Is Gemini private? What Google saves, reviews, and connects

The Morse teamPublished October 19, 202610 min read

As of October 2026, Gemini is private from other people unless you share a chat, but it isn't private from Google. If you're 18 or over, Gemini's Keep Activity setting is on by default, so Google saves your chats to your Google Account for 18 months, uses them to train its AI models, and has human reviewers read a sample that it keeps for up to three years, even after you delete your activity. Turning Keep Activity off, or using a temporary chat, still leaves each chat on Google's servers for 72 hours.

We read Google's Gemini Apps Privacy Hub (last updated October 13, 2026), its Gemini help pages on activity, memory, temporary chats, and Personal Intelligence, the Generative AI in Google Workspace Privacy Hub, and the Google AI plans page on October 19, 2026. Google deserves credit for that hub. It gives a retention period for nearly every feature, and it says outright that reviewed chats outlive deletion.

Gemini privacy at a glance

Does Gemini save your chats?

Yes, in your Google Account, while Keep Activity is on. Google's help page says: "If you're 18 or over, Keep Activity is on by default" (Google).

Saved activity includes more than your typed prompts. The Privacy Hub lists files, photos, screens you share, audio, Gemini Live videos and screenshares, feedback, info from websites you visit with Gemini, and location info (Privacy Hub).

To see or change it:

• Find your activity: on gemini.google.com, click Settings & help, then Activity, or go straight to myactivity.google.com/product/gemini.
• Change auto-delete: on that page, click Deleting activity older than … months (or Choose an auto-delete option), then pick 3, 18, or 36 months, or Don't auto-delete activity.
• Turn it off: near the top, click On, then Turn off or Turn off and delete activity.

Off doesn't mean gone. "Even when Keep Activity is off, your conversations will be saved with your account for up to 72 hours to allow Google to provide the service and process any feedback," Google says (Google). Turning it off also switches off most connected apps; only Device assistance, Gemini Notebook, Messages, Phone, and WhatsApp keep working.

Does Gemini train on your data?

Yes, while Keep Activity is on. Google says it uses your activity "to provide, develop, and improve its services (including training generative AI models)" (Privacy Hub). Audio and Gemini Live recordings are an exception. They aren't used to improve Google's services unless you turn on a separate setting, which is off by default (Google).

Turning off Keep Activity stops future chats from being used to train Google's models, "unless you choose to send Google feedback" (Privacy Hub). Two things it doesn't stop, both in the hub's own words:

• Anonymized data. "Your Gemini settings don't control processing of your chats to create anonymized data to improve Google services."
• Protective review. "Even if your Keep Activity setting is off, Google still uses your chats to respond to you and help protect Google, our users, and the public, including with help from human reviewers."

Neither line made it into the top results we read for "is gemini private." One of them tells readers that turning activity off will "prevent your data from being shown to human reviewers," which the second line contradicts, and none mentions the anonymized-data exception.

Chats you import from ChatGPT or another AI app are covered too. Google says imported memory and chats are used "to improve our services (including training generative AI models)" (Privacy Hub).

Do humans read your Gemini chats?

Some of them. Google says "a subset of chats are reviewed by human reviewers (including Google's trained service providers)," who rate replies and write better ones that Google uses to train its models (Privacy Hub).

• What's removed first. "Chats are disconnected from your account before being sent to service providers." The link to your account is cut, but anything you wrote about yourself is still in the text.
• How long they're kept. "Reviewed chats are retained for up to three years."
• Deleting doesn't reach them. Reviewed chats, with related data like "your language, device type, location info, or feedback," are "not deleted when you delete your activity."
• Screenshots count. When Gemini uses screen automation in Android apps, its screenshots "are reviewed by trained reviewers" if Keep Activity is on.

Google's own advice to users: "Please don't enter confidential information that you wouldn't want a reviewer to see."

Feedback widens what reviewers get. If Keep Activity is off and you rate a reply, Google collects the feedback, "the last 24 hours of your chats," and any uploads or connected-app data in them, and keeps reviewed feedback for up to three years (Privacy Hub). A single thumbs-down can hand reviewers up to a day of chats.

What deleting in Gemini removes, and what it leaves

Every action below comes from Google's own pages, read October 19, 2026.

To make Gemini forget something it learned, Google says you have to do two things: delete every chat with that information, and disconnect the app it came from (Google).

Is there a private Gemini? Temporary chats

The closest thing is a temporary chat. On gemini.google.com, click Temporary chat next to New chat (Google). Google launched it on August 13, 2025, saying temporary chats "won't appear in your recent chats or Gemini Apps Activity" and won't be used "to personalize your Gemini experience or train Google's AI models" (Google).

Limits, from the same pages:

• Each temporary chat is still kept with your account for 72 hours (Privacy Hub).
• Human reviewers can still see it to "help protect Google, our users, and the public."
• It's unavailable on work and school accounts, in Gemini in Chrome, and in Gemini in Google Messages (Google).
• You can't use Gems or connected apps, or give feedback, in one.

What do connected apps and Personal Intelligence give Gemini?

