Taiwan Raises Alarm: Chinese Apps Like TikTok and WeChat Pose Serious Data Security Risks

Have you ever wondered what really happens to your personal data when you use popular Chinese apps like TikTok, WeChat, or Baidu Cloud? If you’re in Taiwan—or just care about privacy in an increasingly digital world—you’re not alone. The Taiwanese government has sounded a loud alarm, warning its citizens: the risks may be far greater, and more immediate, than most people realize.

In July 2024, Taiwan’s National Security Bureau (NSB) issued a stark warning after investigating some of the most widely used Chinese-developed mobile apps. Their findings? Significant data security and privacy violations that could expose countless users to potential cyber-espionage, identity theft, and government surveillance.

Let’s break down what you need to know, why it matters, and how you can protect yourself in a world where data is the new currency—and, increasingly, a target.

Why Is Taiwan Warning About Chinese Apps? Understanding the Real Risks

Imagine if every time you sent a message or scrolled through your social feed, someone was silently taking notes behind the scenes. That’s essentially what Taiwan’s NSB says is happening with certain Chinese-made apps.

The NSB’s Alarming Findings

In a recent round of random inspections, the NSB scrutinized five Chinese apps that are household names in Taiwan: – Rednote – Weibo – TikTok – WeChat – Baidu Cloud

They evaluated these apps across 15 security indicators, grouped into five main categories:
1. Personal data collection
2. Excessive permission usage
3. System information extraction
4. Biometric data access
5. Network transmission patterns

The verdict? All five apps failed spectacularly. Each one was found to excessively collect, transmit, and store vast amounts of sensitive user data—often without explicit user consent.

What Kind of Data Are These Apps Collecting?

If you’re picturing just your basic profile info, think again. Here’s a snapshot of the data points flagged by investigators:

Facial recognition data: Apps accessed and sometimes stored users’ facial features.
Screenshots and clipboard contents: Some apps could grab what you copy or save on your device.
Contact lists and location: Your friends and your whereabouts are at risk.
System information: Apps harvested details about your device, installed applications, and more.

Worse still, all these apps sent data packets back to servers located in China. In the context of China’s laws on data sharing, that’s a huge red flag.

How Chinese Law Drives Data Risks Abroad

Here’s where things get even more concerning: under China’s Cybersecurity Law, all Chinese enterprises must comply with requests from Chinese authorities for data access—particularly when it relates to national security or intelligence. That means that if you’re using a Chinese-developed app, your personal data could be legally requisitioned by the Chinese government.

The National Intelligence Law

In addition to the Cybersecurity Law, the National Intelligence Law compels organizations and individuals to support and cooperate with state intelligence efforts. This law further erodes any hope of privacy for users outside China, such as in Taiwan or the West.

Bottom line: Data collected by Chinese apps isn’t just sitting idle—it can, and sometimes must, be handed over to government agencies upon request.

Real-World Implications: Why You Should Care

You might be thinking, “I have nothing to hide. Why should I care if an app knows my contacts or my selfie habits?” Here’s why that matters:

1. Espionage and Surveillance

Data from apps can provide a detailed snapshot of individuals, organizations, and even entire populations. In tense geopolitical environments (like cross-strait relations between China and Taiwan), such data can be weaponized for: – Political surveillance – Influence campaigns – Targeted misinformation

2. Identity Theft and Fraud

The more data apps collect—especially sensitive data like biometric information—the greater the risk of identity theft, account takeovers, or even blackmail.

3. Loss of Digital Autonomy

When foreign governments have access to your data, your right to privacy is compromised. You lose control over where your information goes, how it’s used, and who sees it.

4. National Security Risks

For government officials, journalists, and activists, using these apps could endanger not just personal privacy, but collective safety.

How Do Chinese Apps Collect So Much Data? Let’s Peek Behind the Curtain

Modern apps need certain permissions to function properly, but excessive or unnecessary data harvesting goes well beyond what’s needed for user experience.

Common Permission Abuses Identified

According to the NSB, these Chinese apps requested or accessed permissions such as: – Accessing your camera and microphone (sometimes without active use) – Reading your SMS and call history – Viewing your clipboard (anything you’ve copied or pasted) – Constantly tracking your location – Reading installed app lists (to profile your interests or habits)

Let me explain with an analogy:
Imagine inviting a plumber to fix a leaky faucet—but when you’re not looking, they start photographing your entire house, copying your address book, and mailing all this info to a third party. That’s the scale of overreach Taiwan’s investigators found.

Not Just a Taiwan Problem: The Global Backlash Against Chinese Apps

If this sounds eerily familiar, it’s not just you. Over the past few years, governments around the world have grown increasingly wary of Chinese tech giants and their software.

TikTok: The Poster Child for Data Concerns

United States: In 2024, US Congress passed a law to ban TikTok nationwide unless its Chinese owner, ByteDance, divests. While the ban’s enforcement has been delayed, the signal is clear: Washington sees TikTok as a national security threat.
United Kingdom, Canada, EU: These regions have all banned TikTok from government devices, citing data security risks and possible espionage.
India: India went a step further, permanently banning dozens of Chinese apps, including TikTok and WeChat, back in 2020 (source).

Why the Focus on TikTok, WeChat, and Similar Apps?

Massive user base—hundreds of millions of users globally
Deep integration into daily life—from messaging to payments to entertainment
Opaque data practices—lack of transparency on where and how data is stored

The consensus among security experts? Chinese apps, especially those with close ties to Beijing, pose unique risks that can’t be ignored.

What Can You Do? Protecting Your Privacy in the Age of Surveillance Apps

The good news: you’re not powerless. While governments debate bans and regulations, there are practical steps you can take today to safeguard your digital life.

1. Be Critical With App Permissions

Only grant permissions that are absolutely necessary for the app to function.
Revoke permissions that feel invasive (like constant access to your location or contacts).

2. Do Your Research Before Downloading

Check where the app’s parent company is based.
Read independent reviews and privacy reports (look for red flags like unexplained data transmissions).

3. Regularly Audit Your Installed Apps

Uninstall any apps you no longer use.
Review privacy settings in your device’s app manager.

4. Use App Alternatives Where Possible

For Chinese social media, consider Western alternatives with better transparency.
For file storage, opt for providers with clear privacy policies and data localization.

5. Stay Informed

Follow reputable tech media outlets (The Verge, TechCrunch) and government cybersecurity advisories.
Bookmark your local data protection authority’s website for updates.

Taiwan’s Official Guidance: What the NSB Recommends

The NSB’s message is clear: exercise caution. Here’s their official advice, distilled:

Avoid installing Chinese-developed apps with known security risks.
If you must use them, limit what personal information you share.
Regularly update apps and your operating system to patch vulnerabilities.
Seek out apps that comply with international privacy standards and have transparent data practices.

By following this guidance, you not only protect your own privacy—you help raise the collective standard for digital security.
