Plugin Loco Translate

Hello,

Deleting the plugin will not delete any translation files.

Note that storing translation files in Loco Translate’s custom directory requires the plugin stays enabled. So if you plan to disable Loco Translate on your site, make sure you save all your translations in standard WordPress locations.
