for interoperability purposes that cannot be contractually waived — meaning a blanket reverse-engineering prohibition is only partially enforceable for EU users. In Canada and the UK, enforceability is similarly limited for interoperability-related decompilation.

Apple's App Store and Google Play each require developers to agree to their standard developer agreements, which include baseline EULA terms. Apple provides a standard EULA template that applies if you do not supply a custom one. If you provide a custom EULA, it must comply with Apple's or Google's requirements and cannot conflict with their platform terms. Custom EULAs are recommended for any app that collects sensitive data, has significant commercial licensing terms, or restricts user rights beyond platform defaults.

A EULA can incorporate privacy disclosures and consent language, but it does not replace a standalone Privacy Policy or, where required, a Data Processing Agreement (DPA). Under GDPR, if your software processes personal data on behalf of business customers, a DPA is a separate mandatory document. The EULA should reference the Privacy Policy URL and confirm that use of the software constitutes consent to data collection as described — but the detailed rights and obligations under GDPR belong in dedicated privacy documentation.

A breach of the EULA typically triggers automatic termination of the license, requiring the user to stop using the software and delete all copies. The publisher may also seek injunctive relief to prevent ongoing misuse, and damages for any quantifiable harm. In practice, enforcement against individual consumers is rare due to cost, but EULA violations by businesses — particularly unauthorized redistribution or use to build a competing product — are pursued through cease-and-desist letters and, where justified, litigation.
