Annoying things we learned while developing Kondis.

Strava takeout files are silently translated

Importing takeout data

Strava takeout files depend on a hidden language setting. If you don't have English preselected, your takeout data fields will be in whatever language Strava is set to, meaning it is very difficult for other apps (including Kondis) to read. Also, you can only do one takeout per account per week, so if it isn't right the first time, you have to wait a week to try again.

Strava takeout crops are cursed

Importing edited activities

Strava takeouts do not store activity crop boundaries. The takeout can contain the original, untrimmed activity file while activities.csv contains summary metrics for the edited activity. Because there is no crop information, Kondis cannot import that edit faithfully. Each cropped workout needs to be re-cropped manually.
