The current version (v3.6.0-r3) sends nothing anywhere. History below, told honestly. This page mirrors PRIVACY.md in the open-source repository — that file is the authority.
Importing or running this repository's code does not send version numbers, heartbeats, or usage data to any external server. There is no default-on network call-back of any kind.
From commit 0efd980 (2026-08-10) until v3.6.0-r2, one default-on version telemetry existed: on import, a background thread sent the version number and a locally generated anonymous ID to https://effect-anchored-telemetry.zwiserfit.cn/ping (opt-out via EFFECT_ANCHORED_TELEMETRY=0).
Three verified facts about that period:
~/.effect_anchored_anon_id (a UUID v4) in the user's home directory.Any install/usage statistics, if ever introduced, must be: default-off, explicitly asked on first run, field-whitelisted, revocable at any time — and declared in PRIVACY.md beforehand.
