You open Gmail to check your email. In the background, an artificial intelligence system is reading those emails, summarising them, suggesting replies, and processing the contents — whether you asked it to or not.
This is not a conspiracy theory. It is a description of how Gemini AI, integrated into Gmail since January 2025, works by default for most users.
In October 2025, Google was sued for allegedly enabling Gemini by default across Gmail, Google Chat, and Meet without the consent of users or notifying them — despite marketing Gemini as an opt-in feature. The lawsuit argued that Google buried the opt-out controls deep within its privacy settings, effectively giving the company system access to the entire recorded history of users' communications.

Proton, the privacy-focused technology company, describes the situation directly: Big Tech like Google, Microsoft, and OpenAI tend to treat your data as a business asset — and AI tools are an especially effective way to collect data about your personal life, your work life, your health, and your financial records — the kind of information that can be analysed, packaged, and monetised.

This article explains exactly what Gemini can access in your Gmail, why many users and privacy experts are concerned, and the precise steps you can take right now to limit or disable it.
What Gemini in Gmail Actually Does With Your Data
Gemini is Google's artificial intelligence model, integrated into Gmail, Google Drive, Google Docs, Google Photos, and other services as of January 2025. In Gmail specifically, Gemini powers several features that are turned on by default for most users:
Smart Compose — Gemini suggests sentences and completions as you type emails, based on the content of the email and your past writing patterns.
Smart Reply — Gemini generates short reply suggestions based on the content of incoming emails it has read.
Email Summaries — Gemini reads and condenses email threads to show you a brief summary at the top of the conversation.
Inbox Suggestions — Gemini analyses your inbox and suggests priorities, to-do items, and follow-up actions based on the content of your messages.
To provide these features, Gemini must read the content of your emails. According to Google's own Gemini Apps Privacy Hub, when you use connected apps in Gemini, Google processes your data to provide, maintain, and improve services, develop new products and features, understand how people use services, and customise the experience using your past conversations and location information.

Google states on its privacy page that even with activity tracking switched off, chats and processed content are stored for up to 72 hours to provide the service. Conversations sampled for human review are kept for up to three years, disconnected from your account — and deleting your activity does not remove them.

Tuta, the encrypted email provider, reported in May 2026 that Google Chrome quietly installed a 4 GB Gemini Nano AI model on users' devices without notification — meaning the AI processing was occurring locally on users' computers without most of them being aware.

Why This Is a Privacy Concern Worth Taking Seriously
Whether Gemini's data access in Gmail is something you are comfortable with is ultimately a personal decision. But the concern is not trivial — and it is not being raised only by privacy advocates.
Your Emails Contain Your Most Sensitive Information
Think about what passes through your Gmail inbox on any given week: bank statements, salary notifications, medical appointment confirmations, conversations with lawyers or accountants, private family matters, and business communications. An AI system reading this content — even one operated by a company with legitimate intentions — represents a level of access to your private life that most people have never explicitly consented to.
Google Has a Documented History of Privacy Issues
Proton notes that in 2024 alone, Google's parent company Alphabet was fined nearly 2.9 billion dollars for violations including monopolistic practices, failing to comply with regulators, and illegally favouring its own digital advertising services. The company has faced multiple privacy-washing campaigns — promising users control over their data while making opt-out settings difficult to find.

Data Shared With Third-Party Services
According to Proton's analysis, if you use Gemini either within or outside Gmail, your data can be shared with third-party services. Add-ons and extensions can connect Gemini to other services, allowing those companies to process your data under their own, separate privacy policies. Once your data leaves Gmail's immediate environment, what happens to it becomes significantly harder to track.

Smart Features Are Turned On Without Asking
Tuta confirmed that Google turned on smart features, including Gemini-powered inbox processing, without user consent — and that these settings override previous privacy preferences users had set. A Google email notification to Android users announced that Gemini would gain access to Messages, WhatsApp, and Utilities, regardless of whether Gemini Apps Activity was previously switched off.

