Privacy Policy

HammerWX desktop application and website
Effective date: August 7, 2026
Operator: Jonathan Douglas (“we”, “us”)

Short version: HammerWX is a desktop weather app. Weather data is loaded from public sources. License and settings stay on your PC. We do not sell your personal data. Crash logs stay on your machine unless you send them to us.

1. Who this covers

This policy applies to the HammerWX Windows desktop application, the website at hammerwx.com (including the download / update pages), and related support we provide by email.

2. Information we collect

A. Stored only on your computer (not uploaded by us)

B. Network activity started by the app

C. Chaser chat (optional)

If you use Chaser chat, the app may exchange messages, a display name, and optional location information with other HammerWX users on the same local network (peer-to-peer / LAN). That traffic is intended for nearby devices; it is not a cloud chat service we host. Other users on the same network who run the feature may see the name and data you share.

D. Website visitors

E. Purchases and support

3. How we use information

We do not sell your personal information.

4. Sharing

We share information only when needed to run the product, for example:

5. Data retention

6. Security

We use reasonable technical and organizational measures appropriate for a small independent software product (including HTTPS for our website and signed installers when published that way). No method of transmission or storage is 100% secure.

7. Children

HammerWX is a professional / enthusiast weather tool and is not directed at children under 13. We do not knowingly collect personal information from children under 13.

8. Your choices

9. International users

The app and website may be used from outside the United States. By using them, you understand that processing may occur in the United States (for example on our hosting infrastructure) and in the regions of the public data providers the app contacts.

10. Microsoft Store

If you install HammerWX from the Microsoft Store, Microsoft’s terms and privacy policy also apply to Store account activity, payments handled by Microsoft, and Store analytics that Microsoft may collect as platform operator. This policy describes our practices for the HammerWX app and hammerwx.com.

11. Changes

We may update this policy from time to time. The “Effective date” at the top will change when we do. Continued use of the app or site after an update means you accept the revised policy.
