We crowd-source our dashboard translations. If you notice ways in which the translation could be improved, we'd love to add you as a collaborator! We utilize PoEditor.com as our collaborative translation tool. If you're current with your paid subscription, and would like to be added as a contributor, just message us from within your dashboard to let us know. We'll get you added, and you can then go through and make any suggested changes that you see fit. You then let us know when you've finished, and we give the changes a final review and push them live to the dashboard.
Note that we do not grant "free subscriptions" or discounts in exchange for assistance with translations. We offer the ability to assist with translations as a service to our customers in the spirit of a collaborative effort.
