A second switch under System > Usage stats, "Also send anonymous error
counts", or `BULWARK_TELEMETRY_ERRORS=on|off`. Off by default, off
whenever the heartbeat is off or no third-party traffic is on, and
switching the heartbeat off switches it off too. With it on the
heartbeat becomes schema 2: the v1 fields unchanged plus `errors`, up to
50 fingerprints of the last complete UTC day with the error name, the
top frames in Bulwark's bundles (path, line, column, debug ID), the
version, a bucketed count, on how many of the last 7 days it occurred,
and a message only when it is a fixed error code. Without the consent
the heartbeat stays exactly schema 1. The admin preview shows the v2
payload as soon as the switch is flipped.
Adds a once-per-day heartbeat that lets the project see how many
instances run Bulwark, on what platforms, with what features enabled,
and roughly how many accounts they have. No email addresses, hostnames,
IPs, or any end-user data are ever sent.
- lib/telemetry: state file, payload builder, jittered scheduler,
instance_id persistence at <data-dir>/.telemetry-id (delete to reset)
- app/api/admin/telemetry: admin API for status / set-consent /
set-endpoint / send-now (all audit-logged)
- app/admin/telemetry: settings page with status, JSON payload preview,
endpoint editor, send-now button, link to the privacy page
- instrumentation.node.ts: starts the scheduler on boot
Default state is enabled. The first heartbeat fires 1 hour after boot
so an admin who installs and immediately disables produces zero pings.
Disable via the settings UI, BULWARK_TELEMETRY=off (or
BULWARK_TELEMETRY_DISABLED=1), or by clearing the endpoint.
Account counts are bucketed (1, 2-5, 6-10, 11-50, 51-200, 201+) so a
small instance can't be re-identified by exact size. The /.telemetry-id
file can be deleted to mint a fresh instance_id.
Receiving collector is open source at bulwarkmail/dashboard. Self-host
your own and point at it via BULWARK_TELEMETRY_URL. Full schema,
retention (90d raw → aggregates), and lawful basis are documented at
bulwarkmail.org/docs/legal/privacy/telemetry.
