Terms of use

These terms cover EGG — English Grammar Game / Spot 'n Tap Errors, provided by Nexus Learning. Using the app means you accept these terms.

The app is a grammar drill. Questions come from a prepared CSV. Scoring happens on your device. You need a Google or Microsoft account to practice. After you sign in, progress can sync to Firebase (the project configured for this deployment). Exporting progress to a spreadsheet is optional and only creates a new file (drive.file). Existing spreadsheets are not opened. The standalone web app is free.

Do not break in, use someone else’s account, copy or redistribute the question bank, or use the app in a way that breaks the law.

The app is for learning. We do not promise exam scores or that every item is perfect. We are not liable beyond what the law requires.

Progress is also stored in this browser (localStorage). After you sign in, it is stored in Firestore for the configured Firebase project.

Questions, explanations, and other content belong to the operator or the rightful owner. Do not copy, change, or redistribute them without permission.

These terms may change. The new text applies when it is posted on this page.
