Notice of changes

In short

We tell workspace owners 30 days before a new provider starts handling customer data.

We will not let a new sub-processor handle customer data without giving at least 30 days' notice by email to workspace owners. This page is updated first, and its date above shows when the list last changed.

Each provider is bound by its own data-processing agreement with us. Questions about this list go to privacy@shortzen.io.
