Privacy & how it works

GrammarForge on the web is built the same way as our iOS apps: private by design.

Everything 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.

Spark & Anvil is a 501(c)(3) public charity. Apps stay free forever. This page is a plain-language summary, not legal advice.
