This Privacy Policy applies to All Clean, an Android application developed and published by 2X Happiness. It explains how we handle data related to you.

3. What Data We Process

3.1 Data Processed Locally on Device (Not Uploaded by Default)

To provide features such as junk cleanup, duplicate file detection, large file detection, and APK management, the app reads and analyzes file-related information on your device locally, for example:

• File path, file name, size, modified time, media type
• Index information in system media library (MediaStore) for images/videos/audio
• Cleanup statistics, such as total space freed, cleanup count, and item count, stored locally only
• Theme preference settings, stored locally only

These data are mainly processed on your device to present scan results and perform deletion operations.

3.2 Data That May Be Transmitted to Third Parties (SDKs)

This app integrates third-party SDKs that may transmit certain data to their servers:

• Google AdMob (Advertising): May process advertising identifiers such as AAID, device identifier information, IP address, ad interaction data, and coarse device information for ad delivery, anti-fraud, and performance measurement.
• Firebase Analytics (Analytics): May process app events, device and app version information, and crash/performance-related metrics, depending on enabled SDK features.

Third parties may process data in different regions according to their own policies. Please also review their privacy policies.

3.3 Permissions and Purpose

This app may request the following permissions:

• READ_MEDIA_IMAGES, READ_MEDIA_VIDEO, READ_EXTERNAL_STORAGE (<= Android 12): used to scan media files.
• MANAGE_EXTERNAL_STORAGE: used for deep storage scanning and cleanup, for example when you actively trigger full-disk cleanup.

We use permissions only to the extent necessary for core functionality.

4. Legal Bases for Processing (GDPR)

If you are located in the EU/EEA or other applicable regions, we process data based on:

• Contract performance (GDPR Art. 6(1)(b)): to provide requested cleanup and file management features.
• Legitimate interests (GDPR Art. 6(1)(f)): to ensure app security, stability, anti-abuse, and basic analytics.
• Consent (GDPR Art. 6(1)(a)): where legally required, for example personalized advertising/tracking, through compliant consent mechanisms.
• Legal obligation (GDPR Art. 6(1)(c)): to comply with legal requirements.

5. Data Sharing and Disclosure

We do not sell your personal data.

Data may be shared when necessary:

• With third parties providing technical services, such as Google AdMob/Firebase, for necessary processing;
• To comply with laws, judicial orders, or regulatory requirements;
• To protect the lawful rights and interests of users or the public.

6. Cross-Border Transfers

Due to global infrastructure used by third-party service providers, your data may be transferred to countries/regions outside your own.

We require relevant parties to implement appropriate safeguards, such as standard contractual clauses or other compliant mechanisms.

7. Data Retention

• Local scan results and statistics: usually retained on your device until you clear app data or uninstall the app.
• Third-party SDK data: retained and deleted by corresponding providers under their policies.
• Data required by law: retained for the legally required period.

8. Your Rights (GDPR)

Under applicable law, you may have the right to:

• Access, rectify, and erase your data;
• Restrict or object to processing, and data portability;
• Withdraw consent without affecting the lawfulness of processing before withdrawal;
• Lodge a complaint with a supervisory authority.

You may submit requests through the contact details in this Policy. To remove local data, you can uninstall the app or clear app data in system settings.

9. Children's Privacy

This app is not directed to children under 13 years old, or the legal minimum age in your jurisdiction. If a guardian finds that a minor has provided personal data without authorization, please contact us for handling.

10. Security Measures

We implement reasonable technical and organizational measures to protect data security, but no transmission or storage method can guarantee absolute security.
