Terms of Service

Effective 30 August 2026 · applies to learnthai.app, app.learnthai.app and hebrew.learnthai.app

learnthai.app (“the app”) is a language-learning game run by its developer, an independent individual (“we”). By using the app — and again, explicitly, when you sign in — you agree to these terms and to the Privacy Policy. If you don’t agree, don’t use the app. Contact: privacy@learnthai.app.

1 · Who may use it

You must be at least 13 years old — or older where your country sets a higher minimum age for consenting to online services — to use the app or create an account. The app is not directed at children.

2 · Accounts

Signing in takes only an email address; a 6-digit code sent to it is the whole login. Whoever can read that inbox can enter the account, so keeping the inbox secure is on you, and activity under your session counts as yours. You can delete your account at any time from the bottom of ⚙️ Settings, which permanently erases it and everything synced to it. We may suspend or close an account that breaks these terms.

3 · The service, and how it can change

The app is free to use today. Some features are metered — Kru, the AI teacher, and feedback reports have daily allowances — and those allowances, like any feature, can change, pause, or end as the project evolves. We work on the app continuously and can modify or discontinue parts of it; nothing here obliges us to keep any feature running, though your progress remains yours to delete or leave at any time.

4 · Fair use

Don’t abuse the app or the people behind it. In particular, don’t:

probe, overload, or work around rate limits, quotas, or authentication;
scrape, bulk-download, or republish the app’s content outside the licenses in section 7;
use Kru or the feedback form to submit unlawful content, to harass, or to attempt to make the AI produce content unrelated to learning languages;
misrepresent who you are when signing in or filing reports.

5 · What you send us

Questions to Kru and feedback reports are yours, but you give us the right to use them to operate, debug, and improve the app. Don’t include personal details about yourself or anyone else — a report about a wrong translation never needs them.

6 · AI answers and content accuracy

Kru is an AI teacher, built on Anthropic’s Claude models, and its answers are machine-generated: usually helpful, sometimes wrong, occasionally confidently wrong. The deck itself — translations, romanizations, audio, example sentences — is produced by a pipeline that mixes dictionaries, synthesized speech, and machine judgment, checked but not infallible. Treat all of it as a study aid, not an authority: verify anything that matters, and expect no guarantee of learning outcomes. It is not professional advice of any kind.

7 · Content and licenses

Dictionary data comes from Wiktionary via kaikki.org, under CC BY-SA. The card dataset the app serves is a derivative of it and is likewise available under CC BY-SA 4.0 (attribution: Wiktionary contributors, kaikki.org, learnthai.app).
Photos are from Pexels and Pixabay under their respective licenses, credited per image; some illustrations are AI-generated.
Audio is synthesized speech (Google Cloud Text-to-Speech and ElevenLabs voices).
Fonts (Sarabun, Noto Sans Thai) are used under the SIL Open Font License.
Everything else — the app’s code, design, lessons, and curated content — is © the developer. You may use the app for personal study; you may not resell or redistribute it.

8 · No warranties

The app is provided “as is” and “as available”, without warranties of any kind, express or implied — including fitness for a particular purpose, accuracy, and uninterrupted availability — to the maximum extent the law allows.

9 · Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost data, profits, or goodwill, arising from your use of the app. Our total liability for any claim is capped at the greater of what you paid us in the twelve months before the claim (today: nothing) or US $20. Nothing in these terms limits liability that cannot lawfully be limited, or the mandatory consumer rights of the place you live.

10 · Termination

You can stop using the app, or delete your account, at any time. We can suspend or terminate access that violates these terms or harms the service; sections 5–9 survive termination.

11 · Changes to these terms

When these terms change, this page changes, with a new effective date; material changes will be flagged in the app. Using the app after a change takes effect means you accept it.

12 · Governing law

These terms are governed by the laws of Israel, and disputes belong to the competent courts in Israel — except where the law of your country of residence mandatorily gives you the right to something else.
