Google now expires cookies after 2 years, not 31

By | July 16, 2007, 12:08pm PDT

Google relies on what they call their PREFS cookie to remember information about visitors — their cookie is set to expire in the year 2038, and some privacy advocates say that violates the privacy of users. That said, users have complete control over the cookies on their machine through browser settings already, but Google decided to cut the expiration time 29 years to just 2. Privacy watchdogs should have something good to write about[PDF] now, but they probably won’t.

In the coming months, Google will start issuing our users cookies that will be set to auto-expire after 2 years, while auto-renewing the cookies of active users during this time period. In other words, users who do not return to Google will have their cookies auto-expire after 2 years. Regular Google users will have their cookies auto-renew, so that their preferences are not lost. And, as always, all users will still be able to control their cookies at any time via their browsers.

On the other hand, I don’t still understand why they need a two year expiration if they are auto-renewing them. Why not set it to something like 6 months — if a user doesn’t visit Google at least once in that amount of time, they aren’t a regular user so why bother remembering them? What do you think? Are you more comfortable with cookies that expire in two years?

Google is evil.
ibabadur1 16th Jul 2007
I don't allow cookies for the Google site.

Especially if you sign up for gmail and sign in to your account. Then they can tie your searches together with your email from any PC you log into and search from. Its like 1984 was their blueprint.

Google is a data mining operation pure and simple. From the data they collect is where they derive wealth. So it seems obvious that they want as much information about people as possible. They have your thoughts in blogs and email, your interests through the search and maps, and now what you work on through their hosted apps. The whole Google experience is keyed around them gaining insight into every aspect of your life which they can get their hands on. Crazy people could wonder if Google is the ultimate CIA front.

This is a public relations stunt
Daniel Brandt 16th Jul 2007
In the first place, Google's announcement repeats the fiction that the purpose of the cookie is to remember user preferences. In fact, the real purpose of the cookie is to plant a globally-unique ID on the hard disk for profiling purposes. You do not need a unique ID at all to get user preferences from a cookie. In fact, you don't even need a cookie to remember user preferences. The preferences could be sent in the URL along with your search terms.

Anytime Google uses the word "preferences" in the same sentence as "cookie," you know they're hiding something.

Secondly, Google's announcement suggests that they will either push the expiration date ahead two years whenever your browser accesses any of Google's sites that read this cookie, or they will do it when they detect that your cookie is about to expire. Apparently they will keep the same unique ID in the cookie, or at least be able to associate the old ID with any new ID that they issue.

This new technique is not a two-year expiration date by any rational description. Instead, it is practically a guarantee that your cookie will expire two years after your hard disk fails and you toss it into the dumpster.

Is it even possible for someone who uses the web regularly to avoid any and all Google sites for two years running? I doubt it, which means that this announcement of a two-year expiration date is essentially meaningless.

You still have to block Google's cookies using whatever tools are available, if you wish to protect your privacy. Google's new technique does nothing to change this, and their announcement is nothing more than a public relations stunt.

Google Cookies
andy@... 17th Jul 2007
I can't see how it makes a difference whether cookies are 310 years or 10 seconds duration or even chocolate coated! When you sign in surely a new cookie is baked there and then isn't it?
Maybe a user could choose a duration based on their personal expectation of return to Google (just so that they dont HAVE to sign in)....Andy

Since most browsers make it extremely easy to clear private data with 2 to 3 mouse clicks.

Google is definitely not the only offender of overly long cookie retention.

How about the ZDNet cookies. I just received a new cookie after logging in with ZDNet name "purs_3" that expires in 2036-12-30. How about "XCLGFbrowser" cookie. Why does that one hang around for 10 years?

How about msn.com? The cookie "MC1" that I just received today doesn't expire until 2021-10-04.

It is funny how everyone slams Google when everyone else does the exact same thing.

However, I think this is a non-issue since most web browsers allow the clearing of all private information with 2 or 3 mouse clicks. Many even allow you to clear all cookies on exiting the browser.

Safe browsing practices.
kraterz 17th Jul 2007
Why not set your browser to clear cookies on each exit? It's trivial on firefox. It's a couple of keystrokes on opera.

That said, there's no valid reason for cookies at all, except to maintain state information for, say, an online banking session. Even webmail can be done without cookies, you can use yahoo mail that way. Simply block cookies when not needed.

ZDNet is worse. I've never gotten a "We detected a problem with your cookie settings" on Google. Sites like ZDNet make it hard to surf safe.



happy
I keep getting this message on google with both IE and Firefox
We've detected a problem with your cookie settings.

Almost impossible to use google right now because of this
