1. Introduction

Welcome to Leyner Jesus Castillo Guedez ("we," "our," or "us"), operating as GuaroDev. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application (the "App"). Our App is designed to work completely anonymously - no account creation is required, and all your data is stored locally on your device. Please read this privacy policy carefully.

2. Information We Collect

2.1 Local Data Storage

Our App is designed to work completely offline and anonymously. All data you create in the app is stored locally on your device and is not transmitted to our servers or any third parties. This includes:

  • Score and Performance Data: Scores, rankings, and performance metrics for competitions and leaderboards
  • Photos and Media: Images you upload for competitions or competitors
  • App Settings: Your personal preferences and configuration settings

2.2 Analytics Information (Optional)

We may collect anonymous, aggregated analytics data to help us improve the app. This data does not identify you personally and may include:

  • Usage Statistics: Anonymous information about which features are used most frequently
  • App Performance: Technical data to help us identify and fix bugs
  • Device Information: General device type and operating system version (no personal identifiers)

Important: You can opt out of analytics data collection in the app settings if you prefer complete privacy.

3. How We Use Your Information

3.1 Local Data Usage

Since all your data is stored locally on your device, we do not have access to your personal information, competitions, or any other data you create in the app. Your data is used solely by the app on your device to:

  • Enable you to create and manage competitions
  • Add and manage competitors
  • Track and display scores, rankings, and performance metrics
  • Store and display photos you upload
  • Maintain your app preferences and settings

3.2 Analytics Usage (If Enabled)

If you choose to enable analytics, we may use anonymous, aggregated data to:

  • Improve app performance and fix bugs
  • Understand which features are most useful to users
  • Enhance the overall user experience

4. Information Sharing and Disclosure

4.1 No Data Sharing

We do not share, sell, or transmit any of your personal data, competitions, or other information to third parties. Since all your data is stored locally on your device, we have no access to it and cannot share it.

4.2 Analytics Data (If Enabled)

If you enable analytics, we may share anonymous, aggregated usage statistics with analytics service providers to help us improve the app. This data cannot be used to identify you personally.

4.3 Legal Requirements

Since we do not collect or store personal data, there is no personal information to disclose in response to legal requests. Any data you create remains on your device and is not accessible to us.

5. Data Security

5.1 Local Data Security

Since all your data is stored locally on your device, the security of your information depends on your device's security settings and your own practices. We recommend:

  • Keeping your device's operating system updated
  • Using device lock screens and biometric authentication
  • Being cautious about who has access to your device
  • Regularly backing up your device if you want to preserve your data

5.2 App Security

We implement appropriate security measures within the app to protect your locally stored data, including secure storage mechanisms and data encryption where applicable.

6. Your Rights and Choices

6.1 Complete Control Over Your Data

Since all your data is stored locally on your device, you have complete control over it. You can:

  • Access: View all your data directly within the app
  • Modify: Edit, update, or correct any information at any time
  • Delete: Remove competitions, competitors, or any other data whenever you want
  • Export: Your data remains on your device and can be backed up through your device's backup system
  • Privacy: No data is transmitted to us or any third parties

6.2 Analytics Control

If you enable analytics, you can opt out at any time through the app settings. This will stop all anonymous data collection.

7. Data Retention

7.1 Local Data Retention

Your data is stored locally on your device and will remain there until you delete it through the app or uninstall the app. We do not have access to your data, so we cannot delete it for you. You have complete control over how long your data is retained.

7.2 Analytics Data Retention

If you enable analytics, anonymous usage data may be retained for up to 24 months to help us improve the app. This data cannot be used to identify you personally.

8. Children's Privacy

Our App is not intended for children under 13 years of age. Since we do not collect any personal information and all data is stored locally on the user's device, there is no personal information to collect from children. Parents and guardians should be aware that any data created by children using the app will be stored locally on their device.

9. International Data Transfers

Since all your data is stored locally on your device and we do not collect personal information, there are no international data transfers of your personal data. Any anonymous analytics data (if enabled) may be processed in different countries, but this data cannot be used to identify you personally.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. Since we do not collect personal information, changes to this policy will not affect your existing data, which remains stored locally on your device.
