In addition to our belief in the importance of trust and transparency, as outlined here and in our policies, we believe in the importance of fundamental privacy protections, legal safeguards and judicial oversight of government data collection and surveillance.
- We are committed to maintaining Customer privacy and confidentiality
- Every request is carefully reviewed to ensure there is a valid legal process
- All requests will be interpreted narrowly by Slack
- Wherever possible, we encourage Customers and third parties to seek data without our intervention
