How Seedance3 collects, uses, and protects personal information

1. Introduction and Data Controller

Tang Yi ("Seedance3," "we," "us," or "our") operates Seedance3, an AI image and video generation service available at https://seedance3.lol (the "Service"). This Privacy Policy explains how we collect, use, retain, disclose, and protect personal information when you use the Service, and the rights available to you.

Tang Yi is an individual / sole trader operating under the laws of the Hong Kong Special Administrative Region of the People's Republic of China. You can contact us about privacy matters at support@seedance3.lol. We have not appointed a data protection officer.

2. Personal Information We Collect

We may collect:

  • Account information, including your name, email address, profile image if provided, and authentication credentials. Passwords are handled using authentication security controls and are not stored as plain text.
  • Authentication information from Google when you choose Google sign-in, such as the profile information Google authorises us to receive.
  • Payment and credit information, including transaction identifiers, amounts, payment status, subscription status, invoice and credit-transaction records. We do not receive or store full payment-card details.
  • Communications, including messages, requests, feedback, and other information you send to support.
  • Creative inputs and outputs, including prompts, reference images, generated images and videos, generation settings, task status, and related creation history.

5. How We Share Personal Information

We do not sell your personal information, including as that term may be defined under applicable privacy laws. We disclose personal information only as necessary for the purposes described in this policy:

  • Payment processing: Waffo Pancake processes hosted checkout and payment-card information. We receive transaction and subscription information needed to provide the Service; we do not store full payment-card details on our servers.
  • Authentication: Google may provide authorised profile information when you choose Google sign-in.
  • Email delivery: Resend delivers transactional emails such as account verification and password-reset messages.
  • Storage and hosting: We use S3-compatible object storage, including Cloudflare R2 in the current media-archive deployment, to store user-uploaded reference media and generated results.
  • AI processing: When you select a model, we send the inputs necessary to process that request to the applicable third-party AI provider, which may include OpenAI, Gemini, Seedance, or another provider supporting the selected model.
  • Analytics: Google Analytics and Microsoft Clarity receive relevant technical and usage information as described above.
  • Legal, safety, and business transfers: We may disclose information where required by law, to protect rights and safety, or in connection with a merger, acquisition, financing, or sale of assets, with appropriate notice where required.

Service providers may process information only under their applicable terms, confidentiality commitments, and data-protection obligations.

6. International Data Transfers

Our service providers may process personal information in countries or regions other than where you live, including in connection with payment, AI processing, analytics, cloud storage, and email delivery. Where required, we use appropriate safeguards for cross-border transfers, such as contractual data-protection commitments, Standard Contractual Clauses or equivalent mechanisms, and transfers to recipients subject to an adequate level of protection.

7. Security

We use reasonable administrative, technical, and organisational safeguards designed to protect personal information, including HTTPS/TLS in transit, authentication controls, access restrictions, credential security measures, and logging for reliability and abuse prevention.

No system is completely secure. You are responsible for keeping your account credentials confidential. If a security incident affects your personal information, we will investigate and provide notices to affected individuals and regulators as required by applicable law.

8. Data Retention

We retain personal information only for as long as necessary for the purposes described in this policy, unless a longer period is required or permitted by law.

You may also request portability of information you provided to us in a machine-readable form, and withdraw consent where processing is based on consent.

To make a request, email support@seedance3.lol from your registered email address and describe the request. We may need to verify your identity before acting. We aim to respond within 30 calendar days; where the law requires a shorter period, we will comply with that requirement. You may also have the right to complain to the data-protection authority in your place of residence or where you believe your rights were infringed.

10. Children

The Service is intended only for people aged 18 or older. We do not knowingly collect personal information from anyone under 18. If you believe that a child has provided personal information to us, contact support@seedance3.lol and we will take appropriate steps to delete it.

The Service may link to third-party websites or use third-party services. Their privacy practices are governed by their own policies, not this policy. Review those policies before using third-party services.

12. Changes to This Policy

We may update this Privacy Policy from time to time. For material changes, we will provide notice through the Service, by email, or by another reasonable method at least 14 days before the change takes effect where required or reasonably practicable.
