1. Introduction
Welcome to MZR DNS, a DNS changer application for Android developed by Zain Riaz (MZR). This Privacy Policy explains how we handle information when you use our app available on the Google Play Store.
MZR DNS is designed to help you switch DNS servers for enhanced privacy and security. We are committed to protecting your privacy and being transparent about our data practices.
Key Principle: We believe in minimal data collection. We do not collect, store, or track your DNS queries or browsing history. Your internet activity remains private.
2. Information We Collect
2.1 Information We DO Collect
Device Information
We collect basic device information including your Android version and device model to ensure app compatibility and optimal performance.
DNS Statistics
Connection statistics such as query count and uptime are collected and stored locally on your device only. This data never leaves your device.
Crash Reports
We use Firebase Crashlytics to collect anonymous crash reports and diagnostic information to identify and fix bugs quickly.
Country Location
We detect your country based on your IP address to recommend optimal DNS servers closest to your location for better performance.
2.2 Information We DO NOT Collect
- Personal information such as your name, email address, or phone number
- DNS query content or browsing history
- Website addresses you visit
- Contacts, photos, or other media files
- Payment information (the app is completely free)
- Location data beyond country-level detection
- Any personally identifiable information (PII)
3. How We Use Your Information
The limited information we collect is used exclusively for the following purposes:
- App Functionality: To ensure MZR DNS works properly on your device and to provide DNS server recommendations based on your country.
- Performance Improvement: To analyze crash reports and fix bugs to improve app stability and user experience.
- Statistics Display: To show you local statistics about your DNS usage directly within the app (this data stays on your device).
- Compatibility: To ensure the app functions correctly across different Android versions and device models.
Important: All DNS connection statistics are stored locally on your device and are never transmitted to our servers or any third party. You have complete control over this data.
4. Third-Party Services
MZR DNS uses the following third-party services:
4.1 Firebase (Google)
We use Firebase services provided by Google for:
- Firebase Crashlytics: To collect anonymous crash reports and performance data
- Firebase Cloud Messaging: To send push notifications about app updates or important announcements
Firebase may collect certain device information and usage data. Please review Google's Firebase Privacy Policy for more information.
4.2 IP Geolocation API
We use an IP geolocation service to detect your country location only. This helps us recommend DNS servers that are geographically closer to you for better performance. No precise location data is collected or stored.
5. Data Storage and Security
We take the security of your information seriously:
- Local Storage: DNS statistics and app preferences are stored locally on your device using secure Android storage mechanisms.
- No Central Database: We do not maintain a central database of user information or DNS queries.
- Encryption: Any data transmitted to third-party services (like crash reports) is encrypted during transmission.
- No Data Selling: We do not sell, rent, or trade any user data to third parties.
- Limited Access: Only the app developer has access to aggregated, anonymous crash reports for debugging purposes.
6. Your Rights and Choices
You have the following rights regarding your information:
- Access Local Data: You can view your DNS statistics within the app at any time.
- Delete Data: You can clear all locally stored statistics through the app settings or by uninstalling the app.
- Opt-Out of Crash Reports: You can disable crash reporting in the app settings if you prefer not to send diagnostic information.
- Notification Control: You can disable push notifications through your device's system settings or within the app.
- Data Portability: Since all data is stored locally on your device, you have complete control over it.
