Data Storage and Anonymisation

Please note that our user log retention policy has been updated and you can get more information about the changes here.

In order to provide products and services, Yahoo!7 collects and stores information from user account registration and site usage. We generally refer to the information that we collect in connection with site usage as “user log data”.

Yahoo!7’s policy is to de-identify search user log data within 18 months of collection, with limited exceptions to meet legal obligations.

In addition to the other purposes for which we collect information, other types of log data (ie not relating to search) (such as ad views, ad clicks, page views and page clicks) are retained for a longer period in order to power innovative product development, provide personalized and customised services, and better enable our security systems to detect and defend against fraudulent activity. Yahoo!7 takes additional steps so that data collected and used to customise interest based advertising (along with some content) on Yahoo!7 are not associated with personally identifiable information. We describe the data we store, and our processes in more detail here.

Yahoo!7

Account Information

  • When you register with Yahoo!7 or submit information to Yahoo!7, a temporary copy of that information is routinely made to prevent accidental loss of your information through a computer malfunction or human error.
  • Yahoo!7 keeps your account information active in our user registration databases in order to provide immediate access to your personalisation preferences each time you visit Yahoo!7.
  • If you ask Yahoo!7 to delete your Yahoo!7 account, in most cases your account will be deactivated and then deleted from our user registration database in approximately 90 days. This delay is necessary to discourage users from engaging in fraudulent activity.
  • Please note that any information that we have copied may remain in back-up storage for some period of time after your deletion request. This may be the case even though no account information remains in our active user databases.

Servers Log Files

  • The Yahoo!7 computers (called "servers") that send your web pages and advertising banners process and store an enormous amount of information every day. These computer records are called “log files”.
  • Log files are used for analysis, research, auditing, and other purposes, as described above. After this information has been used, it is stored and is inaccessible. Until the information is stored, your Yahoo!7 ID may remain in our active server log files.

Anonymisation/de-identification

  • Anonymisation is a process of removing or replacing personal identifiers in data records so that the resulting data is no longer personally identifiable. This is also referred to as de-identification. We use these terms interchangeably.
  • Yahoo!7 uses a multi-step process to replace, truncate, or delete identifiers in order to de-identify data. We are committed to continuous improvements and implementation of our data protection and de-identification measures.

Anonymisation

  • Yahoo!7’s anonymisation policy applies only to search log data.
  • Yahoo!7 stores this data in an identifiable form for up to 18 months.
  • IP addresses within search user log data will be anonymised or deleted within 6 months from the time of collection.
