About Shamar Shield

Shamar Shield is a shared watch over the places our community lives, learns, and prays.

Antisemitic incidents are reported in scattered places: police blotters, local news outlets, and the group chats and listservs where neighbors tell each other what happened. By the time the information reaches the people who need it, it usually arrives late, incomplete, or not at all. Shamar Shield gathers those reports into one map and one feed, then ties them to the addresses you actually care about, so an alert arrives when something is reported near home, near a child's school, or near the synagogue your family attends.

Shamar Shield is for individuals and households who want to know what is happening in their own neighborhood, and for the institutions that carry responsibility for a community — synagogues, day schools, community centers, camps, federations, and volunteer security groups. An individual keeps a private watchlist of saved places with their own alert radius. An organization registers its facilities, invites the staff who should be watching, and receives an email when a report lands inside the radius around one of those facilities. Families on a household plan can also see where their members are and be warned when someone is close to a recently reported incident.

Trust matters more here than volume. Every record shows its source and whether it is verified, community reports are published in good faith but labeled unverified until a moderator reviews them, and the app is explicit that it is not an emergency service — if someone is in danger, call 911. Shamar Shield is built and maintained by a small independent team that works alongside community security volunteers, and a portion of subscription revenue is pledged to Jewish security causes.

Built around places, not headlines

You add the addresses that matter — home, work, a school, a synagogue — and set how far around each one counts as nearby.

Every report says where it came from

Official crime data and news media are labeled as such. Community reports publish immediately but stay marked unverified until an admin reviews them.

Made for households and institutions

Individuals keep a private watchlist, families share location with a plan that covers the whole household, and institutions monitor their own facilities with their staff.
