Privacy Policy

Effective Date: February 1, 2026

Introduction

We are committed to protecting your privacy and being transparent about how we handle data. By using Double Jump, you agree to this Privacy Policy.

1. Information We Collect

Information We DO NOT Collect

We do not collect, store, or process:

  • Phone number
  • Physical address
  • Payment information (handled entirely by Google Play)
  • Account credentials or passwords

Information Collected via Google Sign-In

If you choose to sign in with Google, we receive and store:

  • Display name
  • Email address
  • Google account identifier (UID)

This information is used solely for authentication, cloud backup, and cross-device sync. We do not access any other Google account data.

Information We Automatically Collect

We collect limited technical and usage data to improve app performance and user experience:

Google Analytics & Firebase

We use Google Analytics for Firebase to understand how users interact with our app. This may include:

  • Device information (model, operating system version, unique device identifiers)
  • App usage data (screens visited, features used, session duration)
  • Approximate location (country/region level, derived from IP address)
  • Crash reports and performance data (via Firebase Crashlytics)

Important: This data is anonymized and aggregated. We cannot identify individual users from this information.

Feedback Submissions

When you submit feedback through the app, we may include your Firebase user identifier (UID) along with device and app version information. This is used solely for troubleshooting purposes — to help us identify and resolve issues specific to your account or device. Your UID is not shared with any third parties and is only used internally for technical support.

Local Storage

We store the following data locally on your device:

  • Your game collections (Release Radar and custom collections)
  • App preferences (dark mode, notification settings)
  • Cached game data for offline viewing
  • Purchase status (ad-free membership)

If you sign in with Google, your collections and purchase status are also backed up to our cloud servers for cross-device sync.

2. Third-Party Services

Google AdMob (Advertising)

We display advertisements through Google AdMob. AdMob may collect:

  • Device information and advertising identifiers
  • Interaction with ads
  • App usage data for personalized advertising

You can opt out of personalized ads:

  • Android: Settings > Google > Ads > Opt out of Ads Personalization
  • iOS: Settings > Privacy > Advertising > Limit Ad Tracking

Google Analytics & Firebase

We use Firebase to analyze app usage and crashes. Firebase may collect:

  • Analytics data (app interactions, device info)
  • Crash logs and performance metrics

Cloud Firestore (Data Storage)

We use Cloud Firestore to cache game information for faster loading. If you sign in with Google, Firestore also stores your game collections and purchase status for cloud backup and cross-device sync. This data is associated with your Google account identifier.

IGDB (Internet Game Database)

We fetch game information from IGDB API. We do not send any user data to IGDB. We only request publicly available game data (titles, release dates, images, etc.).

3. How We Use Information

We use the collected information solely for:

  • App functionality: Providing game data, collections, and notifications
  • Performance improvement: Identifying and fixing crashes and bugs
  • Analytics: Understanding user behavior to improve features
  • Advertising: Displaying relevant ads to support free app development
  • Troubleshooting: Using your Firebase UID from feedback submissions to diagnose and resolve account-specific or device-specific issues

We do NOT:

  • Sell your data to third parties
  • Use your data for marketing purposes
  • Share your data with other companies (except third-party service providers mentioned above)

4. Data Retention

  • Analytics & Crash Data: Automatically deleted by Google Firebase according to their retention policies (typically 2-14 months)
  • Local Data: Stored on your device until you uninstall the app or clear app data
  • Advertising Data: Managed by Google AdMob according to their policies

5. Age Requirement

Double Jump is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13.

If you are under 13 years of age, please do not use this app. If you are a parent or guardian and believe your child under 13 has used this app, please contact us at [email protected]

6. Your Rights and Choices

Data Access and Deletion

Since we do not collect personal information, there is no personal data to access or delete. However, you can:

  • Reset Advertising ID: Settings > Google > Ads > Reset Advertising ID
  • Clear Local Data: Uninstall the app or clear app data in device settings

Opt-Out of Tracking

  • Opt out of personalized ads: See Section 2 above
  • Limit analytics tracking: Settings > Google > Usage & Diagnostics (varies by device)

European Economic Area (EEA) Users (GDPR)

If you are located in the EEA, you have the right to:

  • Access the data we hold about you
  • Request deletion of your data
  • Object to data processing
  • Withdraw consent

Note: Since we do not collect personal data, most GDPR rights do not apply. However, third-party services (Google AdMob, Firebase) have their own GDPR-compliant policies.

California Users (CCPA)

California residents have the right to:

  • Know what personal information is collected
  • Request deletion of personal information
  • Opt out of the sale of personal information

We do not sell personal information.

7. Data Security

We take reasonable measures to protect data:

  • Encryption: Data transmitted between the app and Firebase is encrypted using HTTPS/TLS
  • No Personal Data Storage: We do not store personal information, minimizing risk
  • Third-Party Security: We rely on industry-leading security from Google (Firebase, AdMob)

However, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security.

8. International Data Transfers

Your data may be processed in countries outside your own, including the United States, where Google's servers are located. By using Double Jump, you consent to the transfer of information to countries outside of your residence.

Google complies with applicable data protection laws, including GDPR and Privacy Shield frameworks.
