Is Claude safe to use?

Last reviewed: 21 July 2026
Does Claude train on what you type?
Yes, by default.
Can you turn Claude's training off?
Settings → Privacy → keep Model Improvement off (or turn it off if enabled). Use Incognito chats for sensitive work; Incognito chats are not used for model improvement even if Model Improvement is enabled. Avoid thumbs-up/down feedback on sensitive conversations.
What happens to your data when you use Claude?
Anthropic collects prompts and responses for Claude. Current consumer privacy docs say Claude Free, Pro, Max, and Claude Code chats/coding sessions are used to improve models only if you enable Model Improvement, if a conversation is flagged for safety review, or if you otherwise explicitly opt in. Feedback can be stored and used for improvement; commercial Claude for Work and API usage have separate protections.
The Gentleman's take
“Anthropic made its name on safety, so the 2025 shift to training on consumer chats by default raised eyebrows, mine included. To its credit, the opt-out is plainly placed and the policy readable. Turn the setting off, and you are back on comfortable ground.”
