Onyu is a brand new mobile platform for sharing your personal information with the people and businesses that need it; a secure place to manage all of the everyday details that you use to administer your life.

Onyu acts as a state of the art mobile address book, allowing you to stay in touch with all of your contacts without having to manually maintain contact lists. It allows each user to keep their own information up to date and share it with whoever they choose. The result is a beautifully simple way to stay in touch and keep up to date. No social networks required.


What’s more, all of your information is held encrypted in our cloud. This means whenever you log in to a new device, your information and all of your contacts will instantly be available to you. And when we say encrypted, we really mean encrypted. Unlike other services, our application encrypts your data using state of the art client side technology. This means that we have no way of accessing your information when it lands on our servers, even if wanted to. We simply do not hold the keys to unlock it. Only you hold the key and only you know your password. This means we cannot read your data, we cannot sell your data and we cannot use your data to pester you with advertising.

Above all we believe passionately that your information belongs to you! Not anyone else. And only you should have the ability to control who can access it. This belief underpins everything we do. Your privacy is our top concern!

We hope you enjoy using the application. Its early days but we would love to hear what you think. We will be working really hard over the next few months to bring you bug fixes and improvements on a regular basis and we will be working towards a release for the upcoming Windows 10! Your feedback will be taken into account and used to direct future developments so please get involved. We’d be really grateful for you support.

Team Onyu.
