This page explains how study progress stays on your device.

Study data and language

Search terms and filters are not saved. Your selected language is represented by the URL path (Japanese at / and English at /en/) and is not stored as a separate browser preference. Study data is neither synchronized to a server nor linked to an account.

No third-party analytics or tracking

This site does not load third-party analytics, advertising tags, or behavioral tracking. It also has no feature that sends your study content or progress elsewhere.
