8 amazing personal things smartphones know about you - Your smartphone knows a lot more about you than you can imagine.

So, with the data that smartphones have about their users, they can make advertisers offer personalized information.

And it is that metadata is that data that speaks of data. That is, they describe the contents of the files or the information in them.

In this sense, they allow you to explain details about your communications and, in turn, reveal behavior patterns and routines in an inconspicuous way.

No matter which mobile you choose, you're giving a lot of information every time you swipe the screen.

In fact, they know where you travel, what music you listen to, or who you talk to.

8 amazing personal things smartphones know

Below are 8 amazing things your mobile phone knows about you.

- Every place you've been

Both Android and iPhone have internal tracking devices that quite accurately record where you've been the last few days.

In addition, it saves them in a detailed map and you can even check the hours of the day in which you visited this or that site.

To check, in the case of iPhone, you must access the Privacy Options of your phone.

Under Settings, tap Privacy.

Then choose location.

Click on System Services and choose important places.

In the history you can see the last cities you visited and if you click on each place, you will see a detailed list and map.

Also, if you click on each of the zones, you can see when you were there.

Remember that some apps don't work if you don't enable localization.

In fact, the first time an app needs to access your location information, you'll receive a notification asking for permission but you can disable it at any time.

- Everything you said to Siri.

Apple collects Siri data to "better understand you and recognize what you say" through the software license agreement, according to Reader's Digest.

So, from the way you pronounce words to the trends in your Siri searches, Apple knows a lot more than you think about yourself.

Any Apple user who has used the "hear Siri" feature will have wondered at some point if the virtual assistant is constantly listening to you.

However, Apple devices do not send any information to the cloud until a match occurs in the "Hey Siri" pattern.

- Your personal IDs.

In 2018, the smartphone manufacturer OnePlus was accused of sending personal information of users of their devices to a Chinese server belonging to the company Teddy Mobile, which specializes in telephone contact list solutions, according to Europa Press.

Access codes to the devices, as well as IP addresses or telephone numbers were included in the list of delivered data.

From the company assured that they used the information with the aim of improving the user experience.

Thus, she was not charged with violation of privacy.

In addition, the Facebook and Cambridge Analytica scandal also raises the possibility that other tech companies are collecting data from their users.

- Your passwords

Auto-Fill is a tool that makes your life more comfortable.

This way, your device will remember your passwords instead of having to enter them.

In addition, if these are sites you visit regularly, the Autorelleno can be quite convenient and will save you time.

However, do you really want Google, your smartphone and some of those websites to store your information?

Maybe your answer is no.

In that case, write your passwords in a document on your computer or on paper and you will feel much more secure.

- Every message you send

If you're an iPhone user and you delete conversations from your text messages or iMessage constantly, chances are they still exist.

Apple saves messages in encrypted form for a limited period of time before they are deleted.

This is only to "make sure they are delivered and read correctly," according to Reader's Digest.

However, since Apple have not revealed what it means "a limited period of time". So it can be minutes but also years.

- All the information you've given to Google

Android devices work with Google apps: Chrome, Playstore, Gmail, among others.

So, when you log in to your Android with your Google login details, your phone will be linked to all your other server accounts.

Once you've logged in, your mobile device has access to everything you do with Google, including the length and type of your calls, your location, and more.

You can download the data that Google has from you but it does not imply that it is deleted from its servers.

To do so, simply access this link and you will be able to export all the data that Google has about you.

- How fast you walk

Your iPhone not only tracks your location but also records the arrival and departure time.

So, calculate how long it will take you to get to the places and then send you notifications when you notice a trend.

However, you can disable System Services in the Settings.

Just make sure that the apps you're using, like Uber or Facebook, also have Location Services turned off.

- All the information you've given to your apps

If you go into your smartphone's settings, you can control how much information the apps you download receive.

But some like Facebook require you to check your settings within their app.

However, if you turn off location services for many of them, your Mobile will prevent you from using them.
