GrammarForge on the web is built the same way as our iOS apps: private by design.
Your work stays on this device
Your progress — best scores and XP — is stored only in this browser (on-device storage). It is never sent anywhere. Clear your browser data and it's gone; nobody else can see it.
No accounts, no ads, no tracking
There is no sign-up and no login. There are no ads and no in-app purchases. There are no third-party trackers embedded in the app.
Built for ages 9–14
The 400 questions come straight from the GrammarForge iOS app and are aligned to CCSS ELA-Literacy language standards. A hint appears only after a first try — you think it through first, and mistakes are treated as part of learning.
