Whenever your data are in transit between you and us, everything is encrypted, and sent using HTTPS. Within our firewalled private networks, data may be transferred unencrypted.</p> <p>Any files which you upload to us are stored and are encrypted at rest. Our application databases are generally not encrypted at rest — the information you add to the applications is active in our databases and subject to the same protection and monitoring as the rest of our systems. Our database backups are encrypted using GPG.</p> Full redundancy for all major systems. <p>Our servers — from power supplies to the internet connection to the air purifying systems — operate at full redundancy. Our systems are engineered to stay up even if multiple servers fail.</p>
