Privacy

qsonaut has no account, no server holding your log and no ads. Your contacts stay on your devices and nowhere else, unless you send them yourself.

Who is responsible

Marcin Stryjczak, SQ5SJW, the author of qsonaut. Contact: [email protected].

What stays on your device

• Your log, setups, settings and backups — in the program's local database and in the folder you choose.
• Service passwords and the log's keys — in the system keychain (macOS, Windows, Linux, iOS) or Android Keystore.
• Rig and rotator control through Hamlib works within your local network.

What leaves it, and where to

• Synchronisation between your devices. On a local network devices connect directly. Over the Internet, when you turn it on, the connection may go through an iroh relay (by default n0's public relay, or your own set in the program). Data is encrypted between your devices; the relay sees only IP addresses and encrypted traffic.
• QRZ.com and HamQTH. Only when you connect your own account in the program: the callsign you type and your sign-in go to the chosen service, which returns the station's details.
• LoTW, eQSL.cc, QRZ.com logbook. On the computer only, and only when you set them up: the contacts you send yourself, and downloading confirmations.
• New versions (computer only). Once a day the program asks api.qsonaut.app whether a new version is out, giving its version and operating system. The server counts the questions by version, system and country (Cloudflare derives the country from the IP address; the address is not stored). Turn it off in Settings → New versions. The phone app does not ask.

External services (QRZ.com, HamQTH, LoTW, eQSL.cc, n0) have their own privacy policies. qsonaut gives them nothing beyond what is described above.

The phone app

• The camera is used only to scan the pairing QR code on your computer's screen. The image is neither stored nor sent anywhere.
• The local network is used to find your computer and synchronise with it.
• The app collects no usage data and has no analytics, ads or tracking.
• A purchase in the App Store is handled by Apple; the author receives none of your payment details.

This site

qsonaut.app runs on Cloudflare, with no cookies, analytics or tracking scripts.

Your rights

The author keeps neither your log nor your personal data, so there is nothing to hand over or erase on the author's side. Deleting a log in the program, or the program itself, removes the data from your device. Questions: [email protected].
