Is Gemini safe to use?

October 1, 2026

Yes, the official Gemini app from Google is safe in the ordinary sense. The risks are about what you type into it. Per Google, chats are saved for 18 months by default and used to improve its models. A subset is read by human reviewers, and those reviewed chats can be kept for up to three years, even after you delete your activity. Like any chatbot, it can also be confidently wrong. Use it, but keep confidential details out, check important answers, and look at your activity settings. (If you meant Gemini the crypto exchange, that is a different company.)

First: which Gemini?

Many searches for "is Gemini safe" are about Gemini, the cryptocurrency exchange, which has nothing to do with Google. This page is about Google's Gemini AI assistant: the app, gemini.google.com, and Gemini inside Google's other products.

Is the Gemini app itself safe?

The official app, published by Google in the App Store and Google Play, is safe to install and use. As with any popular AI tool, lookalike apps and "Gemini Pro unlocked" offers exist to collect logins or payments. Check that the developer is Google, and use the web version at gemini.google.com if in doubt.

What Google keeps

This is the part that matters most. Per Google's Gemini Apps Privacy Hub:

  • With Keep Activity on, which is the default, chats are saved for 18 months unless you choose 3 months, 36 months or never.
  • Saved activity is used to improve Google's models.
  • Even with Keep Activity off, or in a temporary chat, Google keeps each chat for 72 hours.

The full breakdown is in is Gemini private.

Human reviewers

Google says a subset of conversations is read by human reviewers to improve its products. Reviewed chats are disconnected from your account and can be kept for up to three years, and deleting your activity does not remove them. That is why Google itself advises against entering anything confidential, or anything you would not want a reviewer to see.

It can be wrong

Like every chatbot, Gemini can give confident answers that are wrong. For anything medical, legal, financial or safety-related, treat it as a starting point and check a real source. The same advice, for ChatGPT, is in is ChatGPT safe to use.

Work and school accounts

On a Google Workspace account, your organisation's admin settings decide retention and access, not your personal settings. Keep personal questions on a personal account.

How to use Gemini more safely

  • Review Keep Activity: shorten the auto-delete period or turn it off if you do not need the history.
  • Use a temporary chat for sensitive questions, remembering the 72-hour window.
  • Keep confidential details out: passwords, card numbers, ID numbers and other people's private information.
  • Be careful with feedback. Per Google, sending feedback can include recent conversation history with your report.
  • Install only the official app.

The wider picture, across assistants, is in AI privacy concerns.

Where nixm fits

nixm doesn't keep a transcript. A distilled log of the session stays with the signal for seven days, then dissolves, along with any images you uploaded. There are no reviewers reading samples and no training on conversations.
