HAPPO is a mental-health support app you can talk to — via voice or text, in nine languages, any hour. Dr 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 Dr 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.

Nobody but you. Conversations are encrypted at rest (AES-256) and in transit (TLS 1.3) with a key derived from your account password. Our employees cannot read your messages, even if they wanted to. We physically cannot share them with anyone.

Exception: if Dr 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, including your sparkle balance.

Singapore (asia-southeast1, GKE). An EU mirror is coming in Q3 2026 for European users. We do not store data in mainland China or the United States. Audit reports available on request for Team-plan customers.

If you’re in immediate danger, please call your local emergency line. HAPPO is not a crisis service. Dr 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. Dr 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, Dr 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.

Free forever, with 100 sparkles per week. Personal is ฿700/month. Family is ฿2,700/month for up to 6 accounts. Team is custom. 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 and major Asian payment networks (LINE Pay, GrabPay, KakaoPay). International Visa/Mastercard/Amex work everywhere we ship.

Weekly trends, never transcripts. You see: mood patterns over the week, sleep quality, whether your child has been engaging with Dr 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.

Family plan covers 1 parent + 4 children. If you have more, the easiest path is to add a second family plan, or contact us about a custom multi-family arrangement.

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. Dr 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.

Fine-tuned HAPPO.ai-class models for conversation, Whisper for voice transcription, and a small in-house biomarker classifier built on openSMILE. Conversation mode does not call external LLM providers — everything runs in our own infrastructure.

Some of it. Our voice-biomarker pipeline is open source at github.com/happo/voice-biomarker (Apache 2.0). The conversation models, training data, and Dr HAPPO’s care logic are proprietary. We may open-source more over time.

Not yet publicly. Team-plan customers can request a webhook-based API for aggregate analytics. A broader public API is on the roadmap for late 2026.

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.
