Privacy Policy

Last updated: October 2025

Storage Cleaner (“we,” “our,” or “us”) is developed and operated by NextStack LLC. This Privacy Policy explains how we handle your information when you use our mobile application available on Android and iOS.

1. Information We Collect

1.1 Permissions

• Gallery / Storage Access: Required to detect duplicate photos, videos, and screenshots stored on your device. All processing happens locally on your device — no media files are uploaded to our servers.
  
  

• Contacts Access: Required to identify duplicate contacts. This data is processed entirely on your device and is never transmitted to us or any third party.
  
  

1.2 Automatically Collected Information

We use third-party services (listed below) that may collect limited data automatically for analytics, diagnostics, and advertising purposes, such as:

• Device type and operating system
  
  

• Country and language
  
  

• App usage events (e.g., feature usage, session length)
  
  

• Advertising identifiers (used for personalized ads)
  
  

• Crash logs and performance data

2. How We Use Information

We use collected data only for the following purposes:

• To monitor and improve app stability and performance
  
  

• To understand aggregated usage trends through analytics
  
  

• To display relevant in-app advertisements (via Google AdMob)
  
  

We do not sell, rent, or share any personal data with third parties for their own marketing purposes.

3. Data Storage and Retention

• All user media (photos, videos, contacts) are analyzed locally on your device and never leave your phone.
  
  

• We do not store or maintain copies of your personal data on our servers.
  
  

• Analytics and diagnostic data collected by third-party services are retained according to their respective policies.
  
  

4. Third-Party Services

The app integrates with the following third-party providers:

• Google AdMob – for serving advertisements
  
  

• Firebase Analytics & Crashlytics – for analytics and crash reporting
  
  

• Google Analytics – for aggregated performance metrics
  
  

These providers may automatically collect certain technical data (such as advertising IDs, usage statistics, or crash logs). Each service has its own privacy policy:

• Google Privacy Policy
  
  

• Firebase Privacy Policy

5. Subscriptions and Payments

• All payments and subscriptions are handled securely by Google Play or Apple App Store.
  
  

• We do not collect or store any payment or personal billing information.
  
  

• Users can manage or cancel subscriptions directly through their respective app store accounts.
  
  

6. Children’s Privacy

Storage Cleaner is not directed toward individuals under the age of 13 (or equivalent minimum age in your jurisdiction). We do not knowingly collect any information from children.

7. Your Privacy Rights

Depending on your region (e.g., European Economic Area or California), you may have rights to:

• Request access to or deletion of personal data collected by third-party services
  
  

• Opt out of personalized advertising through your device settings
  
  

• Withdraw consent by uninstalling the app
  
  

As Storage Cleaner itself does not store user data, such requests can be directed to the third-party providers listed above.

8. Data Security

We apply reasonable measures to protect data processed within the app, however, since all processing occurs locally, users are responsible for safeguarding their own device and data.

9. Changes to This Policy

We may update this Privacy Policy periodically. Updates will be published within the app or on our website. Continued use of the app after any modification constitutes your acceptance of the new terms.
