Terms of Service

Colorbook (colorbooklab.com) is operated by US App Studio (usappstudio.com). By using the site you agree to these terms.

The service

The themed coloring-page library is free for personal, family and classroom use. The AI studio (photo → coloring page, text → coloring page, old-photo restoration and living-photo videos) is a paid tool: it runs on one-time page credits or a weekly subscription, sold through our payment partner Paddle, which acts as merchant of record.

Credits

One credit equals one AI image generation; a living-photo video costs 10 credits. Credits are one-time purchases valid for 1 year, tied to your checkout email — sign in with that email on any device to use them. The weekly plan covers up to 10 AI pages per day and renews until cancelled (one click via your Paddle receipt). A failed generation never consumes a credit.

Your content

Photos you upload are processed once to produce your result and are not stored by us. You must own or have rights to any photo you upload, and you may not use the service to create unlawful, infringing or harmful content. Pages you generate are yours to print and use personally; the free library may not be resold or redistributed as-is.

Fair use & availability

Daily fair-use caps apply to keep the service fast for everyone. The service is provided “as is” — AI output quality varies and we don't guarantee uninterrupted availability. Our total liability is limited to the amount you paid in the last 12 months.
