About Coloruna

Who makes Coloruna

Coloruna is made by SEVENTYTHREE LINES DEVELOPMENT PRIVATE LIMITED ("73Lines"). We are based at 808, The Capital 2, Science City Road, Sola, Ahmedabad, Gujarat 380060, India. The same company runs this website.

We also make Split Circle, an AI expense manager.

Why we made it

We wanted a coloring app for a quiet few minutes on the phone or tablet you already have. You pick a page, choose your colors and color it in the app, with brushes and paints that feel real, rather than printing it out. When you want a page of your own, you can start from a photo or a few words.

What Coloruna does

• A library of six collections: mandalas, landscapes, portraits, fantasy, anime and abstract art.
• Three ways to color: any colors you like, color by number, and mosaic, where squares are filled by number.
• Brushes such as fineliner, pencil, chalk and crayon, and paints such as marker, watercolor and airbrush.
• AI pages: turn a photo into a coloring page, or describe one in a few words, then color it in the app. For a photo, you choose the outline style and how much detail you want.

Coloruna is coming soon to the App Store and Google Play.

How we approach it

• Your photos stay yours. A photo you turn into a page is used only to make that page. We keep the photo and the page for 90 days so you can open them again, then delete them. We never sell your photos, your artwork or your personal data.
• Safety checks. Every photo and description is checked for unsafe content before a page is made, and requests that fail the checks are refused.
• For ages 13 and up. You must be at least 13 to use Coloruna.
• AI is optional. The library, color by number and mosaic work without it.
• You can leave at any time. Deleting your account in the app takes effect straight away. Account deletion explains what is removed and what is kept.
