Tracking technologies allow Slack and its partners to build profiles of your behavior across the web, which can affect the ads you see and how your data is shared with third-party advertisers.
Slack collects a wide range of personal data including your messages, files, profile information, location data, and usage patterns, and shares this with service providers, advertising partners, and Salesforce affiliates. While Slack states it does not sell personal data in the traditional sense, it acknowledges that certain data sharing arrangements may qualify as a 'sale' or 'sharing' under California law, which could affect how your data is used for advertising. You can opt out of the sale or sharing of your personal data by visiting Slack's privacy settings or submitting a request at https://slack.com/trust/privacy/privacy-policy.
