Terms and conditions for a website seem like overkill. One party composes said site, another party reads it. How could it get all complicated?
YosemiteHikes.com uses third party advertisements to support the site. Some of these advertisers may use technology such as cookies and web beacons when they advertise on the site, which will also send these advertisers (such as Google through the Google AdSense program) information including your IP address, your ISP, the browser you used to visit the site, and in some cases, whether you have Flash installed. This is generally used for geotargeting purposes (showing New York real estate ads to someone in New York, for example) or showing certain ads based on specific sites visited (such as showing cooking ads to someone who frequents cooking sites). Google has also introduced something they call "interest-based advertising", which means that they'll try to store cookies from any sites you visit that have Google-affiliated ads on them, so that they can serve you ads based on what they think your browsing habits tell them about your interests. This, alas, is an opt-out rather than an opt-in program, and you have to visit this website to opt out of Google's program.
YosemiteHikes.com also uses analytics software to keep track of visitor counts, pages visited, and a variety of other statistics. Though the analytics software doesn't offer up visitors' IP addresses in its reports (at least as far as I can tell), it will keep track of how many visitors from a particular city have visited the website and general information like how long their visits lasted. In addition, the web hosting company for this website stores standard log files for the site, which include records of which pages are visited by each visitor's IP address.
This website doesn't sell any of your personal information to third parties. If you send in an email, for instance, your email address won't get sent on to a spam farm. Quite frankly, you're lucky if I can get it together enough to even reply.
While we're on dull legal subjects, I'd like to point out that you use this website at your own risk. Although yosemitehikes.com attempts to provide accurate information, it's always possible that there are mistakes here or there; in addition, conditions in the Yosemite area are beyond the site's control and could change at any time, and you're responsible for your own actions and personal safety when you're visiting. If the hotel you wanted to stay in is full or an earthquake has rendered a yawning chasm across what this website has described as a safe trail or your toast was burned this morning (just to provide a few non-comprehensive examples), it's up to you to use your own undoubtedly excellent judgment to stay safe and happy, and not hold this website responsible for anything that goes amiss. Though everyone associated with yosemitehikes.com, and probably lots of people who aren't, personally wish you nothing but the best.
