They know us better than we know ourselves: how Amazon tracked my last two years of reading

When I requested my personal information from Amazon this month under California’s new privacy law, I received mostly what I expected: my order history, shipping information and customer support chat logs.

But tucked into the dozens of files were also two Excel spreadsheets, more than 20,000 lines each, with titles, time stamps and actions detailing my reading habits on the Kindle app on my iPhone.

I now know that on 15 February 2019 starting at 4.37pm, I read The Deeper the Water the Uglier the Fish – a dark novel by Katya Apekina – for 20 minutes and 30 seconds. On 5 January 2019 starting at 6.27pm, I read the apocalypse-thriller Severance by Ling Ma for 31 minutes and 40 seconds. Starting at 2.12pm on 3 November 2018, I read mermaid romance tale The Pisces by Melissa Broder for 20 minutes and 24 seconds.
