The German localisation of the newish "save your watch streak" notification is very odd: The word "rettenpeichern" does not exist, it's been there for months, any spellchecker flags it, too. It looks like an accidental mixture of retten and speichern.
It's as nonsensical as saying "to savrescue your watch stream..." with save+rescue pasted into each other.

PS:
This "UserVoice" page's localisation also reads like it was translated as unrelated strings without context, someone please proof-read it in the order it appears on the screen.
"UserVoice möchte auf dein Konto zugreifen. Durch die Autorisierung wird UserVoice Folgendes gestattet:

("You allow us the receipt of your user ID, and, read your email address!" makes no sense, does it mean "and to read your email address"?)
