HAPPO is a mental-health support app you can talk to — via voice or text, in nine languages, any hour. HAPPO is the friendly hippo who listens. She’s built on a stack of voice biomarkers, emotion analysis, and care-trained language models — but the experience is meant to feel like talking to a kind, patient friend, not a piece of software.

HAPPO is not a therapist and never claims to be. If you need clinical care, she’ll help you find a real human one.

Three groups, roughly: adults who want a private place to talk; families with kids aged 7+ who could use a kind ear; and schools, clinics, or workplaces that want to provide wellbeing support at scale.

Whichever you are, the door is the same — just pick your lane on the landing page.

No card, no email required for the first short conversation. You can be talking to HAPPO in under a minute. To save your conversation history or use voice analysis, you’ll be asked to make a free account.

iOS 16+, Android 12+, and any modern desktop browser (Safari, Chrome, Firefox, Edge). Voice features need microphone access, which we ask for the first time you use them.

Beyond conversations: day and week streaks, monthly-challenge badges, a personal calendar with add-to-phone, pause-and-resume practices, recurring routines with gentle check-ins, QR invites (including inside LINE), voice enrollment so HAPPO can tell speakers apart, a Team care dashboard with aggregate-only wellbeing, a HAPPO card after every voice check-in — and the Apple Watch app: breathing, sound baths, and check-ins from your wrist.

Your conversations are encrypted at rest (AES-256) and in transit (TLS 1.3), and access inside HAPPO is strictly limited to the few people who need it. We never sell your conversations, and we never hand them to anyone to use for their own purposes. Three named providers process them on our instruction, and only for as long as your request takes. Voice recordings are deleted once their acoustic features are extracted — the raw audio is not kept.

Exception: if HAPPO detects an imminent safety risk (active suicidal intent, ongoing abuse), she’ll surface emergency resources to you and — if you’re a child on a family plan — alert your parent with general context only.

No. We do not sell, rent, or share your data with advertisers. We do not run third-party trackers on the app. We don’t analyse your conversations to improve generic models. Privacy is the default; it is not a setting.

From your settings: tap "Delete history" → confirm. Conversations leave our active servers immediately and our backups within 72 hours. Account deletion is in the same place; it removes everything we hold, including your sparkle balance. The short-lived copies at our providers expire on their own clock, within about an hour, and we cannot shorten that.

Your account, your conversations and your analysis live in Singapore (asia-southeast1, GKE). An EU mirror is coming in Q3 2027 for European users. Two things travel briefly: your recording goes to Replicate for transcription and to Google for the reply, and your text goes to Anthropic. Those are United States companies, they receive nothing that says who you are, and what they receive expires within about an hour. We store nothing in mainland China.

If you’re in immediate danger, please call your local emergency line. HAPPO is not a crisis service. HAPPO will recognise crisis language and surface country-appropriate hotlines (Samaritans of Thailand, TELL Japan, etc.) within seconds. She’ll also stay with you while you reach out.

Thailand: Department of Mental Health hotline 1323 (free, 24/7). Japan: TELL Lifeline 03-5774-0992. Global: findahelpline.com.

No — and she won’t pretend to. Voice biomarkers and emotion analysis are context, not diagnoses. HAPPO will never tell you "you have anxiety" or "you have depression." If you want a clinical assessment, please see a clinician. She’ll happily help you find one.

On family plans, HAPPO escalates immediately to the parent via in-app alert + email — with general context ("Your child mentioned feeling unsafe today; please check in") but never the specific words. The child is also offered direct hotline access. We talked to a lot of kids while designing this; transparency about parental alerts is part of the system.

The Free Tier is ฿0, with 100 tokens a week. In the apps, packages run from ฿299/month (Me Plan) to ฿7,590/month (Team: Large Package), billed monthly by the App Store or Google Play. On the web you build your own group, priced per person by role: Me ฿199, family parents ฿399, children ฿199, team managers ฿499, members ฿199 — all monthly. See full pricing →

Yes — instantly, from your settings, no calls or emails required. You keep access until the end of your current billing period.

Email hello@happo.app. We have a quiet hardship programme — no questions asked, no income proof required. Mental health support shouldn’t depend on your bank balance.

Yes to all three, plus Thai PromptPay (via Stripe). International Visa/Mastercard/Amex work everywhere we ship.

Weekly trends, never transcripts. You see: whether your child has been engaging with HAPPO, and which practices they’ve been using. You do not see what they say — that’s sacred.

The only exception is safety alerts (see "What happens if a child says something concerning?" above).

7 and up. Below 7, kids generally don’t engage productively with text-based AI. Above 18 they should be on a personal plan, not a child account. Teens (13–17) get the same privacy protections as adults plus a more transparent parental-alert system.

In the apps, family packages go up to Family: Large Happy Family — 2 parents + 3 children — and an Apple or Google Play subscription cannot grow beyond that package. Web groups have no fixed size. If you subscribed through Apple or Google Play and need a bigger family, you would first end your store subscription, then subscribe again on the web.

At launch (May 2026): English, ไทย (Thai), 中文 (Chinese, simplified and traditional), 日本語 (Japanese), 한국어 (Korean), Bahasa (Indonesian + Malay), हिन्दी (Hindi), Français (French), Español (Spanish).

Coming in v2.0: Vietnamese, Tagalog, Tamil. Coming later: Arabic, Portuguese (BR).

Yes. HAPPO follows you — switch in your settings, or just start typing in another language and she’ll match you. Voice mode auto-detects spoken language as well.

Yes. Tonal languages (Thai, Mandarin, Vietnamese) have different pitch baselines than non-tonal ones. Our biomarker models are calibrated per-language to avoid false positives on the tonal swings that are just… tonal swings.

The pipeline is ours. HAPPO designed the orchestration and the multi-stage reasoning that turns a voice into a reading, grounded in our peer-reviewed research, and the analysis itself runs on our own self-hosted models: the acoustic side (pitch, energy, rhythm, pause) and the language side (stance, politeness, coherence) are both models we built and trained.

Two things run outside our own servers: turning speech into text, and writing HAPPO’s replies. Transcription uses Whisper, an open-source model, operated for us by Replicate. Replies are generated with Google Gemini and Anthropic Claude. Claude works only from text, so it never receives your recording. We send the recording and nothing else. No name, no account, nothing that says who you are. We never ask anyone to store it, and it expires on their side within about an hour. Your data is encrypted in transit and at rest, and you can delete anything HAPPO holds at any time.

Inside the app: settings → "Send feedback." Or email bugs@happo.app. We read every report. Security disclosures: security@happo.app — we run a quiet bug-bounty programme; details on request.