A lot, if you connect them. Personal Intelligence is Google's opt-in beta that links Gemini to your Google apps, for users 18 and over on personal accounts, outside the European Economic Area, Switzerland, the UK, and Nigeria (Google). The apps it can connect include Gmail, Calendar, Drive, Google Photos, Search, Maps, YouTube, Google Wallet in the US, and Contacts with an AI Ultra subscription (Google).

What Google says it does with that data, from its page on personalization with connected apps (Google):

• It's used to "improve Google services, including training generative AI models, for everyone."
• Gemini doesn't train "directly on your Gmail inbox, Drive, Contacts, Calendar" or your Photos library, but "summaries, excerpts, generated media, and inferences" from them can feed the prompts and replies it does train on.
• Google Photos data is used "to infer your interests, relationships to people in your photos, and where you've been."
• Reviewers can see "interactions, summaries, excerpts and inferences from your relevant emails and files."

Once you opt in, Personal Intelligence is on in every new chat. You can turn it off for one chat from Tools in the text box (Google). Memory, Gemini's use of your past chats, has its own switch under Settings & help, then Personal Intelligence (Google). Google's warning for both: "Please don't connect apps to Gemini if they contain personal or confidential information that you wouldn't want to be used for training generative AI models."

Does Google use your Gemini chats for ads?

Not as of October 2026. The Privacy Hub says: "Your Gemini Apps chats are not being used to show you ads. If this changes, we will clearly communicate it to you" (Privacy Hub).

Shopping is the exception the same page spells out. Items you add to your Google shopping cart from Gemini are saved to Google Wallet, and purchases made with Google Pay in Gemini go to your Google Pay activity, each used "including for personalization and ads (depending on your settings)."

Is Gemini private on a work or school account?

It runs under different terms. Google says a work or school account "may be subject to different data handling terms," and that your Workspace administrator controls your activity settings, so "you may not be able to change your retention settings" (Google). Google's Workspace privacy hub, updated October 6, 2026, says chats and uploaded files "won't be reviewed by human reviewers or otherwise used to train generative AI models outside of your domain without your permission" (Google Workspace).

That protects your organization's data from Google's training. Your organization can still set its own retention, including keeping conversations indefinitely, according to the same Workspace hub.

Can Google hand your Gemini chats to the police?

Google says it processes Gemini data "to meet any applicable law, regulation, legal process, or enforceable governmental request" (Privacy Hub). It also keeps some data longer "when necessary for legitimate business or legal purposes, such as security, fraud and abuse prevention." With Keep Activity on and auto-delete at its default, that means up to 18 months of chats sit in your account for a valid request to reach. Our guide on whether AI chats can be subpoenaed covers how courts have treated them. This isn't legal advice.

How Morse keeps your Gemini chats private

Every question above traces back to one design choice. Gemini lives inside your Google Account, next to Gmail, Photos, Search, and Wallet, and what you tell it joins that account's record. Morse is a web app that puts over 30 models, open and closed, behind one sign-in, and it lets you use Gemini without a Google Account.

• Anonymous, to ask Gemini without Google knowing it's you. Gemini is one of the proprietary models in Anonymous mode. Our proxy strips your account, email, and IP address and sends the message under Morse's own account. Google sees the message without knowing it's you, and may keep it for a limited time to check for abuse, under its own policy. There's no Keep Activity setting to find, no 18-month history building up in your Google Account, and no Gmail or Photos connected to the chat. Morse removes who you are, not what you write, so leave out names and details that would identify you.
• Private, for a question you'd rather no host keep. It's the default for a new chat. Open-weight models like DeepSeek, Kimi, and GLM run on hosts that agreed to keep nothing. Where a host confirms zero retention on each reply, Morse checks it and refuses a reply that doesn't.
• E2EE, for anything no one should read. Pick an open-weight model, and your browser verifies the secure enclave's proof that it's genuine, then encrypts the message so only that enclave can read it. Morse's servers pass along ciphertext they can't read. It depends on the enclave hardware and attestation working as designed. E2EE chats come with Pro, at $19 a month. Here's how end-to-end encrypted AI chat works.

In all three, your chat history lives in your browser, encrypted, instead of on our servers, so there's no activity page to auto-delete and no three-year reviewed copy on our side. Morse doesn't train AI on your content, sell your data, or show ads (Morse privacy policy). Your history locks when you sign out, and unlocking it takes a key that stays on your device plus one our server issues at sign-in. Since we don't store chats, we usually have very little to give authorities. When you delete a chat or clear your browser, it's gone, and Morse can't bring it back, so keep anything you need. A Temporary chat isn't saved anywhere, your own device included.

So is Gemini private enough for you?

• Other people: yes, unless you share a chat. Check gemini.google.com/sharing, because deleting a chat leaves its link up.
• Model training: turn off Keep Activity and skip feedback. Morse doesn't train AI on your chats.
• Google's reviewers: use temporary chats for anything sensitive, knowing they're still kept 72 hours. In Morse's Anonymous mode, Google gets the message without your account attached.
• Your other Google data: don't connect Gmail, Photos, or Wallet unless you want them in Gemini's answers and its training. A Gemini chat on Morse carries only what you type or attach, with your account, email, and IP address removed.
