AI companion apps and your privacy: what they collect and what they keep
Of all the things you might do online, an intimate conversation with an AI companion is among the most personal — which is exactly why the privacy question deserves more weight here than in an ordinary app review. You are, by design, telling these products things you might not tell anyone. What happens to that data is not a footnote; for many readers it should be the deciding factor.
Here’s how to think about it, and what we look for when we score privacy.
What these apps collect
Beyond the obvious account details, a companion app typically logs the full content of your conversations — that’s how the “memory” works. Many also collect uploaded images, voice recordings, device and usage data, and inferred preferences built up over time. The richness that makes a companion feel personal is, from a data perspective, a detailed and sensitive profile.
The four questions that actually matter
Most privacy policies are written to be technically accurate and practically unreadable. Cut through them with four questions:
What is retained, and for how long? Some providers keep conversation history indefinitely; others offer auto-deletion or let you wipe it. Indefinite retention of intimate data is the weakest position.
Is your data used to train models? Many apps reserve the right to use your conversations to improve their systems. That’s not automatically sinister, but it means your words may persist inside a model, and you should know if you can opt out.
Who else can see it — and is it sold or shared? Look for sharing with “third parties” for advertising, analytics or unspecified “business purposes.” Broad sharing language is a red flag for data this sensitive.
How is it secured, and can you delete it? Encryption, a clear deletion path, and an honest breach history matter. A provider that makes deletion easy and retention short is signalling that it takes this seriously.
Practical steps regardless of app
A few habits reduce your exposure no matter which product you choose:
Use a dedicated email rather than your main one. Be deliberate about uploading identifying photos. Turn off training/data-sharing options where they exist. Periodically clear conversation history if the app allows it. And assume that anything you send could, in a worst case, be exposed — and calibrate what you share accordingly.
How we score it
Privacy is one of our four headline metrics, scored on the four questions above: retention, training use, sharing, and security plus deletion. An app can have excellent conversation quality and still score poorly here — and when it does, we say so prominently, because for a product built on intimacy, weak privacy isn’t a minor flaw. It’s the flaw.
Common questions
Are AI girlfriend apps safe to use privately?
It varies enormously by app. The conversations are sensitive by nature, so what matters is the provider's data practices: what they store, how long they keep it, whether it's used to train models, and how well it's secured. Few apps are transparent about all four, which is why we score privacy separately.
Do AI companion apps sell your data?
Some have privacy policies broad enough to permit sharing with third parties for advertising or analytics. Others commit not to. The only reliable way to know is to read the policy — we summarise the key points in each review.
Can my AI companion conversations be leaked?
Any data a company stores can in principle be breached, and companion apps hold unusually sensitive data. Providers with strong security, short retention and clear deletion options reduce — but never eliminate — that risk.
