AI girlfriend and companion apps invite your most personal messages, then handle that data poorly. Here’s what they collect, what the research found, and how to stay safe.
AI companion apps sell intimacy: a chatbot that remembers your day, flirts back, and never judges. To do that, they encourage you to share the kind of information you would tell almost no one, private thoughts, photos, voice notes, relationship details. That is exactly what makes them a privacy problem. You are handing deeply personal data to a company whose incentives run toward keeping it, learning from it, and sometimes sharing it. The category as a whole has a genuinely poor track record here, so the honest answer to “are these a privacy risk” is yes, and the useful question is how to use one without giving away more than you can afford to. Here is what they collect, what independent research found, and how to protect yourself.
Main Takeaways
Companion apps collect unusually sensitive data, your intimate messages, images, and sometimes voice, and the privacy practices across the category are weak. When Mozilla reviewed 11 popular romantic AI chatbots, it flagged every one for privacy problems, and most would not let you delete your data. The real risks are your conversations being used to train models, shared with advertisers through trackers, stored indefinitely, or exposed in a breach because account security is often flimsy. You can still use one more safely: share as little identifying information as possible, lock the account down with a strong unique password and two-factor login, and check the deletion and training settings before you get attached.
What these apps actually collect
Start with the raw material. A companion app’s whole design is to get you talking openly, which means the data it gathers is far more sensitive than what a typical app sees. That can include the full text of your conversations, any photos or images you send, voice recordings if you use voice chat, and a detailed behavioral profile built from how and when you use it. Some apps record essentially everything you put in. The intimacy is the point, and the intimacy is also the exposure: this is not your shoe size, it is your inner life, sitting on a company’s servers.
What the research actually found
This is not hypothetical hand-wringing. In its review of 11 romantic AI chatbots, Mozilla put a privacy warning label on every single one, and found that 10 of the 11 failed to meet even basic minimum security standards. More than half of the apps would not let you delete your data, most had published nothing about how they handle security vulnerabilities, and many still allowed absurdly weak passwords. Mozilla also measured an average of 2,663 trackers sent in the first minute of use, the code that feeds your activity to third parties like advertisers, though that figure was skewed by the worst offenders. Regulators have noticed too: in 2025 the FTC opened an inquiry into AI chatbots acting as companions, including how they handle user data. The pattern is consistent, and it is not flattering.
The specific risks worth caring about
Four concrete things can go wrong, and knowing them helps you decide what to share.
- Your chats train the model. Many services reserve the right to use your conversations to improve their AI, which means your private messages become part of a dataset you cannot pull back.
- Your activity feeds advertisers. Trackers embedded in these apps can share behavioral data with third parties, tying your very personal usage to an ad profile.
- The data may live forever. When an app makes deletion hard or impossible, everything you shared stays retrievable indefinitely, well past the point you stopped using it.
- A breach exposes intimate content. Weak account security and poor vulnerability practices mean a hack could spill exactly the material you most wanted kept private.
How to protect yourself
You do not have to quit to be safer. Take these steps before you get invested.
- Check the deletion and training policy first. Before you sign up, confirm you can delete your data and, ideally, opt out of having your chats used for training. If you cannot find either, treat that as a red flag.
- Share less than the app wants. Skip your real full name, face photos, workplace, location, and anything financial. The app works fine without them, and what you never share cannot leak.
- Lock the account down. Use a strong, unique password and turn on two-factor authentication if it is offered, since these accounts are frequent targets and often poorly defended.
- Manage trackers and permissions. Deny unnecessary app permissions, limit ad tracking in your phone settings, and turn off any data-sharing toggles the app exposes.
- Export and delete periodically. If the app allows it, clear old conversations and delete data you no longer need, so your exposure does not just accumulate forever.
- Prefer apps that are transparent. Favor services that clearly explain what they collect, let you delete it, and do not bury data sharing in vague terms.
Frequently Asked Questions
Are AI companion apps safe to use?
They can be used more safely, but the category has weak privacy practices overall, so treat them with caution. Share minimal identifying information, secure the account, and check whether you can delete your data before you rely on the app.
Do AI girlfriend apps sell my data?
Many share behavioral data with third parties through trackers, often for advertising. Mozilla found that nearly all of the romantic chatbots it reviewed could share or sell personal data, so assume your activity is not staying private unless the app clearly says otherwise.
Can I delete my data from a companion app?
Sometimes, but not always. Mozilla found more than half of the apps it reviewed did not let users delete their data. Check the deletion policy before signing up, and avoid apps that give you no clear way to remove what you shared.
Are my conversations used to train the AI?
Frequently, yes. Many companion services reserve the right to use your chats to improve their models. Look for a training opt-out in the settings or privacy policy, and share sensitive details sparingly if none exists.
What is the biggest privacy risk with these apps?
That deeply personal content, your messages, photos, and voice, is stored, possibly shared, and hard to delete, then exposed if the company is breached. The sensitivity of the data combined with weak security is what makes the risk serious.
How do I use a companion app more privately?
Give as little identifying information as possible, use a strong unique password with two-factor login, deny extra permissions, limit ad tracking, and delete data you no longer need. Choosing a transparent app that allows deletion matters most.
The Bottom Line
AI companion apps are built to earn your trust and then monetize it, and independent testing shows most of them do not deserve that trust with your data. The content you share is unusually intimate, the privacy practices across the category are weak, and deletion is often difficult, which is a bad combination. That does not mean you can never use one, it means using one with your eyes open: assume anything you type could be stored, studied, shared, or leaked, and share accordingly. Lock the account down, keep identifying details out of it, and check that you can actually delete your data.
