Would you let Apple listen to your whole day?

At Nike we made the FuelBand, and I do not think anyone ever saw it as a device that you couldn't always wear. I even slept with it. It was an extension of your identity. If you took yourself seriously as an athlete, and you were a real 'Nike guy', plus you wanted to know what you had burned that day, you wore one. As well as the matt black Nike Apple watch.

On the Nike EHQ campus you never wore a watch or earrings to play basketball. FuelBands were the exception, and nobody argued about it. It was a Nike product and we worked there. It was 25 games, and I only got one comment.

On 9 September Apple confirmed a feature for Apple Watch Ultra 4 called Siri Recap. It listens to a conversation in the background and writes a summary afterwards. Live Rewind, a second feature, reads back the last 15 seconds of what was just said.

Apple says the audio is never stored. For Live Rewind it built in a signal, a chime and a lit screen, so people nearby know. Apple's description of Siri Recap mentions no chime.

Nobody is going to ask a client to turn their watch off, so the only question left is what happens to what it hears.

A watch is not equipment. Nobody in the room clocks it, the way nobody clocked a FuelBand on a basketball court, and that is not a flaw in the product. It is the product.

Give Apple its due, because the engineering is the good half here. The audio is handled on the device and deleted when it is done. That is a stronger position than most of the software you already run.

But a summary is a document, and a document goes somewhere. It is made out of a conversation you were half of, it sits on a device you do not control, and you will never read it.

It's not like right or wrong, it's like, how wrong is it. A summary of a run is nothing at all. A summary of a pricing call, a renewal, or a complaint is a different object, and the difference is not in the watch.

The part that is easy to miss is that the person wearing it may not know either. Features like this arrive in an update, and nobody reads the update. So a meeting gets written up by something neither person in the room decided to bring, and both of them would be surprised to hear it.

So the question is not whether it works. It is whose hands the summary sits in. A conversation with a client, a number you should not have said out loud, a complaint.

That is Apple's now, on their terms, and those terms change in an update you will not read.

Do you trust them with it?
