Terms of Service

Article 1 (Scope)

1. These Terms apply to all relationships between us and users concerning the use of the Service.
2. Purchases of paid services are also governed by the seller's purchase terms (Purchase Terms (JPY/USD) or Purchase Terms (TWD)). If the purchase terms and these Terms differ, the purchase terms prevail for purchases, payments, points and refunds.
3. The Plans page and other explanations we publish in the Service form part of these Terms.

Article 2 (Definitions)

• "User": anyone who uses the Service, including people without an account
• "Member": a user who has registered an account

• "AI-generated content": scan results, readings, translations, explanations, questions, answers, audio, reports and other information the Service generates using AI
• "Points": the unit that measures use of features involving AI processing
• "Seller": the seller of paid services (us for purchases in JPY or USD; 哇哇科技股份有限公司 for purchases in TWD)

Article 3 (Accounts)

1. You register with an email address or an account from an external service we accept. Keep your registration information accurate and up to date.
2. An account may be used only by the person who registered it, for their own learning. You may not let others use, lend, transfer, sell or share your account.
3. You are responsible for keeping your login details safe. If you learn that someone else is using your account without permission, contact us immediately.
4. To prevent misuse, we may limit the number of devices that can be signed in at the same time and the number of simultaneous lessons, and may ask you to sign in again, for example after logins from several countries in a short time.
5. Minors must have a parent's or legal guardian's consent to use the Service.

Article 4 (The Service)

1. The Service offers Japanese-learning features such as scanning Japanese materials you photograph or upload, translations, readings, read-aloud, quizzes, review, a dictionary, kana and other practice, lessons with an AI Sensei (voice and text) and writing checks.
2. Some features are free; others require a paid service or points. Features and conditions are shown on the Plans page.
3. We may add or change features to improve the Service. Changes to paid services that are unfavorable to users follow the procedures in the purchase terms.

Article 5 (Use of AI and AI-generated content)

1. The Service uses AI provided by OpenAI, L.L.C. and other companies. For AI processing, your content (including photos, text and audio) is sent to those companies. See the Privacy Policy for details.
2. The Senseis in the Service (such as Haruka-sensei) are AI, not humans. The Service shows "AI" next to their names.
3. AI-generated content is part of the Service's learning materials. We are responsible for keeping the materials accurate, and when we are told about an error (through "Report wrong reading" or by email) or otherwise learn of one, we will correct or remove it promptly. Correction deadlines and point refunds for users of paid services follow the purchase terms.
4. We do not guarantee that using the Service will lead to passing any particular exam.
5. You may freely use AI-generated content for your own learning.
6. Shared explanations: questions you enter in "Ask by text" and "Highlight explanation", and the AI's answers (except answers personalized for you), are stored as shared explanations in a form that does not identify you, and are reused to answer users (including you) who ask the same question. Word meanings and example sentences taken from them may be added to the dictionary. Writing checks, web page summaries, the content of your photos and pages, and lesson content are not stored as shared explanations.
7. We do not use your content to train AI models.
8. If you use a feature paid with your own OpenAI key, the key is stored in your device's browser and is not sent to or stored on our servers. (If we later offer to keep keys for you, we will explain it separately and ask for your consent.)

Article 6 (Fees and points)

1. Free features and free points are shown on the Plans page. Free points cannot be exchanged for cash or transferred.
2. Prices, points, cancellation and refunds for paid services follow the purchase terms.
3. Points cannot be moved between accounts and expire when you delete your account. However, you can request a refund of unused paid points that are refundable under the purchase terms before deleting your account.

Article 7 (Your content)

1. Copyright and other rights in your content remain with you or the rightful owner.
2. You warrant that you own the rights to your content, have the necessary permission from the rights holder, or are using it within a lawful scope such as private use under copyright law. Upload photos of textbooks, workbooks and books only as needed for your own study.
3. You grant us a free license to copy, adapt, transmit and store your content to the extent needed to provide and maintain the Service (including AI processing, sending it to our service providers, and investigating problems). We do not publish your content without your permission.
4. If we receive a claim that your content infringes a third party's rights and reasonably judge that it may, we may delete all or part of it or make it unavailable. Send infringement claims to max@wowwow.tw.
5. If you upload a photo showing personal information such as a name or address, cover those parts as needed.
