Privacy Policy
Effective November 15, 2026
The short version: Gadaj doesn't collect your personal data. There's no account, no ads, no analytics or tracking, and no third-party code in the app. Your progress stays on your iPhone, your voice is handled by Apple's speech recognition, and payments go through Apple.
Gadaj is an iPhone app for learning Polish, made by CommonGroundTech, LLC ("we", "us"). This policy explains what happens to your information when you use it.
What stays on your iPhone
Your lesson progress, best scores, practice days and streak, and your settings (speaker gender, learning goal, sounds, reminder time) are stored only on your device. We never receive them. Deleting the app deletes them. Like any app data, they may be included in your iPhone's own iCloud or computer backup, which Apple manages for you.
Your voice
When you tap the microphone, Gadaj uses your iPhone's microphone and Apple's Speech framework to turn what you say into text, then compares that text with the Polish phrase to score each word. On iPhones that support it, recognition runs on the device itself. On others, Apple processes the audio on its servers under Apple's Privacy Policy. Gadaj doesn't record, store or send your audio or transcripts to us. It keeps only the score.
You can turn off microphone or speech recognition access for Gadaj at any time in Settings > Privacy & Security. Speaking exercises won't work without them, but you can skip them.
Purchases
Gadaj Pro is sold through the App Store. Apple handles payment, and we never see your payment details or Apple Account. The app asks Apple whether your subscription is active so it can unlock Pro units.
Reminders
Daily reminders and come-back nudges are scheduled on your iPhone. They're not sent from a server, and you can change or turn them off in the app's Settings or in your iPhone's notification settings.
Crash reports and App Store data
If you've chosen to share analytics with app developers in your iPhone's settings, Apple may send us crash reports and usage statistics. Apple doesn't identify you in them. We use them only to fix problems. Apple also gives us aggregate App Store data such as download counts.
Children
Gadaj isn't directed at children under 13, and since it doesn't collect personal data, it doesn't knowingly collect any from children.
Changes
If this policy changes, we'll update this page and the effective date above. If a change ever means Gadaj starts collecting data, we'll say so in the app before it happens.
