Investigation Exposes App Stores’ “Implicit Endorsement”

On April 16, 2026, Tech Transparency Project (TTP), an organization monitoring technology transparency, released shocking findings. The investigation revealed that major app stores, Google Play and Apple App Store, used by billions worldwide, not only host so-called “nudify apps” but also actively recommend them to users through their algorithms. These apps are deepfake applications that misuse AI technology to inappropriately alter images of people (especially women), making them appear as if their clothes have been removed. The problem lies in the fact that these apps circulate under disguised harmless categories like “entertainment” or “photo editing,” easily appearing in store search results and related recommendations. TTP’s report pointed out that Apple’s “App Store search function directly promotes nudify apps,” and Google is reportedly facing similar issues. This investigation highlights how major tech platforms are either unaware or irresponsible in allowing the spread of harmful and ethically problematic content, once again drawing severe criticism toward the tech industry.

What Are Nudify Apps? The AI Technology Behind Them

The technological foundation of nudify apps primarily lies in Generative AI and Deepfake technology. These apps analyze user-uploaded images of people (especially photos in swimwear or everyday clothes) and use machine learning models to generate images depicting a “state of undress.” Technically, the process involves detecting clothing areas in the image and filling them with skin texture, with the generated images often reaching a level indistinguishable from reality. Originally developed for film production and educational purposes, deepfake technology has long been warned about its potential for misuse. Nudify apps are a prime example, posing a high risk of being used for privacy violations, bullying, and sexual harassment, primarily targeting women. TTP’s investigation also reported that these apps often employ deceptive business models, advertising “free trials” while actually requiring expensive subscriptions. Furthermore, it remains unclear how the image data collected by these apps is used and where it goes, posing risks of data leaks and secondary misuse.

The Algorithm’s “Unwitting Complicity”: Why Are They Recommended?

The core of the issue lies in the curation and recommendation algorithms of the app stores. TTP’s tests showed that searching for common keywords like “AI photo editor” or “body editor” on the Apple App Store frequently displayed nudify apps in top results. These apps also inadvertently appeared in Apple’s “Today” tab and “Games” section recommendations. Google Play exhibited similar behavior, with search autocomplete and “similar apps” features serving as pathways to nudify apps. This stems from the app stores’ adoption of algorithms that prioritize “engagement” and “download numbers.” Because nudify apps contain inappropriate content that piques user curiosity, they tend to have high click-through rates and dwell times, leading algorithms to mistakenly判定 them as “popular.” Consequently, a structure has been created where harmful apps spread unintentionally through the platforms. Apple has long claimed that “the App Store provides a safe ecosystem,” but this investigation suggests that claim is showing cracks.

Impact: From Privacy Violations to Loss of Social Trust

The impact of this problem is immeasurable. First, individual privacy and dignity are severely violated. As nudify apps inappropriately alter images without consent, victims are likely to suffer psychological damage. This is especially prevalent when images posted on social media are used without authorization, reducing victims to “sexual objects” against their will. Second, trust in the entire technology industry is eroded. Major platforms tolerating or recommending harmful content gives users the impression that the environment is “unsafe,” which could ultimately lead to user attrition in the long term. Furthermore, regulatory intervention is accelerating. Moves to regulate deepfakes are already underway in Europe and the United States, and these findings will likely spur lawsuits and legislation holding app stores accountable. For instance, some U.S. states already have laws criminalizing the creation and distribution of non-consensual deepfake pornography.

Responses from Both Companies and Industry Reactions

Following the release of TTP’s report, Google and Apple issued separate statements. Apple stated, “The App Store does not permit harmful content. Apps that violate our guidelines are removed promptly,” and mentioned they are investigating the apps cited in the report. Google also stated, “Apps that violate our policies are removed upon detection.” However, both companies tended to avoid detailed explanations of why their algorithms recommended these apps. Voices from the industry are calling for “platform accountability.” App stores are not mere marketplaces but act as content “gatekeepers.” Therefore, there is a demand not only for automated systems but also for enhanced manual review processes. On the other hand, some app developers argue that “excessive regulation hinders innovation,” but clarifying ethical boundaries is urgently needed.

Outlook on Technical and Legal Countermeasures: What Should Be Done?

Addressing this issue in the future requires a multi-faceted approach. Technologically, the development of AI detection technology is key. For instance, app stores could introduce AI review systems that automatically analyze app functionality to identify inappropriate content generation. On the user side, research is also underway on technologies like embedding invisible watermarks in images to prevent unauthorized alteration. Legally, harmonizing global regulations is a challenge. The European Union’s (EU) AI Act proposal is discussing classifying deepfake apps as “high-risk” and imposing strict transparency obligations. In Japan, the “Act on the Protection of Personal Information in the AI Era,” enacted in 2025, expanded frameworks to regulate the misuse of image data, but it does not yet explicitly codify the responsibilities of app stores. In the future, legal moves to impose a “duty of care” on app store operators are likely to expand.

Conclusion: Redefining Tech Ethics

TTP’s investigation does more than just point out flaws in app stores; it raises fundamental questions about technology and ethics. How can we incorporate designs that protect human dignity without blindly trusting algorithm efficiency? Platforms need to be restructured not just as profit-driven entities but as responsible societal actors. It is also crucial for individual users to be aware of the background of the apps they download and to take an active stance in reporting problems. The nudify app issue is a mirror reflecting the “dark side” of the AI era. If left unchecked, it risks the collapse of trust in technology. Now is the time for the industry, regulators, and civil society to collaborate and build a healthy digital ecosystem.

FAQ

Q: What specific risks do nudify apps pose to users? A: Nudify apps primarily pose a risk of privacy violation by inappropriately altering images of others without consent. The generated images can be misused for bullying, sexual harassment, and defamation, causing psychological harm to victims. Additionally, there is a risk that image data collected by the apps could be leaked to third parties, leading to further secondary harm.

Q: What specific measures are Google and Apple taking to address this issue? A: Both companies prohibit harmful apps under their official policies and are proceeding with the removal of violating apps. However, TTP’s investigation pointed out that improving search algorithms and recommendation systems remains a challenge. It is believed they are considering strengthening review processes and introducing AI-powered automatic detection technology for inappropriate content, but details have not been made public.

Q: As an average user, how can I avoid becoming a victim of nudify apps? A: First and foremost, do not download apps from untrustworthy sources. Before installing an app, check its reviews and ratings, and research the developer’s information. Additionally, if possible, subtly altering photos (e.g., making slight changes) before posting them on social media can help prevent unauthorized use. If you notice a problem, report it to the app store promptly.
