Родной язык в Украине is a free Chrome add-on developed by Akilrajas. It falls under the category of Browsers and subcategory Add-ons & Tools. This add-on aims to address the issue of Ukrainian websites defaulting to the Ukrainian language interface. While most of these websites provide a switch to the Russian language option, it often resets after a certain period of time or browser restart. This add-on automatically switches the interface language to Russian on supported websites. Users have control over which websites the add-on can work on.

The add-on supports a range of websites including entertainment, news, banks, and internet service providers, with the list expected to grow over time. To view the list of supported websites, users can visit the extension page in their browser and click on the "Details" page of the add-on.

In terms of security, this add-on only interacts with supported websites within the necessary boundaries to switch their interface language. No data is collected or sent. Users can verify this by examining the source code, which is available for download and extraction from a zip archive. If users do not want the add-on to have access to a particular website, such as a banking site, they can disable access by visiting the extension page in their browser and navigating to the details page of the add-on.

Note that some websites control the interface language through cookies. If cookie reception is not allowed for a particular website in the user's browser, the add-on will not be able to switch the interface language and may, in some cases, cause cyclic page refreshing. Fortunately, there are only a few websites that use cookies in this manner.
