GrassrootsPB Privacy Policy


GrassrootsPB is a community effort, and as such we hold the privacy of your data in the highest regard. In light of the community-driven, dynamic nature of GrassrootsPB's development, we will do our best to keep this Privacy Policy up to date with the ever-evolving requirements of making the maximum possible impact. By agreeing to this Privacy Policy, you understand that we may not inform you in advance about any updates we make to it.

Below is a description of what we collect and how it is handled.

Personally Identifiable Information

To participate at GrassrootsPB, an email address and a ZIP code are required. The email address is critical for site function (account activation, password resets, etc.), and may rarely be used for other communication purposes, such as the announcement of major new features, the addition of new candidates, Privacy Policy updates, and calls to action.

ZIP codes are used purely for animating calls on the Live Call Map. We do not verify ZIP codes in any way, so while we encourage users to use their own for accuracy, any valid ZIP code may be chosen! If you're an international user, we suggest you use "00000".

Email addresses and ZIP codes will never be shared with any external entity without first acquiring users' consent via email. Previously, for instance, we've shared consenting users' email addresses with third party benefactors to coordinate prize delivery.

Session Information

Cookies are used for session-tracking and to expose usernames to our call-counting browser extensions. Server logs of IP addresses used to access the site are maintained to investigate and address instances of site abuse.


From all of us on the team, thank you so much for your time and dedication to advancing the progressive cause. If you have any suggestions, concerns, or specific questions, please don't hesitate to contact us! We look forward to working with you in the coming contests!
