Is Muah.ai Safe? (2026 Review)

The short answer

Muah.ai had a serious, public, well-documented data breach on October 8, 2024. Roughly 1.9 million email addresses plus associated chat prompts were exfiltrated, and the prompt data included explicit requests for CSAM, which attracted law enforcement attention and press coverage. The founder’s own quote describing the infrastructure as “basically duct-taped” made the rounds. If you care about data security even a little, this is the one app on the popular list where the concern isn’t theoretical: it’s already happened. That’s why the verdict here is caveated, not “mostly safe.” Use only with a throwaway email, never your real one.

What data does Muah.ai collect?

Signup requires an email. Phone numbers are not required. Muah stores chat logs, prompt text, image generation prompts, generated images, character setups, and payment metadata via its processor. Crucially, in the 2024 breach, what leaked was the email-to-prompt mapping, meaning attackers could see which email address had requested which content. That’s the exact data shape that makes breaches catastrophic for this category of app.

Email verification has historically been light, so alias emails work. There’s no ID verification.

Who owns the company?

Muah.ai’s corporate structure is less transparent than competitors like Candy or DreamGF. The operating entity has used multiple names and the jurisdiction has shifted in public records. The founder gave interviews to 404 Media and Wired around the time of the breach, which is the main public-facing information available. I don’t have a current, verified filing to point you at, so I won’t pretend otherwise.

Compared to EverAI (Candy) or the operator behind DreamGF, Muah.ai is noticeably less institutional. That alone isn’t damning, but combined with the breach it’s a pattern.

Has Muah.ai had a breach or incident?

Yes. On October 8, 2024, a hacker exfiltrated Muah.ai’s database and shared it with 404 Media. The dump contained approximately 1.9 million email addresses along with chat prompts, character setups, and associated metadata. Because Muah.ai is an uncensored AI companion, the prompt data included explicit content, and a non-trivial subset involved requests for child sexual abuse material. That detail drove significant press coverage and is understood to have prompted law enforcement interest.

The founder, in coverage by Wired and 404 Media, described the company’s infrastructure as effectively “duct-taped together,” acknowledging the security was inadequate. The breach exposed users to extortion risk: attackers could (and in some cases did) contact people using their real email addresses referencing their specific prompts.

Since the 2024 incident, Muah.ai has made public statements about improving security. Whether the improvements are substantive is not independently verified.

Payment safety

Muah.ai uses third-party payment processors (historically CCBill and others common in adult billing). Your card number does not touch Muah.ai’s own servers. The processor handles the card data. That part of the stack is the same industry-standard setup other apps use, and wasn’t the failure point in 2024.

The merchant descriptor varies and is usually some variant of the processor’s generic descriptor, which tends to be relatively discreet on statements. Still, pay with a virtual card. Given the breach history, you want every layer of separation you can get between Muah.ai and your real financial identity.

Content on your device vs on their servers

Everything is server-side, and the 2024 breach proved it: the leaked data included chat content, not just account metadata. Deletion requests can be submitted; how thoroughly content is purged from backups is not independently verified. If you’re an EU user, GDPR applies and you can demand a full deletion.

Generated images are stored server-side. Again, the 2024 breach demonstrated what that actually means in practice.

Can anyone see what you’ve done?

By default, no: accounts are password-protected and Muah has no public profile system. But the 2024 breach already answered the “what if there’s a leak” question in the worst possible way: for 1.9 million users, their email address is now publicly associated with specific prompts. If you signed up before October 2024 using your real email, that information is already out there.

For new signups post-breach, the risk is lower than it was, but it’s not zero, and Muah has the worst track record in the category.

How to minimize your exposure

• Use a throwaway email alias, not your main address. This is non-negotiable for Muah specifically
• Pay with a virtual card (Revolut, Privacy.com), not a card tied to your main bank account
• Never upload photos of yourself or anyone you know
• Assume every prompt could end up public; write accordingly
• Use a strong unique password that you don’t reuse anywhere else
• If you signed up pre-October-2024 with your real email, check HaveIBeenPwned and rotate any reused passwords immediately

Is Muah.ai safer than Candy.ai?

No. Candy.ai has no public breach history, a named EU-based corporate operator, and GDPR coverage. Muah.ai had a 1.9 million-user breach, a self-admitted weak security posture, and a less transparent corporate structure. On the pure safety question, this isn’t close: Candy, DreamGF, and most competitors have a materially better track record. The only reason to pick Muah.ai over a competitor in 2026 is product features, and you pay for those features in risk.

Our verdict

Muah.ai is caveated. This is the one app in the popular companion space where the worst-case scenario has already materialized. The 2024 breach wasn’t hypothetical. It happened, it was large, and the data was exactly the kind (emails + explicit prompts) that ruins lives when it leaks. If you use Muah.ai, assume anything you type could appear next to your email in a future dump.

If you’re not comfortable with that (and most people shouldn’t be), Candy.ai is our pick for privacy-conscious users. It offers a comparable product with no breach history and real legal protections via GDPR. For Muah specifically, if you’re going to use it anyway, a throwaway email and virtual card are the minimum viable hygiene.
