Privacy Policy

How SmartClean handles permissions, local cleaning data, analytics, advertising, diagnostics, and network measurement services.

Last updated: August 10, 2026

Plain-language summary. SmartClean is a free, ad-supported Android cleaner and phone utility app. We do not offer subscriptions in the current version. Cleaner features are designed to run locally on your device. We do not upload your personal files, photos, videos, WhatsApp messages, contacts, chat names, notification text, browsing history, or private document contents to our servers. We use advertising, analytics, diagnostics, consent, support, and network measurement services described below, including AppLovin and its mediated advertising networks, Firebase, Amplitude, Measurement Lab (M-Lab), and Cloudflare.

2. Scope of this policy

This policy explains how SmartClean accesses, collects, uses, shares, retains, and deletes information. It covers app features, Android permissions, advertising, analytics, diagnostics, support messages, deletion requests, and third-party services. It should be read together with any in-app permission screens, prominent disclosures, consent prompts, and the Google Play Data safety section for the app.

SmartClean does not require an account to use core cleaner features. We do not currently sell subscriptions, premium memberships, or recurring paid plans. The current monetization model is advertising.

3. Core privacy commitments

  • We do not upload your personal files, photos, videos, audio, documents, WhatsApp messages, WhatsApp contacts, chat names, notification contents, browsing history, or private content to our servers.
  • We do not sell your personal files or private content.
  • We do not delete files, uninstall apps, or clean WhatsApp media without a user action and confirmation where required by Android.
  • We request Android permissions only when a feature needs them and we explain why sensitive permissions are requested.
  • Analytics events are designed to avoid file names, file paths, message contents, notification text, contact names, phone numbers, raw IP addresses, precise GPS location, IMEI, serial numbers, Android ID, MAC address, and full installed-app lists.
  • When a third-party SDK or measurement service processes data, we disclose it in this policy and link to the provider’s privacy information where practical.

4. Data processed by app features

5. Android permissions and sensitive access

Depending on the version of the app, Android version, and the features you use, SmartClean may request the following permissions or special access settings. You can grant, deny, or revoke permissions in Android settings. If a permission is denied, the related feature may not work or may offer a limited fallback.

  • Photo, video, audio, media, storage, or folder access — used to scan and clean files you ask SmartClean to review. On Android versions that support partial media access, the app is designed to respect the photos and videos you selected.
  • All files access — used only when necessary for core cleaner functionality that cannot work properly with MediaStore, Android Photo Picker, or Storage Access Framework alone. If requested, it is used to scan user-accessible shared storage for cleanable files and is not used to upload your personal file contents.
  • Storage Access Framework folder picker — may be used as a more limited fallback where you select a folder, such as a WhatsApp Media folder.
  • Internet and network state — used to load ads, analytics, consent messages, diagnostics, support pages, and run Network Speed Test.
  • Usage Access — used only if you grant it in Android settings, to show recently active or rarely used apps for App Manager and Uninstall Apps.
  • Notification Access — used only if you grant it in Android settings, to clear or hide notifications from apps you select. Notification text is not uploaded to our servers.
  • Post Notifications — used to send reminders if you enable them.
  • Request delete packages — used to open Android’s system uninstall confirmation for apps you select. SmartClean does not perform silent uninstall.
  • Vibration and audio settings — used for Speaker Cleaner sound and vibration effects.
  • Accessibility access — not required for the core cleaner features described in this policy. If an optional guided accessibility mode is ever offered, it must have a separate in-app disclosure and consent screen, explain exactly what it does, and must not be used to collect screen contents or private text.

6. In-app disclosures and user control

For sensitive features, SmartClean is designed to show an in-app explanation before requesting access. Examples include broad storage access, folder access for WhatsApp media, usage access, notification access, network speed testing, and any optional accessibility mode. The disclosure explains what data is accessed, why it is needed, what is not collected, and how the user can decline or revoke access.

Cleaner actions are user-controlled. The app is designed to show results before deletion and ask for confirmation before deleting selected files, photos, WhatsApp media, or apps. Android may also show system confirmation screens for media deletion and app uninstall actions.

7. WhatsApp Cleaner details

The WhatsApp Cleaner feature scans locally stored WhatsApp media and related files on your device after you grant storage or folder access. It can delete selected files to free up storage. We do not upload your WhatsApp files, messages, contacts, chat names, file names, file paths, database names, backup files, or file contents to our servers.

