Changes in the new policy include Reddit support to the Do Not Track, changes to the length of time that user IP address are sorted on Reddit servers, Huffman details that in the future they’re looking to avoid storing IPs at all. These changes will take effect on January 1.
With this changes Reddit showing the world how little information they are actually collecting from the users, for ex: you can still opt a reddit account without even providing email address.
Exctract from Huffman post on reddit:
The new policy is functionally very similar to the previous one, but it’s shorter, simpler, and less repetitive. We have clarified what information we collect automatically (basically anything your browser sends us) and what we share with advertisers (nothing specific to your Reddit account).
One notable change is that we are increasing the number of days we store IP addresses from 90 to 100 so we can measure usage across an entire quarter. In addition to internal analytics, the primary reason we store IPs is to fight spam and abuse. I believe in the future we will be able to accomplish this without storing IPs at all (e.g. with hashing), but we still need to work out the details.
Individually, you have control over what information you share with us and what your browser sends to us automatically. I encourage everyone to understand how browsers and the web work and what steps you can take to protect your own privacy. Notably, browsers allow you to disable third-party cookies, and you can customize your browser with a variety of privacy-related extensions.
We are proud that Reddit is home to many of the most open and genuine conversations online, and we know this is only made possible by your trust, without which we would not exist. We will continue to do our best to earn this trust and to respect your basic assumptions of privacy.
