Technologies We Use
We use cookies and other similar technologies, such as local and session storage, to ensure everyone using the Service has the best possible experience of its features. Specifically, we may use these technologies to:
- improve your experience;
- track and analyse usage and other statistical information; and
- measure the effectiveness of our ads.
If you choose not to activate these technologies or disable them later, you may still access our Service, but your ability to use some features or areas of those offerings may be limited.
Cookies and Storage
A cookie is a small text file that is placed on your hard drive by a web page server. Cookies contain information that a web server can later read in the domain that issued the cookie to you.
Additionally, we use local and session storage. It is a technology very similar to cookies. The data is stored in the user’s browser. However, it has a larger size limit. The local storage is stored in the browser until its clearing. Session storage, on the other hand, expires at the end of the session on the website.
Some cookies and local storage will only be in usage if you use certain features or select certain preferences, and some cookies are essential to the Service and will always be used.
We use several types of cookies and local storage:
