How are BAC values calculated?

SipWiser uses the Watson formula with your sex, age, weight, and height to estimate total body water. Each sip absorbs into the bloodstream independently (first-order kinetics) and the liver eliminates a fixed 0.015 g/dL per hour from the total. Numbers are estimates — never use them to decide whether you're safe to drive.

Why does a session sometimes close while I'm still drinking?

Sessions auto-close when your estimated BAC has been zero for 90 minutes (or after a 90-minute gap if you've turned BAC off). Add a sip and a new session starts automatically.

I signed in on a new device — where's my history?

Pull-to-refresh on the Home screen forces a fresh sync from the server. If you still don't see anything, your previous sessions may have been on a different account; the email shown in Settings is the one your data is keyed to.

Can I export my data?

Yes. The /delete-account screen offers a one-click JSON archive of every sip, session, preset, profile setting, and goal before you delete. You can grab the archive without deleting if you just want a backup.

Where do I report a bug or request a feature?

Email support@sipwiser.app with as much detail as you can — what you tried to do, what happened instead, your phone or browser, and a screenshot if you have one.
