Anonymous mental health apps: an honest guide
"Anonymous" is doing a different job in every app that claims it. Here are five questions that tell you which kind you're holding — and how today's apps answer them.
Search for a mental health app and you'll see the word everywhere: anonymous. It's on store listings, landing pages, privacy summaries. And it's rarely a lie, exactly. It's just that the word is doing a different job in each one — sometimes "we don't show your name to other users," sometimes "you can skip the email box," and only occasionally "we couldn't identify you if we tried." Those are very different promises, and in this category the difference matters more than almost anywhere else.
Before we go further: we make one of these apps, and anonymity is one of the hills our product stands on — so we are not neutral. What we can do is give you the questions we think any app in this space should be able to answer, let the answers speak for themselves, and include ourselves in the line-up on the same terms.
Why anonymity matters more here
The active ingredient in talking about your mental health — to a person or to an AI — is candour. It only works if you say the true thing, and people reliably don't when they suspect it's attached to their name. That's not paranoia; it's a well-documented chilling effect, and everyone who has hesitated before typing something real into a box on the internet has felt it.
And the caution is earned. In 2023, the US Federal Trade Commission reached a $7.8 million settlement with BetterHelp — one of the biggest names in online therapy — over sharing the email addresses and health-questionnaire answers of people seeking counselling with Facebook and other platforms for advertising. Not a shadowy data broker: a household name, with data people gave it at their most vulnerable. The lesson isn't that every company behaves that way. It's that when identity and intimate content live in the same database, the only thing standing between them and misuse is policy — and policy changes, gets breached, or gets subpoenaed.
Anonymity done properly removes that whole class of problem. If the identity was never collected, it can't be leaked, sold, or demanded.
Five questions that cut through
1. What must you hand over before the first conversation? An email address? A phone number? A name? Every field on that first screen is something that can later be joined to what you say. The best answer is: nothing that identifies you.
2. Is who-you-are stored next to what-you-said? This is the structural question. Some apps collect your identity but keep it separated from your content; some keep them in the same record; the strictest never have an identity to store at all. Privacy policies usually reveal this if you read them slowly.
3. Who else is in the room? Analytics SDKs, ad trackers, attribution tools — many wellbeing apps quietly include several. Each is a third party learning something about a person who thought they were alone. "Zero third-party trackers" is a sentence an app can simply say, if it's true.
4. What does delete actually delete? "Delete account" ranges from a full purge on a timer to a soft flag that hides your data from you but not from them. Look for a stated erasure window and an export option — an app that lets you take your history and walk away is showing you who it is.
5. If they were breached tomorrow, what would link to your name? This is the question that summarises the other four. Breaches happen to careful companies. The honest measure of an app's privacy isn't its intentions — it's what an attacker would actually get.
How the current apps answer
The anonymity-first apps — and there have been several — deserve a candid note: this corner of the market has proven fragile. More than one app that led with "no sign-up, fully anonymous" has folded or entered wind-down in the past couple of years, taking its users' histories with it. That's not an argument against anonymity; it's an argument for question four. Before you give any app — including ours — months of your private record, check you can export it and walk away. An anonymous app that can't outlive its funding round protects your identity right up until it loses your history. It's the same lesson Woebot's shutdown taught the whole category, at larger scale.
The small no-login web chatbots — there's a rotating cast of them — are anonymous in the simplest sense: a text box, no account. Some are sincere projects. But most publish no evidence base, no crisis design, and no clear story about where your words go or how the service is funded, and a free service with no visible business model is a question worth sitting with. Anonymity isn't worth much if the transcript itself travels somewhere unstated.
General AI chatbots (ChatGPT and friends) are where a lot of this conversation actually happens now, but the anonymity isn't there: you're signed in, history is saved to your account by default, and the operators are explicit that conversations may be reviewed for safety. For thinking out loud about a work problem, fine. For the things you'd only say anonymously, it's the wrong tool by design.
Nagi — ours, so judge this paragraph with that in mind. We built Nagi & Me to give the strictest available answer to all five questions: we never ask for an email, phone number, or name — account recovery works through a code only you hold; there is no identity stored next to your words because none is collected; there are zero third-party trackers or analytics SDKs in the app; you can export everything or erase everything, with erasure completed within 30 days; and a breach of our systems would expose words with no name attached. Data lives on UK/EU-hosted infrastructure. There is one honest asterisk — if you subscribe, Google or Apple know you bought a subscription, though that payment identity is never joined to what you say — and we've written up exactly how the separation works, plus the full detail in our privacy policy.
The caveat that keeps this honest
Anonymity is not the same thing as helpfulness. An anonymous app can still be a poor companion, and an identified one can still do you real good — plenty of people get genuine value from apps that know exactly who they are. Privacy is one axis. Whether the thing actually helps you notice, untangle and steady yourself is another, and you only learn that by using it.
And whatever any of these apps say about privacy, none of them — ours included — is therapy, and none is a crisis service. Anonymity is for the everyday truth-telling that keeps you well. For the moments beyond that, the numbers at the bottom of this page are staffed by humans, and they're free.
