Credits

The service may use a credit-based system for AI video generation, video remaking, and other features.

The number of credits required may vary depending on:

• Generation model
• Video duration
• Video resolution
• Generation mode
• Number of generated results
• Reference video processing
• Selected features
• Other generation parameters

Credits may only be used within Katana AI and have no cash value.

Credits cannot be exchanged for money, transferred, or redeemed outside the service unless explicitly stated otherwise.

Purchased or promotional credits may be subject to expiration periods displayed on the website.

Credits included in subscription plans may expire at the end of the applicable billing cycle and may not roll over unless otherwise stated.

Subscriptions and Fees

Katana AI may offer monthly or recurring subscription plans.

The applicable price, billing cycle, included credits, features, and usage limits are displayed on the pricing page.

Subscriptions automatically renew at the end of each billing period unless canceled before the next renewal date.

By purchasing a subscription, you authorize us and our payment providers to charge the applicable recurring fees.

You may cancel your subscription at any time before your next billing date.

Cancellation prevents future renewal charges but does not automatically create a refund for previous payments.

We may change plan prices, included credits, features, or other subscription conditions in the future.

Where appropriate, material changes will be communicated through the website or other reasonable means.

Payments

Payments are processed through third-party payment providers such as Stripe, PayPal, or other supported processors.

We generally do not directly store full payment card details.

You agree to provide accurate billing information and authorize the applicable payment provider to process your payment.

Payment methods may vary depending on your country, region, account, and payment provider availability.

Refunds

Refunds are governed by our separate Refund Policy.

Please review the Refund Policy before making a purchase.

Unless otherwise required by applicable law, purchasing credits, subscriptions, or other digital services does not automatically entitle you to a refund after the service has been used.

AI Video Generation

The service uses artificial intelligence and third-party technologies to generate and recreate videos.

Generated output may contain:

• Unexpected visual elements
• Inconsistent character appearances
• Changes in product details
• Motion inconsistencies
• Camera movement differences
• Unexpected scene transitions
• Visual artifacts
• Incomplete results
• Results that differ from the reference video or prompt

AI-generated content is probabilistic and cannot be guaranteed to produce the same result each time.

Reference-based video remaking may follow the general shot structure, motion, pacing, or visual style of a reference video, but exact frame-by-frame reproduction is not guaranteed.

You are responsible for reviewing generated videos before publishing, distributing, monetizing, selling, licensing, or otherwise using them.

User Inputs

You may provide content such as:

• Reference videos
• Product photographs
• Character or model images
• Clothing and object references

You represent and warrant that you have all necessary rights, licenses, permissions, consents, and legal authority to submit such content.

You must not upload or submit content that infringes another person's copyright, trademark, privacy rights, publicity rights, contractual rights, or other legal rights.

User Content Ownership

We do not claim ownership of content you provide solely because you submit it to the service.

You retain whatever rights you lawfully hold in your own videos, images, prompts, text, audio, and other original materials.

However, by submitting content to the service, you grant us a limited license to process, transmit, store, reproduce, and use the submitted content as reasonably necessary to provide, maintain, secure, and improve the service.

This license ends when the content is deleted, except where continued retention is reasonably necessary for legal, security, fraud prevention, backup, or technical purposes.

This includes reference videos, personal photographs, product images, brand assets, audio tracks, and other copyrighted or identifiable content.
