Client-side encryption for Google Calendar is now generally available on mobile

What’s changing

Earlier this year, we expanded the client-side encryption beta to Google Calendar on mobile to help customers strengthen the confidentiality of their data while helping address a broad range of data sovereignty and compliance requirements. Today, we’re happy to announce that client-side encryption for Google Calendar is now generally available on Android and iOS devices for eligible Workspace editions. 

When using client-side encryption for Calendar events, your event description, attachments, and Meet data is encrypted before it reaches Google servers. You have control over encryption keys and the identity service to access those keys.

Who’s impacted 

Admins and end users 

Why it’s important 

Google Calendar uses strong cryptographic standards to encrypt all data at rest and in transit between its facilities. With client-side encryption, your organization has control of encryption keys and the identity provider (IdP) used to access those keys to further strengthen the security of your events data.

Client-side encryption helps you to create a stronger privacy posture, whether that’s to help your organization comply with regulations like ITAR and CJIS or simply to better protect the privacy of your confidential data. 

Getting started 

  • Admins: 
    • This feature will be OFF by default and can be enabled at the domain, OU, and Group levels. Go to the Admin console > Security > Access and data control > Client-side encryption. Visit the Help Center to learn more about client-side encryption
    • If you have already configured CSE for Web, you will still need to add client IDs and redirect URLs for your Android and iOS clients in order for end users to access this feature on their mobile devices. 
  • End users: 
    • You will need to be logged in with your Identity Provider to have access to encrypted content. 
    • To add encryption to any event in Calendar, click on the shield icon at the top of the event creation card. This will add encryption to the event description and the Meet video conference, and enforce encryption on event attachments. Other items such as event title, time, and guests remain on standard encryption.
