The short version
- We do not sell student data.
- Students should not need email, phone numbers, home addresses, or personal accounts to use Big Brain Labs classroom tools.
- Most tools are local-first: rosters, seating charts, notes, and classroom setup data stay in the teacher's browser unless a feature clearly says it uses cloud sync.
- Teachers control classroom rosters and should clear local classroom data at the end of the school year or when a device changes hands.
What students should enter
Student-facing activities should ask for the minimum needed to run the classroom activity. A first name, nickname, team name, or class code may be used when a teacher starts a session. Students should not enter email addresses, phone numbers, home addresses, birthdays, or other identity details unless their teacher has specifically directed them to do so for a school-approved reason.
What stays on the device
Local-first tools such as timers, manipulatives, seating, planning, and most classroom utilities save data in the browser on the device being used. Big Brain Labs does not receive that local classroom data.
When cloud sync is used
Some collaborative classroom features need a server so students can join from more than one device. When that happens, the product should say so clearly. The full data breakdown lives in the Privacy Policy.
