Data History
Zora keeps the boat's data over time for its history graphs. Data History is where you choose how long that data is kept, or clear it.
Open Data History
In the Setup app, open Add-ons & Third-Party, then the Extensions tab, and tap Data History. The panel says how long Zora keeps the data now: the last 24 hours, the last 30 days, or everything.
Choose how long to keep
Tap Retain last 24 hours or Retain last 30 days. Zora removes older data at its next clean-up, within half an hour, and from then on keeps only that span.
Delete all data
Tap Delete all data, then Delete to confirm. Every history graph starts again from empty and fills as new data arrives. This cannot be undone.
