In your Home Area, click the three dots in the top right corner and select Account Settings.
Select the "Language" option on the left of the screen, then access the drop-down menu to select your preferred language. Wakelet will then update your preference immediately.
We currently offer a limited number of language options as we continue to roll out this feature, so if we don't have yours just yet there's a good chance we're working on adding it as soon as possible!
