Privacy Policy | Knight Kitten

Operator and contact

Knight Kitten (https://knightkitten.org) is operated by Li Kai, based in China. For privacy questions and requests, contact support@knightkitten.org. You do not need to sign in to email us.

Data we use

We process account details (including your name, email and profile image), authentication and session records, prompts, selected generation settings, task status and result links to provide and maintain the service. If purchasing is available, we also process order, payment-status and credit records; payment providers process payment credentials. Do not send us full card numbers, security codes or passwords.

Prompts and selected styles may be stored in your browser so you can resume a draft. Clear this site's browser data to remove local drafts. Uploaded image bytes are not stored in browser drafts or our task records. Avoid submitting unnecessary sensitive personal data and obtain permission before uploading another person's information.

Providers and international processing

Cloudflare provides hosting and database infrastructure. Video generation sends the prompt, generation instructions and reference image to an external AI processing provider using Seedance. Result videos may be hosted by that provider and their URLs may expire. Download results you wish to keep promptly.

Waffo prompt screening is an additional safeguard that is enabled when merchant credentials are configured. While merchant onboarding is pending and credentials are absent, this additional screening is not active. When enabled, prompts are submitted to Waffo before generation and only an allowed prompt proceeds to the video provider. Waffo states that this screening service does not retain the original prompt after responding. This text screening does not inspect uploaded images or guarantee safety of generated outputs. Provider processing and retention policies apply separately.

When you use a configured social login, email or payment service, the relevant provider receives the information necessary for that service. Providers may process data outside your country, including outside China. We use service providers for operating the service and do not sell personal data. We may disclose necessary records to comply with legal obligations or investigate abuse.

Cookies and browser services

We use authentication cookies, language preferences and local draft storage. Some fonts are loaded from Google Fonts, which receives the network request. Provider-hosted videos also contact their hosts when played. You can clear browser storage or block cookies, but sign-in and saved preferences may stop working.

Access, correction, deletion and account closure

• Access: view your profile, video history, orders and credit records in your account. For a copy of other personal data we hold about you, email support or submit an account support ticket with the subject “Privacy — access”.
• Correction: update your name and avatar in Profile. For email changes or other corrections, contact support and identify the information to correct.
• Deletion: email support or submit a ticket with the subject “Privacy — deletion”, describing the data or task IDs concerned. Requests can include prompts and task records. Local browser drafts must also be cleared on your device. We will request provider deletion where applicable, but cannot remove copies downloaded or shared outside our control.
• Account closure: email support with the subject “Privacy — close account” from the registered email, or submit a signed-in ticket. Account closure is handled by support; there is no self-service deletion button. We verify ownership, explain retained records and outstanding orders or disputes, revoke account access and remove or anonymize data no longer needed. Closing an account is not an automatic refund request.

We acknowledge privacy requests within 3 business days and process verified requests within 30 calendar days after identity verification, subject to applicable law. We request only information reasonably necessary to verify ownership. If additional time is legally permitted and necessary, we explain the reason and expected completion date before the deadline. If we cannot fulfill part of a request, we explain the legal or operational reason and the available review process. Reply to the same ticket or email to challenge a decision. Applicable rights to restrict or object to processing, withdraw consent, request data portability or complain to a competent authority remain unaffected.

Retention

Account data is retained while the account remains open. After closure, data no longer needed is deleted or anonymized within 30 days. Generation task records are retained for no more than 90 days; necessary billing or dispute evidence is kept separately when required. Orders and financial records are retained for the periods required by applicable tax, accounting and other laws. We retain only the information needed for those obligations, unresolved disputes or lawful preservation requests and remove it when those reasons end.

Provider-hosted files follow the provider's retention rules and may expire sooner than our task records. Our retention periods do not guarantee continued availability of those files. Business days mean Monday through Friday, excluding public holidays in China.
