Instructions on deleting an Eyewire Account

Terms & Privacy Policy

EyeWire mobilizes an online community of volunteers (“EyeWirers”) who map neural connections by playing a game of coloring 3D images of the retina. EyeWirers learn about neuroscience, and discuss the implications of their mapping for the visual function of the retina. Data collected from EyeWirers is used to advance neuroscience research, and also to devise better ways for humans and computers to work together to accomplish challenging tasks. At the same time, EyeWire is committed to preserving the privacy of its members, and fostering a growing community of “citizen neuroscientists.”

Data Deletion

Eyewire stores usernames, emails, and login ids for Facebook and Twitter if you registered your account through them. Instructions are provided if users want to delete their account. You can also contact and we can assist with the account deletion requests. When an account is deleted, all of the previously mentioned data is also erased which means we are not able to restore that account as we have no way to identify the account owner.
