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."
As a Kindle 2 owner who just had his Kindle updated to 2.5 firmware (which has this feature), I can tell you that this feature is off by default. In order for Amazon to actually share your highlights (of course, who knows if they're collecting it silently in the background; it's their system after all), you have to actively turn on this feature.
I've also seen Kindle for iPad. I don't recall whether this feature was on by default, but it is rather prominently displayed on their relatively simple options menu. If you have privacy concerns, it's fairly simple to turn it off.
Kindle User's Guide (pdf), page 99. Notes and highlights have been backed up to Amazon's servers since the v1 launch, and you can easily turn off sync of your own data.
You can enable or disable automatic backup by following the steps below:
1. If you are not already on the Home screen, press the Home button.
2. Press the Menu button.
3. Move the 5-way to underline "Settings" and press to select.
4. Press the Menu button.
5. Move the 5-way to underline "Disable/Enable Annotations Backup" and press to select.
Why should I care that Amazon builds an aggregate summary?
But it is an /optional/ feature, that they put out a press release for, put a big message on the amazon kindle forums about and are sending out an updated user's manual with. It is even a feature that defaults to off. They are telling people about it and letting them not turn it on. Otherwise it'd be terrible.
It'd make sense as a complaint if they didn't share what they were doing. There's also the option of not updating the software if you care so much about keeping the kindle exactly as it is.
The kindle store has problems, that doesn't mean that everything that amazon does with the kindle is a problem.
You're NOT automatically opted-in. Holy hell people... it's an OBVIOUS option in the settings menu that you must turn ON. I own a Kindle and I am not opted-into this. People here keep acting like there's no way you can keep your kindle from updating/phoning home/changing your settings. Now hear this: YOU CAN TURN OFF THE WIRELESS AND NOTHING CHANGES! Just turn it on when you want to download a book and turn it back off when you're done. Geez people...
