Frequently Asked Questions
How is my BAC calculated?
Night Out uses the Widmark formula, personalized to your age, weight, height, and biological sex. It's an estimate — not a medical measurement. Never rely on it to make legal decisions like driving.
Is my data shared with anyone?
No. Everything you enter stays on your device. Night Out does not collect, store, or transmit any personal data.
Can I change my profile info after setup?
Yes. Tap the settings icon in the top right corner of the home screen to update your age, weight, height, and biological sex at any time.
How do I end a session?
Tap the red "End Session" button at the bottom of the active session screen. Your session will be saved to Past Sessions automatically.
Can I delete past sessions?
Yes. Swipe left on any past session to delete it. Deleted sessions cannot be recovered.
The app isn't working as expected. What should I do?
Try closing and reopening the app. If the issue persists, delete and reinstall Night Out from the App Store. If problems continue, contact us below.
Privacy
Night Out does not require an account and does not connect to the internet. All data — including your profile, drink logs, and session history — is stored locally on your device and never shared.
