Android System Info — Privacy Policy
Effective date: September 8, 2026
1. App and developer
Android System Info (Android package: com.kkangsuper.deviceinfo) is a free, advertising-supported app provided by SysLab (한석규). This policy applies specifically to Android System Info. For privacy questions or requests, contact kkangsuper@gmail.com.
2. Information used on your device
The app reads Android-accessible device information to show system, CPU, GPU, memory, storage, screen, sensor, battery, hardware and network details. This may include the device model, Android version, local IP address, mobile network operator and network country. Diagnostic values are displayed on your device. The app does not upload a complete inventory of these diagnostic screens to a SysLab server.
Display preferences are stored locally. Android may include app preferences in device backup or transfer according to your device settings. No account, password, contact list, photos or precise GPS location is required to use the app's device-information features.
3. Advertising, analytics, diagnostics and notifications
The app includes Google services that process data off your device. This processing is separate from displaying device information locally.
Google AdMob: The advertising SDK collects and shares IP addresses, advertising or app-set identifiers, ad and app interactions, and diagnostic information. An IP address may be used to estimate approximate location. These data support ad delivery and measurement, analytics, and fraud prevention.
Google Analytics for Firebase: The analytics SDK processes app-instance identifiers, app usage and interaction events, and device and app information to help us understand usage and improve the app. Google may derive approximate geographic information from network information. We do not set a user account identifier in the app.
Firebase Crashlytics: Crash reports can include crash stack traces, application state, app and operating-system versions, device metadata, installation identifiers and diagnostic events. We use these reports to investigate errors and improve stability.
Firebase Cloud Messaging: Firebase installation identifiers and notification registration tokens are used to deliver notifications. The app subscribes to a notification topic based on the mobile network's country code. App version and notification interactions may also be processed by Firebase and Analytics.
If you email support, we receive the email address and information you choose to include so we can respond. Do not send passwords or unrelated sensitive information.
4. Sharing and service providers
Google processes advertising, analytics, crash-reporting and notification data as described above. Advertising-related data may be shared by Google's advertising services for ad delivery, measurement and fraud prevention. Firebase services process operational data to provide services to us. We may disclose information when required by applicable law or to protect users and the service.
Google's policies explain its processing and available controls:
Google Privacy Policy: https://policies.google.com/privacy
Google advertising policies: https://policies.google.com/technologies/ads
Firebase privacy and retention information: https://firebase.google.com/support/privacy
5. Retention and deletion
Local display preferences remain until you clear the app's storage or uninstall it; device backups are managed separately through Android settings. The app does not keep a separate SysLab server history of the diagnostic screens it displays.
Crashlytics retains crash reports and associated identifiers for 90 days before beginning removal from live and backup systems, according to Firebase's published retention policy. Firebase installation data used for messaging is retained until deletion is requested through the service; Firebase states that removal after such a request can take up to 180 days.
Analytics and advertising data are retained under the relevant Google service's retention settings and policies for measurement, security and service operation. Removing the app does not by itself erase data already processed by those services. Google explains its retention practices at https://policies.google.com/technologies/retention.
We retain support correspondence while needed to handle the inquiry and any applicable legal obligations. You may request access, correction or deletion of information associated with you by emailing kkangsuper@gmail.com. We will review the request, identify data we can reasonably associate with it, and use applicable service-provider deletion tools where available. Some records may need to be retained to meet legal obligations. The app does not create user accounts.
6. Your choices
You can reset or delete the advertising ID and manage advertising privacy controls in Android settings, where supported. You can also manage the app's notification permissions, clear its local storage, or uninstall it. These controls do not guarantee deletion of previously processed data. Contact us for help with a privacy or deletion request.
Opening the in-app privacy policy does not require a login, network connection or viewing an advertisement. Links to external policies require an internet connection and are governed by the respective provider's policy.
7. Security and international processing
Google's advertising and Firebase services protect data in transit using encryption. Access to service administration is restricted to authorized operators. Information processed by Google may be processed in countries other than yours, under Google's applicable data-protection arrangements. No transmission or storage method can be guaranteed completely secure.
8. Children and changes
This app is not designed specifically for children under 13. We do not ask children to submit personal information. If you believe a child has provided information to us, contact kkangsuper@gmail.com so we can investigate and take appropriate action.
We may update this policy when the app or its data practices change. The effective date above identifies this revision. The published policy is available at https://sites.google.com/view/pp-deviceinfo/.
