1. Introduction
Enchanted Coloring Tiles ("the App") is an AI-powered coloring app developed by Human NPC Studio ("we", "us", "our"). This Privacy Policy explains how we collect, use, and protect information in relation to the App.
We take your privacy seriously, especially the privacy of children. The App is designed to comply with the Children's Online Privacy Protection Act (COPPA) and the Google Play Families Policy.
2. Information We Collect
Google Sign-In
We use Google Sign-In to authenticate users. When you sign in, we receive and store the following information from your Google account:

- Email address — used for account identification
- Profile photo URL — displayed as your avatar in the app
We do not access your Google contacts, calendar, or any other Google services beyond basic profile information.
Coloring Progress
Your coloring progress is stored locally on your device and synced to our cloud servers so you can continue where you left off.
Generated Images
When you create coloring pages, the text prompts you select (subject, emotion, action, style) are sent to our image generation service. No personal information is included in these prompts.
Purchase Information
In-app purchases are processed entirely by Google Play or the Amazon Appstore. We receive only the order ID, product ID, and purchase token to verify and credit your purchase. We do not collect or store payment details such as credit card numbers.
