Files cookie (or “cookies”) are small pieces of data that websites store on your device. They help sites remember your logins, language settings, shopping cart and other personal data. However, over time, cookies accumulate, take up memory, slow down the browser, and can pose a threat to privacy - especially if you use public Wi-Fi networks or share your phone with other people.

On Androiddevices, cookies are stored not only in browsers, but also in some applications (for example, Facebook, Instagram or banking services). Clearing them can solve problems with slow loading pages, authorization errors, or even eliminate advertising “garbage” that follows you around different sites. In this article we will analyze all possible ways to delete cookies on Android from standard settings to hidden functions for experienced users.

Why you need to regularly clear cookies on Android

Many users underestimate the importance of clearing cookies, considering them “harmless” files. However, there are at least 5 reasons to do this regularly:

  • 🛡️ Security: Cookies may contain data for auto-login to accounts. If the phone falls into the wrong hands, an attacker can gain access to your profiles on websites.
  • 🚀 Performance: Thousands of unnecessary cookies slow down page loading and increase traffic consumption.
  • 🎯 Privacy: Advertising networks (for example, Google Ads or Facebook Pixel) use cookies to track your behavior on the Internet.
  • 🔄 Site errors: Outdated cookies may cause failures during authorization or the correct display of content.
  • 📱 Saving memory: On devices with a small amount of internal memory (for example, Samsung Galaxy A10 or Xiaomi Redmi 9A) every megabyte counts.

According to company research NordVPN, more than 60% of users never clear cookies on mobile devices, although this takes no more than a minute. At the same time, 89% of respondents noticed that after cleaning the browser starts to work faster, and advertising becomes less intrusive.

📊 How often do you clear cookies on your phone?
Never
Once every few months
Every month
Only when problems arise

Google Chrome is installed on 90% Androiddevices by default, so let's start with it. The instructions are suitable for all versions of the browser, including the latest updates from 2026 to 2026.

To delete cookies in Chrome:

  1. Open the browser and click on the three dots in the upper right corner (⋮).
  2. Go to Settings → Privacy and Security.
  3. Select Clear history.
  4. Tick the boxes next to Cookies and site data (you can also check Cached images and files for complete clearing).
  5. Click Clear data and confirm the action.

If you want to delete cookies only for certain sites (for example, for VKontakte or AliExpress), do the following:

  1. V Chrome go to Settings → Site settings → Cookies.
  2. Click on All sites and find the required resource in the list.
  3. Tap on it and select Delete.

Close all tabs with important data (logins will be saved, but some sites will log out)

Check if you are using the "Synchronization" function (if so, passwords will be restored after cleaning)

Remember or save open tabs (they will close after cleaning)

Make sure you have a stable Internet connection (after cleaning, some sites will load longer)-->

⚠️ Attention: After clearing cookies, you will have to log in to your accounts on all sites again. If you use Google Password Manager, logins and passwords will be saved, but auto-login will be disabled.

Method 2: Delete cookies in other browsers (Firefox, Opera, Yandex)

If you use alternative browsers, the process clearing cookies will be similar, but with nuances. Let's look at the three most popular options.

Browser Path to settings Features
Mozilla Firefox ⋮ → Settings → Delete personal data You can select time range (for example, “In the last hour”)
Opera ⚙️ → Clear data → Cookies There is a “Quick clear” function on the main screen
Yandex Browser ⋮ → History → Clear history By default, clears cookies only for the last 24 hours
Samsung Internet ☰ → Settings → Personal data → Delete browsing data Supports clearing by category (for example, only social network cookies)

In Firefox there is an additional function - Tracking protectionthat automatically blocks some advertising network cookies. To enable it:

  1. Go to Settings → Privacy.
  2. Select Strict protection mode.
  3. Activate the option Delete cookies when closing.

⚠️ Attention: In Opera and Yandex Browser cloud synchronization is enabled by default. If you clear cookies on your phone, they will also be deleted on other devices connected to the same account.

Method 3: Completely clearing cookies through Android settings (for all applications)

Not everyone knows, but Android allows you to delete cookies not only in browsers, but also in all applications that use them (for example Facebook, Twitter, TikTok or banking apps). This method is more radical, but effective.

Instructions for Android 10–14:

  1. Open Settings → Applications.
  2. Click on the three dots (⋮) in the upper right corner and select Show system.
  3. Find the application Credential storage (or Credential Storage on English firmware).
  4. Tap on it, then select Storage and cache.
  5. Click Clear data and confirm the action.

This method deletes all saved passwords and auto-login data all applications, including system ones. Use it only if:

  • 🔐 You have forgotten the password for an important account and want to reset the saved data.
  • 📱 Are you planning to sell or transfer the phone to another person.
  • 🛡️ You suspect that your device has spyware installed that uses cookies for tracking.
What will happen if you clear the “Credential Storage”?

After this operation you will have to re-enter passwords in all applications, including:

- Social networks (Instagram, Telegram, WhatsApp)

- Banking applications (SberBank Online, Tinkoff)

- Mail clients (Gmail, Yandex Mail)

- Gaming services (Google Play Games, Steam)

We recommend that you save all important passwords in a safe place before cleaning (for example, in Google Password Manager or KeePass).

⚠️ Attention: On some firmware (for example, MIUI from Xiaomi or One UI from Samsung) the path to the credential storage may differ. If you do not find this section, use the search in the settings for “credential storage.”

Method 4: Automatically clear cookies using specialized cookies applications

If you are too lazy to manually clear cookies or want to automate the process, you can use third-party utilities. We tested 5 popular applications and selected the best:

Application Functions Pros Cons
CCleaner Cleaning cookies, cache, history, duplicate files Free version, Russian language, scheduled cleaning Advertising in the free version, sometimes deletes useful data
SD Maid Deep system cleaning, search "junk" cookies Finds cookies even in hidden folders, supports root access Complex interface for beginners, paid features
Files by Google Cleaning cache and unnecessary files, including cookies Official application from Google, easy to use Does not remove cookies from browsers (only system junk)
Norton Clean Clearing cookies, protection against trackers, memory optimization Good privacy protection, removes advertising cookies Requires registration, a lot notifications

We recommend SD Maid for experienced users and Files by Google for beginners. If you need maximum privacy, pay attention to Norton Clean —it not only cleans cookies, but also blocks trackers in real time.

To automate cleaning using CCleaner:

  1. Install the application from Google Play.
  2. Open it and go to section Cleaning.
  3. Select Applications and mark
