Privacy Policy
Last updated: 2026-07-04
Trazia is operated by ZHAO, XU (赵旭), an individual based in China (the data controller). This policy explains what data we ("Trazia", "we") collect when you use our coloring-page service, and why. Questions: nolan.dev@hotmail.com.
What we collect
Prompts you type to generate a coloring page are sent to our AI providers to create the image.
Photos you upload for the photo-to-coloring tool are processed entirely in your browser and are never uploaded to our servers.
Your email address when you start a subscription checkout.
Your IP address, used only to rate-limit generations and prevent abuse.
Payments
Subscriptions are processed by Waffo Pancake, our payment provider. We never see or store your card details.
Third-party processors
Cloudflare — hosting and AI image generation (Workers AI).
Our image-rendering API provider — for the AI art-render feature.
Waffo Pancake — subscription payments and billing.
International data transfers
We are based in China, and our providers (such as Cloudflare) may process data on servers in other countries, including outside the EU. We share only the minimum needed to run the service and rely on our providers' safeguards.
Cookies & local storage
We use minimal local storage for your language preference and free-usage limits. We do not run advertising trackers without your consent.
Browser extension
The Trazia browser extension turns an image you choose into a coloring page. It works on the single image you right-click, or on the region you drag-select from a screenshot of the current tab when you click its toolbar icon.
That image or cropped region is processed in your browser and handed to the Trazia coloring tool. The extension does not store your images, screenshots, or browsing activity, and does not send them to us or any third party. It acts only after you invoke it, and does not read other page content or your browsing history.
Retention
We keep subscription and email data while your subscription is active. Rate-limit data expires automatically within days.
Your rights (GDPR)
You can request access to, correction of, or deletion of your data at any time by emailing nolan.dev@hotmail.com.
Children
Trazia is made for families. We do not knowingly collect personal data from children.
Changes
We may update this policy. The current version is dated 2026-07-04.
