Cookies are small text files that are saved on your device when visiting websites. They help sites remember your settings, logins, and preferences, but they can also pose a privacy risk. On Androiddevices, cookies accumulate in browsers (Chrome, Firefox, Samsung Internet), social networks and even some applications, which over time slows down the system and increases the risk of data leakage.

In this article you will find 5 proven ways to delete cookies on any versions Android — from Android 8 Oreo to Android 15. We will look at how to clear cookies selectively (for example, for only one site) or completely, why you should not delete them too often, and what to do if after clearing the sites no longer work correctly. You will also learn how to automate the process using special applications and why manual cleaning through Settings is not always effective.

Why do you need to delete cookies on Android?

Cookies perform useful functions: storing logins, shopping carts in online stores, language settings and personalized recommendations. However, their accumulation is fraught with several problems:

  • 🛡️ Security threats: Cookies can contain authorization data (tokens, sessions), which attackers can intercept through vulnerabilities in the browser or Wi-Fi network.
  • 🐢 Slowdown: Thousands of cookies take up space in the device’s memory and increase page loading time.
  • 🎯 User tracking: Advertising networks (for example Google Ads or Facebook Pixel) use cookies to track your behavior across different sites.
  • 🔄 Data conflicts: Outdated cookies may cause errors when authorizing or displaying content (for example, "403 Forbidden").

The company's research NordVPN showed that the average user Android accumulates up to 500+ cookies per month, of which only 10% is really necessary for comfortable work. The remaining 90% is “garbage” that can be safely deleted.

⚠️ Attention: If you use two-factor authentication (2FA) on websites, deleting cookies may require re-entering the code from SMS or the authenticator application the next time you log in.

Method 1: Clearing cookies through browser settings (Chrome, Firefox, Samsung Internet)

The simplest method is to delete cookies directly in the browser. Instructions for popular applications:

Google Chrome

  1. Open Chrome and click on ⋮ (three dots) → History → Clear data.
  2. Select tab Advanced.
  3. Set the time range (for example, All time).
  4. Tick the boxes Cookies and site data (the rest of the items can be left blank).
  5. Click Delete data.

Mozilla Firefox

  3. Click Delete data.

Samsung Internet

  1. Open the browser, go to ⋮ → Settings → Personal data → Delete browsing data.
  2. Select Cookies and site data.
  3. Confirm deletion.

This method allows you to clear cookies selectively for specific sites. For example, you can go to Chrome in Settings → Privacy → Content settings → Cookies → All cookies and data sites, enter the name of the site (for example, vk.com) and delete only its files.

If you want to clear cookies for all applications (including browsers and social networks), use system tools:

  1. Go to Settings → Applications.
  2. Click on ⋮ (three dots) → Show system ones (if necessary).
  3. Select a browser (for example Chrome) or application (for example Facebook).
  4. Click Storage → Clear data (this will delete all application dataincluding cookies, cache and settings!).
  5. For selective clearing, select Clear cache (less radical, but does not delete cookies).

This method is suitable if:

  • 🔍 You want to reset the application settings to factory settings.
  • 🚫 The application does not work correctly due to damaged cookies.
  • 📱 You have little space on your device and need to free up memory.
⚠️ Attention: Clearing application data Android System WebView can lead to malfunctions of some sites and applications. Do this only if you are sure of the need!

Method 3: Using specialized applications for cleaning

If you need to regularly delete cookies and other junk, it is more convenient to use third-party utilities for this task:

Application Functions Pros Cons
CCleaner Clearing cookies, cache, history, APK files Automatic scheduled cleaning, analysis of used space Advertising in the free version, sometimes deletes useful data
SD Maid Deep cleaning of system files, including cookies Works without root, finds "garbage" in hidden folders Complex interface for beginners
Files by Google Deleting unnecessary files, including browser cookies Simple interface, built-in "Cleaning" function Does not support selective cleaning for individual sites

Example of working with CCleaner:

  1. Install the application from Google Play.
  2. Run analysis (button Analysis).
  3. Go to the tab Privacy.
  4. Tick the boxes Cookies and Browser history.
  5. Click Clear.

Warning: Some applications (for example, Clean Master) aggressively delete data, which can lead to crashes. Check reviews and ratings in Google Play.

💡

Before mass clearing cookies using third-party applications, create a backup copy of important data through Settings → System → Backup.

