How has this not been taken care of already? This is concerning. The web.airdroid.com interface should really be working under HTTPS by default. I cannot understand how that's not already the case considering how sensitive the data transmitted can be. I am not and will not be using the web.airdroid.com interface until it implements HTTPS support. In the meantime, I will stick with the secured local lite connection.
AirDroid, this feature has been requested for years now...
