About this app

Imagine a world:
...where you always know the real identity and trustworthiness of the person at the other end regardless of which online platform you use.
...where you set the minimum information criteria for the people you engage with whether it is for a temporary or permanent relation – and whether it is for personal or business use.
...where you have full control over what information you are sharing, with who – and with the ability to stop sharing instantly.
...where your phone book is always updated even if your contacts change their phone number, address or email.
You are in charge. Welcome to Handzhake.

How Handzhake works:
- Create your profile by using your local eID service (e.g. MitID for Denmark, BankID for Sweden etc.) within a minute.
- Use preset or custom “cards” (like a business card) to quickly create relations where you both agree on which information to share (e.g. phone number, e-mail, home address, social media links etc – and possibly personal information like age, relationship status and children names etc.). All information sharing is always based on a fully consensual “show me yours and I’ll show you mine”-policy.
- All active relations are automatically synchronized to your contact database so that you never have to update a phone number, address, email etc again. Instead of providing your new phone number to all your contacts, just change it in Handzhake and all your contacts will be updated instantly.
- Use the “Nearby” feature to connect with people in close proximity whether you are at a meeting, conference, dinner, date etc.
- Rate your relations (and be rated) on different parameters with the ability to use or request those ratings across other online platforms
- Let your future friends, trading or dating partners know who you are and how you are rated at first contact and skip the initial, time-consuming trust-build phase – and limit the number of human disappointments by setting your own criterias for whom you interact with.
