The policy for this application states: “We may collect and release Personally Identifiable Information and/or non-personally-identifiable information if required to do so by law, or in the good-faith belief that such action is necessary to comply with state and federal laws (such as U.S. Copyright Law), international law or respond to a court order, subpoena, or search warrant or equivalent, or where in our reasonable belief, an individual’s physical safety may be at risk or threatened.”
The above paragraph is the only information that they give about sharing information of the user. In any case, the only warning it gives is that as long as they are asked by federal law to provide it then they will. I think that although this app is not as prominent in the US as it is in other countries, the service terms are a little simpler because their main market is not based here.
As far as the age of those who use the service I see that this service has a requirement for a minor to be 16-years-old. Whereas other services require to be 13. Although this does not guarantee that minors will be better protected, I think that parents have a little more control over what kind of access they give to their kids to social media.
In the case of the breach of security for their site the only thing they share is that they are not responsible for any of it and will not be held liable for any damage to the user. Although this is not different than other places their policy is self-explanatory.
