A developer may publish an application in an app store, provide a link to a license agreement, and consider the legal side complete. However, the mere existence of an EULA does not mean that its provisions are suitable for the product or have become binding on the user.
What matters is how the software is distributed, when the user accepts the terms, and what the product actually does. A simple utility, corporate desktop software, a mobile game, and a subscription-based application require different rules. A template document may prohibit actions without which the software cannot function or fail to address paid content, family access, and updates. EULA stands for End User License Agreement. It governs the end user’s right to install and use the software while the developer or another rights holder retains the exclusive rights.
A separate license agreement generally makes sense when the user receives a copy of the software on their device. This applies to mobile applications, desktop software, games, browser extensions, and certain enterprise solutions.
For browser-based SaaS, a separate EULA is required less often. The user does not receive a copy of the server-side software, and access to its functionality can be governed by Terms of Use or a SaaS Agreement. If the SaaS includes a mobile client, installable module, or desktop version, license provisions may apply to that part of the product. The choice of document depends on the distribution model:
| Product Model | Is a Separate EULA Required? | What Should Be Regulated |
| Mobile or desktop application | Usually required | Installation, devices, accounts, updates, and usage restrictions |
| App Store application using Apple’s standard EULA | Depends on the product’s functionality | Check whether the standard terms are sufficient for the monetization model and functionality |
| Browser-based SaaS without an installable component | Terms of Use or a SaaS Agreement are usually sufficient | Access to the service, accounts, payments, data, and acceptable use |
| SaaS with a mobile or desktop client | Often required for the installable component | Separate the application license from the terms governing the cloud service |
| Enterprise on-premise solution | A B2B license agreement is required | Servers, users, instances, test environments, and support |
| White-label or OEM product | A standard EULA is not sufficient | The partner’s rights to distribute, brand, and provide the product to end users |
An EULA is intended for the end user. If a company grants a partner the right to distribute the product, integrate it into another solution, or provide it under the partner’s own brand, a separate B2B agreement is required. An end-user license does not grant the partner such rights.
Apple applies its standard EULA if the developer does not provide a custom license agreement. It applies to the application in all countries and regions, covers use on Apple devices, and reserves to the developer all rights not expressly granted to the user.
For a simple application, the standard wording may be sufficient. It contains a basic license and provisions relating to support, warranties, claims, and intellectual property. However, the standard EULA does not take into account how a particular product actually works.
A custom agreement may be required if the application uses a complex subscription model, provides digital content, includes virtual goods, permits professional use, or establishes specific rules for accounts and user-generated content. A Custom EULA must comply with Apple’s minimum requirements and must not conflict with the platform’s usage rules.
Publishing an application in an app store should not be treated as a substitute for contractual arrangements. The app store terms govern the user’s relationship with the platform, while the developer needs to establish its own rules for use of the product. This is particularly important if the application is distributed through several platforms or is available for direct download.
The document should be structured around the actual user journey. Provisions governing the license, payments, and termination of access should correspond to the interface, account settings, and application description in the app store.
An EULA defines the devices on which and purposes for which the software may be used. The license is usually limited, non-exclusive, and non-transferable, but these terms alone are not sufficient.
It is necessary to establish whether the user may connect multiple devices, provide access to family members, or transfer the software after replacing a phone. For a professional product, commercial use should be addressed separately. A “personal use only” restriction may inadvertently prohibit the very use case for which the user purchased the software.
If functionality is linked to an account, the EULA should be consistent with the account rules. Password sharing, account sales, and circumvention of device limits may be prohibited. At the same time, technical platform features may permit family or group access. Contractual restrictions should not conflict with the product settings or app store rules; otherwise, users may receive contradictory instructions.
The agreement should specify whether the license covers updates and whether the developer may discontinue support for older versions. If an up-to-date operating system is required for the software to function, this should be reflected in the documentation and user communications. The right to update an application does not allow the developer to change the core characteristics of a paid product without restriction. Users in the EU are protected by mandatory requirements concerning the conformity of digital content and digital services. An EULA cannot exclude consumer remedies established by law.
Subscriptions, virtual currency, in-game items, and paid content require more precise terms. The user should understand exactly what they are purchasing, how long access is provided, and what happens after a subscription is canceled or an account is suspended. If a digital item cannot be withdrawn from the application, transferred to another person, or exchanged for money, this should be stated expressly. The EULA terms should also be consistent with the information displayed on the purchase screen and the rules of the relevant platform.
