Head Tracker+Voice+Instructor

Privacy policy

In short: we have no servers. Head Tracker+Voice+Instructor does not send us anything, has no account, no advertising and no tracking. Everything happens on your own devices — your iPhone and your Windows PC. The only exception is optional: if you turn on the Claude instructor with your own Anthropic key, its questions go directly to Anthropic, not to us.

On your iPhone

  • Camera. The front camera (the one used for Face ID) follows your head. The image is used on the iPhone to work out the position of your head; the app does not record photos or videos.
  • Voice commands. Speech is recognized on the iPhone with Apple’s speech recognition. Apple’s privacy policy applies to that service. The microphone is used only while voice commands are on.

Between your iPhone and your PC

The iPhone sends the position of your head and your recognized commands to your PC — through a cable, or over your own Wi-Fi network. The first time, both devices show the same code and you confirm it. This data stays between your two devices.

On your PC

The Windows program turns the head position into the view in the game, presses the keys for your voice commands, and runs the instructor. The instructor speaks with a voice installed in Windows. All of this happens on your PC, without an internet connection.

Claude instructor (optional)

If you choose to turn on Claude, you use your own Anthropic account and key. The instructor’s questions and the flight information they need are then sent directly from your device to Anthropic, under your account. Anthropic’s terms and privacy policy apply. We never receive these requests or your key; the key stays on your device. Without Claude, the instructor works offline.

What we never collect

  • no account, no sign-in;
  • no analytics, no advertising, no trackers;
  • no camera images, no voice recordings, no flight data sent to us.

Reports and messages you send us

If you decide to send us a report or a question (by e-mail or on GitHub), you choose what it contains. We use it only to answer you and fix problems, and we do not share it.

Apple

The app is distributed by Apple (App Store, TestFlight). If you allowed it in your iPhone settings, Apple may share crash reports with developers; this is governed by Apple’s privacy policy.
