Users’ Files on a Chinese Office Platform’s Cloud Server Run the Risk of Censorship

Users' Files on a Chinese Office Platform's Cloud Server Run the Risk of Censorship

How would you react if you were blocked from accessing important documents stored on your personal cloud drive? A Chinese netizen, “Metoo just wants to make money” ( and referred to below as “Meetoo”), claims she was denied access to one of her own online documents by WPS Office, a Chinese cloud-based office platform, due to censorship. The document is a draft of a novel more than one million Chinese words in length. 

On July 11, 2022, “Metoo” posted the complaint about being locked out of WPS on the popular writer’s forum According to a screen capture of an auto-notification issued by WPS, “Metoo”‘s was denied access to her document because it contained illegal content.  Below is what she wrote on

WPS Office is a most popular mainland Chinese cloud office platform similar to Microsoft Cloud Office or Google Drive. It allows users to store documents in different formats, and share and co-edit them. “Metoo”‘s complaint captured netizens’ attention and her story was picked up by several social media outlets, and the hashtag “#WPS was exposed that it would delete users’ locally stored documents” (WPS ), has gone viral immediately as netizens used it to alert one and others. 

“Metoo” later told a local media outlet that the incident occurred in May. She told them she had never said that her locally stored document had been deleted, but further explained that it had been automatically synchronized to an older version of the document she had stored on the WPS p. After that, she could not access her own updated version. She stressed that in the process of her appeal, WPS had admitted that there was a loophole in the platform’s detection systems and promised to fix it.

Other WPS users, however, started sharing their experiences on social media. One student said that his term paper had disappeared from WPS. Another user said the same thing happened to his class presentation outline. And yet another claimed that he was once charged by WPS for recovering a document the platform had deleted.

In response, WPS denied that the platform would ever censor, lock or delete documents stored locally on the user’s computer. The company said:

However, it added that according to existing laws in China, including the Cyber Security Law, Measures on the Administration of Internet Information Services, and Provisions on Ecological Governance of Network Information Content, among others, all platforms which provide online information services are obliged to review contents that circulate on its platform. In light of these requirements, WPS said it seeks to protect users’ information security by encrypting sensitive content and providing a channel for its customers to appeal and get back their documents.  

A reporter from the Beijing News tested WPS’s censorship mechanism and found that once the user shared a document that contained sensitive content such as pornography or sensitive language with another user, the link would be redirected to a page with an access denial notification. The reporter explained that once the “share” button was pressed, the document would be synchronized with the cloud server, triggering automatic censorship. The reporter could not explain why “Metoo”s locally stored document was also affected.

Some tech bloggers pointed out that it was ridiculous for a cloud office platform to separate the concept of cloud files and local files because cloud storage and co-editing are the most important features of a cloud office platform. If users cannot co-edit a document with their colleagues and are required to download the document to their own machine after editing, there is no point in having a cloud drive. 

Many concluded that the censorship and privacy violation problem is not confined to WPS. No platforms or applications that synchronized with cloud servers could not be trusted, as they are obliged under Chinese laws to review and censor their users’ contents.
