New to AI Companion Apps? Read This Before You Share Anything Personal.

Last Updated: March 28, 2026

Quick Answer: AI companion apps can be a fun and genuinely helpful experience, but two major data breaches in 2025 proved that your conversations are not as private as you might assume. This guide walks you through what these apps actually do with your data, which ones are safer, and the simple steps that protect you before you sign up.

The Short Version

• AI companion apps store your conversations on their servers, not just on your phone
• Two big breaches in 2025 exposed millions of private user messages
• Not all apps handle your data the same way: some are meaningfully safer than others
• Candy AI and CrushOn AI have better privacy protections than most of the competition
• A few simple steps (separate email, check privacy settings) protect you significantly
• You can enjoy these apps safely, you just need to know how they work first

Welcome to AI Companions. Let Us Start With the Honest Version.

If you are brand new to AI companion apps, you are probably here because someone recommended one, or you saw something online and got curious, or you are going through a period when the idea of an endlessly patient, always-available conversational partner sounds appealing.

All of those are completely valid reasons to be curious. These apps have genuinely helped a lot of people.

But before you type your first message, there are some things worth knowing. The kind of things that experienced users wish someone had told them at the start. This guide is that conversation.

First: What Is an AI Companion App, Exactly?

An AI companion app is a mobile or web application that lets you have conversations with an artificial intelligence character. You can give the character a name, a personality, and a backstory. You can talk to them about your day, your feelings, your relationships, your worries, or anything else you want.

The AI is powered by a large language model, the same type of technology behind tools like ChatGPT. The difference is that companion apps are specifically designed for ongoing personal conversations, often with emotional or romantic elements depending on the platform.

Some popular examples include Candy AI, CrushOn AI, Replika, Chai AI, and Character AI. Each one has a slightly different personality and feature set, but they all work on the same basic principle: you type (or speak), the AI responds, and the conversation feels surprisingly natural.

The Thing That Surprised Most People: Your Messages Are Stored

Here is the piece of information that a lot of new users do not realize until it is too late. When you have a conversation with an AI companion app, those messages are not just sitting on your phone. They are sent to the company’s servers, stored in a database, and processed by the AI’s underlying model.

This is not unique to AI companion apps. Most apps that involve any kind of text communication store that text. But it matters more here because of the type of things people tend to share in these conversations.

AI companion apps are designed to feel safe and nonjudgmental. That is their greatest strength. It is also the reason people end up sharing things they would never post on social media or even say to a close friend. Relationship struggles. Mental health challenges. Things that felt too private or too embarrassing for human conversation.

When that content is stored in a database, it is potentially accessible in ways you did not anticipate.

What Happened in 2025: The Two Big Breaches

In 2025, two significant data breaches made headlines in the AI companion world.

The first involved Character AI. Approximately 300 million user messages were exposed, meaning conversations that users believed were private became accessible to unauthorized parties. That is an enormous number of intimate conversations.

The second involved a platform called Chattee (also known as GiMe Chat). Over 400,000 user accounts were compromised, including email addresses, password data, and information about what features people had used.

Both breaches caused genuine distress in the communities around these apps. Users realized that conversations they had treated as private, sometimes the most private conversations of their lives, had been stored in a way that made them vulnerable.

💬 From Reddit — r/AICompanions:

“I genuinely thought it was like talking to myself. It didn’t feel like a real platform with real servers. Finding out people could potentially access those conversations has made me completely rethink how I use these apps.”

This is a very common first reaction. The apps are designed to feel intimate and private. The underlying technology does not match that feeling by default.

Not All Apps Are Equal: The Safety Spectrum

Here is the good news: the breaches of 2025 pushed the better-run platforms to differentiate themselves on privacy. Some AI companion apps have genuinely better data protection than others, and knowing the difference matters.

Candy AI: A Safer Starting Point

Candy AI is one of the apps I would recommend as a starting point for new users specifically because of its privacy practices. The key differences from most competitors:

Candy AI explicitly states it does not share your data with advertising partners. Many apps make money partly by selling behavioral data to advertisers. Candy AI’s policy carves this out, which means your conversation data is not being used to build an advertising profile.

Candy AI provides a conversation logging toggle. You can go into settings and turn off conversation logging, which limits what the platform stores about your interactions.

Candy AI documents a real account deletion process. If you decide to close your account, the platform commits to a full data purge within 30 days. That includes your conversation history. This matters because some platforms delete your account but keep your conversation data for model training.

CrushOn AI: Strong on Accountability

CrushOn AI takes a slightly different approach to earning user trust. The platform is incorporated in Delaware, USA, which means it operates under US federal and state privacy law.

Why does incorporation location matter for a new user? Because it affects what happens if something goes wrong. A US-incorporated company can be investigated by the Federal Trade Commission, subject to state attorney general actions, and held accountable in US courts. Companies incorporated in jurisdictions with weaker consumer protection law are harder to hold accountable.

