Slack has turned your private messages into AI training data without your explicit consent, raising serious privacy concerns. - Author: Dr Mark van Rijmenam, CSP - Tags: News, #seo-post-1 Did Slack just overstep the [privacy](https://www.thedigitalspeaker.com/data-privacy-speaker/) line by using your data to train AI models? Slack has turned your private messages into AI training data without your explicit consent, raising serious privacy concerns. In a startling revelation, Slack has admitted to using customer data—including private messages, files, and other content—for training its AI and machine learning models. By default, this data scraping happens without requiring users to opt-in, leaving many feeling blindsided by what they perceive as a massive breach of trust. This discovery has set off a firestorm of criticism from users and corporate administrators alike. Despite [Slack's assurances](https://slack.com/intl/en-au/blog/news/how-slack-protects-your-data-when-using-machine-learning-and-ai?ref=thedigitalspeaker.com) that technical controls prevent access to the actual content of messages and files, the realization that such data could be leveraged for AI training has many scrambling to opt out. The opt-out process itself has been criticized for its complexity, requiring workspace owners to send specific email requests to Slack’s customer experience team, which places the burden squarely on the users rather than the company. The crux of the issue lies in the invasive nature of the data collection. Even though Slack claims the data is de-identified and aggregated, the fact remains that sensitive information from direct messages and other private channels has been used without users' explicit consent. This approach raises significant ethical and privacy concerns, particularly in an era where data breaches and privacy violations are increasingly scrutinized. Corporate administrators and CISOs (Chief Information Security Officers) are particularly vocal about their discontent. They argue that while it is not uncommon for big-tech vendors to leverage user data for AI development, the onus should not be on customers to opt-out. Instead, Slack should have implemented an opt-in system, ensuring users are fully aware and agreeable to their data being used in such a manner. Slack’s response to the backlash has been to emphasize that its generative AI products, which rely on large language models (LLMs), do not use customer data for training. They insist that all data used for traditional machine learning models is handled in a privacy-protective manner, with measures in place to prevent any leakage across workspaces. However, this reassurance [has done little](https://humenglish.com/technology/slack-under-fire-for-using-user-data/?ref=thedigitalspeaker.com) to quell the concerns of many users who feel their privacy has been compromised. The broader implication of Slack’s actions touches on a fundamental principle: the right to control one’s personal data. As AI continues to advance and integrate into various platforms, the need for transparent and ethical data practices becomes ever more critical. Users must be empowered with clear, straightforward options to consent to or decline the use of their data. Anything less undermines trust and could have long-lasting repercussions for user confidence and corporate reputation. So, how should companies balance innovation with privacy? Can transparency and user consent coexist with the drive for advanced AI capabilities? These are questions that need addressing as we navigate the future of data-driven technologies.

Slack has admitted to using customer data—including private messages, files, and other content—to train its AI and machine learning models. This happens by default without requiring users to opt in, meaning content from private channels and direct messages can be drawn upon even though Slack claims the data is de-identified and aggregated before use. [Link to this question](#faq-what-kind-of-slack-data-is-being-used-to-train-ai-models) ### How can workspace owners opt out of Slack's AI data training? Workspace owners must send specific email requests to Slack's customer experience team to opt out. This process has been criticized as overly complex and burdensome, since it places the responsibility on users and administrators to actively request exclusion rather than giving them a simple, built-in setting to decline participation. [Link to this question](#faq-how-can-workspace-owners-opt-out-of-slack-s-ai-data) ### Why are corporate administrators and CISOs upset about this? Corporate administrators and Chief Information Security Officers argue that although big-tech vendors commonly use user data for AI development, Slack should not have made opting out the default burden on customers. They believe Slack should have used an opt-in system so users are fully aware of and agree to their data being used before any collection occurs. [Link to this question](#faq-why-are-corporate-administrators-and-cisos-upset-about-this) ### Does Slack use customer data to train its generative AI products? Slack states that its generative AI products, which rely on large language models, do not use customer data for training. The company says traditional machine learning models are handled in a privacy-protective manner with measures to prevent data leakage across workspaces, though this explanation has not eased concerns among users who feel their privacy was compromised.
