Terms of Service
The terms for using Black to Colour to colorize a still photograph
The service
Black to Colour (黑白转彩色), at blacktocolor.com, colorizes one still photograph at a time. You upload a black-and-white or faded photo, add optional color notes, and receive a color version of that frame.
These terms cover the website, accounts, credits, and the colorize tool. Using the service means you accept them.
Accounts
Colorizing a photo requires an account and a verified email address. You can register with email and a password, or sign in with Google.
You provide a name and email that we can use to reach you. You keep the password to yourself and the activity on the account is yours, including photos uploaded and credits spent while someone else is signed in on your device.
Photos you upload
Upload a photo you have the right to colorize. That includes a photograph you took, one you were given to restore, or one you otherwise have permission to process.
Do not upload someone else's private pictures. Do not upload a photograph of a minor unless you are allowed to process that photograph. Do not upload a file that breaks the law, or a file whose only purpose is to attack the service.
The color notes you add are part of that job. They describe color. They are not a place to put someone else's personal data.
What the color result is
The result is a color estimate for the photograph you sent. Skin, cloth, sky, and metal are guided by the picture. Exact historical pigments are not guaranteed when the original colors were never recorded.
The frame is meant to stay. If a result moves a face, replaces the scene, or looks unlike the photograph, that job missed. Review the full frame before you share it.
Credits
One accepted colorize job uses 1 credit. If the job fails, that credit is returned.
A new account receives the welcome credits shown at signup. Extra credits, when the pricing page offers them, are added after the checkout on that page succeeds. The price you confirm at checkout is the price for that purchase. Credits already used on a finished colorize are not refunded as cash.
Your photographs
You keep the rights you already have in the photograph and in the color result.
You give Black to Colour permission to use the upload and the color notes for that job only: to send them for colorizing, to return the result to you, and to store the finished image in your Files until you delete it. We do not take ownership of the photograph, and we do not use your uploads to train our own model.
The colorizing step is performed by Alibaba Cloud Model Studio. Sending a photo for colorizing also means that provider receives the image and the color notes for that request, under its own terms.
Acceptable use and content standards
Colorize is a content-generation feature. These standards apply to every photograph you upload, every color note you submit, and every color result the service returns or stores.
You may colorize a still photograph you have the right to process. You may not upload, request, generate, store, or share any of the following six categories:
- Pornography / NSFW. Sexually explicit or pornographic images, nudity presented as sexual content, and color notes that ask for that content.
- Violence / gore. Graphic violence, gore, mutilation, or color notes that ask for it.
- Hate speech. Content that attacks or dehumanizes a person or group because of race, ethnicity, nationality, religion, gender, sexual orientation, disability, or similar status.
- Child-unsafe content (CSAM). Any sexual or exploitative content involving a minor, including a colorized image and a color note that sexualizes a minor. This category has no exception.
- Deepfakes / impersonation. Using the service to pass a person off as someone else, including a face swap, nudification, an intimate-scene composite, or a fabricated act or statement by a real person. Consent does not allow this category. Colorizing a photograph you have the right to restore is not, by itself, this category.
- Copyright / trademark infringement. A photograph, mark, or result you have no right to use, including a trademark used to imply a brand made or endorsed the image.
A color note that asks for a prohibited category is a violation even when the model returns no image. Do not try to get into another account, probe or disrupt the service, or resell access as your own product.
Enforcement
After a confirmed violation we use one or more of these measures: a warning, deletion of the content, a freeze of the account, and clearing the credit balance to zero. Credits cleared for a violation are not refunded.
Child sexual abuse material is removed, the account is frozen, the credit balance is cleared, and we report it to the appropriate authority.
Reports
Report a color result, an upload, or a color note that falls into a prohibited category. Also report a result that impersonates you or infringes a right you hold.
Send the report to support@blacktocolor.com with the subject "Content report", or use the contact form on the home page. Include where the image can be found, which category it falls under, and an email where we can reply. Do not attach a copy of child sexual abuse material. Describe it and identify the account or file instead.
We do not disclose the reporter to the reported account. Each report is reviewed on what it describes. A report made to harass someone, or a report the sender knows is false, can itself lead to a warning, content deletion, an account freeze, or a cleared credit balance.
How quickly we respond
| Level | What it covers | First response | Decision |
|---|---|---|---|
| L1 — Critical | Child-unsafe content (CSAM) | Within 2 hours | Within 24 hours |
| L2 — High | Pornography / NSFW, violence / gore, hate speech, deepfakes / impersonation, or clear copyright / trademark infringement | Within 24 hours | Within 3 business days |
| L3 — Medium | Another violation of these content standards | Within 3 business days | Within 7 business days |
| L4 — Low | A first, limited mistake that is fixed by removing one image | Within 5 business days | Within 15 business days |
If a review needs longer than the decision time, we email the reporter with the reason before that time runs out.
How we review a report
A report is handled in this order:
- Receive. The report arrives at support@blacktocolor.com or through the contact form. We confirm receipt to the address the reporter gave.
- Classify. We assign L1, L2, L3, or L4 from the table above.
- Check. We look at the stored color result, the color notes for that job when they are still available, and the account that created it. The colorize provider may also refuse a request under its own rules. That refusal does not replace this review.
- Decide. We choose the enforcement measure: a warning, deletion of the content, a freeze of the account, clearing the credit balance to zero, or, for child sexual abuse material, a report to the appropriate authority.
- Tell the reporter. When the reporter left an email address, we send the outcome. We do not send them a copy of the prohibited image.
You can ask for a second look within 10 business days of the decision by emailing support@blacktocolor.com with the subject "Content appeal". Someone who did not make the original decision reviews the appeal, and we reply within 10 business days.
Closing an account
You can delete your account from the account security settings. You can delete a single result from Files. Deleting a file removes that stored image.
We can suspend or close an account that breaks these terms, including an account used to upload photographs the person has no right to process. Credits left on a closed account are not paid out.
Availability
The site and the colorize model can be unavailable, slow, or wrong. A failed job returns the credit. A finished image that you dislike is still a completed job.
Liability
The service is provided as it runs. We do not promise that a result matches the colors of the day the photograph was taken, or that the service will be available at every moment. To the extent the law allows, we are not liable for indirect or consequential loss from using a result or from being unable to use the service.
Changes
When these terms change, the new version is posted on this page with a new date. Continuing to colorize after that date means you accept the updated terms.
