Why I'm redirecting to google.ae? Are any of your servers located in the Middle East?
When you are connected to Betternet you can check your current IP location using Betternet's status page or use any IP locator websites that you prefer. Here is an example: http://ip2location.com, But Google works much smarter than that!
Google prioritizes information of lots of users connected to its servers, and although we don't have any servers in the Middle East, we have lots of users living there. So for example when Google receives many requests from users in United Arab Emirates with an IP located in the UK, it marks the IP's location as United Arab Emirates and you are redirected to Google.ae. This does not endanger your connection safety and security at all.
