Introduction
This Privacy Policy describes how Yume ("we," "our," or "the app") collects, uses, stores, and protects your information when you use our iOS habit tracking application.
Yume is designed with privacy in mind. Your habit data stays on your device and in your personal iCloud account—we don't have access to it.
Key Points:
- Your data is stored locally on your device and synced via your personal iCloud account
- We do not collect, access, or store your habit data on our servers
- We use RevenueCat to process subscriptions securely
- We do not sell, share, or monetize your personal data
Information We Collect
1. Data Stored Locally and in iCloud
Yume stores the following data on your device and in your personal iCloud account:
- Habits: Names, icons, colors, frequency settings, and completion records
- Daily lines: Your personal journal entries (one line a day)
- App preferences: Theme, notification settings, week start day
- Completion history: Dates and times when you marked habits as complete
This data syncs automatically via iCloud if enabled on your device. We do not have access to your iCloud data—it belongs to you and is protected by your Apple ID.
2. Subscription Data (via RevenueCat)
When you subscribe to Yume Premium, we use RevenueCat to manage subscriptions. RevenueCat collects:
- Anonymous user identifier: A random ID to track subscription status
- Purchase history: Which subscription plan you purchased and its status
- Device information: Device type and OS version for compatibility
RevenueCat does not have access to your habit data or personal content within the app.
3. Data We Do NOT Collect
Yume explicitly does not collect:
- Your name, email, or contact information
- Your location data
- Your browsing history
- Analytics or usage tracking data
- Advertising identifiers
- Any data from other apps on your device
How We Use Your Data
We use the limited data we have access to for:
- Core Functionality: Storing and syncing your habits across your devices via iCloud
- Subscription Management: Verifying your premium subscription status via RevenueCat
- Notifications: Sending local reminders you've configured (processed entirely on your device)
We do not:
- Use your data for advertising
- Build user profiles
- Perform behavioral analytics
- Train AI models with your data
- Share or sell your data to third parties
