Безопасен ли spring-tns.net?

I don't know more than that it's some kind of analysins service for websites, and like all of them it does tracking and shares user information to third parties. Personally I consider just that to be enough for me to not trust the service, and I feel that it's a reason for caution with children - although this is almost 100% unavoidable in web, it doesn't make it acceptable for me.
