No cookies/localStorage. Uses FingerprintJS OSS v5 when available; falls back if blocked.
Ready.
Result
server mode: —
device_id (stored)
—
device_id_strict (includes fp visitorId)
—
device_id_coarse (cluster; ignores fp visitorId)
—
Note: Chrome normal vs incognito often changes FingerprintJS visitorId,
so device_id_strict may differ. Compare device_id_coarse
or run the server with DEVICE_ID_MODE=coarse. Also check fraud.minFpId
in the signals table for a very weak cohort key.
