Kwai Games ("we," "us," or "our") built Paper Plane Traveler as a free-to-play game with optional in-app purchases. This Privacy
Policy explains what information we collect, how we use it, and your rights regarding that information.
1. Information We Collect
We collect minimal information to provide the game experience:
- Anonymous Identifier: When you first open the game, a random anonymous ID is created through Firebase Anonymous Authentication.
This ID is not linked to your name, email, phone number, or any personal information.
- Game Progress Data: We store your in-game progress (coins, upgrades, scores, settings, and selected skins) to allow you to
restore your progress across devices.
- Auto-Generated Player Name: A random, computer-generated display name (e.g., "SwiftEagle_42") is assigned for leaderboard
purposes. This is not your real name and cannot be used to identify you.
- Leaderboard Data: Your best scores, in-game distances, and in-game location names (fictional cities within the game world, not
your real-world location) are stored for the public leaderboards.
- Purchase Verification: If you make an in-app purchase, the purchase token from Google Play is verified server-side. We do not
collect or store payment details such as credit card numbers.
2. Information We Do NOT Collect
- Real names, email addresses, or phone numbers
- Real-world location or GPS data
- Photos, contacts, or device files
- Advertising identifiers
- Analytics or tracking data
3. How We Use Information
We use the collected information solely to:
- Save and restore your game progress across devices
- Display public leaderboard rankings
- Verify in-app purchases
- Prevent fraud and abuse
4. Third-Party Services
We use the following third-party services:
- Google Firebase (Anonymous Authentication, Realtime Database, Cloud Functions) — to store game data and verify purchases.
Firebase's privacy policy: https://firebase.google.com/support/privacy
- Google Play Billing — to process in-app purchases. Google's privacy policy: https://policies.google.com/privacy
We do not use any advertising, analytics, or tracking services.
5. Children's Privacy
Paper Plane Traveler is suitable for all ages, including children under 13. We comply with the Children's Online Privacy
Protection Act (COPPA) and similar regulations:
- We do not collect personal information from children or any users.
- The anonymous ID assigned to each player cannot be used to identify any individual.
- Player names are auto-generated and contain no personal information.
- No real-world location data is collected — all locations in the game are fictional.
- We do not serve targeted advertising.
- We do not share any data with third parties for marketing purposes.
6. Data Storage and Security
Game data is stored on Firebase servers located in the European Union (Belgium). We use Firebase security rules to ensure each
player can only access their own data. Leaderboard rankings are publicly visible but contain only auto-generated names and game
scores.
7. Data Retention and Deletion
Your game data is retained as long as you use the app. You can reset your progress at any time using the "Reset Progress" option
within the game. To request complete deletion of your data from our servers, contact us at supportkwai@gmail.com.
8. Your Rights
You have the right to:
- Request access to your stored data
- Request deletion of your data
- Reset your game progress at any time within the app
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
