Privacy Policy

Classroom sharing and sound

We count when teachers view or use classroom sharing tools. Targets are fixed labels for games, challenges, Daily, or grade pages. We never record a class name, roster, or child's name.

Classroom visits start with sound off. Sound choices during classroom visits last only until reloading.

What this policy covers

Last updated: October 11, 2026. We record fixed arrival labels and graphics-support signals. Referrers use an approved host list or a broad category. Supabase receives IP addresses and user agents at its gateway. Random session tokens exist only in memory and change on reload. They are never saved, reused across visits, or joined across days. Raw gameplay events are retained for 13 months; aggregate counts remain. Invalid analytics fields are removed or cleared. We count removed fields without recording their contents. We record policy violations using fixed directive and host categories. Each directive is reported at most once per page load. No blocked URL or page text is sent.
