Privacy Policy
Updated November 3, 2026
BULIN 47 AI is operated by 黄墨 as an individual. For questions about the service, refunds, or privacy, contact [email protected].
The operator named above is responsible for the personal information described in this policy. What we receive depends on whether you browse the public site, sign in or choose to upload.
Visiting and signing in
Cloudflare serves the public website and processes connection details such as your IP address and the pages requested to deliver and protect it. Watching the public sample does not require your photo. If you choose Google sign-in, Google handles authentication and we use your Google account identifier, email address and sign-in status to create or recognize your account. We may also receive your profile name or photo. We do not receive your Google password.
Uploading and previewing a photo
Uploading sends the photo to the service so you can preview and select it. On the hosted site, Cloudflare processes the image and stores a sanitized copy in private R2 storage. D1 holds account, session and upload records such as the file reference, owner, dimensions and expiry. We record the photo declaration you submit. You must be 18 or older and the only person shown.
When the selected photo goes to the video provider
If generation is enabled, confirming a job sends the selected photo and generation instructions to MiniMax through its China-region API. They are needed to render your appearance in the generated performance. We keep the job ID, status and delivery details to return the video to your account and handle failures. A private preview alone does not send the photo to the video model. We seek separate permission before using your photo or result as a public sample.
Providers and processing locations
Cloudflare provides hosting and private storage for the public site. Google processes the sign-in if you choose it and handles messages sent to our Gmail support address. Depending on which features you use, information may be processed outside your country. A provider's region for one operation does not establish where every copy is kept. We have not verified a retention period or model-training exclusion for MiniMax under our current account. Ask us before submitting a photo if either affects your decision.
Photo and video retention
A signed-in photo upload normally expires after 24 hours, and you can delete it sooner using the upload controls. An active or unresolved job may still need its input. Finished videos are normally available to download for seven days. Check the expiry shown for the item you want to keep. Losing access, deleting a source photo and deleting a finished video are separate events. Storage cleanup and deletion of copies held by a provider may take place later.
Order records and support
If your account offers a PayPal checkout and you choose to use it, PayPal processes the payment details. We will use the order reference, amount, payment or refund status, and linked job ID to fulfil the order and resolve disputes. When you contact support, we receive your email address, message and any attachments you choose to send. We keep account, security, support and transaction records as needed for the account, the case and applicable recordkeeping obligations. A photo's 24-hour expiry does not apply to those records.
Cookies and access controls
The site uses necessary cookies and browser storage to keep you signed in, protect requests, remember your language or preserve progress in the creation form. Blocking them may interrupt sign-in or clear a draft. Private media is subject to account and ownership checks. The operator and providers may process it as needed for the features described here or to investigate a problem.
Your choices and requests
You can ask for access, a copy, a correction or deletion of your personal information, or withdraw permission for future consent-based use. Email [email protected] from your account email if possible, and include a job or order ID if relevant. We may ask for the minimum information needed to find the record and verify the request. Do not send passwords, one-time codes or full card details. Withdrawing permission does not undo a completed generation. If we must retain a record or cannot complete part of a request, we will explain why. You may also complain to the competent privacy authority.
Changes to this notice
We will update this notice when enabled features, recipients or the way we use your information materially change. We will give notice before applying a new use and ask for fresh permission when required.
Age and use of your own photo
You must be at least 18 and have the right to use a photo showing only yourself. For each new photo, confirm this and agree to create an AI singing video featuring your likeness. These are your own declarations. The site does not verify your age or identity.
We record the declaration version and confirmation time with the photo. Each generation request refers to that photo so we can establish what use you agreed to. This declaration does not collect your date of birth or identity documents.
