Privacy Policy

Last updated: October 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 and how the app is used, Coloruna sends a small number of anonymous events to its own server. We use them only to improve the picture library and the app. We do not sell or share them, and there are no third-party analytics tools.

What is recorded

• A random identifier created on your device (it is not derived from you or your device) and a random id for each visit.
• Picture activity: which picture was opened, started, resumed, left or completed, how far along you were, and how long you coloured.
• How long a visit was active.
• Once per visit, coarse context: your approximate country (worked out by our network provider, Cloudflare, from your connection; Coloruna never reads or stores your IP address), your operating system, browser type and device type (phone, tablet or computer), how the app was opened (website, installed web app or mobile app), your language, a screen-size class (phone, tablet, laptop or desktop; not the exact size), the website that linked to us (host name only) and the utm_source tag of the link, if it had one.

What is not recorded: your IP address, name, e-mail address, precise location, advertising or device identifiers, contacts, or the full addresses of pages you visited.

Opting out. If your browser sends Do Not Track or Global Privacy Control, Coloruna sends no analytics at all. Clearing the site's data in your browser (or deleting the app) discards the random identifier; the next visit then counts as a new anonymous visitor.

How long we keep it. Individual events and the summary kept for each random identifier (first and last visit, number of visits, the coarse context above) are deleted after about 13 months.

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. It stores the random identifier and your progress in your browser's local storage. A single session cookie is used only by administrators who sign in to the management panel.

Children

Coloruna is intended for people aged 13 and over and is not directed at children under 13. The pictures themselves are suitable for all ages, but we do not knowingly collect data from children under 13 (or the age required by your local law). If you believe a child has used the app, you can clear its data by uninstalling it or clearing the browser data for this site.

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.
