How can I translate the 'remember me' label at checkout?

Hello,

I hope I chose the right category. I tried to edit the “remember me” label at checkout from “edit default theme content” and from the json file but I could not find it.

I tried contacting customer support as I am using Kalles theme(3rd party) but they said that this field is generated by an app and they can’t help me.

Do I need to hire a developer to do this ? Are there other options I can try?

Thank you in advance!
