Security Considerations

Calendar Access

10KC’s calendar integration will only work for employees who use the 10KC application and explicitly grant access to their calendars. This integration will not impact any employee who is not a 10KC user.

Data Usage

  • For viewing available times, 10KC uses Google’s freeBusy API which doesn't expose any calendar event data other than when people are free.
  • For creating events, 10KC uses Google’s insert event API which creates calendar events where data is stored in Google Calendar.
  • For reading events, 10KC used Google’s get event API but only for events created by the 10KC application. Moreover, response data from this endpoint does not expose any confidential meeting details.
  • 10KC uses calendar permissions only to optimize the user experience of the members using the 10KC application. 10KC never uses this integration for purposes unrelated to booking meetings.

Security Measures

10KC has strict security policies and we follow all best practices like annual pen-testing, annual internal audit, third party SOC2 audit and aligning with regional data privacy requirements. We take credentials very seriously, only ever using them for signed-in members booking meetings with other members.
