What data do AI companion apps typically collect?
At minimum, an AI companion app collects the messages you send and receive, since that conversation history is what the underlying model and any memory system operate on. Depending on the app, additional data may include account details (email, payment info for paid tiers), device and usage analytics, and — on apps with voice or image features — voice recordings or uploaded images. What happens to that data next (how long it's kept, whether it's used to train models, whether it's shared with third parties) is determined entirely by that specific app's privacy policy, not by any industry-wide rule.
How does age verification actually work on these apps?
This varies more than most users expect. In our testing across the category, we've seen a few common approaches:
- Self-declared birthdate or checkbox: the lightest form — a user enters a birthdate or checks an "I am 18+" box with no further check. This is common but easy to bypass, so it offers limited real protection.
- App-store age rating gate: the app relies on the age rating and account settings of the app store it's distributed through (Apple App Store / Google Play), which has its own separate verification mechanisms.
- Third-party ID or payment-based verification: a smaller number of platforms, usually ones offering explicit adult content, use an ID check or require a verified payment method tied to an adult-only account tier.
Because this is inconsistent, we treat "has age verification" as something to check per app rather than something you can assume is standardized across the category.
What are content filters, and are they the same thing as age verification?
No — these are two different controls and it's easy to conflate them. A content filter (often labeled as an "SFW/NSFW toggle" or "content preference" setting) governs what kind of content the app will generate for an account that is already signed in. Age verification is the separate, earlier step that's supposed to determine who is allowed to create that account or unlock that toggle in the first place. An app can have a strict content filter with weak age verification behind it, or the reverse — so check both independently rather than assuming one implies the other. See our glossary entry on content filters for more detail.
A practical checklist before you sign up
- Open the app's privacy policy and search for "third party," "share," and "retention" to see what it actually says about your data.
- Check what age-verification method is used — a checkbox, an app-store gate, or ID/payment verification — and decide if that's sufficient for your situation.
- Look in account settings for a content filter or "mature content" toggle, and confirm it defaults to the setting you expect.
- Check whether the app offers an in-app way to view, export or delete your stored conversation and memory data.
- If you're evaluating the app for a minor or with parental-control needs in mind, verify directly with the app whether it supports that use case — don't assume based on general app-store category norms.
How CompanionRank handles this in reviews
When we review an app, we read and summarize what its own privacy policy states, and we note the age-verification step we encountered during our own account creation. We do not audit an app's backend systems or independently confirm data-retention practices beyond what's publicly documented — see our full review methodology for exactly where our verification stops and vendor-reported information begins.

Do AI companion apps sell my chat data?
It depends on the app, and the only reliable way to know is to read that app's own privacy policy, specifically the sections on data sharing with third parties and use of conversation data for model training or advertising. Policies differ significantly between apps.
How do these apps verify age?
Methods vary widely — some rely on a simple birthdate entry or checkbox at signup, others use app-store age ratings, and a smaller number use third-party ID or credit-card based verification for access to adult content.
Can I delete my data after I stop using an app?
Most privacy policies describe an account-deletion process, but retention periods for backups and de-identified data can still vary. Look for a specific data-deletion section in the app's privacy policy, and use the in-app deletion option rather than simply uninstalling the app.
Are content filters the same as age verification?
No. A content filter controls what kind of content is generated within an account that's already logged in. Age verification is a separate, earlier step meant to control who can create that account in the first place.
