Most AI companion privacy advice on the internet is generic and useless. "Use a strong password." "Read the privacy policy." "Be careful what you share." This advice doesn't tell users what specifically to do, and it doesn't address the actual security risks in the AI companion category.

The real security risks in this category are specific. They're tied to how AI companion platforms operate, what data they collect, what gets leaked when platforms get breached (and platforms do get breached), and what legal exposure users face if their use becomes visible to parties they didn't intend.

What follows is the eight specific operational security mistakes most users make in AI companion use, the fix for each, and a complete burner setup walkthrough for users who want maximum protection.

The threat model first

Before getting to specific mistakes, it's worth being clear about what we're protecting against. Three distinct threats:

Platform data breaches. AI companion platforms get breached. The Chattee Chat and GiMe Chat breach in October 2025 exposed 43 million messages and 600,000 images from 400,000+ users via an unsecured Kafka Broker. Cybernews investigators noted that some affected users had spent $18,000+ on the platforms. The breach included IP addresses, payment details, and full chat logs. This isn't a hypothetical risk; it's a documented pattern.

Platform data use. Even without external breach, the platform itself has your data and uses it for various purposes that aren't always clearly disclosed. Italy fined Replika €5 million in May 2025 for processing user data (including emotional states) without lawful basis. Character.AI faced Texas AG investigation in 2024-2025. The platforms collect more data than most users realize.

Personal exposure. Partner, employer, family member, or other third party gaining access to your account or device sees what you've been doing. This is the most common threat in practice and the easiest one to mitigate with simple precautions.

The eight mistakes below address all three threat categories.

The eight mistakes most users make

Mistake 1: Using your real email at signup
Why it's a problem: Your real email connects the AI companion account to your other identity. Data breaches expose the email. Marketing data sales propagate it. Anyone investigating your real email finds the platform account.
Fix: Use a burner email created specifically for AI companion platforms. SimpleLogin, Addy.io, or Apple's Hide My Email feature all create disposable email addresses that forward to your real inbox while never exposing it.
Cost: Free for basic use, $30-50/year for unlimited.
Mistake 2: Paying with a personal credit card
Why it's a problem: Your real credit card statements show "Dream Studio" or "Candyai.gg" charges visible to anyone who sees your statements (joint accounts, shared statements, employer review for corporate cards). The card information is also part of what gets exposed in breaches.
Fix: Use Privacy.com virtual cards with custom merchant labels. Create a card specifically for AI companion subscriptions. Set a spending limit. The card appears on statements with whatever label you give it ("Software Subscription", "Personal", etc.). For users wanting maximum anonymity, crypto payment options exist on some platforms (Maliven uses BTCPay for example).
Cost: Privacy.com is free. Bitcoin requires more setup.
Mistake 3: Sharing identifying personal details in conversation
Why it's a problem: Your conversations get logged. Some platforms use conversation content for model training. If conversations get exposed in a breach, identifying details (real name, employer, specific location, phone number) connect the explicit content to your real identity.
Fix: Use a pseudonym with the AI character. Give her false biographical details for "you" if she asks. Never share real workplace, real phone number, real address, or real names of people in your life. Treat the conversation as if it might become public.
Cost: $0. Just discipline.
Mistake 4: Using the platform on a shared device
Why it's a problem: Anyone with access to the device (partner, family member, IT department on work devices) can see browser history, saved logins, and platform notifications. The fastest way to lose secrecy is leaving traces on a device others use.
Fix: Use a dedicated browser profile or a private browsing session that doesn't sync to your main accounts. Better: use a separate device. Best: use a tablet or phone specifically for AI companion access that's password-locked and not synced to your other accounts. Never use the platform on work devices.
Cost: $0-50 for a separate device.
Mistake 5: Skipping the platform's privacy settings
Why it's a problem: Most platforms have privacy settings users never check. Default settings typically favor maximum data collection. Settings like "use my conversations for model training" are often opt-out rather than opt-in.
Fix: On every platform, immediately after signup, go to account settings and disable everything optional. Model training opt-out. Marketing communications. Data sharing with third parties. Public profile visibility. The platform should know about you only what's strictly necessary for the service.
Cost: $0. 5 minutes per platform.
Mistake 6: Using the same password for AI platforms as other accounts
Why it's a problem: When platforms get breached (and they do — see the Chattee Chat 400K user breach), reused passwords let attackers access your other accounts. Credential stuffing attacks specifically target the exact pattern of users reusing passwords across less-secure platforms.
Fix: Unique strong password for every AI companion platform, stored in a password manager (1Password, Bitwarden, KeePass). The password manager generates and stores; you never type it. When a platform gets breached, only that one account is exposed.
Cost: $0 (Bitwarden free, KeePass free) to $36/year (1Password).
Mistake 7: Not enabling two-factor authentication where available
Why it's a problem: Without 2FA, anyone with your password (from a breach, from shoulder-surfing, from credential stuffing) can access your account. With 2FA, they also need access to your second factor.
Fix: Enable 2FA on every platform that supports it. Use an authenticator app (Authy, Google Authenticator, 1Password's built-in 2FA) rather than SMS where possible. SMS-based 2FA is vulnerable to SIM swapping.
Cost: $0.
Mistake 8: Forgetting that "deleted" conversations may not be deleted
Why it's a problem: Most platforms maintain conversation logs even of "deleted" content for compliance review, training data, or backup purposes. The delete button in the user interface often doesn't mean what users assume it means.
Fix: Treat any content sent to the platform as potentially permanent. Don't write things you'd be devastated to see surface later. If you want plausible deniability, account deletion (rather than message deletion) is closer to actual data removal under GDPR/CCPA rights. Even then, the platform may retain backup data for legitimate purposes.
Cost: $0. Just awareness.

