Privacy Policy

Welcome to Nexus Core Games. We are a mobile app publishing company focused on creating secure, user-friendly, and high-performance applications. Your privacy is our priority, and we are committed to handling your data responsibly and transparently.

By using our applications (“apps”), you agree to the practices described in this Privacy Policy.

1. Scope of This Policy

This Privacy Policy applies to all mobile applications published by Apps Hub, including but not limited to:

• PDF Reader

• And other apps released under our developer account.

Our apps may collect limited data to ensure proper functionality, improve performance, and support advertising services.

2. Legal Basis for Data Processing

We process data based on globally accepted principles:

Contractual Necessity (GDPR Art. 6(1)(b))

To provide essential app functions and user-requested features.

Legitimate Interests (GDPR Art. 6(1)(f))

To maintain app performance, security, analytics, and error prevention.

We ensure these interests never override user rights.

3. Data We Collect & How We Use It

We collect only the minimum information required for app functionality.

a) Personal Information

We do not collect any sensitive or unnecessary personal data.

b) Precise or Approximate Location (Only When Required)

Some features may request location permission.

• Used only for feature functionality.

• Not stored, sold, or shared.

• Users may disable it anytime via device settings.

c) Device & Usage Data

Automatically collected for performance, analytics, and stability:

• Device type, OS version, model

• IP (temporarily for security)

• App activity & diagnostics

• Crash logs

• Advertising identifiers (for ads)

This data helps improve app performance and user experience.

d) Contacts Permission (Only in Relevant Apps)

If a feature needs access to contacts (e.g., share functionality), permission is requested explicitly.

• Contacts are never uploaded, never shared, and remain on your device.

4. Data Retention

We retain data only for the period required for:

• App functionality

• Security

• Diagnostics

• Legal or compliance obligations

After the purpose is completed, data is permanently deleted.

5. User Rights (GDPR, CCPA, VCDPA, LGPD)

Depending on your region, you may:

• Request access to your data

• Request correction

• Request deletion

• Request restriction of processing

• Opt out of personalized ads

• File a complaint with your local authority

For requests, contact: cleaningexpert60@gmail.com

6. Advertising & Opt-Out Options

Some apps are supported through advertising.

a) Personalized Ads

Users may disable personalized advertising via:

• Google My Ad Center

• Device ad settings

• App-level privacy settings (where supported)

Disabling personalization does not remove ads but stops interest-based targeting.

b) Sale of Personal Data

Apps Hub does not sell personal data.

c) Automated Profiling

Our apps do not perform automated decision-making that affects users legally or significantly.

7. Third-Party Services & SDKs

To provide functionality, analytics, and ads, we use trusted partners:

• Google Play Services

• AdMob

• Google Analytics for Firebase

• Firebase Crashlytics

• Firebase Remote Config

These services may collect non-identifiable data per their privacy policies.

Permissions requested by SDKs are limited to technical use and do not allow sensitive data collection.

8. Data Processing Operations

a) Firebase Hosting

Stores content and logs IP addresses temporarily for abuse detection and security.

b) Google AdSense / AdMob

Used for advertising.

• Limited data (IP, device info) may be used for fraud prevention.

• Data is anonymized after Google’s retention period.

c) Firebase Analytics

Collects anonymized usage data to improve app performance.

• Users can disable Analytics in settings (if available).

• Retention follows Google’s analytics policies.

d) Crashlytics

Stores crash-related data for debugging.

• Data is anonymous.

• Retained for up to 3 years.

e) Remote Config

Stores temporary configuration values for better user experience.

9. External Links & Affiliate Information

Some apps (such as barcode scanners) may display external product links.

• Only necessary details (e.g., barcode number or basic request info) may be shared to load relevant content.

• We may participate in affiliate programs and earn commissions at no extra cost to the user.

• Users may disable external link features in app settings.

10. Email Communication

When users contact us at cleaningexpert60@gmail.com, we use the information solely to respond.
All emails and related data are deleted after resolution.

11. Children’s Privacy

Our apps are not intended for children under 13.
We do not knowingly collect information from minors.
If you believe data has been collected from a child, contact us immediately.

12. Policy Updates

We may update this Privacy Policy due to:

• Legal obligations

• SDK changes

• Google Play requirements
