K-Cleaner Privacy Policy

1. Developer & App Overview

This Privacy Policy explains how K-Cleaner ("the app"), developed by Deepak Kumar, handles information when you use the app on your Android device.

K-Cleaner is an Android storage maintenance and file management utility. It helps you review storage utilization, find potential junk files, detect duplicate media, and organize files on your device.

This policy covers both data handled directly by the app and data collected by the third-party SDKs it includes. You are encouraged to review the linked third-party policies for complete details on their practices. For terms governing acceptable usage and liability, please review our User Agreement.

2. On-Device File Processing

K-Cleaner's file scanning, duplicate detection, and cleanup features are designed to operate locally on your device:

• Local Scanning: File indexing, size calculations, folder grouping, and duplicate detection (via content hashing) are performed on your device. The app's own code does not transmit your personal files to any server.
• User-Confirmed Deletion: Scanned junk, media, duplicates, and other shared-storage items are not deleted automatically. Those deletions require your explicit selection and confirmation (and may also require an Android system delete-consent dialog when All files access is not granted). Separately, if you tap the optional Quick Boost notification action, the app may delete only K-Cleaner's own temporary cache files under its app-specific cache directories without an additional in-app confirmation dialog.
• Platform Boundaries: Under Android's security model, K-Cleaner cannot access or clear other apps' private internal caches or data directories (such as /data/data/ or protected areas under /Android/data/). Only K-Cleaner's own cache can be cleared directly.

Note: While the app's own code does not upload your files, third-party SDKs included in the app may independently collect device and interaction information as described in the Advertising and Third-Party Services sections below.

3. Android Permissions

K-Cleaner requests the following Android permissions to provide its features:

Permissions not requested by app code: K-Cleaner does not request access to your camera, microphone, GPS/precise location sensors, contacts, call logs, SMS, calendar, or biometric data. The app does not use QUERY_ALL_PACKAGES.

Permissions merged from advertising SDKs: The Google Mobile Ads SDK may add advertising-related permissions to the installed app (for example com.google.android.gms.permission.AD_ID and Android Advertising Services permissions). These support advertising identifiers and Privacy Sandbox features described in the Advertising section. They are not used by K-Cleaner's file-cleaning features.

4. Usage Access & Device Insights

When you grant the optional Usage Access permission, K-Cleaner queries standard Android platform APIs on your device:

• Last-Used Times: Queries UsageStatsManager to show when apps were last opened.
• Data Usage: Queries NetworkStatsManager to display per-app Wi-Fi and mobile data consumption. No network packets, browsing history, or message content is intercepted or recorded.
• Process Information & Quick Boost: Lists processes using UsageStatsManager and/or ActivityManager. Per-app memory figures shown in Process Explorer are estimates derived from device memory-class heuristics, not precise per-process memory measurements. Quick Boost terminates eligible background processes using Android's standard killBackgroundProcesses() and removes only K-Cleaner's own temporary cache files (for example .tmp, .temp, or cache_* under the app's cache directories). Reported RAM reclaim is based on the measured change in available system memory after the operation; if no positive change can be measured, the app reports that the change was too small to measure rather than inventing a value.

This usage and process information is queried and displayed locally. K-Cleaner's own application code does not transmit usage histories, process lists, or file inventories over the network.

5. Notifications & Reminders

K-Cleaner can send optional cleaning reminder notifications:

• Daily Limit: At most two proactive reminder notifications per local calendar day.
• Spacing: Proactive reminders are spaced at least four hours apart.
• Quiet Hours: No proactive notifications between 10:00 PM and 7:00 AM local time.
• Quick Boost from Notification: Tapping the Quick Boost action in a notification runs the cleanup without showing an advertisement. User-initiated Quick Boost updates do not count toward the daily proactive limit.
• Attribution: Notifications are labeled as coming from K-Cleaner and are not designed to imitate system security or OS alerts.
• User Control: You can enable or disable reminders in K-Cleaner's Settings screen or via Android system settings for the app at any time. On Android 13 and newer, posting also requires the runtime POST_NOTIFICATIONS permission.

6. Advertising (Google AdMob)

K-Cleaner is ad-supported and does not charge subscription fees. The app includes the Google Mobile Ads SDK (AdMob) version 23.6.0 (play-services-ads).

According to Google's Play data disclosure documentation for the Google Mobile Ads SDK (reviewed against the published disclosure for recent SDK releases; this app currently depends on play-services-ads 23.6.0), AdMob automatically collects and may share the following categories of information for advertising, analytics, and fraud prevention:

This data is collected and transmitted by the Google Mobile Ads SDK and is subject to Google's own retention and processing practices. Google states that user data collected by the Google Mobile Ads SDK is encrypted in transit using TLS. Ad delivery generally requires this SDK activity and cannot be selectively disabled within the app while ads remain enabled, though you can manage advertising preferences as described in the User Controls section.

