There are a lot of strings of text that it would not make sense to translate and not be wise to send to a remote translation service, like strings of digits, blocks of base 64 encoded text like ssh keys, digits and letters separated by punctuation like phone numbers and bank account numbers, etc.

Perhaps Google Translate should filter out non-word private tokens from the original text (replacing them with opaque identifiers that aren't translated but are left alone, and substituting the originals back into the translated text).

(PS: Are you still in the shower, posting on one of those new-fangled waterproof phones? Hopefully not a Google Glass!)
