Private by design
There is no cloud copy of your wording.
Snippets and notes live in a database on the computer. There is no Nevisel account, no telemetry and no activation server, and expansion never touches the network. Notes can be locked with a secret phrase.
Careful by default
Identifiers are refused, not stored.
Nevisel refuses snippets, shared phrases, notes and imports that look like a Social Security number, a labelled date of birth or a medical record number, and names the line to fix. It is a guard rail, not a guarantee: it cannot recognise names.
Governed by you
The approved version comes from your server.
On Windows, the shared library comes from your own Microsoft SQL Server. Only the editors it names can change it, every change writes an audit row, and each computer keeps a copy, so it works when the network does not.
