After seeing your concern I also looked into it but it seems to be a scam site. Google play store, appstore and extension links are provided on their website but I could not find any application of the site from google play store there. Although I haven't tried the other two, such scam sites that don't have good reviews should be avoided. If services are taken from these sites, there is a high probability of accepting the scam. One of my concerns is that it was a big mistake to use a scam wallet without any reviews, There are lots of good wallets in the market you should have accepted one of them especially which are most renowned. What is the best wallet for storing Bitcoin?
