Common questions.
The answers to what most people ask. If yours isn't here, get in touch .
Getting started
What does ThaiDai actually teach?
A curated Thai vocabulary deck for English speakers — currently 2,400+ entries and growing toward 3,000, plus a native-trained Thai voice on every word, eight grammar lessons, and 15 scripted dialogues. The voice and editorial register are aimed at people who actually live in or visit Thailand — not classroom Thai. Live counts on /stats.
Do I need to know any Thai before I start?
No. The free tier covers 172 daily-survival essentials and includes the foundational lessons (greetings, polite particles, numbers, basic verbs). The /resources hub has a free getting-started guide that walks through the daily-practice loop.
How long does it take to learn enough Thai to be useful?
Three to six months of daily practice gets you to "useful in Thailand" — ordering food, taking taxis, basic shop transactions. Six to twelve months gets you to conversational. We have a longer write-up in /resources/how-long-to-learn-thai.
Pricing + tiers
What does the free tier include?
172 daily-survival essentials including audio, the full /resources article library, all eight grammar lessons, four free dialogues, and the daily-practice loop with a 20-card daily cap. Free is genuinely usable, not a teaser.
What does Pro unlock?
The full corpus (currently 2,400+ entries, growing to 3,000), all 15 dialogues, no daily cap, and any future content (we ship roughly bi-weekly). Pro is $14.99 monthly, $99 annually, or $199 lifetime. The tier explainer at /resources/how-tiers-work covers it in detail.
Is there a refund?
30-day no-questions-asked refund on any plan. After 30 days, refunds are at our discretion — usually fine if the reason is reasonable.
What payment methods do you accept?
Card payments via Stripe (Visa, Mastercard, Amex). Apple Pay and Google Pay also work via Stripe. We don't store card details — Stripe handles that.
Audio + pronunciation
Where does the audio come from?
A native-trained Thai voice. We pre-cache the free-tier audio and generate Pro audio on first request, then cache it. The voice is consistent across the corpus so the audio sounds like one speaker, not a patchwork.
Do you have a male voice option?
Currently female voice only. Male voice is on the roadmap (PR 15 in the workstream docs) — we want to ship a high-quality second voice rather than a quick-and-dirty option.
Account + data
Why magic-link only? Why no password?
Passwords get reused, leaked, and forgotten. A magic link is one-shot, expires in 15 minutes, and means we never store a password. The trade-off is a small friction on every sign-in — for a learning app you use most days, that's fine.
Can I export my progress?
Yes. /settings → Export account data downloads a JSON file with your word_progress, lesson mastery, streak, XP, and any account metadata. We don't use it ourselves; it's for you.
How do I delete my account?
/settings → Delete account. Cascades all per-user rows (word_progress, sessions, lesson_mastery). Stripe billing records are retained for accounting, per UK / EU law. If you're mid-subscription, cancel via Stripe first or contact support.
Do you sell my data? Use it for AI training?
No to both. We don't sell, share, or use anyone's usage data for training third-party models. The only third party that touches your email is Resend (transactional sends) and Stripe (billing). The /privacy page covers exact data flows.
Technical + product
Is there an iOS / Android app?
Not yet. The web app is mobile-friendly and works as a PWA — you can add it to your home screen. Native apps are post-launch, after we've validated the web product.
Why does my deck reset every day?
It doesn't — your progress is permanent. The 20-card daily cap on free is a fresh slice of your unlocked vocabulary chosen by spaced repetition, not a reset. Pro removes the cap.
I found a bug / wrong tone / typo. What do I do?
Use /contact below. Include the word ID or article slug if possible. We fix tone errors fast — wrong tone is wrong word, and that is a learner-facing problem we take seriously.
