A modern smartphone stores more personal information than any physical diary or wallet ever created by humanity. Geolocation, correspondence, photos and even biometric data - all this becomes available to dozens of applications immediately after installation. Users often do not even suspect that a flashlight or calculator can request access to contacts, and do not understand where exactly in the system this can be limited.
The operating system Android provides powerful tools for controlling privacy, but Google developers are constantly changing the location of the settings in new versions of the shell. If in older versions everything was relatively clear, then in current builds the menu privacy is scattered across different sections or hidden behind smart functions. Finding these options can be time-consuming if you don't know the exact navigation paths.
In this article, we'll take a closer look at where the key levers are to control the security of your data. We'll look at both standard settings menus and specialized tools like Rights Manager and Secure Folder, which allow you to isolate sensitive information from prying eyes.
Privacy Control Center and Quick Access Toolbar
Starting with Android 12, Google has introduced a centralized hub where all the main privacy switches are collected. You can find it through the standard settings menu by selecting Privacy. This is the first and most important step that every device owner needs to take immediately after purchasing or updating the system.
Inside this section you will see a summary of activity: which applications accessed the camera, microphone or geolocation in the last 24 hours. The system groups data into categories, allowing you to quickly identify “troublemakers.” For example, you may be surprised to see that a food ordering app regularly scans your location, even when it is closed.
⚠️ Warning: The menu interface may vary significantly on smartphones from different manufacturers (Samsung, Xiaomi, Pixel). If you don't find the "Privacy" item in the main menu, try using the settings search or look at the "Security and Privacy" section.
Particular attention should be paid to the activity indicators in the top right of the screen. The green dot indicates the camera is working, the orange dot indicates the microphone. Clicking on these indicators will instantly take you to the app that is currently using the sensors. This allows you to control in real time who is “listening” or “watching” through your gadget.
Enable the “Confidential data access indicators” function in the settings if they are disabled by default - this is your visual shield against hidden spying.
Application rights manager and granular access control
The most effective method of protection is the principle of least privilege. Each application should receive exactly as many rights as necessary for its operation, and not a byte more. To manage this, use Rights Managerlocated along the path Settings → Applications → Rights Manager.
Here permissions are divided into logical groups. You can see a list of all apps that have access to:
- 📍 Geolocation (exact location or only approximate)
- 📷 Camera and microphone
- 📞 Contacts and SMS messages
- 📁 Files and multimedia
- 📅 Calendar and reminders
It is important to regularly check the “Allowed all the time” section for geolocation. Many services, such as maps or taxis, really need constant access, but for messengers or games this is unnecessary. Change the setting to "Only while in use" to limit background data collection.
Modern versions of Android now have the One-Time Permissions feature. When you first launch the app, it will ask you to access your microphone and you can select the “This time only” option. After closing the app, access will be automatically revoked, and the next time you start the request will be repeated.
Advertising identifiers and tracking trackers
Even if you have limited access to the camera, your smartphone continues to collect data about your habits for advertisers. advertising identifier (Advertising ID) is responsible for this. This is a unique code that is assigned to your device and allows companies to build a profile of your interests.
To limit targeted advertising, you need to go to the Google → Advertising section in settings. Here you can reset the current ID, which will reset the accumulated profile, or delete it completely. After deletion, advertisers will no longer receive your unique code, although advertising will not go anywhere - it will simply become less relevant.
It is also worth paying attention to the settings inside the store itself Google Play. In Settings → General → Account Settings, you can disable ad personalization based on YouTube search history and views. This reduces the level of digital noise, although it does not guarantee complete anonymity.
| Identifier type | Where to find | What does disabling provide |
|---|---|---|
| Google Advertising ID | Settings → Google → Advertising | Reset adware profile |
| AAID (Amazon) | Amazon application settings | Amazon tracking restriction |
| IDFA (iOS analogue) | Not applicable to Android | - |
Why does advertising remain even if I turned everything off?
Disabling identifiers does not block advertising completely. It only breaks the connection between your online behavior and the ads you see. You will see random ads, but the algorithms will no longer use your personal data to select them.
