Trick-or-Treat Safety Check

Check an area before you go. Free look-up, no account, nothing saved on a server.

PROTOTYPE — TEST IT & TELL US WHAT'S MISSING

1 · Check an area

Enter the address or ZIP where you'll trick-or-treat, a grandparent's house, a babysitter's street — anywhere kids will be.

3 · Build your night: planned stops

Add each street or house you plan to visit. We'll check a tight ¼-mile circle around each one and flag the ones that need an official-registry double-check before you knock.

🟠 Flagged = the data returned a count near that stop — look it up on the official registry and decide your route. 🟢 No count returned ≠ “safe.” Data can be incomplete or out of date. Your eyes still matter most.

4 · Walk Mode PREMIUM PREVIEW

Keep this page open while you walk. If your GPS gets close to one of your flagged stops, your phone buzzes and beeps. In the paid app this works with the phone locked — in a web prototype it only works while this page is open and on screen.

Walk Mode is off.

Halloween basics (South Carolina)

  • SC probation/parole runs a Halloween curfew — 5:30–9:00 pm on Oct 31 — for supervised offenders whose crime was against a child: lights off, no candy, stay inside. That covers only people still under supervision, not everyone on the registry.
  • A dark house with no porch light is a skip anyway — that's the universal signal, registry or not.
  • Adults walk with younger kids. Stay on lit streets. Phones charged.
  • Check the route before Halloween night, when you can think — not at the curb with kids in costume.

What Premium would add

  • Exact house pins with name, photo and official record link (paid data license)
  • Background pings — phone locked, app closed, it still buzzes you
  • Saved places (home, school, sitter) + an alert if someone new registers nearby
  • Route planner that builds your trick-or-treat walk around flagged houses

Prototype pricing idea: free look-up forever · Premium ~$4.99/mo, or a one-time Halloween pass.

Honest disclaimer: This is a prototype built for testing an idea — not an official safety tool and not affiliated with any law-enforcement agency. Counts come from the free anonymized Offenders.io data feed, which aggregates public registries; records can be incomplete, delayed, or wrong, and a “0” never guarantees an area is safe. Verify anything that matters on the official registries linked above. Registry information must never be used to harass, threaten, or harm anyone — that is illegal. Addresses you type are sent only to OpenStreetMap (to find them on the map) and are not stored on any server; your planned stops are saved only in this browser on this phone.
