No warranty
The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and non-infringement.

Privacy
This website (quil.cc) sets no cookies, runs no analytics, and makes no third-party network requests except to Google Fonts for the Inter and JetBrains Mono webfonts used on this page. It loads static HTML, CSS, and SVG from GitHub Pages.
Quil itself, when installed, stores all state locally under
~/.quil/. The workspace snapshot, ghost buffers, plugin
configs, and logs never leave your machine. There is no telemetry, no
usage reporting, no auto-update phone-home. Quil does not open any
outbound network connections on its own — only the commands you run
inside a pane do.
Your responsibility
Quil is a general-purpose terminal multiplexer. What you run inside a Quil pane — network tools, scrapers, AI tools, databases, third-party APIs — is your responsibility, and subject to the laws of your jurisdiction, the terms of service of any network you connect to, and any agreements you have with third parties. Quil does not facilitate, assist, or endorse any particular use case.
