How cookies can track you (Simply Explained)

Cookies can be used to invade your privacy and track you around the internet. But what are cookies and how do they work? They were initially invented to make our lives easier and are used to keep us logged in and to store things like shopping carts and preferences on our computers instead of on servers.
However, clever companies can use cookies to track us around the internet. It can help them to build a profile of users and sell more targeted advertisements.
In this video, I'll show you how cookies are working and why they're useful. Then we'll explore how cookies can be used to track people and finally, we'll discuss how you can prevent being followed.

Good explanation! Learned cookie in uni web course but didn't understand how cookies could track you because of the domain scope restrictions...This makes it clear

You either die a hero or you live long enough to see yourself become the villain-- cookies

[@caiqueandrade6259]

Awesome explanation. Thanks!

[@GauravPatel87]

To add to our privacy protection, modern browsers like chrome and firefox have settings that automatically clear cache and cookies when we close the browser, so next time when we open a website, it's all fresh.

[@simplyexplained]

Yes and besides these they are also adding protection against fingerprinting. This technique doesn't require cookies and is actually used more and more!

[@suleimanshaibu3087]

Well done your explanation is simple and it makes sense. Well done again

[@jairunet]

Excellent, and thank you for another simple explanation 🙇‍♂

[@alexonyshko730]

[@maheshgvp7735]

I had this doubt for a long time, how the hell can facebook/google track our habits and show relevant ads. Today I got the answer, thanks

[@mickey5370]

Hey there Savjee...I'm curious as to who creates/edits your videos? And which program is used for the animated graphics? Thx and keep up the beautiful video content. We appreciate you

[@simplyexplained]

I make them myself. One man channel ;)

[@mickey5370]

That's awesome - kudos! What are your tools of choice?

[@Hexoindiaplus]

Mickey San Miguel 4c

[@WilliamSkimming]

This is good as it covers how the 3rd party process works and what defines a 'good user experience' ...I like it.

[@SRY4EatnyourSandwich]

Very Nice. Like that style

[@StAlfonzo87]

Nice explanation. The question I'm left with is how much information is available in these tracking cookies? Like, how bad can the invasion of privacy get?

[@uploder247]

Just block third party cookies.

[@nighttime9539]

Nice explanation.

[@vaibhavsaxena7932]

very nicely explained

[@ThamaraiselvamT]

So private windows are fresh start so no cookies hence other can't track you. (unless you login Facebook or Google). Amazing explanation. Thanks😊

[@dimitargetsov9690]

Great ,man! GREAT!! Thank You!

[@rwingender]

Nicely done. It would have been good to explain what cookies store in an ecomm site.

[@KpopSociology]

Very well-said!

[@rishimitranath]

Interesting Savjee

[@ifaceTech]

Great channel, I've learned a lot. You're very clear and to the point.

[@eintyp4389]

That was Awsome video thx keep it up.

[@v3le]

Ghostery privacy ad blocker says: don't trust anybody, except us!

[@henryhargraves4184]

Not surprised , that something was invented to be convenient turned into something that abuses privacy.

[@ariostaba664]

6:36 Twitter cookie I am kidding nice video!

[@Rudra-go6us]

outstanding content!!!

[@jlotica]

Thanks for this content

[@SouravTechLabs]

Great video!

[@Sajanoberoy]

Legendary explainer😘. Love from India🇮🇳

[@NaturaWild123]

Thanks for the vid, perfect explanation. Just one thing can you make a video about JavaScript and how to use it for security?

[@mibrahim4245]

What do you mean by the "session cookie"? What I know is that session is on the server side and never stored on your computer that it contains sensitive data like users particular data fetched from the database! .. while cookies are stored on your pc and can be seen by anyone has access to that computer and they last for longer times than sessions that are destroyed at the browser closure or a sign out button! So what did I miss here? I hope you answer.. thanks

[@baddhidurgarao]

Simply good 👌

[@dduarte80]

Thanks!

[@chashlovers6027]

Which App do you use Buddy to Create These Awesome Videos??

[@ThomasDubuisson]

Thx! Great video and content! By any chance, would you share the script of this video or is it available on your website? Thanks again!

[@simplyexplained]

Nope

[@ocamlmail]

Thank you for video. Fb knows that I visit some page even if I don't interact with like button(click on it), or because of it's presence on page?

[@marscoding]

Very good video. I watched some other video explain cookies but they only say third party cookies, not how third party cookies work make me confusing

[@amwalonline]

Good job deserve thanks 😊 and like

[@swaggyskye]

Hi ! I'd like to know when will the cookies be sent to the third-party apps from the example of blog to facebook. When the blog has facebook cookies and I enter the blog's website? or when I click on the like button? thanks!

[@Bitternov]

Good job.

[@XDFcooler]

We should eat more Cookies, they're very nice.

