JustColor works completely offline. The Android app does not request internet permission, so colouring never depends on a connection and no child's activity can be sent to a server.
Does JustColor really work without internet?
Yes. The colouring pages, crayons, patterns, glitter and saved pictures are all stored locally. Once the app is installed, airplane mode makes no difference to how it works.
This is stronger than an app that merely has an offline mode. JustColor does not request Android's network permission at all. There is no login to refresh, content to download, licence screen inside the app or server that must be reachable before a child can colour.
Useful on a plane—and before one
Open JustColor once before leaving only to check that the store installation has finished. After that, the app itself needs no preparation for a trip: all 40+ pages and all colouring tools are already on the device.
Because there are no ads or web links, a child also cannot tap out into content that stops working when the connection disappears.
- Works in airplane mode

- No account or sign-in
- Progress saves on the device automatically
Offline by design protects privacy
An app cannot upload analytics, advertising identifiers or a child's pictures when it has no network access. JustColor also contains no analytics, tracking, advertising or crash-reporting SDKs.
Colouring progress stays in the app's private storage on that device. Cloud backup and device-to-device transfer are deliberately disabled, so the pictures do not quietly leave the device through a backup. The trade-off is worth knowing: if the app is removed or the device is reset, lost or replaced, those saved pictures cannot be recovered.
Built for small hands, not connectivity
JustColor is designed for children aged 2–8. Controls use pictures rather than text, the buttons are large, and there are no menus or settings for a child to get lost in. It works on Android phones and tablets in portrait or landscape.