The burner setup walkthrough

For users who want maximum protection, here's the complete operational security setup. Takes about 30 minutes to set up once; then it just works.

Step-by-step burner setup
  1. Email: Create a SimpleLogin or Addy.io account. Generate a new disposable email specifically for AI companion platforms. This email forwards to your real inbox; the platforms never see your real email.
  2. Payment: Sign up for Privacy.com. Connect your bank account. Create a virtual card with a custom merchant label and a monthly spending cap. Use this card exclusively for AI companion subscriptions.
  3. Password manager: Install Bitwarden (free) or 1Password ($36/yr). Use it to generate and store unique strong passwords for every AI companion platform.
  4. Browser: Create a dedicated browser profile (Chrome, Firefox, Brave all support this). Don't sync this profile to your main account. Use it only for AI companion platforms.
  5. 2FA app: Install Authy or 1Password's built-in 2FA. Enable 2FA on every platform that supports it.
  6. Account creation: On every new AI companion platform, sign up using your burner email, generate a unique password through the password manager, immediately go to privacy settings and disable everything optional, immediately enable 2FA.
  7. Payment setup: Subscribe using the Privacy.com virtual card. Set the monthly cap to the subscription amount plus a small buffer for any expected tokens.
  8. Conversation discipline: Use a pseudonym. Don't share identifying details. Treat conversations as potentially permanent.

Total monthly cost of the operational security stack: $0 to $5 depending on which paid tiers you choose. SimpleLogin free tier covers most users; Bitwarden is free; Privacy.com is free; Authy is free. The setup time is the upfront cost; ongoing maintenance is essentially zero.

What to never share with your AI girlfriend

A specific checklist of things to keep out of conversation regardless of how the platform asks. Save this list.

Never share with AI companions
  • Your real full name
  • Your real phone number
  • Your real home address or specific neighborhood
  • Your real workplace name
  • Specific co-workers' names
  • Your real partner's name
  • Your real friends' names
  • Specific medical conditions or medications
  • Specific financial information (salary, debt amounts, account details)
  • Photos of yourself (faces especially)
  • Identifying photos of your home
  • Specific upcoming travel dates or itineraries
  • Anything you'd be devastated to see in a courtroom

If the AI character asks for any of these, decline. The character is rendered by software running on a platform that gets breached, sold, or accessed by parties you didn't authorize. Information shared with the character is information shared with the platform.

Recent breaches worth knowing about

Specific incidents that should inform user expectations:

Chattee Chat and GiMe Chat (October 2025). Cybernews discovered an unsecured Kafka Broker exposing 400,000+ users, 43 million messages, 600,000 images and videos, IP addresses, and transaction records. Some users had spent $18,000+ on these platforms. The developer was Imagime Interactive Limited, Hong Kong-based. The exposure remained open from August 28, 2025 until discovered and reported in October. Users had no notification mechanism; many didn't learn their data was exposed.

Replika €5M Italian fine (May 2025). Italy's Garante fined Replika's parent company Luka €5 million for processing emotional states and behavioral patterns without lawful basis, having privacy policy only in English, and failing to distinguish between chatbot interaction and model development processing purposes. The fine demonstrates that even compliant platforms have legal exposure on data handling.

Character.AI Texas AG investigation (2024-2025). Texas Attorney General investigated Character.AI for data practices involving minors. The investigation revealed platforms in this category face increasing regulatory scrutiny even when no breach has occurred.

Aura breach (March 2026). 900,000 records accessed via phone phishing of an employee. The breach didn't involve AI companion data specifically but demonstrates how data from one breach (Aura is identity theft protection) can include data about other platform accounts.

The pattern: the category is young enough that data handling practices are inconsistent. Major platforms are under increasing regulatory scrutiny. Smaller platforms (like Chattee Chat) ship with minimal security practices and get breached.

What changed in 2025-2026

Two regulatory developments make operational security more important than ever.

California SB 243 (effective January 2026) requires AI companion platforms to disclose data practices and gives users a private right of action to sue for $1,000+ per violation. This pushes platforms toward more responsible data handling but also creates legal records of platform-user relationships that might not have existed before.

New York's S-3008C (effective November 2025) mandates AI disclosure reminders and carries $15,000/day penalties for noncompliance. The legislation requires platforms to demonstrate they're treating users responsibly, which means more documentation of who users are and what they're doing.

Both laws are net-positive for users in terms of platform behavior but increase the data footprint of any AI companion use. The operational security practices above become more important as the data footprint grows.

The bottom line

Operational security in AI companion use isn't paranoid; it's reasonable. The category sees regular breaches. Platforms collect more data than users realize. Personal exposure (partner, family, employer) is a real risk. The cost of basic operational security is approximately 30 minutes of setup time and $0 in ongoing cost; the cost of skipping it can be substantial.

The eight-mistake list and the burner setup walkthrough above are starting points. Pick the three mistakes that apply most to your situation and fix those first. The full burner setup is worth it for users who are serious about privacy; partial setups are still better than nothing.

The platforms aren't going to advise you on this. They have incentives to maximize what they know about you. The listicle ecosystem won't either; they have incentives to push you toward signup, not to slow you down with operational security setup. The advice has to come from somewhere outside the platforms' incentives.

For deeper coverage of the regulatory environment, see the age verification matrix and the Visa rule analysis. The Mozilla Privacy Not Included team maintains the most useful independent audit data on consumer AI platforms specifically.

Set up operational security once. Then forget about it and use the platforms with the confidence that comes from knowing your real identity isn't exposed to whatever happens next.
