Data Categories
What data does Cal.com process?
In typical use, the following data categories arise. Which ones are relevant for you depends on your setup and scope of use.
- Guest name & email address
- Appointment and timezone data
- Phone number (optional)
- Pre-screening answers (lead qualification)
- Calendar sync tokens (Google / Microsoft)
Data Subjects
Who is affected by the processing?
Under Art. 30 GDPR, you must document the categories of data subjects per processing activity. In typical use, these include:
- Applicants booking an interview slot
- Prospects scheduling a demo call
- Clients / patients booking a consultation
- Existing customers scheduling a follow-up
Concrete Impact
What does this mean in practice?
A US authority could theoretically request a list of all persons who have scheduled an appointment with your company, including applicants, clients or patients. The CLOUD Act allows this without involving German courts.
Note: This is a risk description, not a specific incident. Whether access occurred in your case depends on many factors. What can be documented: the risk must be named in your TIA and mitigated with additional measures.
