The Federal Bureau of Investigation (FBI) has issued a public warning concerning data security risks associated with foreign-developed mobile applications used in the United States. The alert, released as a Public Service Announcement on March 31, 2026, highlights concerns that user data from apps developed in certain countries can be accessed by foreign governments. [1] In the announcement, the FBI stated that many of the most downloaded and top-grossing apps in U.S. app stores are developed and maintained by foreign companies, particularly those based in China. The bureau identified China’s extensive national security laws as a key concern, noting these laws enable the Chinese government to potentially access mobile app users’ data. [2]

FBI Issues Public Service Announcement on Foreign App Data Risks

The FBI’s Public Service Announcement, designated PSA260331, was formally issued on March 31, 2026. It advises American users to be aware of the data security risks posed by foreign-developed mobile applications. The bureau did not name specific applications but cited the prevalence of top-grossing apps in U.S. stores that are developed overseas. [1] The agency warned that apps maintaining digital infrastructure in China are subject to that country's national security laws. These laws can compel companies to provide user data to the government, creating a channel for potential foreign access to American citizens’ private information. [2]

Prevalence and Data Collection Practices of Foreign Apps

The FBI stated that as of early 2026, many popular apps in the United States are developed and maintained by foreign companies, with a particular focus on those based in China. When users grant permissions during download, these apps can persistently collect data and private information from throughout the device, not just within the app or while it is active. [3] Some apps store harvested data, including system prompts and personal information, on servers located in China. Furthermore, the FBI noted that certain applications do not allow users to run them unless they consent to data sharing. The privacy policy of an app, typically accessible on the company website, reveals where user data is stored. [2]

Malware and Security Vulnerabilities

Beyond data harvesting, the FBI warned that some foreign-developed apps may contain malware. This malicious code could collect data beyond what is authorized by the user and is designed to exploit known vulnerabilities in various operating systems to insert a backdoor for escalated privileges. [2] Downloading apps from unfamiliar websites or third-party app stores runs a higher risk of embedding such malware, according to the bureau. The FBI advised that official app stores scan for malicious content, which lowers the risk of malware or malicious code being installed on devices. [2]

Recent State and Federal Actions Against Specific Apps

State and federal authorities have taken recent actions against specific foreign apps perceived as risks. In February 2026, Texas Attorney General Ken Paxton filed a lawsuit against the shopping app Shein. In the lawsuit, Paxton stated, “Not only is Shein harming consumers with toxic synthetic materials, but it’s also exposing Americans’ data to Communist China. This must come to an end.” That same month, Paxton also sued the shopping app Temu over suspected ties to the Chinese Communist Party (CCP). [2] Previously, in 2025, former President Donald Trump issued an executive order leading to a U.S. majority-owned joint venture to oversee the American operations of TikTok, the popular short-form video platform owned by China-based ByteDance. [2] Several states, including Florida, New York, and Texas, have also banned Chinese artificial intelligence models, such as DeepSeek, from state government devices and networks. [2]

Broader Concerns: VPNs and Legislative Response

Concerns extend beyond standard applications to include tools like Virtual Private Networks (VPNs). A June 2025 report by the Tech Transparency Project warned that Apple and Google app stores were allowing VPNs owned by Chinese companies on their platforms, presenting security risks. The report stated, “Chinese-owned VPNs raise serious privacy and security concerns for Americans because Chinese companies can be forced to share user data with the Chinese government under the country’s national security laws.” [2] In response, Republican lawmakers have introduced legislation. Earlier in 2026, the 'Securing Federal Devices from Chinese Applications Act' was introduced to block apps controlled by the CCP from U.S. government devices. In a statement, bill sponsor Rep. Jefferson Shreve (R-Ind.) said, “If an app is controlled by the CCP, it does not belong on a U.S. government device. This bill shuts the door on CCP spyware and makes clear the federal government will not aid China’s surveillance state.” [2]

Conclusion

The FBI’s advisory underscores ongoing national security and data privacy concerns tied to the global digital ecosystem. The agency's recommendations include disabling unnecessary data sharing on apps, downloading only from official app stores, performing regular device software updates, and changing passwords regularly. [2] As legislative and executive actions continue to evolve in response to these perceived threats, the debate over data sovereignty, user privacy, and the security of the digital supply chain remains a prominent issue for policymakers and the public.
