Privacy Policy
Last updated: November 2026
Overview
colorbynumber.art is a free, client-side tool. All image processing happens in your browser — your photos are never uploaded to our servers. This policy explains what limited data we collect and how it is used.
Data We Collect
We do not ask for or store personal information such as your name or email address. Two third-party services may collect usage data, and both are switched off until you accept cookies:
- Google Analytics — collects anonymous, aggregated page-view data so we can see which pages and features are used. If you rate a generated sheet, we also send your rating, optional reason, and generation settings through our analytics setup. Your photo and filename are never included in feedback.
- Google AdSense — serves the advertisements that fund the site.
Advertising Cookies
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or to other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
Cookies and Your Choice
On your first visit we ask whether you accept cookies for advertising and analytics. If you decline, neither Google Analytics nor Google AdSense is loaded and no advertising or analytics cookies are set. If you accept, both may place cookies on your device. Your choice itself is remembered in your browser's local storage (not a cookie) so we do not ask again.
We also remember in local storage when you answer or dismiss the optional sheet feedback prompt, so it is not shown again in that browser.
You can change or withdraw your choice at any time using the link in the footer of every page, which shows the banner again.
Your Images
Images you upload are processed entirely in your browser using JavaScript. They are never sent to our servers or stored anywhere outside your device.
Third-Party Links
This site may display ads containing links to third-party websites. We are not responsible for the privacy practices of those sites.
