Yahoo is rolling back its policy on storing user information

In 2008, Yahoo! It was one of the first IT companies to offer to introduce something like the “anonymity” policy of its users, significantly reducing the retention of user search queries and all user information, such as page browsing and ad block clicks. For the most part in a significant reduction in the retention period for user information - up to 90 days, after which the logs were erased. users perceived this move very positively, and today the corporation announced a “rollback” of this policy.

The reason for this move is not explained, however, the storage period for user information, the types of which were discussed above, is extended to 18 months. Such information is usually used to personalize the content of web pages, as well as to “fine tune” targeted advertising. Perhaps the corporation plans to increase the retention period of user data in order to continue research in the field of online advertising, conducting a study of logs about user requests, page views and clicks on ad units.

Other reasons are less clear - unless cooperation with the authorities? But large IT corporations, especially the USA, do not often allow the state to launch its hands into the holy of holies - databases on its users. In general, Yahoo! just notified everyone about the extension of the retention period for user requests and some other information.

According to the developers, any information that can help identify a particular user is usually erased. But who knows whether this is true, or now such information will also be stored. In principle, for users of CIS countries, Yahoo! don't matter much since the popularity of Yahoo! as a search engine we are not particularly great. But in the US, the situation is quite different.
