Nest CEO and ‘father of the iPod’ Tony Fadell has responded to data privacy concerns expressed after the company was acquired by Google, stating that there have not yet been any changes to the data collected by the smart thermostat and smoke detector, and that any future changes would be both transparent and opt-in.

At this point, there are no changes. The data that we collect is all about our products and improving them.

If there were ever any changes whatsoever, we would be sure to be transparent about it, number one, and number two for you to opt-in to it … 

Fadell gave the assurances during an interview at the Digital-Life-Design conference (via TNW). He also said that he was excited by the conversations he’d had with Larry Page and other Google execs when discussing future plans.

We were finishing each other’s sentences, and the visions that we had were just so large and so great, and they weren’t scared by them. We were both getting exhilarated by what could change and how things could change, and that we could have the ability to change those things together.

Apple senior VP Phil Schiller unfollowed both Fadell and Nest on Twitter following the acquisition.