The AdMob SDK also transitively includes the play-services-measurement-sdk-api library (used internally by Google Ads) and the ads-adservices library (for Android Privacy Sandbox support). These components may process additional signals as part of Google's advertising infrastructure.

For full details on Google's data practices, see:

• Google Privacy Policy
• How Google Uses Information from Sites or Apps That Use Our Services

7. Consent Management (Google UMP)

K-Cleaner includes the Google User Messaging Platform (UMP) SDK version 3.1.0 for managing advertising consent where required by applicable law (such as in the European Economic Area under the GDPR, or in certain US states).

• Consent Dialog: Where legally required, a consent form is presented before personalized advertisements are served.
• Ad Initialization Gating: The app checks consent status before requesting ads. If consent has not been gathered or is not required for your region, the SDK determines the appropriate ad behavior.
• Updating Consent: The current version of K-Cleaner does not provide a dedicated in-app button to re-open the consent form after initial presentation. To reset your consent preferences, you can clear the app's storage via Android Settings > Apps > K-Cleaner > Storage > Clear Data, which will cause the consent dialog to appear again on next launch. You can also manage ad personalization at the device level via Android Settings > Google > Ads.

8. Third-Party Services & Data Sharing

K-Cleaner does not sell or rent your personal information. The app includes the following third-party services:

The AdMob SDK includes transitive dependencies (play-services-measurement-sdk-api, play-services-appset, ads-adservices) that are part of Google's advertising infrastructure. These components may collect or process data under Google's policies.

Based on the current dependency tree, the app does not include Firebase Analytics, Crashlytics, Facebook/Meta SDKs, or other commercial analytics or tracking libraries. If this changes in future updates, this policy will be revised accordingly.

9. Network Transmissions

K-Cleaner's own application code does not operate backend servers or transmit your files, file lists, or scan results over the network.

Network communication from the app includes:

1. Ad requests and impression reporting through the Google Mobile Ads SDK.
2. Consent verification through the Google UMP SDK.
3. Any additional network activity initiated by Google's advertising infrastructure and its transitive dependencies.

According to Google's published Mobile Ads data disclosure, user data collected by the Google Mobile Ads SDK is encrypted in transit using the Transport Layer Security (TLS) protocol. K-Cleaner does not implement custom cleartext networking for its own features.

10. Data Retention & User Controls

K-Cleaner's own local data consists of app preferences stored in Android's private SharedPreferences (theme, language, notification toggle, onboarding status, notification rate-limiter counters). You can manage your data in the following ways:

• Revoking Permissions: Revoke any granted permission at any time via Android Settings > Apps > K-Cleaner > Permissions.
• Clearing App Data: Clear all local preferences and cached data via Android Settings > Apps > K-Cleaner > Storage > Clear Data. This also resets your advertising consent status.
• Uninstalling: Uninstalling K-Cleaner removes all locally stored preferences and cache files from your device.
• Advertising ID: You can reset or delete your device's Google Advertising ID via Android Settings > Google > Ads. This does not affect data already collected by Google.
• Ad Personalization: You can opt out of ad personalization via your Android device settings. Note that opting out does not prevent ads from being shown; it affects whether ads are personalized.

Data collected and retained by third-party services (Google AdMob, UMP) is subject to their own retention and deletion practices. Refer to Google's Privacy Policy for details.

11. Children's Privacy

K-Cleaner is a general-purpose storage utility. It is not designed for or directed at children. The app has not been configured to serve child-directed ads through AdMob, and the app's advertising consent flow does not include age-gating.

If you are a parent or guardian and have concerns about information that may have been collected through the app's advertising services, please contact us at the address below.

12. Security

K-Cleaner takes the following measures to protect the app's integrity:

• The app's file processing is designed to operate locally, reducing the surface area for remote data exposure from the app's own code.
• Internal components such as broadcast receivers and the FileProvider are configured with android:exported="false" to prevent unauthorized access from other apps.
• Android's application sandbox isolates K-Cleaner's private storage from other installed applications.
• According to Google's documentation, Google Mobile Ads SDK user-data transmissions use TLS in transit.

No method of electronic storage or transmission is completely secure, and this policy does not guarantee absolute security. We encourage you to keep your device's operating system updated.

13. Changes & Contact

This Privacy Policy may be updated when app features, included SDKs, or applicable requirements change. The "Last Updated" date at the top of this page will be revised when changes are published. We encourage you to review this page periodically.
