Does Gboard send the whole message when you ask it to change one word?

You're dictating a family message with an address in it. One word is wrong, so you ask the keyboard to change it. That can feel like continuing the same private dictation session. Google's existing Gboard guide draws a distinction worth knowing: advanced voice typing keeps the dictated text on the device, except when using ‘Fix it’ or detailed edits. For detailed edits—commands such as ‘Change apples to oranges’—Google says the command transcript and the full text in the input field go to its servers for processing. It says no audio is sent and no text or audio is stored on those servers. That detailed-edits section applies to Pixel 8 and later in English (US). Don't extend it to every voice correction: the same guide separately describes newer voice-controlled writing tools on Pixel 9 and later, excluding 9a, whose proofreading and rewriting happen on the device. If you don't want to use the server-processed edit, the guide also describes selecting a misheard word and typing a correction. That avoids this particular voice-edit request; it isn't a privacy guarantee for the app you're writing in. I'd want ‘Uses Google servers for the full message’ explained before a detailed edit, not left for someone to discover in help. This is a reading of the documentation, not a traffic test or a claim that the current screen lacks a notice. I'd want to know whether the rest of that family message leaves the phone before asking for a one-word fix.
