Privacy and limits

Local-only inputs

The lookup fields and compatibility result stay in your browser and are not sent to the measurement provider. If you explicitly allow aggregate measurement, this page stores that choice in session storage for this tab and may send only named lookup-state events. The provider also receives ordinary request metadata such as IP address, browser/user-agent details, timing data, and provider cookie metadata governed by its policy. There is no account, upload, camera access, address, serial number, photo, or precise-location field.

Not an electrical assessment

The result does not assess wiring, transformer suitability, installation condition, damage, regional electrical rules, or safe operation. It never instructs you to open, remove, measure, bypass, rewire, replace, or modify equipment.

Coverage limits

This first-pass catalog is deliberately small. It covers two Ring doorbell labels and 13 cited chime rows from one US/Canada manufacturer page. Product names and manufacturer pages can change; recheck the linked source before relying on a result.

UNKNOWN is a result

UNKNOWN means the published evidence in this prototype is insufficient or contradictory. It does not mean compatible, incompatible, safe, unsafe, or unsupported.
