1. May 6, 2026  List update  
### Subprocessor list refreshed and standardized  
The subprocessor list at /legal/subprocessors/ was refreshed and brought into alignment with the DuoCircle Cloud Terms and DPA published the same day. No new subprocessors were added in this revision; vendor categories, headquarters, and roles were updated for accuracy. The standing thirty-day notice window applies to any subsequent additions.
