Privacy Policy
Arum Communications Corp. ("we", "us", "our") built the Android System Update app ("the Service") as a free, ad-supported application with an optional one-time in-app purchase. This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use the Service, and the choices you have associated with that information.
By using the Service, you agree to the collection and use of information in accordance with this policy. We will not use or share your information with anyone except as described in this Privacy Policy.
1. Information We Process
1.1 Information processed only on your device
The Service reads system and application information already present on your device in order to display it to you, including:
- Device and OS information (Android version, API level, codename, security patch level, build properties, RAM, storage, display metrics, time zone)
- Google Play services version and Google Play system module (Mainline) versions and license details
- The list of applications installed on your device and their package information (package name, version, and related metadata) for the app-list and app-info features
This information stays on your device. We do not upload your device information, installed-app list, package details, or system module information to any server operated by us. The Service displays this data locally and does not retain it after you leave the relevant screen.
1.2 Permissions used
| Permission | Purpose |
|---|---|
INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE |
Required to load advertising, deliver push notifications, and validate in-app purchases. |
QUERY_ALL_PACKAGES |
Required to enumerate the applications installed on your device so the app can show the installed app list, package details, and update information. This data is read on-device and is not uploaded. |
POST_NOTIFICATIONS (Android 13+) |
Required to show notifications, such as alerts about available app or system updates. |
1.3 Information collected by third-party services
The app uses third-party services that may collect information used to identify you or your device. These services may collect data such as device identifiers (Android Advertising ID), IP address, device model, operating system version, app version, language, country, crash logs, push notification tokens, and aggregated usage events. Please review each provider's privacy policy linked in Section 4 below.
1.4 Purchase information
If you make an in-app purchase (for example, the one-time purchase to remove ads), the transaction is processed by Google Play Billing and managed through RevenueCat. We do not receive or store your full payment instrument (e.g., credit card number). We receive an anonymous app user ID, purchase tokens, entitlement status, and purchase metadata such as country and product ID, in order to grant and validate your purchase.
2. How We Use Information
- To provide the core system-information and app-information features (read locally on your device).
- To deliver advertising, including non-personalized ads where required by law or by your consent choice.
- To send push notifications, such as update-related alerts.
- To measure app performance, diagnose crashes, and improve stability.
- To validate and manage in-app purchases.
- To comply with legal obligations.
3. Legal Basis (EEA/UK Users)
Where the GDPR or UK GDPR applies, we rely on (a) your consent for advertising, analytics, and crash reporting that involve personal data, collected through Google's Consent Management Platform (CMP) shown on first launch; (b) the performance of a contract for purchase processing; and (c) our legitimate interests in operating and securing the Service. You can change your consent at any time from the in-app privacy settings.

5. Advertising and Your Choices
Ads are served by Google AdMob and may use the Android Advertising ID to deliver, measure, and limit the frequency of ads. You can opt out of personalized advertising at any time:
- On Android: open Settings → Google → Ads and toggle "Delete advertising ID" or "Opt out of Ads Personalization".
- For EEA, UK, or Swiss users, you may withdraw or change your advertising consent through the in-app privacy options, which re-displays the Google CMP consent form.
- You may also remove ads entirely through the one-time in-app purchase.
- Learn more: Advertising ID, Google Ad Settings.
6. Push Notifications
The Service uses Firebase Cloud Messaging to send notifications, such as alerts about available app or system updates. To do this, the device is assigned a registration token. You can disable notifications at any time in your device's system notification settings; doing so does not affect the other features of the app.
7. Log Data
When the app crashes or encounters an error, third-party tools (Firebase Crashlytics) may collect diagnostic data including device IP, device model, operating system version, app configuration at the time of the error, and the time and date of the event. This information is used solely to diagnose and resolve issues.
8. Cookies
The Service does not itself use cookies. However, third-party SDKs embedded in the app may use cookie-equivalent identifiers (such as advertising IDs) to provide their services.
9. Data Retention
- System and app information is read on demand and displayed locally; it is not stored on our servers.
- Purchase records are retained by RevenueCat and Google Play Billing for as long as required to maintain your entitlement and for legal/accounting purposes.
- Crash, analytics, and push-notification data are retained according to each provider's standard retention periods.
10. Your Rights
Depending on your jurisdiction (EEA, UK, California, etc.), you may have rights to access, correct, delete, restrict, or port your personal data, and to object to certain processing. To exercise these rights, contact us at the email below. You also have the right to lodge a complaint with your local data protection authority.
11. Security
We take reasonable steps to protect the limited information processed through the Service. However, no method of transmission over the Internet or method of electronic storage is 100% secure, and we cannot guarantee its absolute security.
12. Links to Other Sites
The Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. These external sites are not operated by us. We strongly advise you to review the privacy policy of any site you visit. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.
13. Children's Privacy
The Service is not directed to children under the age of 13, and we do not knowingly collect personally identifiable information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will delete it from our records. If you are a parent or guardian and you believe your child has provided us with personal information, please contact us so that we can take the necessary action.
14. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective date" at the top.
