Privacy Policy

Last updated: 29 October 2026

Coloruna is a coloring app for iPhone, iPad and Android. This policy explains what data we collect, why we collect it, who helps us process it, how long we keep it, and how you can control it. We do not sell your data.

1. Who we are

Coloruna is made by SEVENTYTHREE LINES DEVELOPMENT PRIVATE LIMITED ("73Lines", "we", "us"), 808, The Capital 2, Science City Road, Sola, Ahmedabad, Gujarat 380060, India. We are responsible for the personal data described in this policy. You can reach us at privacy@mail.coloruna.73lines.com.

2. What we collect

Your account

When you create an account we keep your email address and your name. If you sign in with Google or Apple, we keep the identifier they give us for your account; for Apple we also keep a token that lets us end that sign-in with Apple when you delete your account. If you set a password, we store it only in hashed form. Anything you add to your profile, such as a photo, a short bio and your preferences, is kept with your account.

Your artwork

Your colorings and drawings are saved on your device. When you are signed in, they are also saved to your account on our servers so you can open them on your other devices. We never sell your artwork and never share it unless you export or share it yourself.

Photos and words for AI pages

When you turn a photo into a coloring page, the photo is uploaded to our servers. When you describe a page in words, the words are sent to our servers. Section 4 explains what happens to them.

Your device and app use

Purchases

If you subscribe to Coloruna Pro, Apple or Google handles the payment. We never see your card details. We receive whether your subscription is active and your purchase history, so we can give you Pro.

We do not build profiles to sell, and we do not sell your personal data.

4. AI pages: your photos and words

Coloruna shows ads from Google AdMob. To show and measure ads, Google may collect your device advertising identifier, your IP address and how you interact with ads. Where the law requires it, we ask for your consent first, and you can change your choice at any time under Profile > Ad privacy choices. On iPhone and iPad, ads are only personalized if you allow tracking. When you watch an ad to get an extra page, Google tells our servers your account id so we can add the page.

Our servers and database are in a DigitalOcean data center in Bangalore, India. The services in section 5 may process data in other countries. Data travels to and from our servers over encrypted connections (HTTPS).