[H3] The Opt-Out Is Deliberately Difficult to Find
MajorGeeks, a long-running technology publication, confirmed that Gemini's opt-out controls are not prominently displayed — and that some useful features such as Gmail calendar event detection are bundled with Gemini under the same settings, making it impossible to selectively disable AI access while retaining other smart features. Users face an all-or-nothing choice.
What the Lawsuits and Official Complaints Say
The privacy concerns around Gemini in Gmail are not only being expressed by individual users and privacy companies.
In October 2025, a lawsuit was filed alleging that Google violated the California Consumer Privacy Act by enabling Gemini by default across Gmail, Google Chat, and Meet without user consent and without notification. The lawsuit specifically argued that opt-out controls were buried deep within privacy settings, effectively preventing most users from exercising meaningful control over how their communications were processed by AI systems.
Google denied the allegations and stated that Gmail content is not used for training its Gemini AI model. However, as Proton's analysis noted, Google's own privacy policy phrasing confirmed that if you ask Gemini to access personal data — including emails — that information may be used to improve its models. Google also acknowledged that even with activity tracking switched off, conversations may still be processed to create anonymised data.
NordVPN noted that Gemini's integration into Workspace raised questions about intrusiveness and prompted significant search activity from users seeking to disable the feature. NordVPN confirmed that at the time of writing, fully turning off Gemini in Gmail and other services is not always straightforward — with some Workspace users required to contact Google Support directly to access the relevant settings.

Whether the lawsuit succeeds or not, the underlying situation is clear: AI has been integrated into one of the world's most widely used email services with default-on settings that most users were never explicitly informed about.
How to Turn Off Gemini in Gmail — Step by Step
There are three levels of control available to you, as identified by tech researcher Tobias Holm in his comprehensive guide to disabling Gemini:
Level 1 — Hide it: Disable the visible Gemini features in Gmail settings
Level 2 — Remove it: Delete the Gemini app from your device
Level 3 — Stop the data: Turn off Gemini Apps Activity to limit data storage and AI training:
https://www.tobiasholm.com/tech/how-to-turn-off-gemini
For most users, completing Level 1 and Level 3 together provides the best practical protection.
Turn Off Gemini Smart Features in Gmail on Desktop
Step 1: Open Gmail in your browser and click the Settings cog icon in the top right corner.
Step 2: Click "See all settings."
Step 3: In the General tab, scroll down and find "Smart features and personalisation."
Step 4: Uncheck the box next to "Turn on smart features in Gmail, Chat, and Meet." Confirm by clicking "Turn off and reload."
Step 5: Return to the same settings tab and find "Manage Workspace smart feature settings." Switch off both "Smart features in Google Workspace" and "Smart features in other Google products."
Important: You must turn off smart features in both locations — disabling only one is not sufficient. MajorGeeks and Tuta both confirm this is a common mistake that leaves Gemini partially active.
Turn Off Gemini Smart Features in the Gmail App on Mobile
Step 1: Open the Gmail app on your phone.
Step 2: Tap the three lines in the top left corner and go to Settings.
Step 3: Tap your account name.
Step 4: Scroll down to find "Smart features and personalisation" and turn it off.
Step 5: Do the same for "Smart features in other Google products."
Note: These settings do not sync across multiple accounts. If you use more than one Gmail address, you must repeat the process for each account separately.

[H3] Disable Gemini on Android Device Level
Step 1: Go to your phone's Settings.
Step 2: Tap Apps, then find Gemini in your app list.
Step 3: Tap Default apps and change the digital assistant from Gemini to Google Assistant.
Step 4: Alternatively, open the Gemini app, tap your profile icon, and select Uninstall or disable the app.
Tuta cautions that even after uninstalling the Gemini app, Gemini features within Gmail, Chrome, and Google Search continue to function — because those operate at the account level rather than the device level, and require the settings above to be turned off separately.
Disable Gemini in Google Drive
Step 1: Open Google Drive in a browser on desktop.
Step 2: Click the Settings cog in the top right corner.
Step 3: Go to Manage apps.
Step 4: Find Gemini in the list and uncheck "Use by default."
For mobile: open Google Drive in your phone's browser, tap the three lines in the top left, select Desktop Version, then follow the same steps as above. This setting is not accessible through the mobile app directly.
How to Stop Gemini Activity Tracking — The Most Important Step
Turning off smart features controls what you see from Gemini. But according to Tobias Holm's research, these feature-level settings do not stop what Google stores, reviews, and potentially trains on in the background. For that, you need to turn off Gemini Apps Activity separately.
Turn Off Gemini Apps Activity
Step 1: Go to myactivity.google.com/product/gemini in your browser — or open the Gemini app and tap your profile icon.
Step 2: Find the setting called "Gemini Apps Activity" — this may also be labelled "Keep Activity" as Google is currently renaming this setting.
Step 3: Tap Turn off, then select "Turn off and delete activity" to clear stored history as well as stopping future activity from being saved.
What this does: switching Gemini Apps Activity off stops your interactions from being stored long-term, reduces the chance of conversations being sampled for human review, and limits use of your data for AI model improvement.
Important caveat from Google's own documentation: even with this setting off, processed content is still stored for up to 72 hours to provide the service. Conversations previously sampled for human review are retained for up to three years and are not deleted even if you clear your activity history. Google's advice is direct — do not enter anything into Gemini that you would not want a reviewer to see.
What Happens After You Turn It Off
After disabling Gemini smart features in Gmail, the following changes will take effect:
Smart Compose suggestions will no longer appear as you type emails.
Smart Reply options will no longer appear on incoming emails.
Inbox summaries generated by AI will no longer be displayed.
Gemini's AI-powered to-do list and priority suggestions will stop appearing.
MajorGeeks notes that some other useful non-AI features — such as Gmail events automatically appearing in Google Calendar — are bundled with the same settings and will also be disabled when Gemini smart features are turned off. This is an acknowledged limitation of Google's current settings structure.
NordVPN notes that Nym's analysis confirms turning off AI features does stop background processing, freeing device CPU and network resources — meaning performance improvements are a secondary benefit alongside the privacy benefit.

