Privacy Policy
This policy applies to all applications developed and published by Ryusoft-Dev on the Google Play Store.
1. Introduction
Ryusoft-Dev ("we", "us", or "our") operates and publishes multiple applications on the Google Play Store. This Privacy Policy informs you ("user" or "you") about how we collect, use, and protect your information when you use any of our applications.
By downloading, installing, or using any of our applications, you agree to the terms of this Privacy Policy. If you do not agree, please do not use our applications.
This policy covers all applications published under the Ryusoft-Dev developer account on Google Play Store.
2. Information Collection & Use
Our applications do not require you to create an account or provide personal information such as your name, email address, or phone number. We do not directly collect, store, or process any personally identifiable information (PII).
However, our applications use third-party services that may automatically collect certain information:
- Device information — model, manufacturer, OS version, screen resolution
- App usage data — app opens, session duration, feature interactions
- Crash & performance data — error logs, stack traces, performance metrics
- Advertising identifiers — for serving relevant advertisements
- IP address — collected automatically by third-party services (not stored by us)
3. Third-Party Services
Our applications integrate the following third-party services, each with its own privacy policy:
| Service | Purpose | Policy |
|---|---|---|
| Google AdMob | Displaying advertisements | View |
| Firebase Analytics | App usage analytics | View |
| Firebase Crashlytics | Crash reporting | View |
| Google Play Services | Core Android functionality | View |
4. Advertisements
Some of our applications display advertisements provided by Google AdMob. These ads help us keep our applications free. AdMob may use cookies, device identifiers, and advertising IDs to serve personalized or non-personalized ads.
Types of Ads
- Banner Ads — displayed at the top or bottom of the screen
- Interstitial Ads — full-screen ads at natural transition points
- Rewarded Ads — optional ads users watch for in-app rewards
- Native Ads — ads matching the look and feel of the application
Ad Personalization
You can opt out of personalized advertising:
- On Android: Settings → Google → Ads → Opt out of Ads Personalization
5. App Permissions
Depending on the application, we may request certain permissions for core functionality:
| Permission | Purpose | Scope |
|---|---|---|
| INTERNET | Access online content, serve ads, send analytics | All apps |
| ACCESS_NETWORK_STATE | Check network connectivity | All apps |
| SET_WALLPAPER | Set images as device wallpaper | Wallpaper apps |
| WRITE_EXTERNAL_STORAGE | Save wallpapers to storage (Android 9 and below) | Wallpaper apps |
| READ_EXTERNAL_STORAGE | Access saved wallpapers (Android 9 and below) | Wallpaper apps |
We only request permissions strictly necessary for each app's intended functionality. You can manage permissions in Settings → Apps.
6. Data Security
We value your trust and take appropriate measures to protect data processed through our applications:
- Secure HTTPS connections for all data transmissions
- Firebase and Google's enterprise-grade security infrastructure
- Minimal data collection — only what is strictly necessary
- No personally identifiable information stored on our servers
7. Children's Privacy
Our applications are not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided personal data, we will promptly delete it.
If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
8. Data Retention
Since we do not directly collect or store personal data, there is no personal data retention on our end. Data collected by third-party services is retained according to their respective policies.
See Google's Data Retention Policy for more details.

- Right to Access — request information about data collected about you

10. Changes to This Policy
We may update this Privacy Policy to reflect changes in our practices, third-party services, or laws. When we make significant changes, we will update the "Last Updated" date at the top.
Continued use of our applications after modifications constitutes acceptance of those changes. We recommend reviewing this policy periodically.
