In addition to our commitment to trust and transparency, we also believe in the importance of fundamental privacy protection of user data, constitutional guardrails and judicial oversight of government data collection and surveillance.
We abide by the following Guiding Principles:
- We are committed to maintaining Customer privacy and confidentiality.
- All legal process is carefully reviewed. Slack rejects or challenges any requests that have no legal basis or are unclear, overbroad, or otherwise inappropriate.
- Slack construes legal process as narrowly as possible.
- Wherever possible we encourage Customers and third parties to obtain relevant data without our intervention.
