I do not have the language skills to validate whether your RU and LV translations are correct however I can tell that, if I use Google Translate, the obtained text is a lot closer to the other translation meanings 😉

Hello @zucha ,

I don't see the fix with your PR.

I tried to update the module psgdpr, I tried installing the shop in latvian and russian, I updated both languages from the BO.
But I still get the gdpr message in English in the shopping cart and in the customer account area.

Am I missing something ?
