Why it works on people who know better
Scams don't beat you on intelligence. They beat you on pressure.
Urgency
You have eleven minutes before the warrant is executed. The panic isn't a side effect. It's the product.
Isolation
It's a confidential investigation, ma'am, don't discuss it with your family. Alone, there's nobody to talk you out of it.
This is why knowing about scams doesn't protect you from them.
How Kavach works
- 1
Bring it onto the call.
One tap when an unknown number rings. Kavach joins quietly and listens. The caller never knows it's there.
- 2
It follows what they're actually asking for.
Not the words — the shape. Authority, then panic, then isolation, then the ask. However politely it's wrapped, and however long they take to get there.
- 3
It warns you out loud, mid-call.
Spoken, in the language you think in, while there's still time to put the phone down. Not a notification you'll read tomorrow.
The moment it matters
A real digital arrest script, and where Kavach cuts in.

यह एक digital arrest scam है। पुलिस कभी वीडियो कॉल पर गिरफ़्तार नहीं करती। कोई पैसा मत भेजिए, फ़ोन काट दीजिए।
"This is a digital arrest scam. The police never arrest anyone over a video call. Don't send money. Hang up."
Every scam call is a ladder. Kavach cuts in before the last rung.
Kavach speaks the language you panic in.
English is the language you do business in. Under pressure, everybody goes home.

More on the way.
A thing that listens has to earn it.
It listens to them, not to you.
Kavach follows the stranger's side of the call. Your side is yours.
What it knows about you stays on your phone.
Your bank, your family's names, the numbers you actually use — Kavach keeps these to check a caller's story against, and they are never sent off your phone during a call.
You switch it on, per call.
It does not sit in the background waiting. There's no always-on microphone in this product.
Get Kavach before the next call.
We're opening early access in small batches so we can actually talk to the first people who use it. Tell us a little and we'll be in touch.
