Last Updated: January 10, 2026

1. Introduction and Acceptance of Terms

These Terms of Service (“Terms”) govern your access to and use of Callirra, an AI-powered image and video generation platform operated by Chen Hongtao as an individual developer (“we,” “us,” or “our”). The Service is available at https://callirra.com.

By creating an account, subscribing to any plan, purchasing credits, or otherwise using the Service, you confirm that you: (a) are at least 18 years of age; (b) have read, understood, and agree to be bound by these Terms; (c) agree to our Privacy Policy; and (d) are authorized to enter into this agreement on behalf of yourself or any organization you represent.

If you do not agree to these Terms, you may not use the Service. Continued use after any update constitutes acceptance of the revised Terms.

2. Service Description

Callirra provides a unified SaaS platform that enables users to generate images and videos using third-party AI models, organize generated assets, and manage credits and subscriptions. The Service is a digital, intangible product delivered via the internet. Access is granted immediately after confirmed payment.

Callirra is an independent platform. Model names and trademarks belong to their respective owners. Callirra is not affiliated with, endorsed by, or sponsored by the model creators listed on this site.

2.1 Underlying AI Models

Callirra uses mainstream third-party AI models, including but not limited to Seedance (ByteDance), Kling (Kuaishou), MiniMax H3 (MiniMax), Veo (Google), Gemini Omni (Google), GPT Image (OpenAI), Nano Banana (Google), Seedream (ByteDance), Grok Imagine (xAI), Z-Image (Tongyi), Hailuo (MiniMax), HappyHorse. The exact set of models available can change; the current model selector in the generation UI always shows the live choices.

3. Account Registration and Eligibility

To use the Service, you must create an account with accurate and complete information. You are responsible for maintaining the confidentiality of your login credentials and for all activities under your account. Notify us immediately at support@callirra.com if you suspect unauthorized use.

The Service is intended for users aged 18 and above. If you register on behalf of a company or organization, you represent that you have authority to bind that entity to these Terms.

4. Plans and Credits

Callirra operates on a credit-based system. Subscriptions grant a recurring monthly credit allowance, and one-time credit packs add extra credits that remain valid according to the pack terms. The current plans, prices, and credit amounts are shown on our pricing page.

  • Subscription credits are reset at the start of each billing period and do not carry over unless stated otherwise.
  • Credit packs are valid for the period shown at purchase (typically 12 months).
  • Consumed credits are not refundable; unused credits may be refundable under Section 7.

5. Billing and Payment Authorization

5.1 Subscription Recurring Billing

By subscribing to a paid plan, you expressly authorize Callirra to charge your payment method on a recurring basis for the applicable subscription fee until you cancel per Section 6. Subscriptions renew automatically at the end of each billing period unless canceled. We will send advance notice before the renewal of any annual subscription.

5.2 Credit Purchase Authorization

Each credit pack purchase is a one-time transaction authorized at checkout. The amount displayed at checkout is the amount charged.

5.3 Payment Processor

Payment card data is processed exclusively by our Merchant of Record and PCI-DSS certified payment processor, Waffo Pancake. We do not store full card numbers on our servers. Waffo Pancake also handles tax compliance, invoicing, and order-related customer support on our behalf.

6. Cancellation Policy

You may cancel your subscription at any time through:

  • Account Settings → Subscription → Cancel Subscription (recommended, in-product)
  • Email: support@callirra.com from your registered email address

Cancellation stops future charges. Your subscription remains active until the end of the current billing period. Credits purchased separately are not canceled and remain subject to their validity period.

7. Refund Policy

Due to the immediate and intangible nature of our digital services, refunds are generally limited to unused credits as described in our Refund Policy.

  • Unused credits are refundable within 7 days of purchase when requested through the refund flow or support@callirra.com.
  • Consumed credits and completed or partially completed AI tasks are non-refundable.
  • Unused plan quota is refundable within 7 days of any subscription charge, including renewals.
  • Refunds requested through Waffo Pancake are processed according to the applicable Waffo refund policy and returned to the original payment method.

8. Acceptable Use Policy

Your use of the Service is governed by our Acceptable Use Policy. In particular, you agree not to use the Service to generate prohibited content, including NSFW material, violence, hate speech, child-unsafe content, deepfakes or impersonation, or content infringing copyright or trademarks.

9. AI Output and Intellectual Property

Subject to these Terms, AI-generated content produced in response to your inputs (“Outputs”) is owned by you. Callirra grants a limited, non-exclusive permission for your commercial use of Outputs generated while you have an active paid subscription, where the applicable model and provider rules permit commercial use and subject to those rules, the law, and the rights in your Inputs. Outputs generated on the Free plan or with credit-pack-only funds while no paid subscription is active are for personal, non-commercial use. Commercial permission for eligible Outputs generated during an active subscription continues after cancellation or expiry; subscribing later does not retroactively grant commercial permission for earlier Free-plan or credit-pack-only Outputs. AI-generated Outputs are marked as AI-generated in your asset library and generation history.

By submitting content to the Service (“Inputs”), you grant Callirra a limited, non-exclusive license to process your Inputs solely to deliver the Service. We do not use your Inputs to train AI models without your explicit consent.

Our Service uses third-party AI model providers. Outputs may be influenced by these providers' models. We do not guarantee specific output quality and accept no liability for outputs generated by third-party models.

10. Data, Privacy, and Security

Your use of the Service is governed by our Privacy Policy. Payment card data is processed exclusively by our PCI-DSS certified payment processor Waffo Pancake and is not stored on our servers. Account data is retained as described in the Privacy Policy.

11. Disclaimers and Limitation of Liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR ACCURACY OF AI OUTPUTS.

AI-generated content may contain errors or inaccuracies. You are solely responsible for reviewing and verifying Outputs before relying on them. Do not rely on AI-generated content for legal, medical, financial, or other professional advice without qualified professional review.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CALLIRRA SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES. OUR TOTAL LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

12. Termination

We may suspend or terminate your account if you materially breach these Terms, we suspect fraudulent activity, or as required by law. If we terminate for reasons other than your breach, we will provide a pro-rated refund for any unused prepaid period. You may delete your account at any time by contacting support@callirra.com.

13. Governing Law and Dispute Resolution

These Terms are governed by the laws of the People's Republic of China, without regard to conflict of law provisions. Before initiating any formal proceedings, please contact support@callirra.com to attempt informal resolution.

14. Changes to These Terms

We may update these Terms at any time. Material changes will be notified by email or in-product notice at least 14 days before the effective date. Continued use constitutes acceptance.
