Terms of Use

Last updated: 10/8/2025

Please read the following terms and conditions carefully before subscribing to "Card0 Pro" or "Card0 Max," services provided by "Card0" ("we," "us," "our") (the "Service").

Subscription

The Service is subscription-based and fee-based, meaning you will be charged in advance for future subscription usage. Currently, you may choose annual or monthly billing cycles.

Unless canceled, your subscription will automatically renew at the end of each cycle. You can manage or cancel automatic renewal through your Apple ID account settings, or we may cancel the service at our discretion.

Free Plan

  • New users may receive a limited free plan that allows access to basic features and a small number of credits.
  • The free plan is intended for trial purposes only and does not automatically upgrade to a paid subscription.
  • We reserve the right to adjust the availability, duration, and features of free access for better service delivery.

Fees

  • Subscription fees are billed through your Apple ID account.
  • If a price adjustment occurs, the new fee will be applied in your next billing cycle.
  • All payments and subscriptions are processed securely via Apple’s App Store in cooperation with our billing partner, RevenueCat.

Card0 Pro & Card0 Max

We currently offer the following subscription tiers:

  • Card0 Pro Monthly: 2,000 credits per month
  • Card0 Pro Annual: 2,000 credits per month (billed annually)
  • Card0 Max Monthly: 8,000 credits per month
  • Card0 Max Annual: 8,000 credits per month (billed annually)

Pricing may vary by region and during promotional periods. All Credits shall expire in accordance with our Credit Policy as may be updated from time to time.

Credit System

  • Credits are refreshed monthly based on your subscription tier.
  • Credits are consumed when using AI-powered or premium features. For AI-powered features, the specific credits consumption for a task is determined by its complexity and duration. Examples:
    • Create 20 cards with AI: Credits used 20
    • Introduce Game Rule: Credits used 15
    • Creating a new game: Credits used 35
  • Unused credits do not roll over to the next month.
  • Credits are non-transferable, non-refundable, and may only be used by the account that received them.
  • We reserve the right to modify the number of credits required for specific features or services to reflect operational costs, system demand, or new feature releases.

If credits are obtained or used fraudulently, we may invalidate them and take appropriate action, including suspension or termination of your account.

Fair Use Policy

Our goal is to ensure high-quality service for all users.

  1. Usage Limits
    • Unlimited usage claims are subject to “reasonable use” standards.
    • Automated scripts, malicious software, or abuse of the system are prohibited.
  2. Determination of Fair Use
    • We may use algorithms or manual review to determine whether usage exceeds typical patterns.
  3. Consequences
    • If your usage exceeds fair use, we may limit, suspend, or adjust your access.
    • We will attempt to notify you before taking such actions.
  4. Policy Updates
    • We may update this Fair Use Policy at any time. Changes will be posted in the App or on our website.
