Fields sent
When the browser error beacon is enabled, it may send the error message, source, page path, line number, and user-agent string. The endpoint truncates message, source, page, and user-agent fields before relay. It is designed not to receive passwords, API keys, memory bodies, cookies, or authentication headers.
Do not put secrets in browser errors. A thrown exception or custom error message can contain information supplied by a page or extension. The beacon is bounded, not a guarantee that arbitrary browser error text is harmless.
Limits and destination
- requests are accepted only from the public Perseus origin allowlist;
- the request body is capped at 4 KiB;
- each source IP is limited to 20 records per rolling minute; and
- the API relays accepted records to the operator-controlled notification service when configured.
If the relay is unavailable, the page does not retry indefinitely and the error record may be dropped.
Opt out
Set localStorage key perseus-telemetry to off before browsing the site, or use the control below. The setting is local to that browser profile.
What this is not
This is not product-usage analytics, a session recording, an advertising tracker, or a substitute for the Cloud privacy policy. Authenticated Cloud request logging and billing records are covered by the service boundary, not by this browser beacon.
