班级名单
保存一次班级名单，处处可用 — 一键发送到转盘、分组、座位表或计分板。数量不限，仅存于浏览器。
我的班级名单存在哪里？
完全保存在本设备的浏览器本地数据库（IndexedDB）中——比 Cookie 和缓存可靠得多。不上传任何数据、没有账号，学生信息永不离开本设备 — 详见隐私政策。请使用同一浏览器和设备以保留名单。
One list, the whole classroom
Most picker sites make you retype names on every tool. The roster center fixes that: save “Period 2 — Science” once, and every tool on this site gets a Load class dropdown. The wheel, the group generator, the seating chart and the scoreboard (auto-build teams) all read from the same rosters.
Paste straight from Google Sheets or Excel — the first column becomes your list, duplicates can be removed with one click, and classes can be sorted A-Z or shuffled.
FAQ
What is the roster center?
A place to save your class lists once — then load them into the name wheel, group generator, seating chart and scoreboard with one click instead of retyping names everywhere.
How many classes can I save?
Unlimited, free. Multiple periods? Save each as its own class (e.g. “Period 2 — Science”). Nothing is locked behind a paywall.
Where is my data stored?
In your browser's local storage only — no account, no upload, no server copy. That's the COPPA-friendly posture described in the privacy policy.
Can I import from Google Sheets or Excel?
Yes — copy a column of names and paste it into the new-class box; only the first column is used, one name per line. CSV files work the same way.
What happens if I clear my browser data?
Local storage is erased with it, so rosters would be lost — export/copy your names to a spreadsheet termly if that worries you.
