Your privacy is important to us. This Privacy Policy explains how Zend collects, uses, and protects your information when you use our mobile application and services.

Information We Collect

Information You Provide

We collect information that you provide directly to us, such as:

Account information (display name, email if provided)
Recovery goals and preferences
Content you create (posts, check-ins, reflections)
Support requests and communications

Information Collected Automatically

When you use Zend, we automatically collect certain information:

User ID: Unique identifier for your account (Firebase Authentication)
Product Interaction: App usage data, feature interactions, and engagement metrics (Firebase Analytics)
Purchase History: Subscription status and purchase information (RevenueCat)
Usage Data: Screen Time API data for app blocking functionality
Diagnostic Data: Crash reports and performance metrics (Firebase Crashlytics)

Screen Time API Usage

Zend uses Apple's Family Controls API (Screen Time) to help you block distracting apps during focus sessions. This allows us to:

Set up Screen Time schedules that prevent access to selected apps during your designated focus hours
Monitor when focus sessions are active
Track which apps you've selected to block

This data is stored locally on your device and is not transmitted to our servers. We only access the apps you explicitly select for blocking through the iOS Family Activity Picker.

Third-Party Services and SDKs

We use the following third-party services that may collect information:

Firebase Services (Google)

Firebase Authentication: User account management and authentication
Firebase Analytics: App usage analytics and user behavior insights
Cloud Firestore: Database for storing your app data (goals, streaks, posts, etc.)
Firebase Crashlytics: Crash reporting and app stability monitoring

Firebase's privacy policy: https://policies.google.com/privacy

RevenueCat

We use RevenueCat to manage subscriptions and process payments. RevenueCat collects purchase history and subscription status to provide subscription management services.

Facebook SDK

We use Facebook SDK for app analytics and advertising attribution. This helps us understand how users discover our app and measure the effectiveness of our marketing efforts.
