About you as a user: your name, role or trade, your phone and email if they're added, and your saved signature (it only ever signs for you).
Staff records: contact details, address, emergency contacts, licences and tickets with photos and expiry dates, apprentice details and leave. Some businesses add health information, such as allergies or medical notes for emergencies. That's sensitive information: it should only be added with the person's OK, and only admins and that person can see it.
Job information: customer names, contacts, phone numbers and site addresses, job descriptions, photos, test results, JSAs and signatures, hours with start and finish times, parts orders and notes.
From Xero, if you connect it: your organisation's name, contacts, item codes, and invoice numbers, statuses and dates. Owners and admins also see invoice totals and amounts owing, read from Xero when they look. They aren't saved in WirePilot and crew don't see them. WirePilot never sees your Xero password, and the Xero connection isn't stored on phones.
How the app gets used: counts of how often each section is opened, not who opened what.
From our website: your email address, if you join the early access list.

We don't track where you are. Photos can carry a location if your phone's camera saves one.
