Privacy Policy

This describes the data handling practices of North Crown Hill for data security and privacy. Last updated 2020-04-23.

Public Data

These data are publicly displayed on the website:

  • The geographic locations of households within the NCH area.
  • The contact status of each household, relative to our outreach effort
    • Examples: Members, Non-members, Uncontacted, Left a flyer...
Our house numbers and locations are already public in greater detail on the King County Parcel Viewer, as well as Google Maps, etc. If you'd like your house or status changed or removed, please send an email request to

Private Data

These data are, when shared with organizers, recorded and kept internal to only the core organizer(s) of NCH:

  • First name(s)
  • Email address
  • Phone number
  • True/false status of participation in:
    1. email newsletter
    2. neighborhood chat
    3. phone hotline
  • Short notes about interactions, context, status
This information is kept confidential, and is not shared with neighbors except under the explicit request of the sharer. Last names are deliberatly excluded from recording, as they are unneeded.

Email and Slack data handling

No email leakage via mass direct emails or mass BCCs: The newsletter uses Mailchimp to enforce industry-standard practices for email privacy. No newsletter recipient can discover any other recipient's email. Every newsletter contains an unsubscribe link.

Slack is configured to hide users' email addresses. Only residents with verified house addresses in our boundary area are sent invites. No mass/open invites allowed, and members may not invite others without admin approval.

Privacy Recommendations for Residents

  • Our total neighborhood size is approximately 350 households. Think about your trust level at that size.
  • It is common practice to share one's house address in Slack, but if that feels risky for you, please abstain.
  • There's no need to use your last name in Slack.
  • Your profile picture in Slack doesn't need to be be "real" or contain identifying information.
  • Message editing and deletion are enabled, so if you feel you've overshared, you can redact the chat record.
  • Slack channels are visible to all members, even if they are not currently "in" that channel. If you'd like to share contact information with specific people, use a Direct Message instead of posting in a channel.
  • Administrators can not see or export your private messages. Please report any harrassment or abuse ASAP to
