Size is part of an item's identity — a 19.2 oz Miller Lite is its own item, not a variant of the 12 oz.

An export is the one copy of your data that leaves the browser. The encrypted form is the one to keep.

Preferences
Volumes are stored internally in millilitres, so switching unit only changes how they are shown — nothing is converted or lost. "Standard drink" is not universal; pick the definition your health guidance uses. The target draws a reference line on the chart — it is context, not a verdict. The key is held only in memory: locking, closing the tab, or idling past the limit discards it, and the store on disk stays encrypted.
Erase this store
Deletes the encrypted store from this browser. Irreversible, and it does not touch any exports you've already saved elsewhere.
