Annex A

Details of Processing

This Annex A describes the details of the processing and serves the purposes of satisfying the requirements of GDPR Article 28.


Subject matter, nature and purpose:


Castor Users are your employees that use the Product. There are two categories of data:


1. Information about Castor Users. This information about Castor Users includes end-user login/registration information for Castor Users as well as metadata about their usage.


2. The Castor Product uses a read-only connection to access the minimum amount of data needed to build your data catalog. To function as planned, it needs to retrieve the following data:

- Data model metadata (Data Warehouse schemas, tables, columns names and descriptions and DBT manifest). Castor does not need access to the Customer’s data itself

- Data Warehouse query logs. These will enable Castor platform to guide users in querying and reading the data. Queries are the only data asset that can contain Personal Data. More specifically in the “WHERE” clauses. It is worth noting that the occurrence of having a Personal Data Point is low and unstructured, given that the said point needs to be explicitly quoted in the query. The said queries (potentially containing personal data) will be retained on Castor’s server only for 90 days in their raw format. A version excluding the personal data may be retained for 365 days.

- Data Warehouse roles and access. These will enable Castor platform to let user know if they have access to given tables of the dataware

- Data Visualization Reports (name, description, users, underlying queries). These will enable Castor users to find relevant reports and understand dependencies with datasets. Castor only needs a read access on these assets


Duration: For the Term of the Agreement.


Data subjects: Customer employees, and where applicable contractors and agents.


Categories of data

Personal data may include any category of personal data, including without limitation:

- Name

- Email address

- Cookie Information

- Device Identifiers, IP-address and other online identifiers - Account log-in details and passwords

- Telephone/mobile number

- Location Data

Cookie information and device identifiers are used to enable login, authentication and service delivery. Location data is used to enable login, authentication and service delivery.

Annex B

Technical and Organisational Measures (TOMs)

1. People

We do reference checks on all our employees and have them sign a confidentiality clause within their contract. All employees must use 1Password with MFA enabled, have their computer disk encrypted, an antivirus installed and auto-lock activated.
We do a yearly company-wide training on security and each development and management tasks, and their relative duties, follow a RACI matrix structure, allowing to segregate the roles of developing, consulting, and validating

2. Physical

Physical access to Castor facilities is protected by individual identification badges, any guest must be invited, welcomed, and accompanied at all time

3. Data

Our data hosting servers are located in Frankfurt, Germany. Data is encrypted in transit with a TLS protocol. Data at rest is encrypted as per this documentation. Only system and tech administrators can access to the data for debugging purposes. All connection to the database are logged.

4. Hosting & Network

We rely on the cloud provider (GCP) networks and authentication with production, staging and testing environments. We encourage our client to use IP whitelisting for Castor


Production environment is totally independent from staging and tests environments with different projects and private networks on GCP and not shared network


Outbound traffic is either channeled through GCP shared static IPs and inbound traffic goes through castor reserved static IP
Only administrators can adjust network rights. We don't allow direct connection to the production cluster and only debug access to developers to some production machines with logging of all connections
Clocks time is being inherited from virtual machine belonging to google cluster which perfom time sync using Network Time Protocol (NTP)

5. Logs

Logs are collected from the application and handled by google cloud logging. Access to the logs is granted by the system administrator and granted to developers only. Google Cloud handles multi zone redundancy for log storage. We retain a maximum of 90 days of logs

6. Availability & Resilience

We have automatic backups of production databases. We also have a replica setup for production databases for fail-over strategy: in case of failures of the leader the follower will take over: high availability on google cloud.
Backup is performed daily automatically and can be adjusted. We target a restoration under 2 hours
We have an administrator on duty who will be warned by monitoring alerts We communicate to customers about such issues and follow a restoration procedure

7. Security audits

We have a yearly pen test and security audit to assess vulnerabilities and an action plan. We also operate a bug bounty program to solicit independent bug and vulnerability reports.
