TavKey gives your trusted family a simple shared signal that changes over time. When a call feels off – someone asks for money, a password, or an urgent favor – you can ask for the current signal. If they are part of your trusted family, they can open TavKey and see the same one. Below are the basics, common questions, and how to reach us.

Getting started

1. Create your family

Open TavKey and give your family a name. Your phone becomes the first trusted device, and the live signal is visible right away.

2. Add family in person

Adding a trusted phone happens while you are together in the same room. Open TavKey on both phones, hold them close together, and the app pairs them for you – there are no long codes to type and nothing to scan. Being together helps you make sure you are adding the right person and keeps your family circle private.

3. Verify any caller

When a call feels off, open the app and ask what your family’s signal shows right now. A real family member will always know. A scammer never will. If you are still unsure, hang up and call back using a number you already trust.

Common questions

How does TavKey work?
TavKey shows a private signal – such as a color, an image, and a number – that only your trusted family phones can see. It changes regularly, and all trusted phones show the same signal at the same time. When someone calls and you are not sure it is really them, ask what TavKey shows right now.
How do I add a family member?
You add a family member in person. Open TavKey on both phones, hold them close together in the same room, and the app pairs them for you. TavKey guides both phones through a short verification step so you know you are adding the right device.
Do I need to be together to add someone?
Yes. To add a trusted phone, you and the other person need to be together in person. This prevents mistakes and keeps your family circle private. (It is also a nice excuse to visit your parents or grandparents.)
Do I need the internet to see the signal?
No. Once your phone has joined the family, it shows the current signal on its own using your device clock. No connection is needed to check it during a call.
Is my family data private?
Yes. TavKey is designed to store as little information as possible – no account, no contact list, and no family names collected. Your private family signal is shared only with the trusted phones you explicitly add. See our Privacy Policy for details.
Can TavKey guarantee a call is safe?
No app can guarantee that. TavKey helps you check whether the caller has access to your family’s private signal. It adds one more layer of confidence – if you are still unsure, hang up and call back using a number you already trust.

Troubleshooting

The two phones will not pair

Adding a member happens over a short-range connection between two phones in the same room. If pairing does not complete:

The signals do not match

The signal changes on a regular schedule, so both phones need a roughly correct clock. Make sure each phone is set to update the date and time automatically. If the signals still differ, the other phone may not have been added to your family – and if a caller cannot show the right signal, treat the call with caution.

I switched to a new phone

A trusted device is tied to the phone it was set up on. On a new phone, set up TavKey again and add it in person, just like the first time.
