On 27 February 2013, the Article 29 Working Party (hereinafter “Article 29 WP”) adopted its newest Opinion WP 202 (hereinafter “Opinion”) regarding apps on smart devices. This article summarizes some of the most important statements and guidelines provided by the European data protection authorities.
Applicable law
First of all, the Opinion emphasizes that the Data Protection Directive (95/46/EC) and the ePrivacy Directive (2002/58/EC, as revised by 2009/136/EC) constitute the relevant EU legal framework for the processing of personal data via apps on smart devices and that both directives are imperative laws which cannot be excluded by contractual agreement.
Four main parties
Hereafter, the Opinion identifies four main parties which, depending on the purposes and means of the respective data processing activity, carry different responsibilities:
1. App developers
According to the Opinion, app developers decide the extent to which apps access and process personal data in the device and insofar have to be regarded as data controllers. Their responsibilities can be limited though, if no personal data are processed and/or made available outside the device.
2. OS and device manufacturers
Operating system (OS) and device manufacturers are considered as (joint) data controllers for personal data which are processed for the manufacturers’ purposes, such as the smooth running of the device or security issues.
3. App stores
App stores are likely to be regarded as data controllers for personal data of users (such as their name, address of financial data) that are processed, when the users are purchasing apps.
4. Third parties
There are various third parties involved in the processing of data through the use of apps, e. g. advertising networks or analytics providers. The Opinion distinguishes between two roles of third parties: one is to execute operations for the app owner. In that case, when acting exclusively on behalf of the app developer, the third party is likely to be operating as data processor. The second role is to collect information via apps and processing this information for own purposes. According to the Opinion, in that case the third party acts as data controller.
Legal ground
The Opinion then examines the legal grounds for handling data in connection with apps. It hereby distinguishes between two main stages of data processing:
1. Prior to installation
According to the Opinion, the user’s consent pursuant to Article 5 (3) of the ePrivacy Directive must be obtained, before information may be placed on and/or retrieved from the user’s device. The Opinion points out that this consent refers to any information on the device and has to be obeyed by every service offered “in the Community“, regardless of the location of the service provider.
In addition, if personal data (e. g. contacts in the address book or pictures) shall be processed before or during the installation of an app, it must also be ensured that the user gives his or her consent pursuant to Art. 2 lit h) of the directive 95/46/EC.
The Opinion points out that both consent requirements are simultaneously applicable and subject to the conditions of having to be free, specific and informed.
2. During usage of the app
When it comes to the usage of the app itself, the legal ground for the processing of personal data may change and either be based on consent or on other forms such as the necessity for the performance of a contract with the data subject (Article 7 lit b)) or the necessity for legitimate interests (Article 7 lit f) of the directive 95/46/EC).
Other topics covered by the Opinion
In addition to the above, the Opinion also examines other relevant topics regarding the processing of data through apps. This includes an analysis of the fundamental principles of purpose limitation and data minimisation, a review of the security requirements and information obligations and a discussion on the data subject’s rights, the retention periods and the specific safeguards that must taken for the protection of children.
Guidelines and information
At the end, the Opinion provides various conclusions and recommendations for each main party. The most important ones are the following:
App Developers must
- Ask for consent before the app starts to retrieve or place information;
- Ask for granular consent for each type of data the app will access and allow users to revoke their consent;
- Be aware that consent does not legitimise excessive or disproportionate data processing;
- Provide a readable, understandable and easily accessible privacy policy.
OS and device manufacturers must
- Update their APIs (application programming interface) and store rules to offer users sufficient control to exercise valid consent over the data processed by apps;
- Implement consent collection mechanisms in their OS at the first launch of the app or the first time the app attempts to access personal data;
- Employ privacy by design principles and ensure the default settings of pre-installed apps are compliant with European data protection law;
- Provide (by default) user-friendly and effective means to avoid being tracked by third parties;
- Ensure the availability of appropriate mechanisms to inform and educate the end user before the app installation.
App stores must
- Comply with their obligations as data controllers when they process personal data;
- Enforce the information obligation of the app developer, including the types of data the app is able to access and for what purposes;
- Provide detailed information on the app submission checks they perform.
