Beta feedback
In the TestFlight app, open Showbook and tap Send Beta Feedback, or take a screenshot in Showbook and choose Share Beta Feedback. Screenshots help most.
Delete your data
Email wolf@schram-media.com with the subject "Delete my Showbook data". We delete it within 30 days and confirm by email. Removing the app deletes everything Showbook stored on your device.
Calendar access
Showbook can show your own calendar next to the project. That's read on your device only and never leaves it. You can turn it off in iPhone Settings › Showbook › Calendars.
