How can I add own translation to the plugin?
Unfortunately, at the moment our plugin do not support adding of manual translation from the user side. We do not provide any guarantee of properly work of the plugin for manually added custom translations and also do not provide any guarantee that manually added translation won’t be overwritten after plugin update.
The most preferable way is make a translation of 3 .po files as described in this article of the plugin documentation via free translator Poedit or other suitable way and send us these files for integration via direct email address: email@example.com.
In this way you help other users to have our plugin on their languages and also prevent translations overwriting after plugin updates, because we work on improvement of our plugin and sometimes make changes of files with translation.
