Privacy and data use

Privacy Policy

This policy explains what information NetLume processes, why it is needed, where it is stored, and the controls available to you.

Effective August 4, 2026 Applies to iPhone and iPad
Plain-language summary

NetLume does not require an account, does not contain advertising, and does not perform cross-app tracking. Diagnostic reports are stored in the app's local database. Network requests are made when required for app operation or when you run a diagnostic against a target you choose.

1. Scope

This Privacy Policy applies to the NetLume application for iPhone and iPad and the NetLume support website. It does not control the privacy practices of websites or network services that you choose to test or open through the app.

2. Information We Process

Diagnostic inputURLs, domain names, host names, ports, DNS record choices, and HTTP methods that you enter.
Diagnostic resultsResponse status, latency, resolved IP addresses, TCP reachability, HTTPS readiness, local interface information, timestamps, and recommendations.
App preferencesLanguage, appearance, timeout, default request method, history preference, and locally stored access state.
Operational informationApp name and version, an app-specific installation identifier, request time, configuration response status, and limited operational event data needed to operate and protect the app.
Support-site requestsStandard web request information such as IP address, browser type, request time, and requested page may be processed by the hosting provider.

3. How Information Is Used

  • Run the HTTP, DNS, TCP, HTTPS, and local network checks you request.
  • Display results and maintain your local report history.
  • Remember app preferences and locally recognized access state.
  • Deliver operational configuration, prevent misuse, investigate failures, and maintain service reliability and security.
  • Respond to support and privacy inquiries.

4. Storage and Transmission

On-device storage

Completed diagnostic reports are stored in a SwiftData database inside the app's sandbox. Preferences and access state are stored using system preference storage. An app-specific installation identifier may be stored in Keychain. Cached operational configuration may be stored in the app's cache directory.

Network transmission

When you run a diagnostic, the app connects to the URL, host, DNS service, or port you selected. Those destinations and intervening network providers receive the technical information normally required to complete a network request.

For app operation, NetLume may request configuration using the app name and an app-specific installation identifier. If an operational event endpoint is enabled, a limited event may include the app channel, bundle identifier, submitted verification value, and installation identifier. This data is used for app functionality, security, and reliability, not for advertising.

5. Sharing and Third Parties

We do not sell personal information. We do not use third-party advertising SDKs, social login SDKs, or cross-app advertising trackers.

Information may be processed by infrastructure providers that host operational services or support pages, by network destinations you choose to test, or when required to comply with law, protect users, or defend legal rights.

6. Retention

Local reports remain until you delete an individual report, clear report history, or uninstall the app. Preferences, access state, cached configuration, and the installation identifier remain until removed by the app, operating system, or uninstall process.

Operational server records are retained only for as long as reasonably needed for functionality, security, troubleshooting, and legal obligations.

7. Your Choices

  • Turn off saving scan history in Settings.
  • Delete individual reports or clear all report history.
  • Avoid running a diagnostic against any destination you do not want to contact.
  • Delete NetLume to remove data stored in the app container. Some Keychain items may be managed separately by the operating system.
  • Contact us to ask a privacy question or request help concerning operational data.

8. Security

We use platform storage protections and reasonable administrative and technical safeguards appropriate to the nature of the information. No storage or transmission method can be guaranteed to be completely secure.

9. Children's Privacy

NetLume is a general-purpose network utility and is not directed to children under 13. We do not knowingly collect personal information from children under 13.

10. Changes to This Policy

We may update this policy when NetLume's functionality or legal obligations change. The effective date at the top of this page identifies the current version.
