No, Release follows the principle of least privilege - we only require a minimal role on your cloud account for managing and checking out database snapshots. We never need to touch your data and your data never leaves your cloud account.
We currently support AWS. GCP support will be coming soon.
We currently support Amazon RDS and Aurora (MySQL and PostgreSQL). CloudSQL support will be coming soon.
