Seattle 2026 is a companion app for a patient going through an extended course of treatment and the family members helping them. It shows the patient's appointments in a simple day-by-day schedule.
When you connect MyChart, the app asks your health system for read-only access to your appointments, your name, and the clinic locations attached to those appointments. It does not read clinical results, notes, medications, messages, or billing.
Appointments are written into an Apple Calendar on your device that you choose. If that calendar is shared through iCloud, the people you shared it with see the appointments in the same way they see any shared calendar. Nothing is sent to the app's developer or to any third-party server. The app has no accounts and no analytics.
You can disconnect MyChart at any time from the app's Settings. Disconnecting removes the app's access; appointments already on the calendar stay there until you delete them. You can also revoke the app's access from within MyChart.
The app displays scheduling information from your health system. Always confirm details with your care team.