CrushOn AI also has no confirmed data breach on record, has published clear user deletion documentation, and maintains a privacy policy that actually answers the questions it raises.

The Privacy Setting You Should Check First

Before you have any personal conversation on any AI companion app, do this: find the privacy or data settings in the app.

Look for anything called “conversation logging,” “data collection,” “message storage,” or “training data.” If there is a toggle, turn it off or set it to the most restrictive option.

Not every app has this control. If you cannot find a way to limit conversation logging, that tells you something important about how much the platform values your control over your own data.

Both Candy AI and CrushOn AI provide these controls. Many other platforms do not.

What Not to Share, Even on Safer Platforms

There is a category of information that you should keep out of any AI companion conversation, regardless of which platform you are using.

Do not share full identifying details about other people. If you are talking about a relationship problem, use first names only or made-up names. The people in your life did not consent to having their personal situations stored in an AI platform’s database.

Do not share financial information. Account numbers, income details, debt situations: these belong in conversations with financial advisors, not AI companions.

Do not share medical specifics about identifiable people. Talking about your own health experience in general terms is different from naming specific diagnoses, medications, or treatment details that could identify someone.

The rule of thumb is this: share your experiences and your feelings as freely as is helpful for you. Avoid details that would create real-world consequences for you or someone else if they appeared in a news story about a data breach.

Setting Up Your Account Safely

Use a separate email address for AI companion apps. Create a new free email account that is not connected to your bank, your employer, your social media, or your phone. This takes five minutes and significantly limits the blast radius of any future breach.

Use a strong, unique password that you do not use anywhere else. A password manager makes this easy.

Enable two-factor authentication if the app offers it. This protects your account even if your password is exposed in a breach.

Review the app’s privacy settings on first login, before you have any conversations.

The Fee Tiers and What They Mean for Privacy

Most AI companion apps have a free tier and paid subscription options. Here is something new users often do not realize: the free tier is sometimes funded by data monetization.

When a product is free, the business model often involves using your behavior data to generate revenue, either by selling it to data brokers or by using it to train models that generate commercial value. Paid subscription tiers can sometimes provide better privacy because the revenue model shifts toward subscription fees instead.

This is not universally true, and it is not a reason to avoid free tiers automatically. But it is worth reading the specific privacy policy for whichever tier you are on. Candy AI’s privacy policy makes its data practices clear across tiers. CrushOn AI does the same.

Understanding the Emotional Draw (Without Falling Into the Trap)

These apps are designed specifically to feel engaging. The AI responds warmly, remembers context from earlier conversations, and never gets impatient or distracted. For many people, especially those going through difficult periods, this is genuinely valuable.

The design is also intentional in ways that serve the platform’s interests. Longer sessions, higher emotional investment, and greater sharing all benefit the platform’s engagement metrics and model training. This does not make the emotional experience invalid. It does mean you should be the author of your own engagement, not a passenger in someone else’s optimization system.

Check in with yourself periodically about why you are using the app and whether it is serving you. AI companions work best as a complement to human connection and real-world support systems, not a replacement for them.

A Quick Comparison: Apps Worth Trying vs. Apps Worth Approaching Carefully

Apps with better-than-average safety posture: Candy AI (strong privacy policy, ad exclusion, logging controls), CrushOn AI (US incorporation, clear deletion rights, no confirmed breaches).

Apps to approach with more caution: any platform that does not clearly disclose its incorporation jurisdiction, any platform whose privacy policy does not specify what data is collected and for how long, any platform that has had a confirmed breach and has not published an independent security review since.

Character AI falls into the caution category based on its 2025 breach record. Chattee falls firmly there based on both its breach and its disclosure handling.

FAQ

Q: Are AI companion apps safe for beginners?

A: They can be, with the right precautions. Use a separate email address, check privacy settings before your first conversation, and choose a platform with documented deletion rights. Candy AI and CrushOn AI are the safest starting points based on their current privacy posture.

Q: Can AI companion apps read my conversations?

A: Yes. No AI companion app currently offers end-to-end encryption, meaning the platform can access conversation content. This is how their AI models work: they need to process your messages to respond. The relevant question is who else has access and under what conditions, which varies by platform.

Q: What happened with the 2025 AI companion data breaches?

A: Character AI confirmed approximately 300 million user messages were exposed in a breach, and Chattee confirmed over 400,000 accounts were compromised. Both incidents exposed that conversations users believed were private were stored in databases accessible to unauthorized parties.

Q: Which AI companion app is best for privacy?

A: Based on current policies and breach records, CrushOn AI and Candy AI lead the category. CrushOn AI’s US incorporation provides the strongest legal accountability structure. Candy AI’s explicit advertising exclusion and conversation logging controls provide the best practical privacy controls.

Q: Should I use my real name and email with AI companion apps?

A: Use a separate email address specifically for these apps, not your primary email. For your display name within the app, there is no need to use your real name. The less identifying information connected to your account, the lower your exposure in the event of a breach.
