AI Tools Privacy & Safety Guide: What Never to Share
Updated 2026-10-25 · 8 min read · AI Tools World editorial team
AI tools are powerful because you give them context: documents, emails, photos and ideas. That same context is valuable to scammers and could be stored longer than you expect. These rules help you get the benefits without unnecessary risk.
Never paste these into an AI tool
- Passwords, one-time codes, recovery phrases and API keys.
- Bank card numbers, account numbers and identity document numbers.
- Other people's private information without their permission.
- Confidential company data unless your employer has approved the tool.
- Medical or legal documents in tools that do not offer appropriate protection.
Privacy settings to check on day one
- Whether your chats or files are used to train models, and how to opt out.
- Chat history settings and temporary or incognito modes.
- How to delete individual conversations and your whole account.
- Which connected apps (email, drive, calendar) have access, and why.
Common AI-related scams
- Fake apps and browser extensions using the names of popular AI tools. Install only from official websites and stores.
- “Lifetime access” deals for well-known paid products from unknown sellers.
- Voice-clone calls pretending to be a family member who urgently needs money. Agree a family code word.
- Investment schemes claiming an AI trading bot guarantees profits.
Protect your AI accounts
- Turn on two-factor authentication wherever it is offered.
- Use a unique password stored in a password manager.
- Review active sessions and log out of shared devices.
- Watch for unexpected usage or billing — it can signal a leaked API key.
For businesses and developers
Keep API keys on a server, never inside website or app code that users download. Set spending limits in each provider's billing dashboard, rotate keys regularly and give each project its own key so one leak does not expose everything.
Check what the AI tells you
AI models can produce convincing but incorrect answers. For health, legal, financial or safety decisions, use AI to prepare questions — then confirm with a qualified professional or an official source.
Frequently asked questions
Can AI companies read my chats?
Policies differ. Many providers may review some conversations for safety or quality. Read the privacy policy of each tool and use business plans for sensitive work.
What should I do if I leaked an API key?
Revoke it immediately in the provider's dashboard, create a new key, check your usage and billing for unexpected activity and set a spending limit.