SmartClean does not delete WhatsApp chat databases, backups, msgstore files, .crypt files, WhatsApp account data, or internal WhatsApp app data. Deleting selected WhatsApp media may cause those media files to stop opening inside WhatsApp chats. The app is designed to tell you this before deletion.

SmartClean is not affiliated with, endorsed by, or sponsored by WhatsApp LLC, Meta Platforms, Inc., or any of their affiliates. WhatsApp names and logos belong to their respective owners.

8. Network Speed Test details

Network Speed Test runs only after you start it. The app connects to third-party network measurement services, primarily Measurement Lab (M-Lab) NDT7 and, if needed, Cloudflare Speed Test endpoints. A speed test can use significant data, especially on mobile data, so the app may show a mobile-data warning before the test starts.

When you use M-Lab, M-Lab may collect technical measurement data and connection metadata related to the test, including the IP address used for the test, test date/time, server information, network information, and performance metrics. M-Lab may retain and publish measurement data, including IP addresses, under its own privacy policy and data policy. We do not control M-Lab’s records and may not be able to delete M-Lab test data for you.

When you use Cloudflare Speed Test endpoints, Cloudflare may receive your IP address, estimate your location at country/city level, identify your network or Autonomous System Number (ASN), process test timing and performance metrics, truncate IP addresses for speed-test processing as described by Cloudflare, and share anonymized measurement information with measurement partners under Cloudflare’s own policies. We do not use Network Speed Test to access your browsing history, personal files, messages, photos, precise GPS location, contacts, or private content.

Our analytics for this feature are designed to use technical aggregates, such as provider used, fallback status, connection type, download/upload Mbps, bytes transferred, duration, error type, and whether mobile data was cancelled. We do not intentionally send raw IP address, hostnames, exact device location, URLs you visit, browsing history, or private content to Amplitude, Firebase, or our own analytics.

9. Device Status details

Device Status collects device information locally to display technical details such as Android version, memory, storage, battery, CPU, and screen information. This feature is designed to work without requesting runtime permissions. We do not use Device Status to collect IMEI, IMSI, phone number, contacts, messages, files, user accounts, serial number, Android ID, MAC address, SIM data, operator subscriber data, or exact hardware identifiers that are not needed for the feature.

Analytics for Device Status may include only aggregated technical events such as screen opened, operation status, duration, and unavailable fields count. If product decisions require sending Android version or device model in analytics, that must be reflected in the app’s data audit and Google Play Data safety disclosure.

10. Analytics, diagnostics, advertising, and consent

SmartClean is free and monetized through advertising. We use the AppLovin SDK and AppLovin MAX mediation platform to show ads. AppLovin may make ads available from its own services and from mediated advertising networks. We may also use consent management, Firebase services, Google Analytics for Firebase, Firebase Crashlytics, Firebase Performance Monitoring, Firebase Remote Config, Amplitude, Google Play services, hosting, email, and similar providers to operate, secure, analyze, improve, and monetize the app.

Depending on your device settings, consent choices, region, SDK versions, and app configuration, these providers may process data such as:

  • IP address processed by service providers, approximate region, advertising ID where available and permitted, app instance ID, Firebase installation ID, device or other identifiers, and consent signals.
  • App interactions, screen or feature usage, ad impressions, ad clicks, ad request data, session information, attribution data, and user product interactions.
  • Crash logs, diagnostics, performance data, app launch time, hang rate, energy usage, SDK performance, device type, operating system version, app version, language, network information, and installation source.

The AppLovin SDK and AppLovin's mediated advertising networks may collect or receive the advertising ID, IP address, device or other identifiers, ad request and interaction data, diagnostic information, and consent signals. This information is transmitted to AppLovin and, where an ad is served through mediation, to the relevant advertising network so that ads can be delivered, measured, personalized where permitted, frequency-capped, and protected against fraud. Firebase data collection depends on the Firebase SDKs used and app configuration. Amplitude may process event data; we do not add raw IP addresses to Amplitude event properties, and where supported by SDK or account settings, we configure Amplitude to disable IP tracking or drop IP addresses after ingestion.

We configure analytics events to avoid personal file names, file paths, document contents, message contents, contact names, phone numbers, raw IP addresses, precise GPS location, IMEI, serial number, Android ID, MAC address, full installed-app lists, and notification text.

In the European Economic Area, United Kingdom, Switzerland, and other regions where required, the app may show a consent message for personalized ads, measurement, and related data processing. You can manage ad personalization through Android advertising settings, Google settings, and any consent controls shown in the app. Non-personalized or limited ads may still require certain technical data for delivery, security, frequency capping, and fraud prevention.

