Your account settings cover your profile, how PackLash looks, and the units your trips use — all in one place.
Under Appearance, switch between Auto, Light, and Dark, and pin the sidebar expanded if you'd rather it not collapse. Under Weather units, choose °F or °C — this affects both the Go Day forecast and any AI Strategy suggestions.
When you create or edit a trip, the Trip type and Activities chip rows let you add your own options with + custom. The My custom types card in Account lists the ones you've added, with how many trips each is used on. Rename works any time; Delete is greyed out while a type is still used on a trip — remove it from those trips first, then delete it. Built-in types aren't listed here and can't be changed.
The Saved bags card manages your reusable bags — rename, share, or delete them, and open Edit items to change what's inside. The related article Reusing a bag across trips with saved bags has the full picture.
