Privacy Policy
Last Updated: August 18, 2026
Cool Cleaner ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our iOS application Cool Cleaner (the "App").
1. Information We Collect
We design our App with privacy in mind. We collect minimal data necessary to provide our services:
- Photo Library Access: The App accesses your photo library locally on your device to identify duplicate, similar, and large media files. Your photos and videos are never uploaded to our servers.
- Contacts Access: If you use the contact management feature, the App reads your contacts locally to find duplicates. Contact data stays on your device.
- Calendar Access: If you use calendar cleanup, the App reads calendar events locally to identify expired entries.
- Analytics Data: We use Firebase Analytics to collect anonymized usage data such as feature usage frequency, app performance metrics, and crash reports. This data does not identify you personally.
- Advertising Data: We use Google AdMob to display advertisements. AdMob may collect device identifiers and usage data for ad personalization as described in Google's privacy policy.
2. How We Use Your Information
- To provide and improve the App's functionality
- To analyze usage patterns and optimize performance
- To display relevant advertisements
- To diagnose and fix technical issues
3. Data Storage & Security
All photo, video, contact, and calendar data is processed locally on your device. We do not upload, store, or transmit your personal media or contacts to any external servers. Analytics data is stored securely on Firebase servers with industry-standard encryption.
4. Third-Party Services
Our App integrates the following third-party services, each with their own privacy policies:
- Firebase Analytics: For anonymized app usage analytics. Firebase Privacy Policy
- Google AdMob: For displaying advertisements. Google Privacy Policy
- Apple App Store: For subscriptions and purchases. Apple Privacy Policy
5. App Tracking Transparency
In compliance with Apple's App Tracking Transparency (ATT) framework, we request your permission before tracking your activity across other companies' apps and websites. You can change this preference at any time in your device's Settings.
6. Children's Privacy
Our App is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.
7. Your Rights
You have the right to:
- Opt out of personalized advertising through your device settings
- Revoke photo, contact, or calendar access permissions at any time
- Request deletion of any analytics data associated with your device
- Contact us with questions about your data
8. Data Retention
We retain anonymized analytics data for up to 14 months. No personal data is retained on our servers as all processing occurs locally on your device.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy within the App or on this page. Your continued use of the App after changes constitutes acceptance of the updated policy.
