Privacy Policy
Last updated: January 24, 2026

1. Introduction Contact Cleaner ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how your information is collected, used, and safeguarded when you use our mobile application.

2. Information Collection and Use
Google Authentication: We use Google Sign-In to authenticate users. When you sign in, we receive basic profile information (such as your email address) to create and manage your account.
Contact Data & Cloud Backups: If you choose to use our cloud backup feature, your contact information is uploaded to and stored securely on Google Firebase servers. This data is used solely to provide backup and restore services to you.
Analytics: We use Firebase Analytics to collect anonymous information about how the app is used (e.g., screen views, button clicks). This data is aggregated and does not personally identify you. It helps us improve the app experience.

3. Data Storage and Security Your data is stored using industry-standard security measures provided by Google Firebase. We prioritize the security of your information, but please remember that no method of transmission over the internet or electronic storage is 100% secure.

4. User Rights and Data Deletion You have full control over your data. You can:
Delete individual backups at any time within the app.
Permanently delete your account: By using the "Delete Account" feature inside the app settings, all your information associated with your Google account—including all cloud backups and account metadata—will be permanently erased from our Firebase servers.

5. Service Providers We use third-party services (Google Firebase) that may collect information used to identify you according to their own privacy policies:
Google Play Services (https://policies.google.com/privacy)
Firebase Analytics (https://firebase.google.com/policies/analytics)

6. Changes to This Privacy Policy We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
