Fair use of a fan-built tool.
These are development-stage terms and will be professionally reviewed before public launch or payment collection.
The service
CardSuDon provides game-specific card discovery, collection records, and indicative analytics. Prices may be delayed, incomplete, or incorrect and are not offers, guaranteed sale proceeds, or financial advice. Verify price, condition, stock, shipping, and seller terms before purchasing.
Your account
Provide accurate information, protect your credentials, and do not misuse the service, automate excessive requests, interfere with other users, or upload unlawful content. You retain ownership of information you enter.
Research contribution
Community analytics is governed by a separate optional consent. Declining it does not prevent normal account use. Aggregate outputs may be used in free or paid market reports only under the safeguards in the Privacy Notice.
Supporter subscription
When payments are enabled, CardSuDon Membership costs S$0.99 per month and renews automatically until cancelled. The checkout page shows the price before payment. Subscribers can cancel through the billing portal; access continues until the end of the paid billing period. Payment disputes and refund requests will be handled under applicable Singapore consumer law and the policy displayed at checkout.
Retailer preview
The retailer programme remains a separate approval waitlist. No retailer fee will be collected until Riot Games and relevant data providers approve the intended use. Preview examples are illustrative and are not live market claims.
Fan-project status
CardSuDon is an independent multi-TCG prototype. Each game section remains unofficial and subject to its publisher's applicable policies or approval. It is not endorsed or sponsored by Riot Games. Third-party names, card content, and data remain the property of their respective owners.
