What are cookies
Cookies are small piesces of text sent by your web browser by a website you visit.
A cookies file is sotred in your web browser and allows the Service or a third-party to
recognize you and make your next visit easyier and the Service more useful to you.
Cookies can be"persisten" or "session" cookies.
Why are Cookies Used?
Cookies are a convenient way to carry information from one session on a website to another,
or between sessions on related websites, without having to burden a server machine with massive amounts of data storage.
Storing the data on the server without using cookies would also be problematic because it would be difficult to retrieve
a particular user's information without requiring a login on each visit to the website.
If there is a large amount of information to store, then a cookie can simply be used as a
means to identify a given user so that further related information can be looked up on a server-side database.
For example the first time a user visits a site they may choose a username which is stored in the cookie,
and then provide data such as password, name, address, preferred font size, page layout, etc. - this information would
all be stored on the database using the username as a key. Subsequently when the site is revisited the server will read
the cookie to find the username, and then retrieve all the user's information from the database without it having to be re-entered.
Who Can Access Cookies?
When a cookie is created it is possible to control its visibility by setting
its 'root domain'. It will then be accessible to any URL belonging to that root.
For example the root could be set to "whatarecookies.com" and the cookie would then be available to sites
in "www.whatarecookies.com" or "xyz.whatarecookies.com" or "whatarecookies.com". This might be used to allow
related pages to 'communicate' with each other. It is not possible to set the root domain to 'top level' domains such as '.com' or '.co.uk'
since this would allow widespread access to the cookie.
When you use and access the Service, we may place a number of cookies file in your web browser.
to store your preferences, to enable advertisements delivery, including behavioral advertising.
We use both session and persistent cookies on the Service and we use disfferent type of cookies to run the Service.
Essential cookies. We may use essential cookies to authenticate users and prevent fraudulent use of user accounts.
A third-party cookie is one that is placed on a user’s hard disk by a
Web site from a domain other than the one a user is visiting.
As with standard cookies, third-party cookies are placed so that a
site can remember something about you at a later time. Both are typically
used to store surfing and personalization preferences and tracking information.
Third-party cookies, however, are often set by advertising networks
that a site may subscribe to in the hopes of driving up sales or page hits.
Third-party cookies are often blocked and deleted through browser
settings and security settings such as same origin policy; by default,
Firefox blocks all third-party cookies. Blocking third-party cookies does not
create login issues on websites (which can be an issue after blocking first-party
cookies) and may result in seeing fewer ads on the Internet.
Blocking third-party cookies increases user privacy and security but has created
a problem for consumer tracking / ad serving firms, which often place ads that follow
users around the Web. Mozilla’s decision threatens to make an impact equivalent to the
market share of Firefox in their bottom line. Combined with the removal of third-party cookies
by other means, some firms estimate that 40 percent of all third-party cookies are removed. Some
firms argue that this will affect small business users who rely on third-party consumer tracking and ad serving for revenue.
As it affects their survival, firms have tried to undermine these changes by using other
techniques such as respawning cookies, Flash cookies, entity tags (Etags) and canvas fingerprinting.
