2. Description of Service

ITF TKD Theory provides educational content, quizzes, and study materials related to International Taekwon-Do Federation (ITF) theory, philosophy, and principles. Our service is designed to help martial arts students prepare for belt examinations and deepen their understanding of ITF Taekwondo.

The service is offered under a free tier with limited features and one or more paid tiers ("Pro" subscriptions and the one-time "Grading Pass") that unlock additional, "gated" tools described in Section 4.

• Pro Monthly – $6.99 per month, auto-renewing until cancelled.
• Pro Annual – $39 per year, auto-renewing until cancelled.
• Grading Pass – $9.99 one-time payment granting 90 days of Pro access. This is not a subscription and does not auto-renew.

We may change plan names, pricing, included features, or introduce additional plans at any time. Any change to a recurring price will not take effect for your current billing period and you will be notified before the next renewal.

4.2 Gated (Pro-Only) Features

The following tools are gated behind an active Pro subscription or Grading Pass and are not available on the free tier:

• AI Tutor – conversational AI assistant for ITF theory questions, with retrieval-augmented citations from the Encyclopedia. Free users are limited to a small number of messages per day; Pro users receive a substantially higher monthly allowance.
• Full Pattern Library (Dan-Grade Patterns) – access to all 24 patterns, including the 15 advanced Dan-grade patterns. The free tier is limited to the 9 colour-belt patterns.
• Smart Review (Spaced Repetition) – AI-driven flashcard system using a spaced-repetition algorithm to target weak areas.
• "Explain This Answer" on Quizzes – personalised, source-cited explanations of incorrect quiz answers.
• Printable PDF Study Sheets – downloadable pattern guides and grading packs for offline study.
• AI Grading Plan – AI-generated, multi-week preparation plan tailored to your next belt grading, including XP, streaks, and badges.
• Conditioning & Mobility Plans – rank-tuned stretching, strength, cardio, and recovery recommendations.
• Full-Year Quiz Heatmap & Weak-Area Analytics – activity calendar and performance drilldowns across your full quiz history.
• Unlimited Practice and Match Drill Sessions – unrestricted access to Practice Mode and the Korean terminology Match Drill.

The list of gated features may change over time as we add, remove, or restructure tools. Where reasonably possible we will keep the in-product feature comparison and this section aligned, but the in-product display at the time of purchase shall govern what is included.

4.3 Billing and Payment Processing

• Payments are processed by our third-party payment processor, Stripe. We do not store full payment card details on our servers.
• By purchasing a paid plan, you authorise us (via Stripe) to charge your selected payment method for the plan price, applicable taxes, and any renewal amounts.
• You are responsible for keeping your payment information accurate and up to date.

4.4 Auto-Renewal and Cancellation

• Pro Monthly and Pro Annual subscriptions renew automatically at the end of each billing period at the then-current price for that plan until you cancel.
• You may cancel at any time via the Stripe customer portal accessible from your account. Cancellation takes effect at the end of the current paid billing period; Pro features remain available until that date.
• The Grading Pass is a one-time purchase and does not auto-renew. Access ends automatically after 90 days.

4.5 Refunds

• Except where required by applicable law (including statutory consumer rights in your jurisdiction), all payments are non-refundable.
• We may, at our sole discretion, issue partial or full refunds in cases of duplicate charges, prolonged service outages, or billing errors. Contact us using the details in Section 19.

4.6 Loss of Access
