Privacy
Your notes stay in your browser.
There is no account or login. We do not keep a central database of what you type into a worksheet; it stays on your device.

Saved work and backups
Worksheets may save notes in this browser. Download a backup for anything important because browsers can clear their own data, and CommonCrew Labs cannot recover a local worksheet for you.
To remove a worksheet, clear BandBoosterKit's site data in your browser and delete any CSV, print, or backup files you saved. Because those copies are on your device, CommonCrew Labs cannot delete them for you.
Analytics
BandBoosterKit does not use analytics and does not send worksheet contents to an analytics service.
What to keep out of the worksheets
Do not enter full private rosters, student balances, payment records, hardship notes, medical details, emergency contacts, room assignments, addresses, parent phone lists, card or bank data, tax IDs, credentials, or official records.
Privacy questions and email deletion requests
Email [email protected] with a privacy question or a deletion request for an email you sent us. Please do not include student records, payment details, medical information, or other private program data.
