Privacy Policy

Effective Date: February 11, 2026 Last Updated: May 2, 2026

Hamtrax ("we," "us," or "our") respects your privacy. This Privacy Policy explains how we collect, use, store, and share information when you use the Hamtrax application, website, and related services (the "Service").

1. Information We Collect​

Information You Provide​

  • Account information: Email address, name, callsign, country, and license class.
  • Profile information: Display name, nickname, and profile photo.
  • QSO logs: Contact records you create or import, including callsigns, frequencies, modes, dates, times, and notes.
  • Location data: Grid square, coordinates, or city — depending on the location mode you choose (callsign lookup, device GPS, or manual entry).
  • User-generated content: Photos, livestream URLs, folder cover images, station equipment images, and feedback submissions.
  • Billing information: If you subscribe to a paid plan, payment is processed by Stripe (web and Android) or by Apple via the App Store using RevenueCat (iOS). We do not store your credit card number or full payment details — these processors handle them directly. We store only your subscription status, plan type, and the customer ID issued by the relevant processor.
  • Station equipment: Rig and antenna profiles, including names, descriptions, and photos you upload.

Information Collected Automatically​

  • Device information: Browser type, operating system, and device identifiers.
  • Usage data: Pages visited, features used, and interaction patterns within the Service. This includes tutorial and walkthrough completion state (so we can avoid re-running first-run flows you've already seen).
  • Analytics data: We use Google Firebase Analytics (GA4) to collect anonymized usage metrics such as page views, sign-up completions, and login events. This data helps us understand how the Service is used and where to improve. Analytics data is processed according to Google's privacy policies and does not personally identify you.
  • Session replay: We use Microsoft Clarity to record session replays of how the Service is used — including page interactions such as clicks, scrolling, and mouse movement — so we can identify usability issues and improve the Service. Clarity may also collect device and browser information. Recordings are processed by Microsoft and are subject to Microsoft's Privacy Statement. We do not use session replays to identify individual users.
  • Authentication data: OAuth tokens and session information from third-party sign-in providers (Google, Apple).

Information from Third Parties​

  • Callsign lookups: We query external databases (HamQTH, QRZCQ, QRZ Digital, and the FCC ULS amateur database) to retrieve publicly available callsign registration data such as name, address, grid square, and license class.
  • Activity data: We aggregate data from public amateur radio services (POTA and the FCC amateur radio database) to power activity discovery features.
  • Location imagery: We use Flickr's public API to source geo-tagged nature photography for park and location displays.

2. How We Use Your Information​

We use collected information to:

  • Provide, operate, and improve the Service.
  • Create and manage your account.
  • Display your profile and QSO statistics to other users (based on your privacy settings).
  • Power location-based features such as distance calculations and map displays.
  • Resolve callsign data and derive default settings (band plan, license privileges).
  • Send service-related communications (account verification, password resets, and welcome messages upon sign-up).
  • Detect and prevent abuse, fraud, or violations of our Terms of Service.

3. How We Share Your Information​

We do not sell your personal information.

We may share information in the following circumstances:

  • Public profile data: Your callsign, display name, and profile photo may be visible to other Hamtrax users depending on your settings.
  • Service providers: We use third-party services (Firebase/Google Cloud for hosting and storage; Microsoft Clarity for session replay analytics) to host, store, and process data on our behalf. These providers are bound by their own privacy commitments.
  • Payment processors: If you subscribe to a paid plan on the web or Android, billing is handled by Stripe, Inc. and Stripe receives the payment information you provide during checkout; Stripe's use of your data is governed by Stripe's Privacy Policy. If you subscribe through the iOS app, billing is handled by Apple via the App Store and entitlements are mediated by RevenueCat, Inc.; their use of your data is governed by Apple's Privacy Policy and RevenueCat's Privacy Policy.
  • Legal requirements: We may disclose information if required by law, regulation, or legal process.
  • Safety: We may share information to protect the rights, safety, or property of Hamtrax, our users, or the public.

4. Data Storage and Security​

  • Your data is stored using Google Firebase (Firestore, Firebase Authentication, and Firebase Storage for user-uploaded media) with encryption in transit and at rest.
  • Certain data is cached locally on your device (IndexedDB) for offline access and performance.
  • We implement reasonable technical and organizational measures to protect your information. However, no system is completely secure, and we cannot guarantee absolute security.

5. Your Location Data​

Location is central to many ham radio activities. You control how Hamtrax determines your location:

  • Callsign mode: Location is derived from your callsign registration address (publicly available data).
  • Device mode: Location is obtained from your device's GPS with your permission. We do not track your location in the background.
  • Manual mode: You enter a grid square, coordinates, or city of your choosing.

You can change your location mode at any time in Settings. Location data is used for distance calculations, propagation estimates, and map features.

6. Data Retention​

  • We retain your account data for as long as your account is active.
  • Practice contacts generated by the in-app guided walkthrough are temporary and are deleted automatically by a server-side cleanup task -- they are not retained as part of your logbook.
  • If you delete your account, your authentication credentials are removed. QSO logs and associated data may be retained in anonymized form for aggregate statistics. Account deletion removes your login credentials; to export your data beforehand, use the ADIF export feature.

7. Your Rights​

Depending on your jurisdiction, you may have the right to:

  • Access the personal information we hold about you.
  • Correct inaccurate information in your profile.
  • Delete your account and associated personal data.
  • Export your QSO logs and data.
  • Object to certain processing of your information.

To exercise these rights, contact us at info@hamtrax.com or use the account management features in Settings.

8. Children's Privacy​

The Service is not intended for children under 13. We do not knowingly collect personal information from children under 13. If we learn that we have collected information from a child under 13, we will delete it promptly.

The Service may contain links to third-party websites or integrate with external services (QRZ, HamQTH, POTA, etc.). We are not responsible for the privacy practices of these third parties. We encourage you to review their privacy policies.

10. Changes to This Policy​

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy with a new "Last Updated" date. Continued use of the Service after changes constitutes acceptance.
