Last Updated: November 4, 2025
1. Introduction
Welcome to Wonndo. We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, and safeguard your data when you use our application.
Wonndo is designed with privacy in mind. We believe in minimal data collection and maximum user control over personal information.
2. Information We Collect
Wonndo collects minimal information to provide you with the best learning experience. We only collect:
2.1 User ID
We collect a unique user identifier to manage your account and subscription status. This ID is automatically generated and does not contain any personally identifiable information.
2.2 Subscription Information
We collect information about your subscription status to provide you with premium features. This includes:
- Subscription tier (Weekly, Monthly, Quarterly, or Yearly)
- Subscription start and expiration dates
- Subscription status (active or inactive)
2.3 Information We DO NOT Collect
We want to be clear about what we do not collect:
- Personal information (name, email, phone number, address)
- Location data
- Device information beyond basic system requirements
- Browsing history or app usage analytics
- Contacts or photos from your device
- Any other personally identifiable information
3. Data Storage
All your learning data, including diary entries, study progress, and preferences, are stored locally on your device. This means:
- Your diary entries never leave your device
- Your study history is private and secure
- Your learning preferences are stored locally
- We do not have access to your personal learning content
The only data transmitted to our servers is your User ID and subscription status, which is necessary for managing your subscription and providing premium features.
4. How We Use Your Information
The limited information we collect is used solely for:
- Managing your subscription and providing premium features
- Verifying your subscription status
- Processing subscription renewals and cancellations
- Providing customer support when requested
We do not use your information for advertising, marketing, or any other purposes beyond providing our core services.
5. Data Sharing and Third Parties
We do not sell, trade, or share your personal information with third parties. The only exception is:
- Apple App Store: Subscription transactions are processed through Apple's payment system. Apple's privacy policy governs how they handle payment information.
We do not share your User ID or any other information with third-party advertisers, data brokers, or analytics companies.
6. Data Security
We implement industry-standard security measures to protect your information:
- Encrypted data transmission using HTTPS
- Secure storage of subscription information
- Regular security audits and updates
- Limited access to user data by authorized personnel only
Since most of your data is stored locally on your device, you maintain direct control over its security.
