What is a useful first privacy check for smart glasses?
Follow one low-sensitivity interaction from start to finish and inspect the visible controls and resulting records. Choose something harmless so the exercise itself does not require exposing private information.
Check the lifecycle of one item
Create a short test note or request with recognizable wording, then see where it appears and what the app offers for removing it. This can establish observable behavior in the interface. It cannot prove that every server copy has been removed without supporting documentation or other evidence.
Use a made-up phrase rather than a real meeting detail. After stopping the feature, reopen the app and look for the resulting item. If you delete it, distinguish disappearance from the interface from the service's stated retention behavior. Both facts matter, but they answer different questions.
