Does PITTO work offline?

Yes. Your catalog lives on your Mac, so you can keep working without a connection.

PITTO checks its licence online at least once every 14 days. If it hasn't been able to for longer, it shows "PITTO needs to check your licence". Connect to the internet and it carries on; your catalog is untouched, and you can export it from that screen.

Song analysis, briefing PDFs and listening links need a connection. With a cloud library (two Macs on Pro), PITTO is read-only while offline.
