Subprocessors
The list

Information held in the United States may be accessible to its courts, law enforcement and national security authorities under its laws. Each provider is bound by contract to use the information only to provide its service to us. The Privacy Policy says more about what each one receives.
What isn’t on the list
ParagonBooks doesn’t connect to banks. Bank transactions come in only as files you import.
If you turn on notifications, your browser’s own push service delivers them. The browser chooses the service, and the notice is encrypted so only your device can read it.
When you send an invoice, share a report or connect your own tools through the API or MCP, the information goes where you send it. Those recipients aren’t our subprocessors.
Changes to this list
When we add or replace a subprocessor, we update this page and its effective date first. If a change sends your information to a new company or a new country, we will tell you by email and in the app before it takes effect. Questions go to our Privacy Officer at hello@altumo.com.
