Per the company's User Privacy Policy, paragraph 3, located at https://www.miltonscraftbakers.com/userprivacy:
How we store your personal information.
When you provide us with your name and contact information, they are automatically recorded in a Windows server operating environment via an SQL database using an Always Encrypted Database Engine that is owned and managed by Milton's. On rare occasion, user contact information may be stored via an offline datastore (i.e., paper) and within a locked facility and only accessible by Milton’s staff. Every 90 calendar days, this offline datastore is evaluated and all records no longer in active use are shredded via an in-house cross-cut DIN Level 3-4 or better shredder. Technical infrastructure security is managed, updated, and maintained via a third-party IT Support and Cybersecurity NIST compliant firm located in San Diego, CA.
