FREQUENTLY ASKED QUESTIONS

We are happy to answer most of your questions here.
1Can I manage multiple products in one account?
Yes, that is possible. You can order additional HiddenContacts from our shop. Once you start setting up your second product by scanning, you can easily add it to your existing account instead of registering again. Simply click on "Login" after entering the activation code.
2Do I need a separate subscription for each QR code/product?
No, private users only need a single subscription. The subscription applies to your entire account and covers an unlimited number of activated QR codes.
3Do I have to decide on a specific subscription during the purchase in the shop?
No, the additional features in the form of our optional subscriptions are only added after activating the QR code. You will be asked automatically.

Our optional upgrade packages: Basic – €0 per year: Receive unlimited messages via email & stay anonymous. Plus – €5.99 per year: Receive messages via WhatsApp, SMS, Discord, Threema, and Telegram. Premium – €11.99 per year: Includes everything from Plus, plus anonymous calls, scan history, temporary notes, and multiple recipient addresses.
