Privacy Policy

Last updated: September 2026

Coloruna is a paint-by-number coloring game available as a website and as iOS and Android apps. We designed it to work without accounts and to collect as little data as possible.

No account, no personal data

You do not need to register or sign in. We do not ask for your name, e-mail address, or any other personal information.

What stays on your device

Your coloring progress, favorites, settings, points and achievements are stored only on your device (in your browser's local storage or inside the app). They are not uploaded to our servers. Clearing your browser data or deleting the app removes them.

Anonymous usage statistics

To understand which pictures people enjoy, the app sends a small number of anonymous events to the server (for example: the app was opened, a picture was started, a picture was completed and how long it took). These events carry a random identifier generated on your device — not your name, e-mail, precise location or device identifiers — plus a coarse platform label (iOS, Android, web). We use them only to improve the picture library. We do not sell or share this data.

No advertising or third-party tracking

Coloruna contains no advertising networks, no social-media pixels and no third-party analytics SDKs.

Cookies

The public game does not set cookies. A single session cookie is used only by administrators who sign in to the management panel.

Children

Coloruna is suitable for children. Because we collect no personal information, nothing is knowingly collected from children under 13 (or the age required by your local law).

Sharing pictures

When you use the Share or Save buttons, the finished picture is handed to your device's sharing system or downloads folder; we do not receive a copy.

Changes

If this policy changes, the new version will be published at this address with an updated date.
