Ordinary matching

Matching uses downloaded identifiers in the browser. It does not require uploading each encountered account or page.

Requests you choose

Opening evidence, using online alternatives and submitting a report contact this service. Cause-specific downloads can reveal which dataset you requested. Your IP address is necessarily visible to the server/network delivering it.

No invented anonymity promises

This application adds no advertising analytics. Hosting/proxy access logs depend on the deployment configuration and need a retention policy before public launch. Local overrides are not sent as telemetry.
