Privacy Policy

Last updated: October 2026

What the app doesn't do

• No accounts or sign-in. The app never asks for your name, email address, or any other personal information.
• No analytics, crash reporting, advertising, or third-party tracking of any kind.
• No developer-run servers. The app never connects to a server of its own, because it doesn't have one.
• No device permissions. The app does not request access to your location, camera, microphone, contacts, or any other protected data.

What is stored on your device

To work, GROL Trainer saves a small amount of information locally on your device only:

• Your quiz history and practice statistics, such as which questions you've answered and your results by topic.
• The date your free trial started.

This information is stored in the app's own on-device storage. It is never sent anywhere, never synced to a server the developer controls, and never shared with anyone.

In-app purchases

GROL Trainer offers a one-time unlock purchase through the App Store. Apple processes the purchase, and the developer never receives your payment details or personal information. Apple's handling of purchase data is covered by Apple's Privacy Policy.

Children's privacy

Because the app collects no personal data from anyone, it collects none from children.

Changes to this policy
