That's good that you decided to revive your wallet project and promote it on Stellar-related media, but maybe it's better to start with codebase update? As I can see from the Github repository, the last commit was more than a year ago. Since that time there have been two protocol updates, a few Horizon releases, and multiple SDK changes, so there is high probability that your wallet lacks new functionality at best and is potentially vulnerable at worst. Also have you checked SDF wallet listing guidelines (https://www.stellar.org/community/wallet-guidelines/)?
Dealing with other's people implies trust, especially given the fact that you have full access to the user private keys on the server side.
