Trust grows from behavior as well as statements. A clear permission request, an honest explanation of storage, and an accessible way to leave all help a person understand a service.
Good defaults and plain language reduce the effort needed to make a decision. Important actions should show their consequence before they happen and confirm what changed afterward.
A service should also handle uncertainty clearly. If an action has an unknown outcome, a confident success message is less useful than a truthful state and a practical next step.
Try the idea in context.
Imagine a form explaining what happens after a submission before the reader commits. Clear expectations make the decision easier to understand.