The developer may prohibit unauthorized copying, distribution, circumvention of technical measures, and interference with the operation of the software. For games and platform-based products, automated data collection, use of bots, fraudulent activity, and exploitation of vulnerabilities may also be regulated.
A template prohibition on any modification, examination, or decompilation may be too broad. EU law permits certain actions necessary for the normal use of software, the creation of backup copies, and interoperability. An EULA should take applicable law into account rather than purport to grant the rights holder an absolute prohibition that cannot be enforced.
If users upload photographs, text, music, code, or other materials, a license governing the software alone is not sufficient. The document should specify what rights the developer receives to store, process, display, and transmit such content.
The permission should correspond to the product’s functionality. A photo-editing application may need the right to process a file and save the result, but not a perpetual license to use the image commercially in the developer’s advertising.
The EULA should describe the violations that allow the developer to restrict use of the software. The grounds should be specific: circumvention of payment, interference with security, illegal content, or a material breach of the terms.
Immediate suspension may be appropriate in dangerous situations, but not for every technical error made by a user. For paid products, refunds, the remaining subscription period, access to user data, and mandatory consumer rights should also be taken into account.
A link in the website footer or on an app store page does not always prove that the user saw and agreed to the terms. The developer needs to establish a clear point at which the agreement is concluded.
The most reliable approach is to display a link to the EULA before registration, initial installation, or payment and obtain the user’s active consent. The interface should allow the user to open the document before clicking the acceptance button. A pre-selected checkbox or wording hidden among other interface elements weakens the company’s ability to prove consent.
The system should retain:
For applications without registration, acceptance may be linked to a technical identifier or stored locally if this method complies with personal data requirements. The appropriate solution depends on the architecture and the jurisdictions in which users are located.
A clause stating that “the developer may amend the EULA at any time” does not guarantee that new terms will automatically become binding on existing users. It is particularly risky to introduce new charges, expand rights to user-generated content, or substantially reduce available functionality in this way.
The company should retain previous versions of the document, specify the effective date of amendments, and notify users in advance. For material changes, it is advisable to obtain renewed active consent. Technical corrections and clarifications may be introduced through a notice if permitted by the agreement and applicable law.
It is also necessary to determine in advance what happens if a user refuses to accept the new version. The user may be given a period to complete their activities and export their data. Immediate suspension without an opportunity to retrieve their own information creates additional risk.
An EULA governs the license for installable software. Terms of Use establish the rules for using the service, accounts, user-generated content, and paid features. A Privacy Policy explains the processing of personal data, while a Cookie Policy covers the use of cookies and similar technologies.
An EULA and Terms of Use may be combined into a single document if the structure remains clear. For a product with a simple model, this reduces the number of consents and simplifies updates. A complex platform may require a separate set of documents, with each document governing a specific part of the relationship.
The key requirement for such a system is consistency. The EULA should not promise indefinite access if the Terms of Use allow the account to be terminated immediately, and the subscription description in the app store should not conflict with the refund rules in the application.
The first mistake is copying another product’s agreement. The document may refer to features that the application does not have, use an unsuitable payment model, or impose restrictions that conflict with the interface.
The second problem concerns ownership of rights. An EULA may be published on behalf of a company to which developers or contractors have not transferred the rights to the code. Such a company cannot grant users a license to the extent stated in the agreement.
The third mistake concerns acceptance of the terms. The user may only learn about the document after making a payment, or the agreement may only be available through a link that cannot be opened before registration. In the event of a dispute, it will be difficult for the developer to prove which version was accepted.
Finally, excessive restrictions may conflict with mandatory legal provisions. A complete disclaimer of liability, exclusion of all warranties, and prohibition of methods of using the software permitted by law do not become valid merely because the user clicked an acceptance button.
The developer should compare the agreement with the actual method of distributing the product, the app store rules, and the interface used to accept the terms. Subscriptions, digital content, user-generated materials, updates, and the consequences of account suspension should be reviewed separately.
It is also necessary to confirm that the company owns the rights to the code, design, and other elements included in the application. Licenses for open-source components, SDKs, fonts, and third-party content may impose additional obligations.
The final check should be performed within the product itself: users should see the current version of the EULA, be able to open it before acceptance, and retain access to the document after registration.
Wolja Digital reviews the application’s contractual model and determines whether a separate EULA is required or whether the licensing provisions would be better included in the Terms of Use or another document.
We align the terms with the interface, monetization model, App Store and Google Play rules, and establish the legal framework for accepting and updating the agreement. We also separately verify ownership of the software rights and the restrictions that the company may lawfully impose on users.
