When you join the society, you give us information about yourself (your name, your email address, where you work, sometimes an alternative mailing address) which we are duty bound to protect.  As a society, we have always had a strict policy not to share this information, except to give your address to the proceedings publishers (currently The Optical Society of America) so that they can mail your copy to you. OSA are not allowed to use this information for any other purpose. We also email you from time to time about the Society's affairs, particularly in relation to the 2-yearly meeting, and to remind you to renew your membership.  In the past we have also informed ex-members about the next meeting. All this assumed your implicit consent which you gave by joining the society

In addition to your personal details, we store information about when you joined or rejoined, and when you were previously a member.  We also keep track of any ICVS grants you might have received, and what type of membership you have. These data are currently stored off-line on a secure Access database, maintained by the treasurer and not shared with anybody else except as detailed above. 

Due to new European legislation (GDPR), we are now required to seek your explicit permission to use this information in specified ways.  In other words, you need to opt-in to each type of use.  Starting in January 2019, this information will be sought using the on-line membership form.

Note that, if you are registered with listservs such as CVNet and VisionList, you may still from time to time receive emails about ICVS even if you have opted out with ICVS directly.  And of course all information about the society is available on this this website, where you can download Daltoniana, read about forthcoming meetings and renew your membership.
