Cookie Policy
Every cookie this site uses or allows, and how to switch off the optional ones.
Last updated
This page lists every cookie WebCresto uses or allows, what each one does, and how to switch off the ones that are optional. It is a companion to our privacy policy.
What a cookie is#
A cookie is a small text file a website asks your browser to store. Next time you load a page, the browser sends it back. That is the entire mechanism. Cookies cannot read files on your computer or run programs — but because they persist between page loads, they can be used to recognise a browser over time, which is why advertising uses them.
Cookies this site sets itself#
WebCresto sets exactly one cookie of its own.
| Name | Purpose | Lifetime | Type |
|---|---|---|---|
wcsess |
Holds a random session identifier. Makes the security token on comment and contact forms work, and stops a page refresh from counting as a new view. Contains no name, email or browsing history. | Until you close your browser | Strictly necessary |
That is the complete list. There is no tracking cookie, no preference cookie and no analytics cookie set by this site directly.
Cookies set by Google advertising#
Advertising pays for this site, and those ads are served by Google AdSense. Google and its partners set their own cookies, which we neither control nor read.
| Set by | What it is for | Type |
|---|---|---|
| Google AdSense | Choosing which ads to show, limiting how often you see the same one, and measuring clicks and impressions. | Advertising |
| Google advertising partners | Ad selection and fraud prevention, depending on which partners participate in a given ad auction. | Advertising |
Google publishes the full technical detail in its policy on how it uses data from partner sites.
Analytics#
If analytics are running on this site, the provider will set its own cookies to distinguish one visit from another and record which pages were viewed. We use this to see which guides get read, not to identify people. You can block analytics cookies in your browser with no effect on how the site works.
Turning cookies off#
Advertising cookies#
The most direct control is Google's own:
- Google My Ad Center — turn personalised advertising on or off across Google's network.
- aboutads.info/choices — opt out of many third-party vendors at once (US).
- youronlinechoices.eu — the European equivalent.
Turning off personalised ads does not remove advertising. You will still see ads; they will just be chosen without using your browsing history.
In your browser#
Every major browser can block or delete cookies. The setting usually sits under Privacy or Site Settings. Look for "cookies and site data" — most browsers also offer a "block third-party cookies" option, which stops advertising cookies while leaving the session cookie working.
What breaks if you block everything#
Reading works perfectly with all cookies blocked. The one thing that stops working is posting a comment, because the anti-forgery check on the form depends on the session cookie. If you block cookies and a comment will not submit, that is why.
Do Not Track#
Browsers can send a "Do Not Track" signal. There is no agreed standard for how sites should respond to it, and most do not. We do not track you across other websites regardless of the signal — but the advertising cookies described above still follow Google's policies, not this browser setting. The opt-out links above are the reliable route.
Changes#
If we add or remove a cookie, this page is updated and the date at the top changes. If you spot a cookie on this site that is not listed here, please tell us — that is a mistake worth fixing.
