noyb Complaints
noyb complaints are formal privacy complaints filed by noyb, an Austrian-based advocacy group, with European data protection authorities against organizations it believes are breaking EU privacy rules. Many of these complaints target cookie banners, consent practices, and cross-border transfers of personal data. Filing a complaint asks a regulator to investigate; it does not by itself determine that a company has broken the law.
The term refers to complaints lodged by noyb (also styled NOYB, from 'None of Your Business'), an Austria-based non-governmental organization, with supervisory authorities under the GDPR and, in cookie-related matters, provisions implementing the ePrivacy Directive. Complaints are typically filed on behalf of an individual data subject with a national data protection authority, and may allege defects in cookie banner design and consent collection, absence of a valid legal basis for processing, or unlawful international data transfers. According to the evidence, noyb complaints have addressed cookie banners (a complaint lodged with the Austrian DPA that the EDPB required the Belgian DPA to handle on the merits), consent validity for online services (for example, a complaint against dict.cc concerning whether one-click consent can be 'freely given' and 'informed'), the legitimate interest and permission basis in a complaint concerning Meta's AI processing, and data transfers to China in six complaints filed across Greece, the Netherlands, Belgium, Italy, and Austria against firms including AliExpress, TikTok, and WeChat. A complaint initiates a regulatory process before the competent authority; the outcome, including any finding of infringement or corrective measures, depends on that authority's assessment and any subsequent appeal or cross-border cooperation procedures. The scope, procedure, and enforcement consequences vary by jurisdiction and by the legal regime invoked, and this entry does not address the merits or final disposition of any particular complaint.
Why it matters
For organizations operating in the EU, noyb complaints are one of the more visible drivers of regulatory scrutiny around cookie banners, consent design, and cross-border data flows. Because noyb systematically targets common consent practices, its complaints can turn a design choice that many companies share into the subject of a formal investigation by a supervisory authority. A complaint does not itself establish that a company has broken the law, but it obliges the competent authority to consider the matter, and the resulting decisions can influence how similar practices are assessed across the market.
