When you use AI tools, the data you enter may be stored, reviewed or used to train models — so treat AI chats as not fully private. A few settings and habits protect you.

What happens to your data?

Many consumer AI tools may store your conversations and, depending on the tool and settings, use them to improve their models. Some let you opt out of training or delete history; enterprise tiers often promise no training on your data. Free tiers tend to have weaker protections. Always check the specific tool’s privacy policy.

How to protect yourself

Don’t enter sensitive personal, financial, health or confidential company information into consumer AI. Use privacy settings and opt out of model training where offered. Delete chat history you don’t need. For sensitive work, prefer tools with strong privacy terms, enterprise data protections, or local/self-hosted models that keep data on your device.

The jurisdiction angle

Where your data is stored is not the same as which laws can reach it. Where data is stored is not the same as which laws reach it: under the US CLOUD Act, data held by a US-jurisdiction provider can be subject to US legal process even if it physically sits in the EU. That gap is why data-sensitive teams look at self-hosting or providers outside US jurisdiction — not just at picking a region. For most personal use this is academic, but for sensitive business data it is a real consideration — which is why some organisations choose self-hosting or providers outside US jurisdiction.

Businesses weighing data control often look at self-hostable platforms: osFoundry, for example, can run models locally or deploy into your own cloud account, so sensitive data need not leave infrastructure you control.