[@diablocomvn]

My Lord. It's so much useful

[@danialatash9815]

So useful

[@emilioortega9487]

I didn't get in the minute 3:55, so when the blogs communicate with Facebook servers then the blogs in that communication send the information of the cookie (of the blog) stored in the user browser to facebook ???

[@leonhannemann5231]

Sänks for the Information now i feel me much safer!

[@lorenz4594]

3:50 doesn't the website need to access facebooks cookies to send them? it needs to get them somehow in order to send them. you said that websites can't access cookies from other websites though. what am I missing here?

[@GK-rl5du]

Hi @savjee firstly thanks a lot for the wonderful easy to digest content, secondly can you please share the resources that helped you in putting together this content, so anyone interested in diving deep into the topic can follow on.

[@simplyexplained]

The sources for my videos are always noted in the description (link to my website)

[@GK-rl5du]

I thought I checked the description box... but apparently not. Anyway thanks for pointing it out.

[@Gorky25]

Does that mean I can copy-paste someone's cookie from his computer and run it on my computer? Because there are all that it needs to be logged in? Or cookie can detect IP address and prevent it?

[@user-vh8hd6ru3s]

What's the music on background, please?

[@alin7303]

even if you press i accept one time, you can still be hacked? And even if you close your tab its still possible?

[@arleneabilay1127]

Thanks i was on my pc then i saw tracking cookie it was getting my information

[@kazuki32_z75]

even your Ip and other bunch of privacy from phone or pc can track by cookies?

[@jamescarroll9981]

Good video it learning people to take action and switch off cookies, which in will reduce the size of the tech giants buy cutting there revenue

[@janiyahaning5292]

How do you switch it off?

[@helenarichard]

Every website now demands our permission to use cookies... And we give our permission... we haven't got a foot to stand on anymore now... the government makes things even worse. We are being recorded wherever we go, whatever we do, whether our phones are on or off...

[@neha7714]

Hi with same dusi the resolution is decreasing and increasing, is this a cookie theft ?

[@florincaroli3173]

Hello! I understood the Facebook example, but what about Google? How does a website that has Google Analytics can track me? Thank you!

[@this-is-bioman]

Unfortunately this still doesn't explain how a 3rd party cookie knows where it's coming from. I understand that it's being send to another address, but how does the 3d party know the source of the cookie? Is the browser sending some kind of a refferal together with the cookie? I cannot imagine any other way for them to find out about the website I'm on.

[@wenwu2476]

just blocked 30 trackers as soon as i clicked this vid lmfao

[@projectjt3149]

So what does Basic Attention Tokens factor into this?

[@ghosty70001]

am using google chrome and my facebook account keeps logging out automatically ... and it does the same with internet explorer. It does that only with my facebook acount but it doesn't do it with other facebook accounts. Why does this happen? can you help me?

[@MP-vf8qz]

We should be able to vote on these trackers, many companies are getting very rich selling all of our information ( maybe doing malicious acts with this info).

[@cup_check_official]

so does that mean cookie monster can track me as well?

[@simplyexplained]

Absolutely! Everywhere you go!

[@68walter]

Software Man , i hope your last name is not cook, Lol.

[@lizgawin899]

@@simplyexplained hi i'm having some trouble with my cookie tracker thing and need advice, see usually there's a shield thingy blocking trackers and ads but youtube froze up and i was forced to restart with the power button, NOW i'm locked in a fight with my blocking options and they keep coming back no matter what i do, should i just have the local computer guy install an ad-blocker or do you have any advice because i'm just fed up.

[@SuiSSe-Torture-Prisonniers-CH]

Savjee, thx for the video; the following video series in three parts "The Swiss Beast - Home of the Devil" will explain you, who this enemy is, who want to track you.

[@rahulramteke3338]

Cookie AutoDelete: Allow me to introduce myself

[@robinmcguire6010]

Your explanation was helpful, however, if I give you a thumbs up aren't I exposing myself to KZbin's cookies? ha ha

[@JBudOner]

Thank you for not being biased! I realize I'm in the minority here being in favour of cookie tracking, and its frustrating seeing the pitchforks raised w/out any reasonable discussions behind it

[@sodthelotayou3712]

Pitchforks are being raised because permission is not being sought and you're naive if you believe that no one will, if they can, take liberties. Take it you don't care about the concept of privacy.

[@Jerepaukan]

I was watching something on KZbin and I left it open hen went onto fb and than I saw the exact same content creator posting the SAME VIDEO I was watching

[@vaultdweller123]

the last time im this early, cookies are delicious, we eat them :)

[@helenarichard]

what about duck duck go? And can I use Safari on Android?

[@nurmuslihah585]

This is so creepy. I'm an android user. Can I download Safari and will not get tracked?

[@ihebbelhaj1380]

1:50 🤣🤣🤣🤣🤣 yourSubscribers ++

[@flamablegas6308]

This is why I disable them in the browser settings, also I have 3 anti-trackers

[@charan_75]

If I am not logged into Facebook and visited a blog that contains a like button from fb. Would Facebook still know that I visited that website?