Third parties must
- Comply with the consent requirement determined in Article 5 (3) of the ePrivacy Directive when they read or write data on mobile devices;
- Not circumvent any mechanism designed to avoid tracking;
- When acting as advertising parties, avoid delivering ads outside the context of the app.
Of course this overview can only draw the attention to some of the relevant statements, which the Article 29 WP issued in the Opinion. From a practical point of view, one has to keep in mind that the national authorities generally conform to these European inputs and adopt them within their own field of activity.


Facebook subject to Irish, not German, data protection law, says German Higher Administrative Court
Datonomy readers may have had to grapple with the tricky issue of which national data protection law to apply in the context of an online service with a cross border dimension. They are not alone – the German courts have recently considered the issue in relation to Facebook’s operations.
In April, the German Higher Administrative Court of Schleswig-Holstein ruled that German data protection law does not apply to Facebook’s collection and processing of personal data of users in Germany. Instead only Irish data protection law would be applicable.
The case
The Internet giant faced an order by the Independent Data Protection Authority of Schleswig-Holstein, which wanted to force Facebook to allow German users the use of pseudonyms for the registration and for their profile names instead of the real name. German data protection law obliges website providers to enable this feature to the extent that this is technically possible and reasonable.
The decision
According to the Higher Administrative Court, German data protection law is however not applicable here, as it is Facebook’s Irish affiliate, Facebook Ireland Ltd., that is to be regarded as the relevant establishment for the processing of personal data of users in Germany, regarding the registration and the management of their accounts.
According to article 4 (1) a) of the directive 95/46 EC, only the data protection law of that Member State is applicable, where the establishment of a controller, which carries out the relevant processing of personal data in the context of its activities, is located.
The court furthermore stated that Facebook’s German subsidiary in Hamburg, Facebook Germany GmbH, would exclusively operate in the fields of marketing and advert acquisition without having any actual influence on the German user accounts.
Since the requirements of article 4 (1) a) of the directive 95/46/EC were fulfilled by Facebook Ireland Ltd. and its processing of personal data of German users, the court consequently did not examine the question, if German data protection law could be applied pursuant to article 4 (1) c) of the directive 95/46/EC, as both provisions are mutually exclusive.
The Higher Administrative Court completed its ruling with an additional statements saying that German data protection law would only insufficiently implement article 4 (1) a) of the directive 95/46/EC. The Higher Administrative Court further emphasised that if personal data is processed by an establishment that is not located in a EU/EEA member state, article 4 (1) c) of the directive 95/46/EC applies and determines the applicable national law.
Finding the applicable law
It is important to highlight that finding the applicable law under article 4 (1) of the directive 95/46/EC is anything but easy. The directive provides two distinctive situations, in which the national data protection law of a member state will apply:
National data protection authorities in the EU take however different approaches when determining the meaning of the term “equipment”. While cookies or other software that are placed on a user’s PC or smart phone, are widely recognized as equipment, different views are taken when it comes to other scenarios. The Article 29 Working Party, for example, interprets the term equipment in a rather broad way stating that also the activities of a processor in a member state could constitute a “making use of equipment”. Other data protection authorities believe that a non-relevant establishment of a controller can be seen as equipment.
Conclusion and comment
In each case, the determination of the applicable national data protection law regime depends on how personal data are processed and on the particularities of the relevant establishment that is responsible for the processing. Since different national rules impose different rights and obligations on the data controller regarding the processing of personal data, companies should structure their data processing activities thoroughly in order to avoid legal uncertainties.
The Working Party sought to bring some clarity and consistency of interpretation to this difficult area in its 2010 Opinion here. Datonomy and its colleagues at Olswang commented on the Opinion here and here. Could applicable law conundrums become a thing of the past for companies with multinational operations? That is certainly one of the drivers behind the draft General Data Protection Regulation, which seeks to harmonise substantive data protection rules across Europe, and introduce “one stop” regulation by the Member State where the organisation is headquartered. In practice, will differences over substantive rules and local enforcement approaches ever be eradicated? Datonomy readers will have to wait and see!
