The Sites and Trails app and framework is strongly committed to protecting user privacy.
Whilst specific privacy policies and data collection will vary from site to site, it is a policy of Sites and Trails that your personal information will not be added to 3rd party lists or databases without your express consent.
At the time of writing (July 2015) there are no sites on the system that store personal data beyond that which you contribute as part of a site activity. (i.e. at some locations we may ask about for your name, age, home town and other similar questions.)
Sites and Trails NT does collect your IP address in some circumstances. This information is used to help us identify duplicate or spurious entries that may be submitted to our data sets.
