Using Smart Logbook's check-ins, summaries, and recommendations is optional. You can turn off auto-generated logbook summaries two ways:
Tap the plus button at the bottom of the app, then Summary, then the "here" link under the performance explanation.
Tap your profile icon, tap the ellipsis (three dots) in the upper right corner, go to Privacy and Settings, scroll down to "Auto-generate logbook summaries," and toggle it off.