Method 4: Manually deleting cookies through a file manager (for experienced users)

Cookies are stored in system folders Androidand can be deleted manually. This method is suitable if:

  • 🔧 You want to delete cookies only for a specific site.
  • 📁 You need to free up space without affecting other data.
  • 🛠️ Standard methods did not work (for example, due to a browser crash).

Instructions:

  1. Install a file manager with access to system folders (for example, Solid Explorer or FX File Explorer).
  2. Go to the path: 
    /data/data/com.android.chrome/app_chrome/Default/Cookies

    (for Chrome) or

    /data/data/org.mozilla.firefox/files/mozilla/default/cookies.sqlite

    (for Firefox).

  3. Delete file Cookies or cookies.sqlite.
  4. Restart the device.
⚠️ Attention: To access the folder /data/data/ required root access. Without them, you will not be able to see these files. Incorrect deletion of system files can cause the browser to crash!
What to do if, after manually deleting cookies, the browser stops working?

If the browser gives an error after deleting files, try:

1. Clear browser data via Settings → Applications.

2. Reinstall the browser.

3. Check the integrity of files using the command adb shell pm clear com.android.chrome (connection to a PC is required).

Method 5: Automatically clear cookies when exiting the browser

If you want cookies to be deleted automatically after closing the browser, configure this in the settings privacy:

In Google Chrome:

  1. Go to Settings → Privacy → Clear history.
  2. Activate option Delete cookies and site data when exiting.

In Mozilla Firefox:

  1. Open Settings → Privacy → History.
  2. Select Firefox will: Use your settings.
  3. Check Clear history when closing Firefox and configure exceptions.

This method useful if you:

  • 🖥️ Use public Wi-Fi and want to minimize the risk of data leakage.
  • 🔒 Work with confidential information (for example, in banking services).
  • 🚀 Do you want to speed up page loading due to the absence of unnecessary cookies.

However, keep in mind that with this approach you will have login to your accounts again each time on sites.

💡

Automatic clearing of cookies is useful for security, but is inconvenient if you often use sites with authorization (social networks, mail, Internet banking).

What to do if, after deleting cookies, sites do not work?

Sometimes clearing cookies leads to problems: sites do not open, give authorization errors or show outdated content. Here's how to fix it:

  • 🔄 Refresh the page (F5 or refresh button in the browser). This often helps to download new cookies.
  • 🔑 Login again to your account - many sites require re-authorization after clearing cookies.
  • 🌐 Check your date and time settings on the device. Incorrect data may block the creation of new cookies.
  • 🛠️ Clear the DNS cache: 
    Type in the Chrome address bar: chrome://net-internals/#dns

    Click "Clear host" cache"

  • 📋 Add the site to exceptions (if you use automatic cleaning). In Chrome this is done in Settings → Privacy → Content settings → Cookies → Add exception.

If the problem persists, try:

  1. Open the site in incognito mode (cookies are not saved in it, but problems with them are excluded).
  2. Use another browser (for example, Brave or DuckDuckGo, which block tracking by default).
  3. Checking a site on another device may be a problem on the resource side.

FAQ: Frequently asked questions about deleting cookies on Android

Is it possible to delete cookies for only one site without affecting the rest?

Yes, most browsers have such a function. For example, in Chrome go to Settings → Privacy → Content settings → Cookies → All cookies and site data, find the site you want (for example, ok.ru) and delete its cookies separately.

Why do some sites open slower after clearing cookies?

Cookies speed up page loading by saving some data locally. After they are deleted, the site has to load everything again. Over time (after 2-3 visits), the speed will return to normal, as the browser will create new cookies.

Is it safe to use applications to automatically clear cookies?

Yes, if these are proven utilities from Google Play (for example, CCleaner or SD Maid). However, avoid little-known apps with suspicious permissions (for example, access to SMS or contacts). Always read reviews before installation.

How to delete cookies in applications (for example, VKontakte or Instagram)?

In social networks and instant messengers, cookies are deleted along with the application cache. To do this:

  1. Go to Settings → Applications → [Application name] → Storage.
  2. Click Clear cache and Clear data (second item will reset all settings, including login!).

For Instagram i Facebook you can also use the "Log out of account" function - this will delete the current session cookies.

Is it harmful to frequently delete cookies for your phone?

Frequently clearing cookies (for example, once a day) does not harm the device, but can cause inconvenience:

  • You will have to log in to your accounts again.
  • Some sites will load slower.
  • Personalized recommendations (for example, in YouTube or TikTok) will be reset.

Optimal frequency - every 1-2 weeks or as needed (for example, if you notice suspicious activity).
