Google stores everything privately and here are the 10 important links (URLs) that will unlock everything Google knows about you. They are hidden somewhere deep inside your Google Account dashboard and they may reveal interesting details about you that are otherwise only known to Google. Let's dive in.

1. Google stores a list of usernames and passwords that yo have typed in Google chrome or Android for logging into various websites. They even have a website too where you can view all these passwords in plain text.:: Passwords.google.com

2. Google creates a profile of yourself based on the sites you visit, guessing your age, gender and interests and then uses this data to serve you more relevant ads. Use this URL to know how google sees you on the web.:: www.google.com/settings/ads

3. You can easily export all your data out of the google ecosystem. You can download your Google photos, contacts, Gmail messages and even your YouTube videos; head over the Google takeout page to grab the download links.::
www.google.com/takeout

4. If you ever find your content appearing on another website, you can raise a DMCA complaint with Google against that site to get the content removed. Google has a simple wizard to help you claim content and the tool can be used to remove websites form Google search results that are scraping your content.
:: support.google.com/legal

5. Your Android phone or the Google Maps app on your iphone is silently reporting your location and velocity(are you moving and if yes, how fast are you moving) back to Google servers. You can find the entire location history on the google maps websites and you have the option to export this data as the KML files that can be viewed inside Google Earth or even Google Drive.
:: google.com/maps/timeline

6. Create a new Google Account using your existing email address. The regular sign up process uses your @gmail.com address as your Google Account username but with this special URL, you can use any other email address as your username.
:: accounts.google.com/SignupwithoutGmail

7. Google and YouTube record every search term that you have ever typed or spoken into their search boxes. They keep a log of every Google ad that you have clicked on various websites, every YouTube video you have watched and, if you are a Google Now User, you can also see a log of all your audio search queries. Ok Google.
: history.google.com(Google searches)
: history.google.com/history/audio(Voice searches)
youtube.com/feed/history(YouTube searches and watched videos)

8. You need to login on to your Gmail Account at least once every nine months else Google may terminate your account according to their programme policies. This can be an issue if you have multiple Gmail accounts; so as a workaround, you can set up your main Gmail account as the trusted contact for your secondary accounts. Thus, Google will keep sending you reminders every few months to login onto your other accounts.
:: www.google.com/settings/account/inactive

9. Worried that someone else is using your Google account or it could be hacked? Open the activity report to see a log of every device that has recently connected into your Google account. You will also get to know the IP addresses and the approximate geographic location. Unfortunately, you cannot remotely log out of a Google session.
Myaccount.google.com/security

10. Can't locate your mobile phone? You can use the Google Device Manager to find your phone provided it is switched on and connected to the internet. You can ring the device, see the location or even erase the phone content remotely, You can even find the IMEI Number of the lost phone from your Google Account.
