Subprocessors

GRID relies on the third parties below to deliver specific parts of the service. Each has its own Data Processing Agreement accepted by GRID; the table notes what data category each processor sees and where they're hosted. If you're in the EU/EEA and exercising a right-of-access, this is the authoritative list as of the page footer date.

When this list changes

When we add, remove, or replace a subprocessor in a way that could reasonably concern a user (e.g. a data-category or regional change), we update this page and bump the policy version recorded in every new user's consent log. Users are prompted to re-accept the Terms on their next sign-in. If you have a pending DPA signature with GRID, we notify you 30 days before the change takes effect.

Objecting to a subprocessor

Enterprise customers may object to a new subprocessor within 30 days of notice by emailing privacy@grid.systems. Individual users exercising Art. 21 right-to-object may either disconnect the relevant integration (where provider-specific) or delete their account.
