Effective Date: July 15, 2026

1. Information We Collect

None. WillisSDR does not collect any personal information, usage statistics, crash reports, or analytics of any kind. The application has no backend server of ours and does not phone home.

2. Your Radio and Your Local Network

WillisSDR’s core function is to discover and control a FlexRadio device on your network using FlexRadio’s own network protocol (VITA-49). This communication happens directly between the application and your radio:

• Radio discovery and control traffic stays on your local network.
• Spectrum, metering, and audio data flow between your radio and your computer.
• None of this traffic is routed to, copied to, or stored on any server we operate.
• WillisSDR does not require an internet connection to control your radio.

3. Local Data Processing

WillisSDR reads and writes its data on your local file system. Specifically:

• Radio profiles and presets are stored locally on your device.
• Application preferences are stored locally on your device.
• No data is uploaded to, processed by, or stored on any server we operate.

4. Telemetry and Analytics

WillisSDR does not include any telemetry, analytics, or crash-reporting frameworks. We do not track how you use the application, which features you access, how often you use it, or any other behavioral data.

5. Tracking and Advertising

WillisSDR does not use cookies, tracking pixels, advertising identifiers, fingerprinting, or any other tracking technologies. We do not display advertisements and we do not participate in any advertising networks.

6. Purchases & Payment Processing

If you purchase WillisSDR through the Apple App Store, Microsoft Store, or any other distribution platform, that platform may collect transaction and account information as part of the purchase process. This data is collected and managed by the respective platform, not by us. Please refer to the applicable platform's privacy policy for details:

• Apple Privacy Policy
• Microsoft Privacy Statement

We do not receive, store, or have access to your payment information, Apple ID, Microsoft account, or any other account credentials.

Direct purchases of the Linux version. The Linux edition of WillisSDR is sold directly from our own online store rather than through a platform app store. When you buy it this way, a few commerce partners are involved and a limited amount of information is handled off your device:

• Merchant of Record — Lemon Squeezy. Our store is operated by Lemon Squeezy, which acts as the Merchant of Record for the sale. To meet tax and Know-Your-Customer (KYC) requirements, Lemon Squeezy collects your name, billing address, and email address during checkout.
• Payment processing — Stripe. The financial transaction is processed by Stripe, which handles your payment-card details. We never see or store your card information.
• What we keep. From this process Lacy Digital Labs receives and retains only your email address. We use it solely to reach you about the app you purchased — for example, to let you know when a new version, patch, or feature is available. We do not use it for marketing, and we will never sell or rent it to any third party.

You can ask us to delete your email address at any time (see “Your Data Rights” below). For how these partners handle your information, see the Lemon Squeezy Privacy Policy and the Stripe Privacy Policy.

7. Third-Party Services

WillisSDR does not integrate with, send data to, or receive data from any third-party cloud services operated by us. The only network communication WillisSDR performs is the direct, local control of your own radio described in Section 2. WillisSDR is self-contained and does not depend on any online service to function.

8. Children's Privacy

Because WillisSDR does not collect any data from any user, it does not knowingly or unknowingly collect information from children under the age of 13 (or any other age).

9. Your Data Rights

Because WillisSDR does not collect, process, or store any personal data on our systems, there is no personal data of yours for us to access, correct, delete, or transfer. Your profiles and settings exist only on your device under your full control. You can export or delete them at any time.

The one piece of personal data we may hold is the email address collected when you buy the Linux version directly from our store (see “Purchases & Payment Processing” above). You may ask us to access or delete that email address at any time by contacting our support center; we will delete it promptly, after which you will no longer receive our update notices for the app.

10. Data Security

Since WillisSDR does not collect or transmit data to us, there is no risk of your data being intercepted, breached, or exposed through our systems. Your local files are protected by your operating system's built-in security mechanisms and any encryption you apply at the device level.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, regulatory, or operational reasons. Any changes will be posted on this page with an updated effective date.
