Quick Answers

Are ClearHalf's estimates medical advice?
No. ClearHalf gives informational estimates to help you plan. They are not BAC, sobriety, or driving clearance, and should not be the sole basis for safety-critical decisions.

Does ClearHalf work offline?
Yes. Forecasts and estimates run on-device and continue to work without an internet connection.

How do I remove my data?
Delete individual logs in the app, use "Delete all my data" in Settings, or delete the app to remove local data.

How do I manage my subscription?
Open iOS Settings -> Apple ID -> Subscriptions.

Why don't my widget, Live Activity, or watch match the app exactly?
They refresh on a schedule set by iOS. Open the app to pull the latest estimate, and they will catch up shortly after.
