Files cookies (cookies) are small text files that websites save on your device to store data about sessions, preferences and authorization. They accumulate in browsers, applications, and even system processes, which over time can lead to slowdowns, privacy leaks, or site rendering errors. For example, if you notice that Android They accumulate in browsers, applications, and even system processes, which over time can lead to slowdowns, privacy leaks, or site rendering errors. For example, if you notice that Google Chrome it starts to slow down when opening tabs or Instagram it constantly asks for a re-login, clogged cookies are to blame.

Clearing cookies on Android differs from desktop systems: there is no single “control center”, and each browser and application stores data separately. Moreover, on devices with Android 12+ additional restrictions on access to system files have appeared, which complicates manual cleaning. In this article we will analyze all current methods for deleting cookiesincluding hidden settings that are not shown in standard instructions.

It is important to understand: deleting cookies is not always favorable. On the one hand, this frees up to 50-200 MB memory and resets ad network tracking scripts. On the other hand, you will have to re-enter logins on sites, set up personal recommendations in YouTube or TikTok, and some web services may temporarily block your account due to “suspicious activity”. Therefore, you should clear cookies selectively (selectively), and not en masse.

Why clear cookies on Android?

There are three main reasons, and each is associated with different aspects of the smartphone:

  • 🔒 Privacy: Cookies contain data about your pages visited, search queries and even geolocation. Advertising networks (like Google Ads or Facebook Pixel) use them for targeted advertising. Cleaning clears these "traces".
  • ⚡ Performance: On devices with 4/64 GB memory (for example, Redmi 9A or Samsung Galaxy A12), a clogged browser cache can take up to 1-2 GB, which leads to lags when multitasking.
  • 🔄 Error resolution: If the site does not open, shows outdated data or gives an error ERR_CACHE_MISS, the problem often lies in damaged cookies.

However, there is a downside: after cleaning, some sites may:

  • 🔄 Require re-authorization (even if you saved the password in Google Password Manager).
  • 📱 Reset interface settings (for example, dark theme on Twitter/X or language on AliExpress).
  • 🛑 Temporarily block an account due to "unusual login" (relevant for banking services like SberBank Online).
⚠️ Attention: On devices with Android 14+ some system applications (for example Google Play Services) can automatically restore some cookies after a reboot. This is due to the function Scoped Storagethat restricts access to application files.

How to clear cookies in Google Chrome

Google Chrome is the most popular browser on Android. (installed on ~70% devices), so let's start with it. Unlike the desktop version, mobile Chrome does not have a separate option "Delete only cookies" - you will have to clear them along with the cache. Here are step-by-step guide:

  1. Open Chrome and tap on the icon ⋮ (three dots) in the upper right corner.
  2. Select History → Clear data.
  3. In the section Basic check the boxes:

    Disable synchronization in Settings → Synchronizationif you do not want to clear data on other devices-->

    Clearing cookies in other browsers (Firefox, Opera, Edge)

    The algorithm for clearing cookies in alternative browsers is similar, but there are nuances. Let's look at the top 3 popular options:

    Browser Path to settings Features
    Mozilla Firefox ⋮ → Settings → Delete personal data You can delete cookies without clearing the cache. Supports Containers (isolated sessions).
    Opera ⚙️ → Clear data → Advanced Has a built-in VPNthat can block some trackers Cookies are cleared along with the data Opera Turbo.
    Microsoft Edge ... → History → Clear data Synchronizes with Windowsaccount. Supports Immersive Reader, but cookies are cleared only in batches.

    1. Go to Settings → Privacy.
    2. Activate the option Clear personal data when exiting.
    3. Tick in the list Cookies and Site data.

      4. In Opera and Edge there is no similar option, but you can use Incognito mode (private window), where cookies are deleted automatically after closing tabs. However, please note that in this mode the following are not saved:

      • 🔖 Bookmarks
      • 📥 Downloaded files
      • 📋 Browsing history

    Google Chrome|Mozilla Firefox|Opera|Microsoft Edge|Brave|Other-->

    Deleting cookies through Android system settings

    If you want to clear cookies all applications (including browsers and instant messengers like Telegram Web or VK, you can use system tools. This method is suitable for devices on Android 10+where access to application files is limited.

    Method 1: Through Settings → Applications

    1. Open Settings → Applications.
    2. Tap on ⋮ → Show system (if you need to clear system applications).
    3. Select a browser or application (for example, Facebook), then go to Memory → Clear data.
    4. Check Clear cache and Clear all data (the second item will delete all application settings, including cookies).

    On devices with root access you can delete cookies manually through the file manager (for example, Root Explorer):

    Go to /data/data/com.android.chrome/app_chrome/Default/Cookies

    Delete the Cookies file (a reboot may be required)

    What is root access?

    Root access is superuser rights in Android that allows you to change system files. Getting root can void the warranty, break OTA updates and create vulnerabilities for viruses On modern devices (for example, Samsung Galaxy S23 or Pixel 7). It is almost impossible to get without unlocking the bootloader, which erases all data.

    How to clear cookies in applications (not browsers)

    Many applications (social networks, instant messengers, games) also use cookies to store sessions and preferences. For example, TikTok saves data about videos watched, and AliExpress - about the shopping cart. Cleaning here works differently than in browsers.

    General algorithm:

    1. Open Settings → Applications.
    2. Select the desired application (for example, Facebook or Amazon Shopping).
    3. Go to Memory → Clear cache.
    4. If you need to reset all data (including cookies), click Clear all data.

    For popular applications there are nuances:

    • 📘 Facebook/Instagram: Cookies are stored in Menu → Settings → Account → Data applications. Here you can delete the activity history, but not the cookies themselves - for this you need to clear the data through the system settings.
    • 🎮 Games (for example, Clash of Clans or PUBG Mobile): Cookies here are responsible for saving progress. Clearing them will lead to losing the gameif it is not linked to an account Google Play Games or Facebook.
    • 🛒 Marketplaces (Wildberries, Ozon): Clearing cookies will reset the cart and browsing history, but will not delete saved delivery addresses (they are stored on the server).

    1. Open the application and go to Settings.
    2. Find the section Security or Privacy.
    3. Select Clear browser data (in VK) or Reset settings (in OK).

    Automatic clearing of cookies: tools and applications

    If you are tired of clearing cookies manually, you can automate the process using third-party utilities. They are divided into three types:

    1. Memory optimizers (for example, CCleaner, SD Maid): They delete cache and cookies on a schedule, but require access to accessibility (may be a security risk).
    2. Browsers with tracking protection (for example, Brave, DuckDuckGo): Automatically block some cookies and clear them when closed.
    3. VPN with a cleaning function (for example, ProtonVPN, NordVPN): Some services offer an option CleanWebthat deletes trackers and cookies after the session.

    An example of setting up automatic cleaning in SD Maid:

    1. Install the application from Google Play.
    2. Run and provide access to memory.
    3. Go to Trash → Autorun.
    4. Activate the option Clear cache when memory is low.
    5. Add system applications to exceptions (for example, Google Play Services).

    For users Android 13+ there is a limitation: cleaning applications require permission POST_NOTIFICATIONSto run in the background. Without it, automatic cleaning will not work trigger only when you manually launch the utility.

    Application Cleaning function Cons
    CCleaner Cleaning cache, cookies, history Aggressive advertising, requires a lot of permissions
    SD Maid Deep cleaning (including system files) Paid version for full functionality
    Brave Browser Auto-cleaning when closing Not all sites work correctly
