Privacy policy
This policy explains what ColorBlend.app does with information when you use the site. It was last updated on October 5, 2026. If you have a question, email support@colorblend.app.
The short version
Color mixing happens in your browser. We do not ask you to create an account, and we do not keep a library of your palettes on a server. If you email us, we use that email to reply.
Information you give us
The only information you deliberately send us is what you put in an email to support@colorblend.app. That includes your email address, anything in the message, and any attachment you choose to add. We use it to answer you and to keep a record of the request. Please do not send passwords, payment card numbers, or government ID numbers. We have no account system that would need them.
Information collected when you browse
The pages are static files. Dragging the color bubbles, checking contrast, and copying code do not send your palette to us. A copy action stays on your device.
The host that delivers the site keeps ordinary connection logs. A log line typically includes the page address, the time, your IP address, and the browser you used. We use those logs to keep the site available, to fix errors, and to block abuse. We do not sell them.
Some links include the two colors you are opening in the sandbox, as part of the web address. That is how the sandbox knows which pair to show. The colors are not stored in an account. Like any other page request, the address can appear in a server log.
Fonts
The typefaces are files on this site. Your browser loads them from ColorBlend.app with the pages. A visit does not send a separate request to Google Fonts.
Cookies
ColorBlend.app does not use a login cookie, because there is no login. We do not use advertising cookies. We do not sell personal information.
How long we keep information
Connection logs are kept for as long as the host normally retains them, then deleted or rotated. Email we receive is kept long enough to answer you and to refer back if you write again about the same issue. You can ask us to delete an email conversation, and we will do so unless we need to keep it for a legal reason.
Children
ColorBlend.app is a tool for people building interfaces. It is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has emailed us, write to support@colorblend.app and we will delete the message.
Changes
If this policy changes, we will update the date at the top of this page. Continued use of the site after that date means the new policy applies to new visits.
