Data that stays out of public AI tools

• The executive's correspondence with partners and investors: into a public service only as anonymized fragments
• Personal data of the executive and family: passports, tickets, addresses, medical records, never into third-party services
• Meeting recordings and decisions before they are announced: anonymize the transcript and restrict access to the notebook
• Access to the executive's email, calendar and bank cards: passwords are never pasted anywhere
• Contract registers with real amounts: keep them in the corporate workspace
