Privacy Policy:

Quantum Windows and Doors Inc. ("Quantum") operates www.dev.quantumwindows.ca and may operate other websites. It is Quantum's policy to respect your privacy regarding any information we may collect while operating our websites.

Website Visitors

Like most website operators, Quantum collects non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request. Quantum's purpose in collecting non-personally identifying information is to better understand how Quantum's visitors use its website. From time to time, Quantum may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in the usage of its website.

Quantum also collects potentially personally-identifying information like Internet Protocol (IP) addresses for logged in users and for users leaving comments on www.dev.quantumwindows.ca blogs/sites. Quantum only discloses logged in user and commenter IP addresses under the same circumstances that it uses and discloses personally-identifying information as described below, except that commenter IP addresses and email addresses are visible and disclosed to the administrators of the blog/site where the comment was left.

Gathering of Personally-Identifying Information

Certain visitors to Quantum's websites choose to interact with Quantum in ways that require Quantum to gather personally-identifying information. The amount and type of information that Quantum gathers depends on the nature of the interaction. For example, we ask visitors who sign up at www.dev.quantumwindows.ca to provide a username and email address. Those who engage in transactions with Quantum are asked to provide additional information, including as necessary the personal and financial information required to process those transactions. In each case, Quantum collects such information only insofar as is necessary or appropriate to fulfill the purpose of the visitor's interaction with Quantum. Quantum does not disclose personally-identifying information other than as described below. And visitors can always refuse to supply personally-identifying information, with the caveat that it may prevent them from engaging in certain website-related activities.

Aggregated Statistics

Quantum may collect statistics about the behavior of visitors to its websites. Quantum may display this information publicly or provide it to others. However, Quantum does not disclose personally-identifying information other than as described below.

Protection of Certain Personally-Identifying Information

Quantum discloses potentially personally-identifying and personally-identifying information only to those of its employees, contractors and affiliated organizations that (i) need to know that information in order to process it on Quantum's behalf or to provide services available at Quantum's websites, and (ii) that have agreed not to disclose it to others. Some of those employees, contractors and affiliated organizations may be located outside of your home country; by using Quantum's websites, you consent to the transfer of such information to them. Quantum will not rent or sell potentially personally-identifying and personally-identifying information to anyone. Other than to its employees, contractors and affiliated organizations, as described above, Quantum discloses potentially personally-identifying and personally-identifying information only in response to a subpoena, court order or other governmental request, or when Quantum believes in good faith that disclosure is reasonably necessary to protect the property or rights of Quantum, third parties or the public at large. If you are a registered user of an Quantum website and have supplied your email address, Quantum may occasionally send you an email to tell you about new features, solicit your feedback, or just keep you up to date with what's going on with Quantum and our products. If you send us a request (for example via email or via one of our feedback mechanisms), we reserve the right to publish it in order to help us clarify or respond to your request or to help us support other users. Quantum takes all measures reasonably necessary to protect against the unauthorized access, use, alteration or destruction of potentially personally-identifying and personally-identifying information.

Business Transfers

If Quantum, or substantially all of its assets, were acquired, or in the unlikely event that Quantum goes out of business or enters bankruptcy, user information would be one of the assets that is transferred or acquired by a third party. You acknowledge that such transfers may occur, and that any acquirer of Quantum may continue to use your personal information as set forth in this policy.
