What information is compromised in a data breach?

A security breach of this nature applies to card information only — no personal information linked to card numbers, such as Social Security numbers, PINs, or account numbers, is disclosed.

All the same, this data becomes available to everyone; your data can be used for various things, but most often for advertising offers, tracking your actions.

I feel bad that a lot of my data is publicly available on the Internet. I feel unsafe. Now I want to meet someone on dating sites, and it seems to me that first I should use this online service onerep.com, find and delete all information about me from the Internet, and only then meet someone online.
