But :
"About us" (http://www.taste.io/about): There is nothing about you...
You ask people for their names, email addresses and/or to link to their facebook accounts but you don't return the courtesy of identifying yourself or your company.
You make some promises and cite some laws about privacy (http://www.taste.io/privacy-policy) but if you don't say who you are, we can't even be sure that those apply to you...
The "Privacy" page gives a hint. It gives a contact address of "contact@ymal.io". "ymal.io" just redirects back to "taste.io". But WHOIS gives some info for "ymal.io". It's registered to [redacted].
That location is a 5-story building, but the most likely location is Spark Labs, which is a co-working space.[1] $550 a month for a desk. And, yes, "ymal.io" is listed as a member of Spark Labs.[2] So, if you need to find them, that's where to look.

If they are really hosted in Sweden, does the collected data is under Swedish law and not US as mentioned on privacy page ?
"In addition, all sensitive/credit information you supply is encrypted via Secure Socket Layer (SSL) technology.
We implement a variety of security measures when a user enters, submits, or accesses their information to maintain the safety of your personal information."
I really like the service, but it's free to get https setup and takes just about 0 effort thanks to letsencrypt.
