We reserve the right to share information to satisfy a legal request, protect people or property, or in connection with a transfer of one or more of our business units.
WHAT INFORMATION DO WE COLLECT ABOUT YOU?
You can visit our websites, read articles and other materials, and check on offerings without giving us any personally identifiable information. So that we can provide our users and subscribers with the most efficient and enhanced, personalized service, we request information about you in certain circumstances, and collect certain information automatically.
We collect personally identifiable information, such as names and/or e-mail addresses, when you register at our web sites or post reviews. Website visitors may register to receive one of our e-mail updates, respond to a survey, or enter online contests and sweepstakes. Registration may be required to participate in message boards, bulletin boards, or chat rooms at our website or to take advantage of special offers. Sometimes registration can be accomplished by submitting only a user name and password. Other types of offerings require submission of additional information. The information we collect may include your e-mail address, name, address, phone number, age, gender, hobbies, family information, and similar demographic information or information related to your interests. Some of our sites may offer you the opportunity to receive offers directly from third parties. Registration forms will indicate what information is required and what information (if any) is optional.
Information Collected Automatically
WHAT DO WE DO WITH COLLECTED INFORMATION?
We use information you provide to fulfill your requests, improve our products and services, and operate our business. For example, we use personal information so that we may display or send custom, personalized content to our website visitors and to send newsletters, e-mails, promotional material, surveys and other updates, information or offers to our users and subscribers. A user may, at any time, opt out of receiving promotional offers by e-mail.
If you wish to subscribe to a newsletter or similar regular informational materials, we will use your name and email address to send the newsletter to you. Out of respect for your privacy, we always provide you a simple way to unsubscribe.
We may produce reports for advertisers, sponsors and vendors containing anonymous, aggregate information about our users and subscribers, such as demographic, age and online usage information. This allows us to provide content and offers that are most relevant to our subscribers and users and to work more closely with advertisers.
HOW DO WE SHARE PERSONAL INFORMATION?
Personal information in the form of names and emails, is available to WhereToGoSkiing, including our technical and fulfillment agents and consultants who make this site and our publications, products and services available to you.
WhereToGoSkiing and its agents may access both anonymous, aggregate demographic data and any personal information you provide for internal marketing or other business purposes, services or products we offer likely to be of interest. Web host firms, technical and database consultants, advertising agencies, and fulfillment firms, including firms assisting us in offering contests and promotions, may have access to personally identifiable information in the course of making our products and services available. All companies working for WhereToGoSkiing must comply with our information collection, use and disclosure policies, and are not permitted to sell your information to third parties or to use it except as authorized by us and you, or as permitted or required by law.
Advertisers, Sponsors and Promotional and Business Partners.
We might share anonymous, aggregate demographic information (such as gender, age, interests, etc.), and anonymous information obtained from cookies and similar technologies, with our advertisers, sponsors, promotional and business partners, and with participating vendors at sites offering online sales opportunities. No personally identifiable information is disclosed to any of these third parties in providing these reports.
We may extend e-mail offers to you on behalf of our business partners about their products or services, but only if you have indicated that you would like to receive such offers. Although WhereToGoSkiing may receive a fee from our business partners for this service, WhereToGoSkiing sends those offers on behalf of the business partner, and does not share your e-mail address with them. Of course, you may opt out of receiving those offers at any time.
At our websites, visitors will also have opportunities to sign up directly with certain advertisers and sponsors to enter contests or sweepstakes, receive e-mail updates, or to receive information directly from them. Third party vendors and advertisers will also use technical and other consultants. We urge visitors to carefully review the privacy policies of these firms. WhereToGoSkiing is not responsible for the privacy policies and procedures of any third party.
You should be aware that if you voluntarily disclose information, personal or otherwise, online in any community area, that information can be collected and used by others. For example, if you use chat, forums, bulletin boards or message boards, or if you post personal information online (such as your e-mail address, photograph, etc.), you may receive unsolicited messages from others.
