A hardened pick. Worth the effort once you have chosen to shrink your footprint on purpose. Enough for most people. Threat levels
Our take
The spreadsheet counterpart to Etherpad, handy for real-time shared tables without a Google account in the way. Same blunt caveat applies and matters more with numbers: it is unencrypted, so the host sees your data, and license info is unclear here. Fine for collaborative, non-sensitive calculations on an instance you control; reach for an encrypted tool the moment the figures are private.
