Terms of Service

Effective: 10 June 2026 · Provider: Malggu, [Your registered business address — update in Framer] · Contact: support@malggu.com

These Terms govern your use of Malggu websites and digital learning products (malggu.com, market.malggu.com, wordbook.malggu.com, and related apps). By creating an account, redeeming a key, or purchasing, you agree to these Terms and our Privacy Policy.

1. What we sell & provide

Digital Korean learning products and related Services, including:

• PDF/wordbook content and audio sold via Polar (with redeem keys by email)
• GIF wordbook, quizzes, and progress tracking on wordbook.malggu.com
• Magic Motion / grammar spell games using optional camera-based motion detection
• Korea Simulation — map-based language practice, landmarks, and partner venue features (some sponsored — labelled in-app)
• Malggu Grammar Master Chrome extension — grammar spotting, dual captions helpers, frequency/practice on Netflix and YouTube while you watch. Dialogue/subtitle text is processed in your browser for matching and is not stored as episode scripts on our servers
• Optional AI tutor (text and/or voice), mistake review, and learning reports powered by third-party AI APIs

Each product page describes what is included. Access is licensed to you — not sold as physical goods.

2. Account & age

You must provide accurate email information and keep your password secure. One account per person unless we approve otherwise.

You must meet the minimum age confirmed at signup: 16+ (or your country's minimum for online services — e.g. 13 in some US/EU contexts with parental rules, 14 in Korea with guardian consent for under-14s). We may close accounts that violate age requirements.^{[KR-22-2][EU-8][US-COPPA]}

3. Purchases, payment & redeem

Checkout is processed by Polar (polar.sh), our payment and license partner. Prices are shown before payment. Taxes may apply. After payment, a license/redeem key is sent to your email. Redeem at market.malggu.com/redeem using the same email as checkout to unlock digital entitlements on your account.

By redeeming or downloading digital content, you acknowledge that delivery of the digital product may begin immediately, which can affect withdrawal rights where applicable (see Section 5).^{[KR-EC][EU-DIG]}

4. License & use

We grant you a personal, non-exclusive, non-transferable license to use purchased content and linked games for your own learning. You may not resell, redistribute, scrape, or publicly share files except where a product explicitly allows it.

5. Refunds & withdrawal

EU/UK consumers: where law gives a 14-day withdrawal right for digital content, you may lose that right once download, streaming, or account activation begins if you gave prior express consent and acknowledged the loss of the right.^[EU-DIG]

Korea: for digital content, withdrawal may be restricted once provision has begun, provided we clearly disclosed this and you consented (Electronic Commerce Act).^[KR-EC]

If content is defective or not as described, contact support@malggu.com within 14 days of purchase. Refunds are handled per Polar policy and mandatory consumer law in your country. Optional marketing gifts (e.g. free starter PDF) do not affect statutory rights on paid products.

6. Marketing gifts

Optional marketing consent may include a free digital gift (e.g. starter PDF). This is not required to use Malggu or buy products. Refusing marketing does not block signup or purchase.^{[KR-22-5][EU-7]}

6A. Grammar Master Chrome extension

Grammar Master helps you notice Korean grammar while watching Netflix or YouTube. The extension may read on-screen captions and playback time in your browser to match grammar, show frequency, and jump to practice moments.

We do not claim affiliation with Netflix or YouTube. Their terms and policies still apply. We do not provide or resell episode scripts.

Explain unlock: unlimited grammar explanations may be available if you (a) have an active paid Malggu membership that includes that benefit, or (b) have consented to Malggu marketing emails (including via our PLF / squeeze email list where applicable). If you withdraw marketing consent or unsubscribe, unlimited Explain may lock again unless you have a qualifying membership. Matching, frequency, and basic practice features remain available as described in the product.^{[KR-22-5][EU-7]}

Membership may add separate features such as study history, quizzes, and AI practice — as shown in the product — and is not the same as marketing consent.

Optional sense feedback: you may tap controls such as “this meaning fits” / “other meaning” to improve on-device sense selection. That feedback may be used to improve Malggu's dictionary sense ranking. We do not use Netflix or YouTube dialogue text for that purpose. Feedback first improves your device; if you are signed in, limited metadata (lemma, sense index, short gloss, vote) may sync to your account for product improvement. Separately, the extension may record anonymous, account-free counts of which dictionary headwords are opened or heard (never captions or dialogue) so we can improve the lexicon.^[KR-15]

7. Acceptable use

No abuse, hacking, automated scraping, harassment in simulation or AI chat, or infringement of others' rights. Do not misrepresent sponsored venues as official government or travel guidance. Do not attempt to jailbreak or misuse AI features for unlawful content. Do not use Grammar Master to bulk-download, redistribute, or build a competing subtitle/script database from Netflix or YouTube. We may suspend accounts that violate these Terms or law.

8. Interactive games (Magic Motion & Simulation)

Magic Motion / camera games: camera access is requested only when you enter a camera-enabled game, with a separate consent step. Video is processed on your device; we do not store raw video by default. You may use non-camera alternatives where offered. See Privacy Policy §11.^[KR-ICT]

Korea Simulation: maps, dialogues, and venue listings are for language learning and entertainment. Sponsored or partner locations are labelled. They are not immigration, employment, or safety advice. Real business offers are subject to the partner's terms.^[KR-AD]

No professional advice: Malggu does not guarantee exam results, fluency timelines, or real-world outcomes. Games supplement — do not replace — formal instruction where required.

9. AI tutor, voice (STT) & learning data

AI tutor: optional text and/or voice features may send your messages and limited learning context (e.g. mistakes, progress) to OpenRouter (United States), which may route them to underlying model providers (e.g. OpenAI or Anthropic families), to generate replies and help create learning reports. First use requires a separate in-app consent. See Privacy Policy §§13–14.

Voice: microphone audio is transcribed by Groq Whisper STT (United States); spoken replies may use Google Cloud Text-to-Speech. We do not store raw microphone audio by default. STT may mishear mixed Korean/English speech. You may use text chat instead.^[KR-ICT]

Not professional advice: AI output can be inaccurate or incomplete. Malggu AI is for language learning only — not medical, legal, immigration, investment, or other professional advice. Do not rely on AI for exams, official documents, or high-stakes decisions.

Your responsibility: do not submit or speak passwords, payment details, government IDs, or other highly sensitive data into AI or voice features.

10. Availability & changes

We aim for reliable service but do not guarantee uninterrupted access. We may update content, features, or these Terms. Material changes will be posted on the site. Consent-based features (marketing, analytics, camera, AI tutor, voice) require separate consent under the Privacy Policy.

11. Liability

To the fullest extent permitted by law, we are not liable for indirect or consequential loss. Nothing limits liability for death, personal injury, fraud, or rights that cannot be limited under consumer law.

12. Governing law

These Terms are governed by the laws of England and Wales, without regard to conflict-of-law rules. Courts in that jurisdiction have exclusive jurisdiction except where consumer law requires otherwise. EU/UK/Korean consumers keep mandatory protections in their country of residence.
