Website privacy

For kids: this website does not ask who you are and does not remember you. Color away.

What this website collects

Nothing. gullu.app has no cookies, no analytics or tracking scripts, no ads, no accounts, no sign-up forms and no comment boxes. Every font, picture and script comes from gullu.app itself; nothing loads from other companies.

Coloring online

The sample pages you can color on gullu.app run entirely in your browser. Your coloring is never uploaded. If you tap “Save my picture”, the file goes straight to your own device.

Our hosting provider

The site is delivered by Cloudflare, which processes visitors’ IP addresses to deliver the pages and protect the site from attacks. We do not use that information to identify anyone.

Email

Joining the Android early-access Google Group (for grown-up testers) shares that person’s email address with SyntyAxis, the group’s owner; we use it only to run the test.

If you write to [email protected], we use your email only to reply. If a child writes to us, we answer once and then delete the message.

The Gullu app

The app has its own privacy policy: Gullu app privacy policy. On iPhone, iPad and Mac the App Privacy label is “Data Not Collected”. The Android version, coming soon, shows child-directed ads from Google AdMob; its policy explains what that ad service processes.
