Privacy

Your progress is stored in your browser on your device. We have no user database.
We collect cookie-less analytics with PostHog: the profile name you typed (a nickname is fine), a random device id, pages, your level and test results (including which questions you got right or wrong), your STEP score if you choose to share it, device type and approximate country. We never send your writing or the text of your answers.
If "Do Not Track" is on, nothing is sent. You can also turn analytics off from the in-app privacy page.
Feedback messages are received via Netlify Forms and used only to reply and improve the site.