Frequently Asked Questions
Does turning off smart features in Gmail mean Gemini stops accessing my emails completely?
Turning off smart features stops Gemini from actively processing your emails to display suggestions, summaries, and replies. However, Google's own privacy documentation confirms that some processing continues for up to 72 hours after any interaction, and that previously reviewed conversations may be retained for up to three years. Turning off Gemini Apps Activity in addition to smart features provides the strongest available protection within the current settings framework.
Can I turn off Gemini completely if I use a Google Workspace account?
For individual Google accounts, the settings described in this article provide meaningful control. For Google Workspace accounts managed by an organisation, turning off Gemini completely requires the account administrator to disable it through the Admin Console at admin.google.com — individual users cannot do this themselves on a managed account. NordVPN confirmed that some Workspace users have been required to contact Google Support directly to access the relevant administrative controls.
https://nordvpn.com/blog/how-to-turn-off-gemini/
Is Google using my Gmail emails to train its AI models?
Google denies that Gmail content is used for AI training without consent. However, Google's own privacy policy confirms that if you ask Gemini to access email content, that information may be used to improve its models. Turning off Gemini Apps Activity reduces — but according to Google's own documentation, does not fully eliminate — all processing of your data in the background.
https://support.google.com/gemini/answer/13594961?hl=en
Will my Gmail still work normally after I turn off Gemini?
Yes. Gmail's core functions — sending, receiving, organising, and searching emails — are entirely unaffected by disabling Gemini smart features. Only the AI-powered features described in this article will stop. The experience will be similar to how Gmail worked before Gemini was introduced in 2025.
I turned off smart features but Gemini suggestions are still appearing. What should I do?
This is the most common outcome when only one of the two required settings has been disabled. Make sure you have turned off smart features in both locations — the main smart features toggle and the Workspace smart features toggle — in both Gmail's web settings and the mobile app separately. If suggestions still appear after completing all steps, clearing your browser cache and signing out and back into your Google account may resolve the issue.
Does this apply to other Google apps like Drive, Docs, and Photos?
Yes. Gemini has been integrated into Google Drive, Docs, Sheets, Slides, and Google Photos as well as Gmail. Each requires separate settings to be adjusted. MajorGeeks provides a guide covering Drive and Chrome specifically. Tuta provides a comprehensive guide covering Gmail, Chrome, Photos, and Android.
Is there a completely private alternative to Gmail?
Several encrypted email providers offer services in which even the email provider itself cannot read your messages. Proton Mail uses end-to-end encryption for messages between users on the same platform, and password protection for emails sent to external addresses. Tuta similarly offers end-to-end encrypted email as a privacy-focused alternative. Whether switching providers is the right choice depends on your individual privacy requirements and how heavily you rely on Google's wider ecosystem.

The Bottom Line
Gemini in Gmail is not a feature most users chose — it was enabled by default, and its opt-out controls are not prominently displayed. As Proton, Tuta, NordVPN, and cybersecurity researchers have all confirmed, the AI has access to some of the most sensitive personal information most people own: their emails.
Whether you decide to leave Gemini active, disable some features, or take full steps to limit its data access is a personal decision. But it should be an informed one — made with a clear understanding of what is being accessed, how long it is stored, and who can review it.
The steps in this article take under five minutes and put you back in control of one of the most private spaces in your digital life.
Share this article with anyone who uses Gmail and has never checked these settings. Most people have no idea this is happening — and the option to change it is buried precisely where most users will never think to look.
