Google Remembers More than You Realize

One of the least obvious and most ubiquitous collectors of information are the online services we choose to use.

None demonstrate this fact more clearly than Google.

As we go about our online activities, Google maintains a surprisingly detailed history of our activities. Most people don’t realize just how detailed it is, or how long it’s kept.

More interestingly, Google’s one of the good players, as it actually exposes this history to us, and even allows us to clear it if we want.

My Activity

It’s been called several things over the years, most commonly “web history”. Today, it’s referred to as “My Activity”, since, as we’ll see, it covers much more than web or search history.

Try it right now. Visit:

My Activity Signin

Sign in with your Google account.

A word about privacy

Near the top of the resulting page will be a statement from Google about who can see the information we’re about to explore.

Only you can see this data...

Only you can see this data.

It’s worth reviewing Google’s privacy policy by clicking on the “Learn more” link. That’ll take you to what I consider to be a somewhat “salesy” page that tells you why data collection is good for you. Near the bottom are the links to meatier pages:

The privacy "sales page"

My assumption is that Google can and will make any information it has on you available to law enforcement when compelled to do so. They have a record of fighting such requests, which is a very good thing, but I don’t think it’s safe to assume that they can and will win every such case in every jurisdiction.

Recent activity first

I logged in and was immediately presented with my recent activity.

My Activity

There were 226 items collected so far today, including the following categories:

  • Chrome, my browser, was responsible for most of the items recorded.
  • Android activity (from my phone) was included.
  • Search is a separate category.
  • Ads (It’s unclear exactly what this refers to. I’d not clicked on any ads.)
  • Image Search, which indeed, I had been using earlier this day.
  • YouTube. I’d forgotten, but I’d viewed a YouTube video embedded on another site earlier in the day.

Clicking on any of those categories filtered the results.

Search Activity

That’s my search history immediately prior to beginning work on this article1.

The full list of products

I used my search history as my example above, but Google keeps records across almost all of its products. As of this writing, the full list you can filter on includes:

  • Ads
  • Android
  • Assistant
  • Books
  • Chrome
  • Developers
  • Goggles
  • Help
  • Image Search
  • Maps
  • Maps Timeline
  • News
  • Play
  • Play Music
  • Search
  • Shopping
  • Video Search
  • Voice & Audio
  • YouTube

That list will naturally change over time.

Speaking of time…

History: lots and lots of history

In addition to filtering by the “product” used, you can examine your information by date.

The user interface to specify dates is cumbersome2. My activity log dates back to at least 2006. That’s a full decade of my online activity that Google has in its records.

Now, multiply that data by the number of Google users, and you have some idea of the breadth of data Google has on their hands.

Controlling and deleting your activity

On the left-hand side of the My Activity page are a couple of important links.

Activity controls lets you decide what information will and will not be collected at a high level.

Location History

Data collection defaults to being “on”. You can opt to turn off specific sections — like the Location History shown above — or you can turn all of them off, if you like.

The assumption is that this turns off actual persistent data collection. Cynics might argue that the data might still be collected, and all we’ve done is restrict our own access to it. There’s no way to know for sure.

Delete activity by allows you to delete the log of your activity by category or by date.

Is it time to panic?

My intent here isn’t to scare you.

It’s no secret that Google can, and obviously does, keep all this information. It’s perhaps one of their biggest assets.

My purpose in pointing all this out to you is simply to raise awareness of how much information we “give away” in our daily lives online. Any online service we use has the ability to record our interactions with them. Some do. Some don’t.

Google is upfront about it, making these details of their records easily accessible. As I said, in my opinion, they’re actually one of the good guys when it comes to this kind of thing. Other companies and services don’t publicize the information they keep, and I know of none that make it as easily reviewable.

By now, it should be doubly clear how important the security of your Google account is. Should anyone else gain access to it, they could capture this information as well. Whether that’s a problem is something only you can say.

2: Cumbersome, as in awful. Abysmal. Horrific. Like they don’t want you look back too far because it involves a lot of clicking to get there.

  1. If you are not paranoid, The Google is your friend. When I want the hours of a restaurant, The Google doesn’t give me every darn restaurant of the same name, just the ones near me, at least on the first page. But, if I am planning a trip to Peoria, after a few searches, the Peoria results come up first. If I visit a site and want to go there again after a few days have blurred my memory, The Google corrects my misrememberation (as well as my spelling).

  2. You say, “Sign in with your Google account.” What if you don’t have a Google account? Is Google still saving everything?

    • Yes. Google saves everything whether or not you have a google account. It’s even very likely that you do have a google account and just don’t know it.

    • They save much, yes, but this article is mostly aimed at people who have Google accounts and are unaware of how much is being saved — and accessible to them.

  3. I just checked my activity. The only records shown are seven visits to You Tube over the past four years. My only account now is my gmail account. This is checked every time is use my POP client and occasionally by webmail but I see no record of that. I deleted the account I used to use with Google+ some time ago when I found from Google Analytics that a Russian server had been used to make ten second visits my picasaweb site just before my registered credit card was twice used fraudulently. Google closed down picasaweb a couple of months after that.
