How to Stop Gemini Using Your Data for Training

Short Answer

To limit how Gemini uses your conversations for model improvement, open the Gemini activity controls and turn off Keep Activity or Gemini Apps Activity, depending on the label shown in your account. For a one off conversation, Google's Temporary Chat feature is another option. Google says Temporary Chats do not appear in recent chats or Gemini Apps Activity, are not used to personalize Gemini or train its AI models, and may be kept for up to 72 hours to provide the service and process feedback.

These settings are useful, but they are not a promise that no data is ever processed or retained. Google describes separate purposes such as service delivery and safety, and the controls can change as the product changes. Read Google's official Gemini privacy update and the Gemini privacy and safety page before relying on a setting for sensitive work.

What the Question Really Means

People often use “training” to describe several different things: saving chat history, using conversations to improve AI models, personalizing answers from past chats, or letting Gemini work with connected apps. Those are related but not identical. Turning off one setting may change how activity is saved without changing every other feature on your phone or in your Google account.

Your goal matters. If you want Gemini to stop keeping a long history of your chats, review the activity setting and the deletion controls. If you want a one time conversation that does not affect personalization, consider Temporary Chat. If your concern is a company document, first check your organization's policy and the terms for the exact Gemini product you use.

The safest approach is to use the narrowest control that matches your need, then confirm what it changes. Do not assume that a switch labelled “activity” controls all Google services, your Android permissions, or every connected application.

How It Works

Google's August 2025 announcement introduced Temporary Chats and updated controls for data used to improve Gemini. The company said the activity setting would be renamed Keep Activity. When the setting is on, a sample of future uploads may be used to improve Google services. Google also described a separate control for whether audio, video, and screen shares provided through Gemini Live are used to improve services.

Google's privacy information explains the controls available in the Gemini mobile app and web experience. Depending on the account and rollout, the exact label and path may differ. Some settings also apply to particular product experiences rather than every Google service. Check the current on screen description before making a change.

Temporary Chat is a distinct option. Google's announcement says those conversations do not appear in recent chats or Gemini Apps Activity and are not used to personalize the Gemini experience or train Google's AI models. The company says they may be kept for up to 72 hours to provide responses and process feedback. That retention window is a useful reminder that “not used for training” does not mean “never processed.”

Practical Steps

1. Open the Gemini settings

Open Gemini in your browser or mobile app and make sure you are using the account you want to control. Open the settings menu and look for Keep Activity or Gemini Apps Activity. Google has changed the label over time, so follow the wording displayed in your account rather than a screenshot from an old tutorial.

If you use a work or school account, your administrator may manage some settings. In that case, check the workspace policy or ask the administrator which controls apply. Do not assume that the consumer settings are identical to the settings for an organization account.

2. Turn off the activity setting

Read the description next to the activity control. Choose the option to turn it off if you want to limit the saving and use of future activity described by Google. If the interface offers “turn off” and “turn off and delete activity,” treat them as separate choices. The second option may remove past activity, so read the confirmation before selecting it.

After changing the setting, confirm that the interface shows it is off. If the app asks you to confirm the change, complete that step. Do not assume the control changed simply because you opened the menu or tapped the label.

3. Use Temporary Chat for one off questions

When available, start a Temporary Chat for a conversation you do not want included in normal chat history or used for personalization. Confirm that the interface clearly indicates Temporary Chat before sharing anything. Google's stated handling for Temporary Chats is different from normal saved activity, but the conversation is still processed to provide a response.

Temporary Chat is useful for general questions that do not need a long term history. It is not a secure vault for passwords, financial records, medical details, confidential source code, or private client data. Avoid sharing sensitive information unless you have checked the terms and have a clear reason to do so.

4. Review existing activity separately

Turning activity off is not the same as deleting old conversations. Open the activity controls and review the options for managing past activity. If you choose to delete it, check the date range and account carefully before confirming. Keep in mind that deletion in one product may not delete copies you saved elsewhere or data that Google says it must retain for other purposes.

If you need records for work, export or preserve any material your organization requires before deleting it. If your goal is privacy rather than record cleanup, read the explanation of each option and make only the change you intend.

5. Check related controls

If you use Gemini Live, review the separate setting for audio, video, or screen shares used to improve Google services. Google described this control separately from the general activity setting. Do not assume one toggle covers every media type.

If Gemini is connected to other apps or services, review those connections and the permissions for the relevant account. An activity control is not a replacement for app permissions, device settings, or company access rules. Use the current Gemini Privacy Hub to confirm what each connection can access.

Common Problems

The setting may have a different name in an older guide. Google announced that Gemini Apps Activity would be renamed Keep Activity, so search for both terms in the official help pages and your current interface. If you cannot find the control, confirm that you are in Gemini settings rather than general Google Account settings.

Another issue is expecting the history to remain unchanged after turning activity off. Some settings affect whether future activity is saved, and deleting past activity is a separate action. Read the choices carefully before confirming. If you need a record of earlier conversations, do not choose a deletion option without checking what it removes.

Users may also think that a paid account automatically excludes data from improvement. Do not rely on that assumption. Privacy terms depend on the product, account type, and settings. Read the policy for the exact account you use, especially when a company or school manages it.

Finally, an activity setting does not make every prompt safe. A conversation may still be processed to provide the service or protect it from abuse. Keep sensitive data out of prompts unless you have confirmed that sharing it is allowed.

What Does Not Work

Deleting a conversation from the visible chat list is not a substitute for reviewing the activity controls. Likewise, turning off activity is not the same as reviewing all connected apps and media settings. Each control has its own purpose.

Do not assume Temporary Chat means zero retention. Google's own description says temporary conversations may be kept for up to 72 hours for service delivery and feedback handling. That is different from using them to train a model, but it is still data processing.

Do not copy instructions from a forum without checking the current official interface. User reports can be useful for finding confusing wording, but they may describe another version or account type. Use official Google documentation for the final decision.

Safety and Limitations

For personal use, avoid sharing passwords, identity documents, bank details, private messages, or confidential work files with an AI assistant. For business use, follow your employer's approved tools and data classification rules. If a document contains client or employee information, remove details that are not needed for the task.

Privacy settings reduce certain uses of data, but they do not replace legal, security, and workplace obligations. Check the terms for your account, especially if you use a managed workspace. If the product is part of a regulated workflow, ask the appropriate privacy or security team before uploading protected data.

Google can update controls and retention terms. Revisit the official Gemini Privacy and Safety page and the Temporary Chats announcement when the interface changes. A clear record of the setting you changed is useful, but do not assume it applies to other Google products.
