Privacy & how it works

CrownTales 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. The AI opponent runs entirely on this device.

Built for ages 9–14

The 400 Concepts questions come straight from the CrownTales iOS design. Losing a piece is framed as a trade to study, never a scold, and the AI opponent scales from Gentle to Sharp. A hint appears only after a first try.

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