# Privacy Policy

Last updated: 25 OCT 2025

## Ham Radio Net Control

**Developer:** K4HEF

**App Name:** Ham Radio Net Control

## Overview

Ham Radio Net Control ("the App") is a standalone iOS application designed for amateur radio operators to manage net operations, track check-ins, and generate reports. This privacy policy explains how we handle information related to your use of the App.

## Data Collection and Storage

### No Data Collection

Ham Radio Net Control is a **fully standalone application** that does not collect, transmit, or store any personal information outside of your device. The App does not have any internet-connected backend services, analytics, or third-party data collection mechanisms.

### Local Data Storage

All data created using the App (including but not limited to net operations, check-ins, notes, and reports) is stored exclusively on your iOS device using local storage mechanisms:

- **Core Data**: For net operations and check-in data

- **UserDefaults**: For application settings and preferences

- **Keychain**: For secure storage of credentials (QRZ API credentials only, if configured)

- **File System**: For temporary file storage (PDF reports)

### Third-Party Services

If you choose to configure QRZ.com API credentials in the App settings, the App will communicate directly with QRZ.com servers to retrieve amateur radio license database information. This communication occurs only when you initiate a callsign lookup, and no data is transmitted from your device except the callsign you are searching for.

## Data Security

All data stored by the App is encrypted using iOS's built-in security mechanisms:

- Keychain data is encrypted using iOS Keychain Services

- Core Data uses SQLite with iOS encryption at rest

- UserDefaults data is stored in the app's protected container

## Your Rights

Since we do not collect or process any personal data:

- Your data remains on your device under your sole control

- You can delete the App at any time to remove all associated data

- The App does not have user accounts or registration requirements

## Children's Privacy

The App is not directed to children under the age of 13. We do not knowingly collect information from children. The App does not have any data collection mechanisms, making this concern moot, but we include this for completeness.

## Changes to This Privacy Policy

We may update this privacy policy from time to time. You are advised to review this page periodically for any changes. Changes are effective immediately after being posted.

## Consent

By using the App, you consent to this privacy policy. If you do not agree with the terms of this policy, please do not use the App.

**Note:** This App operates entirely offline with local data storage. No data is transmitted from your device except when you explicitly choose to use the QRZ.com lookup feature, in which case only the callsign you are searching for is sent to QRZ.com's servers.
