What to know before you use it
How to use this feature well
Distinguish device-only operational records from account, backup, analytics, advertising and community data; each control has a different storage and deletion boundary.
Where the information comes from

Check your inputs
Configure privacy, ads and backup: Complete missing information and correct inconsistent or out-of-range vessel, position and calculation values.
Understand the calculation
Configure privacy, ads and backup: Keep the units, vessel particulars, time zone and selected method in view when reading a result or export.
When to stop and review
