It depends on which account you sign in with. With a personal account, treat Copilot as a public third-party tool. With your work credentials, it runs inside your organisation's Microsoft 365 environment with enterprise data protection. Look for the green shield at the top, which shows enterprise data protection is switched on.

Is it Safe to connect ChatGPT to my Google account?
It is about as safe as the Google account itself. Connecting through an official connector does not change the security of your Google data, and both companies hold recognised security certifications. Perfect safety never exists, though, and a personal tool is never protected like a managed work environment, so for personal use the decision is yours.
Can I use AI to create Presentation slides?
Yes, AI presentation tools are fine for building a draft deck from public information. Let the tool create the structure and content from public material, then take the deck into your own tools and template and add any work-specific or confidential data there yourself. That keeps sensitive data out of public tools.
How do I stop ChatGPT from using my Data for Training?
In ChatGPT, go to Settings, then Data controls, and switch off Improve the model for everyone. The setting is backed by the provider's terms and conditions, not just a button. Many free AI tools have training switched on by default, so check the setting in every tool you use.
