Amazon Is Collecting Your Kindle Highlights & Notes
TechDirt catches Amazon playing fast and loose with data that consumers may think is private — namely, their highlights and notes entered into Kindle books. "Amazon will now remotely upload and store the user notes and highlights you take on your Kindle, which it then compiles into 'popular highlights.' I have no doubt that the feature provides some interesting data, but it's not clear that users realize their highlighting and notes are being stored and used that way. Amazon basically says there's no big privacy deal here, because the data is always aggregated. But it sounds like many users don't realize this is happening at all. Amazon says people can find out they added this feature by reading 'forum posts and help pages.' ... [This situation] once again highlights a key concern in that the 'features' of your 'book' can change over time. Your highlighting may have been yours in the past, but suddenly it becomes Amazon's with little notice."
Collecting and anonymizing highlights to form something like "most popular passages". Awesome. Collecting and "anonymizing" notes? Impossible and terribly invasive.
Guess which one is actually happening? Guess which one the title and summary suggests is happening?
As a (recently) former employee (new gig) of Lab126, the people who make the Kindle, I can assure you that only highlights are used in data collection, i.e. the selection from a start location to end location. When shown as popular highlights, they are just an underlining of text for those locations, as well as the number of users who have highlighted that selection. That is it, nothing more, nothing less.
No annotations are used that people have typed. Finally, the service is optional, with the ability to opt-in and opt-out on device. I'm pretty sure this has been stated in the kindle users guide, the legal menu item in settings, and on the website.
