## Privacy

MIT OpenCourseWare respects your privacy. We do not collect personally identifiable information about you unless you voluntarily provide it, such as when you provide email contact information to subscribe to the OCW newsletter, send feedback to OCW, or respond to a survey. If you voluntarily provide your email address or other contact information, we might also use it to inform you of changes to OCW, to survey you about your use or opinion of OCW, or to ask for your support. At your request, we will remove your contact information from our files.

We do not make your contact information or any other personally identifiable information available to anyone outside OCW or its service providers (who use the information only for authorized OCW purposes) unless we are legally required to do so.

In addition to the above, we collect certain anonymous (non-personally identifiable) information to help us improve the OCW web site and to evaluate the access and use of OCW materials and the impact of OCW on the worldwide educational community:

- We collect information you provide about your use of and satisfaction with OCW through email you send us, through the OCW feedback form, and through OCW surveys, whether or not you voluntarily include your contact information.
- We may use web analysis tools that are built into the OCW web site to measure and collect anonymous session information.
- We also use "cookies" to improve your OCW web experience and to collect anonymous information about how you use OCW. However, cookies are not required for OCW use. If your browser is configured not to accept cookies, you will still be able to access OCW and its content.

When we report information about OCW access, use, and impact, we report aggregate, non-personally identifiable data. Occasionally, we report quoted feedback from users. We do not attribute feedback to specific individuals unless we obtain permission to use that person's name along with the feedback.

## MIT Interpretation of "Non-commercial"

Non-commercial use means that users may not sell, profit from, or commercialize OCW materials or works derived from them. The guidelines below are intended to help users determine whether or not their use of OCW materials would be permitted by MIT under the "non-commercial" restriction. Note that there are additional requirements (attribution and share alike) spelled out in our license.

1. Commercialization is prohibited. Users may not directly sell or profit from OCW materials or from works derived from OCW materials.
   Example: A commercial education or training business may not offer courses based on OCW materials if students pay a fee for those courses and the business intends to profit as a result.
2. Determination of commercial vs. non-commercial purpose is based on the use, not the user. Materials may be used by individuals, institutions, governments, corporations, or other business whether for-profit or non-profit so long as the use itself is not a commercialization of the materials or a use that is directly intended to generate sales or profit.
   Example: A corporation may use OCW materials for internal professional development and training purposes.
3. Incidental charges to recover reasonable reproduction costs may be permitted. Recovery of nominal actual costs for copying small amounts (under 1000 copies) of OCW content on paper or CDs is allowed for educational purposes so long as there is no profit motive and so long as the intended use of the copies is in compliance with all license terms. Students must be informed that the materials are freely available on the OCW Web site and that their purchase of copied materials is optional.
   Example: An institution in a remote area has limited Internet access and limited network infrastructure on campus, and a professor offers to create CDs of OCW materials relevant to her course. The professor may recover the costs of creating the CDs.

If you have questions about acceptable use of OCW materials, please contact us.
