STOCKHOLM, July 17 (Reuters) - Austrian advocacy group

noyb filed data privacy complaints against China's AliExpress,

TikTok and WeChat on Thursday, saying they failed to comply with

European Union laws on providing users with a full copy of their

data.

While most tech companies have a tool to fulfil requests for

downloading user information, some Chinese companies have made

it difficult to access the information, noyb said.

"TikTok, AliExpress and WeChat love collecting as much data

about you as possible but vehemently refuse to give you full

access as required by EU law," said Kleanthi Sardeli, data

protection lawyer at noyb.

A spokesperson for Tencent ( TCTZF ), owner of WeChat, said

the company complies with regulations in the markets it operates

and is committed to protecting user privacy and data security.

TikTok and AliExpress did not respond to requests for

comment.

Noyb is known for filing complaints against American

companies such as Apple ( AAPL ), Alphabet and Meta

, leading to several investigations and billions of

dollars in fines.

In January noyb filed complaints against six Chinese

companies and sought to suspend data transfers to China and

called for fines that can reach up to 4% of a company's global

revenue.
