Privacy & how it works

Terrawatch 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, no camera

There is no sign-up and no login. There are no ads and no in-app purchases, and no third-party trackers. Unlike the iOS field app, the web version never uses your camera or location — you practice the science skills (classifying, reading data) with built-in observations.

Built for ages 9–14

The 400 questions come straight from the Terrawatch iOS app and are aligned to NGSS science standards. The two field labs ask you to PREDICT before the answer is revealed — the best-evidenced way to learn science — with a hint only after a first try. Mistakes are treated as part of learning.

Science that helps

Terrawatch shows the environment through what science and communities can DO — planting habitat, cleaning up, restoring wetlands. Real citizen-science data is how we see progress. There's no doom here, just noticing, evidence, and hope-forward action.

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