Quick Answer
- Documented tracker warning: CrushOn AI received a WARNING label from Mozilla's Privacy Not Included project , 45 trackers including DoubleClick loading within the first minute
- Documented data breach: Muah AI suffered a September 2024 breach exposing roughly 1.9 million email addresses and intimate chat prompts
- Policy contradicts marketing: FantasyGF claims to encrypt conversations, but that claim is not reflected in its own written privacy policy, and data is shared with third parties per the policy itself
- Verified strong privacy: Clonella uses end-to-end encryption and explicitly states it does not train on user chats, with crypto payment accepted
- No cloud platform is provably private: even strong-privacy platforms store data on servers you do not control
What "Selling Your Data" Actually Means Here
Very few platforms literally sell your chat transcripts to a named buyer. The more common and more relevant risks are: third-party trackers embedded in the app that feed your behavior to ad networks, data breaches exposing what you thought was private, and privacy policies that permit sharing with unspecified "partners" in language most users never read. All three are effectively the same practical risk , your intimate conversations becoming visible or valuable to someone other than you and the platform.
Platform-by-Platform, What's Actually Documented
CrushOn AI , Mozilla's Privacy Not Included project assigned a WARNING label, its worst rating, after finding 45 trackers loading within the first minute of use, including DoubleClick. This is a specific, independently verified finding, not general suspicion. See our CrushOn AI review 2026 for the full breakdown, including why the platform still has real strengths despite this.
Muah AI , suffered a confirmed data breach in September 2024 exposing approximately 1.9 million email addresses alongside intimate chat prompts, the most significant documented privacy incident in this category. The company disclosed it and has since tightened encryption and account deletion. See the Muah AI companion page for the full context.
FantasyGF , an independent review specifically found the platform's marketing claims encryption while its own written privacy policy does not reflect that claim, and user data is shared with third parties per the policy document itself. That gap between marketing language and actual terms is worth reading carefully on any platform, not just this one. See our FantasyGF AI review 2026.
GirlfriendGPT , public information on encryption and data storage practices is limited, and user data retention is comparatively long, though no breach is on record for the domain. See the GirlfriendGPT review 2026.
Clonella , the clearest positive example on this list. End-to-end encryption on all conversations, an explicit statement that chat data is not used to train AI models, and cryptocurrency payment accepted for users who want maximum payment privacy on top of message-level encryption. See the Clonella AI review 2026.
SoulGen , collects limited user data with automatic deletion after 7 days, complying with GDPR and Hong Kong's Personal Data Privacy Ordinance , a shorter retention window than most competitors disclose. See the SoulGen AI review 2026.
How to Check Any Platform Yourself
Read the privacy policy, not the marketing page. FantasyGF's case shows exactly why this matters , the homepage said one thing, the policy said another.
Search for the platform name plus "Mozilla Privacy Not Included." Mozilla's project independently rates a wide range of connected products including several AI companion apps, and its findings are specific and citable rather than speculative.
Search for the platform name plus "data breach." A past breach is disclosed information, not automatically disqualifying , what matters is whether it happened, whether it was disclosed honestly, and what changed afterward.
Look for an explicit no-training-on-chats statement. Most platforms are silent on this. Clonella states it directly, which is unusual enough to be a genuine differentiator.
Consider a burner email and VPN as a default, not a special precaution, on any adult platform regardless of its stated policy , this is standard practice recommended even for platforms with no documented issues.
Top Picks by Privacy Priority
If verified end-to-end encryption matters most: Clonella , the strongest documented privacy posture on our roster, plus crypto payment option.
If you want a platform with no documented breach or tracker warning: Darlink AI or Selira AI, both with no public privacy incidents on record.
If you want short data retention specifically: SoulGen AI, 7-day auto-deletion.

FAQs
Do AI girlfriend apps sell your data?
It varies by platform and is checkable rather than assumed. CrushOn AI received a Mozilla WARNING label for 45 trackers including DoubleClick. Muah AI had a confirmed 2024 breach. FantasyGF's marketing claims encryption its own policy does not support. Clonella, by contrast, uses end-to-end encryption and explicitly states it does not train on chats. Read the actual privacy policy of any platform you use, not just the marketing page.
Which AI girlfriend app has the strongest verified privacy?
Clonella , end-to-end encryption on all conversations, an explicit no-training-on-chats statement, and cryptocurrency payment accepted. This is the strongest documented privacy posture among platforms we have reviewed.
Has an AI girlfriend app ever had a real data breach?
Yes. Muah AI suffered a confirmed breach in September 2024 exposing approximately 1.9 million email addresses and intimate chat prompts. The company disclosed the breach and has since made changes to encryption and account deletion. See our Muah AI companion page for details.
What does a Mozilla Privacy Not Included WARNING label mean?
It is the worst rating Mozilla's independent consumer privacy project assigns. For CrushOn AI, it followed documentation of 45 trackers, including DoubleClick, loading within the first minute of using the platform , a specific, verifiable finding rather than general privacy concern.
Is it safe to share intimate details with any AI companion app?
No cloud-based platform can offer provable privacy for explicit content , even strong-privacy platforms store data on servers you do not directly control. The practical approach is choosing platforms with documented, verified privacy commitments like Clonella, avoiding platforms with known tracker warnings or breaches, and using a burner email as standard practice.
