Cookies and Local Storage are files with small amount of data which may include an anonymous unique identifier. Cookies and Local Storage are sent to your browser from a website and stored on your device.


You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent. However, if you do not accept cookies, you may not be able to use some portions of our Service. The same is valid for Local Storage.

We keep the information until you delete your account, and the information will keep in our backup archives for 90 days after the account is deleted, unless a longer retention period is required or permitted by law. We store data on servers in the U.S. in a reserved database with restricted access.



Data Security

The security of your data is important to us, but remember that no method of transmission over the Internet, or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your Personal Data, we cannot guarantee its absolute security.
