Privacy Policy
What Black to Colour collects when you colorize a photograph, and why
Who this covers
This policy describes Black to Colour (黑白转彩色) at blacktocolor.com. It covers the account, the photograph you send for colorizing, the stored result, contact messages, and the newsletter.
Account
When you register or sign in, we store:
- your name
- your email address
- a password hash, if you use email and password
- whether the email is verified
- the session that keeps you signed in
If you sign in with Google, we receive the name, email address, and profile image Google shares for that sign-in. We do not receive your Google password.
A new account is added to the newsletter email list. You can turn that off in account settings, or from the unsubscribe link in a newsletter email.
The photograph
To colorize a photo, the browser sends us the image and any color notes you typed. We pass both to Alibaba Cloud Model Studio (Qwen image editing, Beijing region) so it can produce the color result.
We do not save the original upload in your Files. The finished color image is saved there, privately, under your account, on Cloudflare storage. The temporary link returned by the model expires in about 24 hours. The copy in Files stays until you delete that file.
Color notes are used for that job. They are not published.
Credits and payment
We store the credit balance and the record of each colorize job, including whether the credit was used or returned.
When you buy credits, the checkout provider named on the pricing page processes the payment. We keep the purchase status needed to add credits to the account. We do not store your full card number.
Messages you send us
The contact form collects your name, email address, and message, and emails them to support@blacktocolor.com so we can reply. Use that form for a question about a photo, a bill, or a fault. Do not put a photograph's private contents into the message if you do not want that text in an email inbox.
What we use it for
We use this information to:
- run the account and keep you signed in
- colorize the photograph you submitted and show you the result
- keep credits accurate, including the welcome credits and any credits you buy
- send verification, password reset, and newsletter email
- answer a message you send to support
- protect the service from abuse
Cookies
Sign-in and language use cookies. The details are in the Cookie Policy.
How long it stays
The account and the Files in it remain until you delete them. A colorize record stays with the account so the credit history remains accurate.
The model provider's temporary result link lasts about 24 hours. After we have copied the result into Files, that link is no longer how you access the image.
Deleting
Delete one result from Files to remove that stored image. Delete the account from the security settings to close the account and remove its records. For a copy of what we hold, or to ask about images still in storage after the account is gone, email support@blacktocolor.com.
Other services
These providers process data so the product can run:
- Alibaba Cloud Model Studio receives the photograph and color notes for the colorize job
- Cloudflare hosts the site, stores the finished image, and sends account email
- Google receives the sign-in if you choose Google
- The newsletter provider stores the email address used for the list
- The checkout provider, when you buy credits, receives the payment
Each of those companies handles that data under its own terms.
