1. Introduction & Consent

This Privacy Policy applies to JunkEraseCase Storage Cleaner (“JunkEraseCase”, “we”, “our App”), an Android storage optimization and junk file cleanup utility available on Google Play Store. This document explains our full standards for collecting, processing, storing and protecting user data during your use of the application.

By downloading, installing, launching JunkEraseCase and executing storage scanning or cleanup operations, you fully acknowledge and accept all terms within this policy. If you disagree with any provisions, you must uninstall JunkEraseCase and cease all usage immediately.

JunkEraseCase strictly complies with Google Play User Data Policy, Google Data Safety requirements, EU GDPR, California CCPA and US COPPA regulations. All core file scanning and cleanup logic runs locally on your device by default; we will never automatically upload your private photos, documents and personal files to remote cloud servers without your voluntary separate consent.

2. Information We Collect

2.1 Data You Voluntarily Submit

• Feedback messages and device descriptions submitted via in-app support forms to report scanning compatibility failures or functional bugs
• Optional email address provided voluntarily only to receive follow-up replies to your support tickets
• Local user preferences including scan filter rules, file sorting settings and temporary scan cache, which are only stored on your mobile device

2.2 Automatically Collected Anonymous Technical Data

• Device system metadata: Android OS version, device model, JunkEraseCase build version, total and remaining storage capacity
• Anonymous advertising ID: Used to serve non-targeted free in-app advertisements; users can fully opt out via Android system privacy settings
• Aggregated crash and performance logs: De-identified error reports to resolve scanning crashes and compatibility issues; logs contain no raw private file or media content
• Non-personal anonymous usage statistics: Records of scan frequency, cleaned file volume and feature click behavior, which cannot be linked to individual user identities

2.3 Local File Metadata Accessed for Core Cleaning Features

JunkEraseCase requires storage access to traverse device storage and identify junk files, residual app cache, duplicate media, unused APK packages and oversized redundant files. The App only reads file metadata including names, sizes, formats and storage paths to classify junk items for manual user deletion. We never parse or read the internal text, image or confidential content of your private documents and personal photos. All file analysis processes are completed locally on your device without automatic cloud upload.

2.4 Categories of Data We Never Collect

• Contacts, SMS messages, call history, calendar records, real-time background location tracking data
• Bank card numbers, online banking login credentials, identity documents and all high-risk financial sensitive data
• Third-party app login accounts, private chat records and internal confidential content stored inside other installed applications

3. Legitimate Purposes of Data Processing

All collected information is processed solely for limited service-related purposes, and we will not reuse data outside the listed scope without your separate explicit written consent:

• Deliver core storage cleanup services: Scan redundant junk cache, classify duplicate media and list unused large files to help users release device storage space after manual deletion confirmation
• Optimize App performance and device compatibility: Fix scanning crashes, accelerate full-storage scan speed and adapt functions for various Android device brands and system versions
• Maintain free App operation: Display contextual advertisements through integrated Google AdMob SDK; scanned file metadata will never be used for targeted ad matching
• Process user technical support requests: Receive and respond to scan failure reports, feedback and troubleshooting inquiries submitted by users
• Fulfill legal obligations and all Google Play platform compliance requirements

JunkEraseCase will never sell, rent, trade or license your device metadata and scanned file information to advertisers, data brokers or any third-party commercial institutions for profit.

4. Third-Party SDK & Data Sharing Rules

JunkEraseCase only shares anonymized non-personal technical statistical data with essential third-party service vendors. All cooperative partners sign legally binding data protection agreements prohibiting unauthorized disclosure of user device and file information.

Integrated Third-Party SDKs

• Google Firebase Crashlytics: Collect anonymous crash logs for bug repair and performance optimization; cannot access local private media, documents or full storage files stored on your device
• Google AdMob: Deliver free in-app contextual advertisements, process advertising ID to control ad display frequency and repetitive pop-ups
• Google Play Billing: Process premium ad-free upgrade subscription orders; all payment transaction data is fully managed and stored by Google, never cached or saved by JunkEraseCase

Mandatory Legal Data Disclosure Scenarios

We may disclose anonymized aggregated device statistical data upon receiving valid court orders, official government regulatory requests, or when disclosure is necessary to protect platform security, our legal rights and user data safety.

