1. Introduction

Welcome to WallCool ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we handle your information when you use our mobile application (the "App").

This App is designed for users globally (excluding Mainland China). By using the App, you consent to the practices described in this policy.

2. Data We Do Not Collect

To ensure your privacy:

• Account Registration & Authentication: To provide cloud syncing for your favorite wallpapers and manage your Pro access, our App offers secure authentication via third-party services (such as Apple Sign-In). When you choose to log in, we collect basic profile information strictly necessary for account creation and customer support, including your name, email address, and a unique user ID. We do not collect or store any passwords.
• No Face Data: We do not collect, process, or store any facial recognition data.
• Location Data: We do not track or collect your precise GPS location. However, our third-party advertising partners (e.g., Google AdMob) may collect your coarse location data (such as city or region level) to serve you geographically relevant advertisements.

3. Data We Collect and How We Use It

We collect minimal data necessary to provide the App's services:

A. Permissions

• Photo Library Access: We request access to your device's Photo Library strictly for the purpose of saving the wallpapers you choose to download. We do not read, upload, or analyze your personal photos stored in your library.

B. Usage and Device Data (Technical Data)

• We may collect non-personal technical data such as your device model, iOS version, language settings, and crash reports. This helps us fix bugs and improve App stability.

C. Transaction Data (In-App Purchases)

• We offer subscriptions (Monthly/Yearly) and one-time purchases (Lifetime) via Apple's In-App Purchase system.
• Payment Information: All financial transactions are processed directly by Apple (App Store). We do not collect or store your credit card or banking information.
• Purchase History: We use a third-party service, RevenueCat, to validate your subscription status (e.g., checking if you are a Pro member). RevenueCat generates an anonymous App User ID to manage your receipt status without knowing your real identity.
