If you have been browsing with your mobile for a while, it is normal for the system and apps to accumulate lots of data, including the Cookies and cache, which store preferences, sessions, and even content to speed up loading. Knowing how to clean them up when necessary helps you resolve errors, gain privacy, and recover space, without complicating your life.
On Android the process is simple and with a few taps you can delete cookies from browsers, manage third-party apps, delete data from apps that store local information, and, if necessary, review what's stored in your Google account. Below is a comprehensive guide with all the steps and options you need to leave your phone as good as new.
What are cookies and what role does the cache play?
Cookies are small files that sites save on your device to remember preferences, keep you logged in, or offer personalized content and adsThere are two types: first-party cookies (from the site you're visiting) and third-party cookies (from integrated services such as ads, widgets, or images from other domains).
The cache, on the other hand, stores fragments of pages (for example, images or static resources) so they open faster next time. It's helpful, but if it accumulates too much it can cause loading errors, take up memory, and slow down your phone. If you use Chrome, you can see how speed it up on Android.
What happens when you delete cookies and cache?
When you clear cookies and cache, some website settings are reset and you will have to log in again on the sites you were previously connected to. Additionally, certain content (images, scripts) will be downloaded again, so you may notice some pages are slightly slower upon first access.
If you use Chrome with sync turned on, clearing data won't force you to sign in to your account again. Google account synchronized, and your preferences will be restored to all your connected devices. It's a convenient way to make sure you don't lose everything after the cleanup.
Keep in mind that, although cookies make life easier, they also allow for very detailed profiles to be built about your usage. On public Wi-Fi networks, an attacker could try to exploit identifying cookies to impersonate sessions, so cleaning with some frequency adds points in privacy.
How to delete cookies on Android with Google Chrome

Chrome is the most common browser on Android. To delete cookies and other browsing data, the steps are quick and straightforward. This way, you'll get rid of those files and fix potential loading or formatting issues on websites that aren't working as they should, reinforcing the security of your browser. your privacy on the go.

You can allow or block third-party cookies according to your preferences. This affects embedded content such as ads, players, or widgets from other domains, and has a direct impact on Personalization and tracking.
In Chrome for Android, go to "Settings" > "Privacy and security" and look for the options related to third-party cookies. There you can choose whether to allow or block them. Remember that, in Incognito mode, Third-party cookies are blocked by default, which reduces cross-site tracking.

It's also possible to add exceptions for specific domains. In the list of allowed sites, enter the domain address; if you want to cover an entire domain at once, you can use a pattern like ejemplo.com, which will include subdomains of the type servicio.ejemplo.com. This way you fine-tune the control and only you grant access to those who really need it.

Blocking, exceptions, and advanced protection of third-party cookies
If you're concerned about tracking, you can block all third-party cookies. Please note that some features will no longer work (e.g., embedded logins or embedded players). Compensate by creating exceptions for trusted sites or limiting blocking to incognito mode.
In Chrome's advanced settings, you'll find options to enhance your privacy: blocking third-party cookies completely, a list of sites that can use them, or sending a "Do Not Track" request. Make sure to periodically review your exceptions and remove the ones you no longer need.
