Theme, language and zoom

How shared preferences work across every Nucleo surface.

Updated Jul 3, 2026

Every public Nucleo surface exposes a preferences control (the gear icon in the header). Your choices are stored against the .nucleo.company domain so they persist across subdomains.

What you can change

Theme — System, Light or Dark. Dark is the default.
Language — English, Portuguese or Spanish.
Zoom — scale the interface between 80% and 110%.

Set it once on any surface and it applies to Hub, Help and Chat the next time you visit them.
