The non-profit organization in Austria has filed a complaint against eight technology companies, including Apple and Amazon, saying they do not comply with the European data protection system.
The move, taken by the organization led by privacy activist Max Schreems, also included Netflix, Sputevae and YouTube after testing them by asking for proprietary data from their users, Reuters reported on Saturday.
"No service has been committed," Nuweib said in a statement.
The European data protection system, implemented in May, gives users the right to access their data, information about sources and recipients.
Social networks must have European approval every time you want to use their data in new formats, including in ad-targeted advertising.
In response to the complaint, Amazon said it has developed a privacy help page that shows customers how they can manage their information on all platforms.
"We are committed to any request from a data platform to allow it to access data managed by Amazon."
"We are committed to the implementation of all domestic and international laws and regulations, including the European General Data Protection System, which we believe we are fully committed to," said a spokeswoman for Sputivay.
Nueb said she had filed complaints with Austrian authorities on behalf of 10 users, and Austria's regulator would have to work with its counterparts in the main broadcast services.
"Many services have established systems to respond to requests for access, but they often do not provide the data that the user is entitled to access even remotely, and this leads to structural violations of user rights," he said.
