Our Mission

Circadian Sleep Disorders Network is an independent nonprofit organization dedicated to improving the lives of people with chronic circadian rhythm disorders.

We aim to increase awareness within the medical community and among the general public, to provide emotional support and practical ideas for people living with these disorders, to inform patients and health care providers about treatment options, to encourage research into circadian rhythms, and to advocate for accommodations in education and employment for people with circadian rhythm sleep disorders.

Organization

We are a 501(c)(3) organization based in the U.S., serving the global circadian sleep disorders community. We are a patient organization, entirely supported by member dues and contributions.

We are an all-volunteer organization. None of the board members or officers is being paid. We are using our funds for expenses, such as the cost of applying for tax exempt status, printing costs, web costs, etc.

We see this as an international endeavor. While initially most of our activity will occur in the U.S., the information on our web site is available world-wide, and our brochures will be useful to English-speakers everywhere. The research we encourage will be useful world wide. In the future we hope to sponsor affiliated groups in other countries.

Our Board of Directors

All our directors and officers are volunteers. We are not paid for our work.

Some History

Around 1996 Wendi Dunlap started an email list at circadiandisorders.org/list for people with Circadian Rhythm Sleep Disorders. The list has grown to over 800 members, primarily people with DSPS or Non-24 or their family members. Some people on the list felt we needed a more formal organization to promote awareness of CSDs, and to advocate for accommodations. Peter Mansbach, James Fadden, and Beth Macdonald got together and started Circadian Sleep Disorders Network. We incorporated on August 18, 2011, and opened to membership on January 1, 2012.

We quickly set up a web site, adopted bylaws, expanded the Board of Directors, elected officers, set up finances and accounting, defined membership, integrated dues payments with PayPal (you can write a check instead, if you prefer), applied for and received tax-exempt status in the U.S., and filed tax returns. We formed a Medical Advisory Board, expanded the web site, and formally affiliated with the Niteowl Email List.

We have established a patient registry and survey, which is ongoing. We found interesting (and surprising to some) results from the survey, and are in the process of getting them published. We developed a Needed Research document as input to an AASM/SRS/SRBR White Paper.

We have established a presence on various social media, and persuaded NIH (U.S. National Institutes of Health) to include Circadian Rhythm Sleep Disorders on the sleep-related pages of its website. We have spoken about our disorders at various conferences, been interviewed on the radio and for magazines, and lobbied Congress for more sleep research funding.

We are developing programs and strategy, and embarking on the goals in our mission. There's still a lot to do! Some current activities are reported in the News section of our Home Page.

Privacy Policy

GDPR

The General Data Protection Regulations (GDPR) took effect in the European Union, and covers our EU members. We have always repected our members' privacy, and our use of member data has not needed to change. We are clarifying our privacy practices, as required by the GDPR. These practices apply to all our members, not just those in the EU.

What information do we collect?

We are not requiring members to provide any more personal information than they are comfortable providing. However, if you did not give us a valid email address, we would not be able to contact you at all, so we do require that. We ask for but do not require home address for future use if we go to printed newsletters, or to select people to invite to local support groups near them if/when we start.such groups.

If you pay using PayPal, only PayPal gets your payment data (bank account or credit card). We never see this information. We can view the name and email address you provide to PayPal, and in some cases the street address as well, but we will not make use of this. You may also pay by check. We will not retain any bank data from the check once it has been deposited and the deposit has been accepted.

How do we use your personal information?

In keeping with the principles set out in the GDPR, we at Circadian Sleep Disorders Network will use your email address, your name, and your address to keep in touch with you, based on what the regulation details as "legitimate interest".

We use your membership data to send email newsletters, other occasional items of interest, and renewal reminders. We do not send advertising for any other organization or company. In the future we may decide to send hard copy newsletters by postal mail.

We expect to send renewal reminders and perhaps some especially important news notes for three years after your membership lapses. After that, we will stop sending you email.

When we start local support groups we may extract email addresses of people in the vicinity, in order to notify them.

Who can see your personal information?

We take your privacy seriously. We understand that you may not want your membership in Circadian Sleep Disorders Network to be public information, and we take every precaution to keep your data private. We will never sell or give away our membership information. That promise is enshrined in our bylaws!

Our membership list is private, and only accessible by the few people with a need to know. Currently, that is the president, vice president, secretary, treasurer, and newsletter editor, since they need to process your membership dues, email the newsletters and election ballots, etc. If in the future they are assisted by other individuals, those others may be given access to membership information, but only by explicit vote of the Board of Directors.

What other companies receive your personal information?

Your right to be forgotten

If you want your personal data to be removed entirely (the "right to be forgotten"), you may request that by sending email to , and we will remove your personal information from our database (in Google Docs) and from MailChimp. For accounting purposes we need to retain your payment history, but it will no longer be connected with a name or other identifying information. We cannot remove email addresses from previous elections from the election-processing host. We cannot remove information from PayPal.

Registry and Survey

We have created a patient registry and survey in partnership with Invitae Corp, and strongly encourage our members to register and to participate. The personally identifying data you provide is between you and Invitae, the registry hosts. We at Circadian Sleep Disorders Network do not see any personally identifying information in conjunction with the data. We do have access to your answers to the survey questions, but without knowing who those answers are associated with. If you explicitly allow Invitae to share your email address with us, they do so, but that is completely separate from the survey. We cannot connect your email address with your survey answers.

The privacy of your personally identifying information is determined by Invitae. They agree to abide by HIPAA regulations (U.S.) and GDPR (E.U.). You may request deletion of your data from Invitae, and your personal information will be deleted, but any de-identified data that is already in process of being analyzed can not be recalled.

Niteowl Email List

The previous maintainer of the Niteowl email list has retired, and the host computer is no longer operational. Sorry.

If someone wants to volunteer to set up and run an email list, please co-ordinate with us at .
