Data that stays out of public AI tools

• CRM and ERP exports with client and employee names: anonymize them before uploading to a public service
• Company financials before publication: into a service only inside a corporate environment or with placeholder names
• API keys to systems and databases: keep them in secrets, never in cells or prompts
• Model analysis results: check them on a control sample before they go into a report
• Personal data in raw data: remove columns with names, phones and addresses before analysis