11. Google Play Data safety alignment

The Google Play Data safety section for SmartClean must match the actual app build, SDK versions, permissions, and configuration. Depending on the release, Data safety may need to disclose data categories such as app activity, app interactions, diagnostics, crash logs, performance data, device or other identifiers, approximate location derived from IP, advertising data, and user-provided contact/support information. It must also account for data collected or shared by third-party SDKs, even if the data is sent directly to those SDK providers and not to our own servers.

This policy is intended to be consistent with the Data safety section, but the Play Console form must be reviewed whenever permissions, SDKs, analytics events, ad settings, consent settings, or app features change.

12. Third-party services

Third-party services may process information under their own privacy policies and terms. Relevant providers may include:

  • AppLovin and AppLovin MAX mediation, including mediated advertising networks
  • Google services, including Google Play services and Google Analytics for Firebase
  • Firebase privacy and security information
  • Amplitude
  • Measurement Lab (M-Lab)
  • Cloudflare

13. How we use information

We use information to provide app features, show results to you, remember settings, maintain safety and security, fix bugs, measure performance, prevent fraud and abuse, show ads, manage consent, comply with legal obligations, respond to support and deletion requests, and improve the app.

14. Sharing of information

We may share limited information with service providers that help us operate analytics, diagnostics, advertising, consent management, hosting, email, support, and speed testing. We may also disclose information if required by law, to protect rights and safety, or in connection with a merger, acquisition, financing, reorganization, or sale of assets.

We do not sell your personal files, WhatsApp files, photos, videos, documents, notification text, contacts, or private content. Some advertising or analytics processing may be considered a "sale", "sharing", or targeted advertising under certain privacy laws. Where required, we provide applicable opt-out or consent controls.

15. Data retention

CategoryTypical retention
Local cleaner scan data and settingsStored on your device until you rescan, clear app data, or uninstall the app. Some temporary local scan results may be deleted automatically after the operation or after they are no longer needed.
Local files, photos, WhatsApp media, and notificationsWe do not store these on our servers. They remain on your device unless you delete selected items.
Support and contact messagesUsually retained for up to 24 months after the last interaction, unless a longer period is needed for security, legal, tax, abuse-prevention, or dispute reasons.
Deletion and privacy request recordsUsually retained for up to 36 months so we can document request handling and comply with legal obligations.
Analytics, diagnostics, ad, and consent dataRetained according to provider settings and our configuration, generally no longer than needed for analytics, diagnostics, security, fraud prevention, legal compliance, and service improvement. Event-level analytics is intended to be configured to a limited retention period where available. Aggregated or de-identified data may be retained longer.
M-Lab and Cloudflare speed test dataHandled by those providers under their own policies. M-Lab may retain and publish measurement data; Cloudflare processes speed test data under its own privacy terms. We do not control their independent retention rules.

16. Your choices and rights

  • Revoke Android permissions at any time in device settings.
  • Clear local app data or uninstall the app to remove locally stored settings and scan caches.
  • Reset or delete the Android advertising ID where Android provides that control.
  • Manage personalized ads through Android advertising settings, Google ad settings, and in-app consent choices where available.
  • Use our Delete Data page to request deletion of data associated with SmartClean where we can reasonably identify it.
  • Depending on your location, you may have rights to access, correct, delete, restrict, object, withdraw consent, opt out of sale/share or targeted advertising, data portability, or appeal a privacy decision.

To protect privacy and security, we may need to verify your request. Because SmartClean does not require accounts, some analytics or third-party data may not be reasonably identifiable unless you provide an identifier available in the app or device settings. We cannot delete data that we do not control, such as independent records held by M-Lab, Cloudflare, Google, or Amplitude, but we will explain available options where possible.

17. Children’s privacy

SmartClean is not directed to children under 13 or the minimum age required by local law. We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us and we will take appropriate steps. The app is not intended to be listed as primarily directed to children unless its design, ads, SDKs, and privacy controls are changed to meet all applicable child-safety and family policies.

18. Security

We use reasonable technical and organizational measures designed to protect information. Data transmitted by major SDK providers is typically protected in transit, and we limit analytics events to technical or aggregate data where possible. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

19. International processing

SmartClean, our website, and third-party providers may process information in countries other than where you live. Where required, we rely on appropriate legal mechanisms for cross-border transfers.

20. Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last updated" date and, where appropriate, provide additional notice in the app or on this website. Please review this policy periodically, especially after app updates that add new features, permissions, SDKs, or data practices.
