What the app does with your data

ATC Phraseology & Readback stores your practice progress on your phone: which scenario cards you have studied, your drill scores, your practice days and streak, and your settings (phraseology variant, callsign, aircraft type, speech speed, theme). The app has no account, no backend, no cloud sync, no ads and no analytics or advertising SDK. The app itself sends nothing to any server.

What is collected

• Diagnostics (App info and performance): collected, not shared, required. This is the technical data Google Play Billing handles when you buy, restore or manage Pro. We do not receive your card or payment details; Google does.
• Nothing else is collected: no name, email, location, contacts, photos, files, microphone audio, camera data or device identifiers.
• The callsign and aircraft type you type in are used only to fill your radio calls on screen and in speech. They stay on the phone.

Speech

The app does not record audio and does not ask for the microphone. When you tap Listen, the text of a call is passed to the text-to-speech engine installed on your phone. Which voice is used, and whether that engine works online or offline, is decided by that engine and your phone settings, not by this app.

Permissions

The app asks for no runtime permissions. It does not use location, camera, microphone, contacts, notifications or storage permissions. The manifest lists only the billing, internet and network-state permissions that the Google Play libraries need to sell Pro and show the review prompt. Export and the PDF cheat sheet save a file only where you choose, through the system file picker.

Your controls

• Settings > Export all my data saves your progress, practice days and settings as a JSON file you choose.
• Settings > Delete all data erases progress, streak, settings and cached files from the phone and returns the app to a fresh install. A Pro purchase belongs to your Google account and is not affected.
• Settings > Manage subscription opens Google Play subscription management. Cancel the yearly plan any time in Google Play.
• If Android backup is on for your phone, the app database and settings can be stored in your own Google account backup. You can delete that backup from your Google account. The purchase cache is excluded from backup.
• Uninstalling the app removes its local data.

Training material

The phraseology is written for practice, in the style of public FAA and ICAO standard phrases. It does not replace the AIM, ICAO Doc 4444 or your instructor.

Children

The app is not designed for children under 13 and does not knowingly collect their data.
