Data handling

Keeping data safe
and telling you
how it’s used.

The data our customers put on the Internet is a part of our customers themselves. We want customers to know that the data they’ve entrusted with us will be kept completely secure.

Any data from our customers is defined as personal data and, as such, is handled with the utmost care as well as the most comprehensive of security measures. We always make sure your privacy is respected whenever we use your data and inform you exactly what purpose it’s being used for.

Data settings

Change how much data you share,
and the way it’s used.

Our customers’ data is a part of our customers. We will never try to force customers to provide information by telling them it “benefits everyone”.

What is important to us is that customers always have the final say in how much data they share and in what ways it’s used. Yahoo! JAPAN provides users with an easy way to check and adjust their personal data. Make sure to check your current settings and make any adjustments as needed.
