TavKey

TavKey helps trusted family members check whether they are seeing the same shared signal during suspicious calls.

Scammers can pretend to be someone you know. TavKey gives your trusted group a simple shared signal that changes over time. When a call feels unusual - for example, someone asks for money, a password, or an urgent favor - you can ask for the current TavKey signal.

If the other person has been added to your trusted group, they can open TavKey and see the same signal.

How it works
Create a trusted group, then add members while you are physically together. Once paired, each phone shows the same rotating signal.

Designed for simplicity
TavKey is built to be calm, clear, and easy to use. No accounts, no social feed, no complicated setup.

Privacy first
TavKey is designed to avoid collecting personal information such as family names or contact lists.

Use TavKey when a call feels off
If someone claims to be a family member and asks for something sensitive, ask them for the current TavKey signal before you continue.

TavKey does not detect, block, or report scams. It is a verification aid. Always use your own judgment and never share passwords or any sensitive information if you are unsure it's safe.
