Privacy is one of the biggest concerns for users when using artificial intelligence on mobile devices. Since Gemini became the default assistant on Android, many people have been wondering how secure their personal data is and how they can effectively protect it. Gemini's introduction represents a significant shift in information management, so properly configuring privacy settings in the app is essential.
Gemini integrates advanced functions and customization options, but it also entails new implications for data management. That's why we've prepared a comprehensive and detailed guide, gathering all the relevant information from official and specialized sources, so you can learn how to control all aspects of privacy in Gemini from an Android device. Whether you're a regular user or just starting out with the assistant, here you'll find tips, steps, and explanations to keep your data protected and minimize risks.
What is Gemini and how does it affect your privacy?
Gemini is the artificial intelligence assistant developed by Google, created to gradually replace the Google Assistant. This system is integrated into Android by default, which means that a large majority of users use it almost without realizing it, managing tasks, resolving queries, and interacting with other services via voice or text. Its main feature is its ability to learn and personalize responses for each individual, based on data collected during daily use.
Using Gemini involves the collection, processing and storage of personal and usage information, such as voice interactions, text, files, images, preferences, approximate location, and details of connected devices. Google has implemented policies and controls to manage this data, but privacy largely depends on how you configure the Assistant and the level of access you allow.
Data Gemini collects on Android and how it is used

Understanding what information Gemini collects is the first step in protecting your privacy. According to the official documentation, the assistant stores:
- Conversations and voice recordings, both written and audio used in Gemini Live.
- Data shared with Gemini: files, images, screenshots, browser information, and connected apps.
- Usage information, such as comments and conflicts detected during the interaction.
- Location data, which may include the approximate geographic area, IP address, and addresses associated with your Google account.
- Device information, such as identifiers, installed applications, language preferences, and on-screen content.
Google claims that this data is used to improve and personalize services, develop new products, and optimize machine learning technology. However, some of this information may be reviewed by human resources (including third parties) to improve the quality of the AI models. Before being manually reviewed, conversations are disconnected from the specific account, but it is essential not to share sensitive information in interactions with Gemini, as complete anonymity is not guaranteed.
Activity control and data storage in Gemini
Control over your activity on Gemini depends largely on the settings you choose. By default, the 'Gemini App Activity' feature is enabled for users over 18, while minors can choose to turn it on or off depending on their age and country laws.
This setting determines whether Google saves your Gemini history and activity on your account for a predetermined period (18 months by default, although this can be reduced or extended from 3 to 36 months). You can change the retention period from your privacy settings.
Important aspects about the history and human reviewers: Even if you delete your activity in the app, manually reviewed or annotated conversations may be retained for up to three years, along with related data such as language, location information, and device type. Additionally, even if you have activity disabled, recent conversations may be temporarily stored (up to 72 hours) so the system can process feedback and improve the service. This temporary activity does not appear in the app's visible history.
Essential settings to protect your privacy on Gemini
If you're looking for greater control over your privacy on Android when using Gemini, it's essential to carefully adjust several settings in the app. Below, we explain the most relevant ones based on expert advice and official sources:
1. Disable the Google Workspace extension
Gemini can access documents and files stored in your Google Drive account and other Workspace tools. While Google states that it doesn't use this content to train AI models, it's a good practice to disable this extension if you don't want AI to have access to your personal or work files.
- Open the Gemini app on your Android.
- Click on your profile picture in the top right corner.
- Go to “Extensions”.
- Find the “Google Workspace” option and disable it by moving the switch.
This will limit Gemini's access to data that may contain sensitive information.
2. Limits smart device management
Integrating Gemini with smart home devices (cameras, lights, speakers, etc.) involves additional risks. If you prefer to prevent AI from accessing or controlling these devices, it's a good idea to disable the Device Administration extension.
- Go to “Extensions” within the Gemini app.
- Find “Device Control” and disable it.
This helps reduce the potential for unauthorized access or unwanted leaks by AI.
3. Disable Gemini Activity Logging
Your interaction history with Gemini is stored by Google to analyze and improve the assistant. If you don't want the company to review your conversations, you can turn off the activity feature by following these steps:
- Open Gemini and tap your profile picture.
- Go to “Gemini Apps Activity.”
- Select the “Disable” option from the corresponding menu.
This will prevent Google from continuously associating your conversations with your account, although keep in mind that some interactions will still be temporarily saved for basic service functionality.
4. Block the use of additional personal data
Gemini may use personal information stored in other Google apps, such as Gmail, Maps, or Calendar, in order to offer more personalized responses. If you prefer to maintain this fragmentation and avoid global access to your data, disable personalized results:
- Open the Gemini app and go to “Settings.”
- Select “Google Assistant Features on Gemini.”
- Turn off “Use Google Assistant features.”
This will prevent the AI from collecting information from other apps to enhance its responses, thus limiting the level of personalization at the cost of increased privacy.
5. Be careful with confidential information
Beyond the technical options, the human factor remains key. Experts recommend avoiding sharing banking details, password information, sensitive topics, or personal locations through Gemini, even if you trust Google's privacy measures. The company warns that some content may be supervised by human reviewers and even stored for up to three years if it was part of a review to improve AI quality.
- Never share banking information or passwords.
- Avoid raising sensitive issues or delicate political/religious discussions.
- Do not upload high-risk personal files.
Caution when interacting with AI can make all the difference.
Gemini on Android and device permissions
For proper functioning, Gemini requests various access permissions to device functions, such as the microphone, camera, contacts, phone dialer, location, or access to visible on-screen content. It's important to manage these permissions and grant only those necessary for the features you'll actually use.
- You can manage permissions from your Android's general privacy settings, or access specific permissions in Settings > Apps > Gemini > Permissions.
- Revoke permissions that are not essential for your use.
Limiting permissions helps reduce the exposure of private information to potential incidents.
Gemini's specific operation as an assistant on Android
Gemini's behavior may vary depending on whether it's used independently or as a replacement for the older Google Assistant. Some key aspects include:
- Integration with “Hey Google” and Voice Match: If these features are enabled, you can wake Gemini with your voice, but it may be triggered by mistake or similar sounds. What you say will be treated as a standard request and, if you have the activity enabled, will be used to improve the AI.
- Importing Google Assistant History: In some territories, recent actions performed with the old assistant may migrate to the new Gemini history.
- Permission differentiation: Gemini may require additional permissions if you perform tasks through Google Assistant, with specific settings for each feature.
It's a good idea to periodically review your settings and understand the differences to maintain control over what data is shared and stored.
Privacy and Security in the Gemini API and Custom Development
For developers and businesses, the Gemini API offers several parameters to adjust security settings, allowing filters to be adapted according to the context of use. These filters include harassment prevention, sexual content, dangerous material, or queries on civic issues.
The API allows you to set specific thresholds based on the likelihood that content is unsafe: from blocking nothing, to blocking even with a low probability of risk.
| Configuration | Description |
|---|---|
| Do not block | Always show content, without blocking. |
| Block little | Block only content that is highly likely to be unsafe. |
| Block something | Block with medium or high risk probability. |
| Block most | Blocks even content with a low probability of risk. |
Standard users can't completely disable filters, but they can limit the data they share to improve privacy. Developers can adjust the settings to their needs, while respecting Google's limits.
Privacy in Gemini for Developers: Android Studio and Google Cloud
Gemini integrates into professional environments such as Android Studio and Google Cloud, where there are additional guarantees and specific controls for the corporate sphere.
Gemini in Android Studio