5. Data Storage & Retention Standards

• Temporary scan cache: Local file scanning indexes and preview records are saved inside JunkEraseCase’s private app directory and automatically cleared once you fully close the App
• Anonymous crash & usage logs: Retained for a maximum of 12 months for product iteration optimization, then permanently purged from all backend storage automatically
• User feedback support records: Messages submitted by users are stored for 90 days to handle follow-up inquiry replies, then completely deleted
• Local user scan preferences: Filter and cleanup rules saved exclusively on your device, retained until you manually clear App storage or uninstall JunkEraseCase

JunkEraseCase does not enable automatic cloud synchronization of local device files by default. All scanned file metadata stays only on your mobile device without remote transmission.

6. Data Security Protection Measures

We deploy industry-standard technical and administrative safeguards to protect anonymous device data and local scanned file records against unauthorized access, leakage, tampering and permanent loss:

• All network data transmission between your device and third-party SDK backend servers adopts TLS 1.3 end-to-end encryption protocol to prevent interception during transmission
• Third-party SDK data access is strictly restricted by Android system permission isolation mechanisms
• Internal backend staff access authority is controlled via multi-factor identity verification and strict role-based access limit rules
• Quarterly automated vulnerability scanning is performed on App source code and data transmission channels to eliminate potential security loopholes
• Formal data breach emergency response protocol is established; we will notify all affected users and relevant local regulatory authorities within 72 hours if any unauthorized data exposure incident occurs

No digital storage or internet transmission system can guarantee absolute 100% data security. You shall set a screen lock password for your mobile device to prevent unauthorized third-party access to your local private files.

7. Your Global Privacy Control Rights

All JunkEraseCase users worldwide hold the following controllable privacy rights over data generated from App usage:

• Right to restrict data collection: Turn off anonymous crash log reporting and advertising ID tracking through Android system privacy settings
• Right to erase local data: Clear all App scan cache, filter preferences and temporary file records via system application management page
• Right to withdraw consent: Revoke storage access permissions for JunkEraseCase at any time; all storage scan and cleanup functions will be disabled after permission revocation

CCPA Supplementary Rights for California Users

If you reside in California, United States, you hold supplementary privacy rights regulated under the California Consumer Privacy Act (CCPA). You may request full written disclosure of all data categories collected within the past 12 months and demand permanent deletion of all anonymous aggregated statistical data. JunkEraseCase never sells any user personal identifiable information, so there is no separate opt-out process for data sales. Exercising your CCPA rights will not limit your access to all core free storage cleanup features.

GDPR Rights for EEA, UK & Switzerland Users

Users located in the European Economic Area, United Kingdom and Switzerland enjoy complete data subject rights governed by the General Data Protection Regulation (GDPR). You hold the right to object to data processing based on legitimate interests, and may submit formal written complaints to your local data protection supervisory authority if you believe JunkEraseCase violates GDPR privacy provisions. All cross-border data transmission outside European regions uses European Commission approved Standard Contractual Clauses to maintain equivalent data protection standards.

8. Children’s Privacy Protection (COPPA)

JunkEraseCase Storage Cleaner is designed and rated for users aged 13 and above. We will not intentionally collect personal identifiable data from children under 13 without verifiable written parental consent required by COPPA regulations. If you are a parent or legal guardian and find your minor child has used JunkEraseCase without your formal approval, please contact our dedicated privacy email listed below. We will completely delete all child-related stored feedback and statistical data within 14 business days after verifying your legal identity documentation.

9. Policy Update Notification Rules

We reserve the full right to revise and update this Privacy Policy periodically to adapt to updated Google Play platform policies, global cross-border data protection legislation and JunkEraseCase functional adjustments.

Material policy revisions involving changes of storage data access rules, third-party data sharing scope or user sensitive data processing standards will be notified via in-app pop-up alert prompts at least 14 calendar days before the updated policy officially takes effect. Minor text wording corrections and formatting adjustments will only refresh the “Last Updated” date marked at the top of this page without separate advance user notice.

Your continued use of JunkEraseCase’s storage scan, duplicate media identification and file cleanup functions after the effective date of revised policy terms constitutes full voluntary acceptance of all updated privacy clauses.
