Your privacy and security

Calendly is a cloud application that provides meeting scheduling as a service. Our platform creates a seamless experience to schedule meetings through securely integrating with calendar providers to check availability. Calendly applies best security practices retaining a minimal amount of customer data and operating with the fewest privileges necessary to provide a great experience.

When using OAuth calendar integration, Calendly does not require any access to customer computing resources. When using the Calendly Outlook Plug-in, Calendly requires installation on computing resources to read calendar conflicts and schedule events.

Calendly’s commitment to trust

Customer trust is critical to everything we do at Calendly. Our software is designed to request the most limited access to customer resources to achieve a seamless scheduling experience. We never store any of your calendar details. We are continuously mindful of our customer’s privacy and limit access to all customer data on a need to know basis internally. Our employees are given security training during on-boarding and access to internal systems is further protected by multi-factor authentication.

Physical infrastructure

The Calendly application is hosted on Kubernetes / Google Cloud Services (GCS). GCS' data center operations have been accredited under:

  • ISO 27001
  • SOC 1 and SOC 2/SSAE 16/ISAE 3402 (Previously SAS 70 Type II)
  • PCI Level 1
  • FISMA Moderate
  • Sarbanes-Oxley (SOX)

PCI compliance

Calendly uses Stripe, a PCI-compliant pay processor for encrypting and storing credit card details. More information on Stripe’s commitment to security and compliance can be found here. We utilize the direct Stripe javascript integration, so your credit card information never reaches Calendly’s servers.

Customer security best practices

We avoid collecting third-party passwords by utilizing OAuth authentication with Office365 and Google Calendar.

Data Encryption:

  • All connections from the browser to the Calendly platform are encrypted in transit using TLS SHA-256 with RSA Encryption.
  • All data is encrypted when written to disk.
  • User passwords are stored as salted password hashes and never accessible by any Calendly employee.

Is Calendly GDPR compliant?

Calendly is committed to General Data Protection Regulation (GDPR) compliance. We understand the importance of incorporating standards put forth by the GDPR into our data practices and making sure our customers, whether citizens of the EU or businesses that use Calendly with European customers, feel secure and confident to continue using Calendly. We have developed new features, enhanced existing functionalities, and established additional documentation regarding our efforts.

Calendly has designed its data privacy program to be compliant with GDPR, both now and as future developments come along.

In response to the new data protection rules for EU customers based on the General Data Protection Regulation (GDPR), which went into effect on May 25, 2018, we have updated our Terms of Use and Privacy Policy. There is no action required on your part, and the changes should not affect the way you use Calendly. Here are a few of the highlights of the security changes:

  • More clarity and data transparency: We simplified language around the information we collect from our customers and how it is used, along with explanations of your choices for controlling personal information in the Calendly platform.
  • GDPR: The GDPR gives EU citizens more control, choices and rights over how their data is used and puts forth guidelines for the collection and processing of data for businesses. We’ve created a Data Processing Addendum that reflects the new GDPR standards and states how we hold ourselves to these standards as a business.

If you integrate Calendly to share invitee information with another application, we designate invitees in GDPR countries as "transactional contacts" so their information is only used to send information about orders, shipments, test message, etc., unless they explicitly opt-in to future, marketing-related emails.
