Customer data is stored for as long as it is needed to provide services, together with contractual legal and regulatory requirements.
Data is retained for the duration of the contract or unless indicated within theMaster Service Agreement (MSA). Data destruction and sanitization is conducted in alignment with the National Institute of Standards and Technology (NIST) Special Publication 800 – 88: Guidelines for Media Sanitization.
In the event of contract termination or deletion request client data is purged within 60 days, from both the primary and secondary Datacenters. In Google Cloud Storage, customer data is deleted through cryptographic erasure. This is an industry standard technique that renders data unreadable by deleting the encryption keys needed to decrypt that data.
