Terms of Service

These Terms of Service (“Terms”) constitute a legally binding agreement between you (“you”, “your”, or “User”) and ACTASA GROUP LIMITED (“ACTASA”, “we”, “us”, or “our”), a company incorporated in the Hong Kong Special Administrative Region, governing your access to and use of the Tutor Wong (補習天王) platform, including the website at tutorwong.com, mobile applications on iOS and Android, and all related services and application programming interfaces (collectively, the “Platform” or “Service”).

By creating an account, accessing, or using the Platform, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy (available at the Privacy Policy page on our Platform). If you do not agree to these Terms, you must not access or use the Platform.

If you are accessing the Platform on behalf of an organisation (such as a tutor centre or educational institution), you represent and warrant that you have the authority to bind that organisation to these Terms, and references to “you” shall include both you individually and the organisation.

(a) You must be at least 18 years of age, or the age of legal majority in your jurisdiction, to create an account and enter into these Terms.

(b) The Platform is designed for use by parents, guardians, and tutors on behalf of children and students. Persons under the age of 18 may use the Platform only under the direct supervision of a parent or guardian who has accepted these Terms and assumes responsibility for the minor’s use.

(c) By creating an account, you represent and warrant that the information you provide during registration is accurate, complete, and current, and that you will update such information promptly if it changes.

(a) You may register an account using email and password credentials or through Google OAuth authentication.

(b) You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account, whether or not authorised by you.

(c) You must notify us immediately upon becoming aware of any unauthorised use of your account or any other breach of security.

(d) We reserve the right to suspend, disable, or terminate any account that we reasonably believe has been compromised, is inactive for an extended period, or is in violation of these Terms.

(e) Each account is personal and non-transferable. You may not sell, assign, sublicense, or otherwise transfer your account or any rights under these Terms to any other person or entity.

Subject to these Terms, the Platform provides the following AI-powered educational services:

(a) Homework Grading — upload photographs of handwritten or printed homework for AI-powered grading aligned with the Hong Kong curriculum across K1 to S6, covering Mathematics, English, Chinese, and other supported subjects.

(b) Step-by-Step Solutions — AI-generated explanations for incorrect answers, delivered in bilingual format (English and Traditional Chinese).

(c) AI Tutor — on-demand AI tutoring in text-based mode (instant written solutions) and video mode (animated tutorial videos with narration).

(d) Progress Analytics — per-child tracking of academic performance over time, including error pattern analysis (careless, conceptual, method, and incomplete working), topic-level proficiency, and trend identification.

(e) Adaptive Worksheets — AI-generated practice worksheets that target each child’s identified weak areas, with question difficulty adapted based on error type.

(f) Question Bank — a personal revision library of questions extracted and deduplicated from graded homework submissions, browsable by subject, grade, topic, and difficulty.

(g) Performance Reports — downloadable AI-generated summary reports analysing a child’s academic progress, strengths, weaknesses, and actionable study recommendations.

(a) The Platform offers multiple subscription tiers: Free, Basic, Pro, and Ultra. The features, usage limits, and pricing applicable to each tier are described on our pricing page and may be updated from time to time.

(b) All prices are quoted in Hong Kong Dollars (HK$) unless otherwise indicated.

(c) New paid subscriptions are processed through Apple App Store or Google Play in-app purchases. Stripe may continue to process legacy web subscriptions and historical billing records.

(d) By subscribing to a paid tier, you authorise us (or our designated payment processor) to charge the payment method on file for the subscription fees applicable to your selected tier at each billing cycle.

(e) We reserve the right to modify subscription pricing upon not less than 30 days’ prior written notice (via email or in-app notification). Price changes will take effect at the start of your next billing cycle following the notice period. If you do not agree to a price change, you may cancel your subscription before the new pricing takes effect.

(f) References to Unlimited in a paid tier mean ordinary personal, family, or tutoring use by a human user, subject to fair-use safeguards. Unlimited features do not permit automated scraping, bulk generation, resale, shared public access, classroom-scale batch processing, or other usage that materially exceeds normal household or tutoring use.

(g) Pro unlimited grading and step-by-step solution features are subject to daily fair-use caps of 40 grading submissions per day and 20 solution requests per day. Ultra unlimited features do not have a published daily quota, but remain subject to platform rate limits, anti-abuse controls, and reasonable throttling or temporary restriction where usage is automated, resale-oriented, shared with unauthorised users, or threatens service quality for other users.

(a) The Free tier provides limited access to the Platform, including up to 20 homework grading submissions per month, subject to a daily cap of 2 submissions, and up to 1 child profile.

(b) The daily Free tier quota resets at 1:00 AM Hong Kong Time (HKT, UTC+8) each day.

(c) We reserve the right to modify the features, limits, or availability of the Free tier at any time without prior notice.

(a) Subscription fees are charged in advance at the beginning of each billing period.

(d) For in-app purchases made through Apple App Store or Google Play, the respective platform’s payment terms, billing practices, and refund policies apply in addition to these Terms.

(a) You may cancel your subscription at any time through your account settings on the Platform, via the Stripe customer portal, or through the subscription management features of the applicable app store (Apple or Google).

(c) We do not provide pro-rata refunds for partial or unused portions of a billing period.

(d) Refund requests based on exceptional or extenuating circumstances may be submitted to us via the Contact page and will be considered on a case-by-case basis at our sole discretion.

(b) Bonus credits are subject to expiration dates (where applicable) and may only be redeemed in accordance with the programme rules displayed on the Platform.

(b) You retain ownership of your User Content.

(d) We may use anonymised and aggregated data derived from User Content (such as question types, common error patterns, and academic trends) to improve our AI models, algorithms, and overall Service quality. Such aggregated data will not identify any individual user or child.

(a) THE PLATFORM USES ARTIFICIAL INTELLIGENCE, INCLUDING LARGE LANGUAGE MODELS AND COMPUTER VISION MODELS, TO ASSIST WITH HOMEWORK GRADING, SOLUTION GENERATION, TUTORING, WORKSHEET CREATION, AND PERFORMANCE ANALYSIS. ALL AI-GENERATED OUTPUT IS PROVIDED ON AN “AS IS” BASIS AND MAY CONTAIN ERRORS, INACCURACIES, OMISSIONS, OR HALLUCINATIONS.

(b) AI grading results, solutions, error analysis, and reports are advisory and supplementary in nature. They do not constitute professional educational assessment, official academic certification, or formal examination marking.
