This privacy notice discloses the privacy practices for the odop.springdesignsoftware.org website. This privacy notice applies solely to information collected by this website. It will notify you of the following:

Information Collection, Use, and Sharing

We are the sole owners of the information collected on this site. We only have access to/collect information that you voluntarily give us via email or other direct contact from you. We will not sell or rent this information to anyone. We will use your information to respond to you, regarding the reason you contacted us. We will not share your information with any third party outside of our organization, other than as necessary to fulfill your request, e.g. to ship an order. Unless you ask us not to, we may contact you via email in the future to tell you about new products or services, or changes to this privacy policy.

Your Access to and Control Over Information

You may opt out of any future contacts from us at any time. You can do the following at any time via Contact Us:


Where possible, we avoid collecting sensitive information (such as credit card data). We take precautions to protect any information we do collect. If you do submit sensitive information via the website, your information is protected both online and offline. You can verify this by looking for a lock icon in the address bar and looking for "https" at the beginning of the address of the Web page. While we use encryption to protect sensitive information transmitted online, we also protect your information offline. Only personnel who need the information to perform a specific job (for example, billing or customer service) are granted access to personally identifiable information. The computers/servers in which we store personally identifiable information are kept in a secure environment.


This website contains links to other sites. Please be aware that we are not responsible for the content or privacy practices of such other sites. We encourage our users to be aware when they leave our site and to read the privacy statements of any other site that might collect personally identifiable information.


A "cookie" is a piece of data stored on a site visitor's local storage to help improve the visitors access to that site and identify repeat visitors. For instance, by using a cookie to identify you, you would not have to log in a password more than once, thereby saving time and effort. Cookies can also enable a site to track and target the interests of its users to enhance the experience on the site.

The odop.springdesignsoftware.org website does not use cookies. However, some of our business partners (for example: Okta, Heroku, JawsDB, GitHub Pages, Gartner / Capterra and Google Analytics) may use cookies related to our site. We have no access to or control over these cookies.

The ODOP AutoSave feature utilizes a technology similar to cookies in order to preserve and recover design data in various situations where it might otherwise be lost. This AutoSave feature is not used for user tracking.

IP Address

In addition to the previously mentioned features of Okta, the Okta logs provide IP address information associated with user sessions. Also, we collect user IP address information associated with access to our database (a.k.a. the ODOP Design Library) for the purpose of measuring usage of the system. Google Analytics is currently under evaluation as an alternative means to measuring usage of the system that does not reveal IP address information. Note that use of VPN (Virtual Private Network) technology hides the true IP address and physical location of the user.

**Public Account
Evaluators may sign-in with the username "public" and password "public". It is possible to save designs into the public account but keep in mind that all saved information will be completely public.

If you feel that we are not abiding by this privacy policy, please Contact Us immediately.
