Privacy Policy

Privacy Policy

This policy explains what data Coloring Book Maker (the “app”), made by Charles-Adrien Fournier (“we”, “us”), handles and why. We collect as little as possible: there is no account, no advertising and no tracking.


Photos and ideas you turn into coloring pages

When you create a coloring page, the photo you choose (or the idea you type) is sent over an encrypted connection to our server, hosted on Google Firebase, which forwards it to Google’s Gemini AI service to draw the coloring page. The finished page is sent back to your device.

  • We do not store your photos or ideas on our servers. They are used only to create the page you asked for.
  • We use Google’s paid Gemini API, under terms that do not allow Google to use your photos to train its models. Google may keep requests for a limited time to detect abuse, as described in the Gemini API terms.
  • The app asks for your permission before the first photo or idea is sent.
  • Only send photos you have the right to use. Please be thoughtful with photos of other people, especially children.

The coloring pages you create are saved only on your device, in the app. Deleting a page or the app removes them.


Subscriptions

Purchases are handled by Apple. We use RevenueCat to know whether your Coloring Pass is active. RevenueCat receives an anonymous identifier generated by the app and your purchase history, never your name or Apple Account details. Our server uses this anonymous identifier to check your subscription and count the pages you create each day; it keeps only that count and the date.


Coloring page library

The printable library is downloaded from Google Firebase Storage. Your favorites and your daily free download are stored only on your device.


Photos access

The app saves coloring pages to your photo library only when you ask, with add-only access. It uses the system photo picker, so it sees only the photos you choose. The camera is used only when you take a photo to turn into a coloring page.


Children

The app is meant to be used by parents, teachers and adults, who choose the photos and make purchases. We do not knowingly collect personal information from children.


Your choices

You can delete your coloring pages at any time in the app. To stop all processing, delete the app. For any question or request about your data, contact us at feedback@cafournier.com.


Changes

We may update this policy when the app changes. The date at the top shows the latest version.
