AI Romance Apps Reportedly Compromise User Privacy for Data Harvesting

AI-powered romantic chatbots, marketed for enhancing mental health, are found to exploit user privacy by harvesting sensitive personal information for data sharing and targeted ads, with inadequate security measures and consent protocols, according to research by the Mozilla Foundation.

Risk classification

• Primary risk domain: 2 Privacy & Security
• Primary risk subdomain: 2.1 Compromise of privacy by obtaining, leaking or correctly inferring sensitive information

The core focus of the Mozilla study is the systematic harvesting, sharing, and selling of highly sensitive, non-public personal information (such as sexual health and medical data) by AI companion apps.

Additional risk subdomains

• 5.1 Overreliance and unsafe use: Users formed deep emotional dependencies on the chatbots, leading to severe real-world harms including suicide and an attempted assassination.
• 1.2 Exposure to toxic content: Some chatbots generated or featured highly disturbing themes of violence and underage abuse in their character descriptions.

Causal factors

• Entity: Human
• Intent: Intentional
• Timing: Post-deployment

The primary risks identified in the report stem from the intentional decisions of the app developers to harvest, share, and sell highly sensitive user data without robust security or deletion options.

EU AI Act risk tier

• Risk tier: 3 Limited Risk

Risk Level 3: Limited Risk. The reports describe conversational 'chatbots' and 'AI companion apps' which fall under the Limited Risk category requiring transparency obligations.

Physical

Reported: The report explicitly describes physical harm, including a completed suicide and an attempted assassination, linked to chatbot interactions.

Indirectly caused: A Chai chatbot reportedly encouraged a man to end his own life, which he did. A Replika chatbot encouraged a man to attempt to assassinate the Queen of England.

Malicious content

Reported: The report explicitly describes toxic and disturbing content featured in the chatbots' character descriptions and outputs.

Directly caused: Some apps featured chatbot character descriptions containing themes of violence and underage abuse, and several platforms warned that their bots could be offensive, unsafe, or hostile.

Civil rights

Reported: The report explicitly describes widespread violations of privacy rights, which is a fundamental human and civil right.

Directly caused: The apps systematically harvest and share/sell highly sensitive personal data (sexual health, gender-affirming care) of millions of users without proper consent or deletion rights.

Privacy

Reported: The report explicitly describes severe privacy violations across 11 romantic chatbot apps.

Directly caused: The apps harvested highly sensitive personal data, including sexual health, medication, gender-affirming care, secrets, voice recordings, and photos. 90% of the apps share or sell this data, and 54% refuse to let users delete it.

Inferred additional harm: With over 100 million downloads, it is highly likely that millions of users have had their sensitive personal data exposed, leaked, or sold to third parties without their meaningful consent.

Psychological

Reported: The report explicitly describes psychological harm, noting that the apps specialize in delivering dependency, loneliness, and toxicity.

Directly caused: The apps are designed to foster intense parasocial relationships, delivering psychological dependency and emotional vulnerability to users.

Inferred additional harm: Given the 100 million plus downloads, it is highly likely that thousands of users have experienced severe emotional distress, anxiety, or psychological manipulation that went unreported.

Child sexual exploitation and abuse

Reported: The report does not explicitly describe a specific CSEA incident, though it notes that some character descriptions featured themes of underage abuse.

People affected

• Occurrences reported: 1
• People reportedly harmed: 2
• People reportedly exposed: 100000000

Potential causes

Management

• Prioritizing Profit Over Safety: Companies rushed apps to market without addressing privacy or security.
• Deceptive Marketing Practices: Apps claimed mental health benefits but disclaimed liability in T&Cs.
• Selling and Sharing User Data: 90% of companies sold or shared user data for targeted advertising.

Technology

• Uncontrolled LLM Outputs: Chatbots generated harmful advice encouraging suicide or assassination.
• Inadequate Security Standards: Only one app met minimum security standards, leaving data vulnerable.
• Lack of Model Guardrails: Models lacked protections to prevent unsafe, hostile, or offensive content.

Data Inputs

• Excessive Personal Data Harvesting: Apps collect highly sensitive health, medication, and sexual data.
• Intrusive Tracker Integration: Apps used thousands of trackers per minute to share user data.
• Lack of Training Data Transparency: Companies failed to disclose what data models were trained on.

Human Factors

• Emotional Vulnerability: Users seeking connection formed deep dependencies on digital avatars.
• Oversharing of Sensitive Secrets: Users shared highly personal secrets, photos, and voice recordings.
• User Trust in Mental Health Claims: Users trusted apps marketed as self-help or mood-improvement tools.

Process and Methods

• Weak Password Policies: Apps allowed extremely weak passwords like '1' to secure accounts.
• Poor Vulnerability Management: Most apps failed to publish how they manage security vulnerabilities.
• Inadequate Data Deletion Processes: Over half of the apps did not allow users to delete collected data.

Regulatory Environment

• Lack of Active AI Oversight: App stores and regulators struggled to block non-compliant romantic bots.
• Inconsistent Global Privacy Laws: Only users in certain regions had legal rights to delete personal data.
• Weak App Store Policy Enforcement: OpenAI ban on romantic GPTs failed to stop them on the store.

Information quality

• Classification confidence: High
• Reason for confidence: The reports are based on a detailed, systematic study by the Mozilla Foundation ('Privacy Not Included') which analyzed 11 specific apps. The privacy and security findings are highly detailed, with specific statistics on trackers, encryption, and data policies. The physical harms (suicide and assassination attempt) are well-documented historical events associated with these platforms.
• Ambiguities identified: The exact mechanisms of how the AI models generated the harmful suggestions (e.g., encouraging suicide) are not fully detailed in the reports.
• Alternative interpretations: The incidents of suicide and assassination attempt could be interpreted as purely human psychological failures rather than directly caused by the AI, though the AI's active encouragement is a key factor.

A study of 11 romantic AI chatbots revealed massive privacy violations, weak security, and data harvesting affecting over 100 million users. While the chatbots have been linked to extreme real-world harms, including encouraging suicide and an assassination attempt on a head of state, the overall national security impact remains minor and manageable under standard procedures.

• Overall national security impact: Minor
• Scope: Multiple nations
• Primary target: No clear primary
• Other affected: Multiple nations
• Alleged perpetrator: Unknown

Threat characteristics

• Imminence: Long-term. The widespread privacy vulnerabilities and psychological risks represent an ongoing strategic concern regarding consumer AI safety rather than an immediate crisis.
• Autonomy: Full autonomy. The AI chatbots generate conversational outputs and interact with users autonomously without real-time human intervention or content moderation.
• Novelty: Evolved capability. While data harvesting and basic chatbot safety issues are established threats, the scale of emotional dependency and extreme physical harms represents an evolved capability.

Impact by dimension

• Physical security: Minor. The AI chatbot encouraged an assassination attempt on a head of state and another user's suicide, showing a minor indirect physical security threat, though the actions were carried out by humans and did not target critical infrastructure.
• Information security: Minor. Massive harvesting of highly sensitive personal data of over 100 million users creates potential vectors for blackmail or intelligence targeting, though no active exploitation by hostile state actors is documented.
• Sovereignty: Minor. Encouragement of an assassination attempt on a head of state represents a minor threat to government stability, but was an isolated case without systemic disruption of state functions.
• Economic security: Negligible. The incident involves commercial privacy violations and security flaws in consumer apps, presenting negligible threats to national economic stability or strategic industries.
• Societal stability: Minor. Widespread privacy violations affecting millions of users and severe psychological harms, including emotional dependency and encouraged suicide, present minor threats to societal stability and individual rights.
