Terms of Use
Effective November 15, 2026
Gadaj is made by CommonGroundTech, LLC and licensed to you under Apple's Licensed Application End User License Agreement (the standard EULA). That agreement is the terms of use for Gadaj. The notes below summarize how Gadaj Pro subscriptions work.
Gadaj Pro subscriptions
- Units 1 and 2 are free. Gadaj Pro unlocks every unit and is available as a monthly or yearly auto-renewing subscription. Prices are shown in the app before you subscribe and may vary by country.
- New subscribers get a 7-day free trial. If you don't cancel before it ends, the subscription starts and you're charged. Any unused part of a free trial is forfeited when you buy a subscription.
- Payment is charged to your Apple Account when you confirm the purchase, or when the trial ends.
- Your subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
- Manage or cancel any time in your iPhone's Settings > your name > Subscriptions. Deleting the app doesn't cancel a subscription.
- Refunds are handled by Apple at reportaproblem.apple.com.
The course
Gadaj is a learning aid. We work hard to make its Polish natural and correct and its scoring fair, but speech recognition isn't perfect and we can't guarantee any particular result.