Secure folder and data isolation
To store particularly sensitive files (photos, documents, banking applications) in Android there is a concept of isolated space. On Samsung devices, this function is called Secure Folder (Secure Folder); on other brands, analogues like “Second Space” or “Personal Safe” may be used.
This function creates an encrypted container within the system, access to which is protected by a separate PIN code, pattern key or biometrics. Even if someone unlocks your phone, they will not be able to open the contents of this folder without additional authorization.
Applications installed inside the Secure Folder are completely isolated from the main system. They have their own data, their own accounts and their own caches. You can have two copies of WhatsApp or Telegram: one regular and one hidden in a secure perimeter.
⚠️ Attention: If you delete the Safe Folder or reset your phone without first backing up, all data inside the isolated container will be irretrievably lost. Standard cloud backups may not cover them.
To activate this feature, you usually need a manufacturer account (for example, Samsung Account). After turning on, a separate icon will appear in the application menu through which you enter the protected area.
☑️ Setting up a data isolate
Geolocation: accuracy and history of movements
Geolocation is one of the most sensitive parameters. In addition to managing app permissions, it's worth checking your global location service settings. Go to Settings → Location (or Geoservices).
Here it is important to pay attention to the “Location History” (formerly known as Google Timeline). This function saves the route of your movements with high accuracy. If you do not If you use it for navigation or smart reminders (“remind me to buy bread when I’m near the store”), it is better to disable it or configure automatic deletion of data every 3 months.
It is also possible to use “Approximate location” instead of an exact one. For most applications (news, weather, food delivery), knowing your city or area is enough; they do not need house coordinates accurate to the meter.
B. Android 14 and newer introduced a feature for temporary access to geolocation. You can allow an application to access maps only for 10 minutes or for one session, after which access will be automatically closed by the system.
Using approximate geolocation instead of exact one is the best balance between application functionality and your anonymity in everyday use.
Safe browsing and protection from phishing
Protecting privacy is not only about hiding data, but also preventing data theft. Built-in protection Google Play Protect and the Safe Browsing feature in Chrome help you avoid malicious sites and dangerous downloads.
This setting is located along the way Settings → Google → Security. Here you can check the device's protection status, see a list of applications that have access to important functions, and run a virus scan. It is recommended to run such a check regularly at least once a month.
Particular attention should be paid to notifications about potentially dangerous applications. If the system warns that an externally downloaded application may be malicious, you cannot ignore this message. Often such apps contain keyloggers that read password input.
In addition, you should enable “Enhanced Protection” in the Chrome browser settings. This sends samples of suspicious files and URLs for analysis to Google in real time, allowing you to block phishing attacks before you enter your data on a fake site.
Do you need to install an antivirus on Android if you have Google Play Protect?
For most users, Google's built-in protection is enough, especially if you only download apps from the official Play Market store. Third-party antiviruses often require excessive rights, slow down the system, and display intrusive ads. Installing an antivirus only makes sense when installing applications from unknown sources (APK files) or on devices with an outdated version of Android that no longer receives security patches.
Can the owner of a Wi-Fi network see what applications I use?
The owner of a Wi-Fi router sees which IP addresses your device visits and how much traffic is consumed. However, thanks to the HTTPS encryption protocol, which is used by most modern applications and sites, the (contents of) transmitted data, passwords and messages remain hidden. They see the fact of the connection, but not its content.
What if an application requires access to contacts in order to work?
If an application (for example, a simple photo editor) requires access to contacts for no obvious reason, this is a “red flag”. Try granting access and then immediately disabling it in the permissions settings. If the application stops working or produces errors, it is better to find an alternative. Many modern operating systems allow you to create an empty contact list for such applications, but it’s easier to simply not use suspicious software.
How often should you change passwords and privacy settings?
It is recommended to change passwords for Google and Samsung accounts once every 3-6 months or immediately after any suspicious activity. Privacy settings should be rechecked after each major system update, since new versions of Android often add new tracking functions or change the logic of old permissions.
