The on-device digital life guardian
Your digital life is under constant attack. Watch us stop it.
Paste any message, link or screenshot, or let it connect a text, a call and a payment request into one coordinated-scam verdict. Checked right on your phone, never the cloud, with the reason attached. Tap a message to see it work.
Watch a scam lunge for your cursor. Centinal catches it in time. Click anywhere to set one off.
Glass-Box, not black box
Caught before you tap, with the why attached.
No mystery score. Every flag names the trick it matched and the tell that gave it away, in plain English, so the lesson sticks for the next one.
Measured in the open: 96% recall · 92% precision on a published detection corpus.
The part no one else does
A scam rarely arrives one message at a time.
A text, then a call, then a UPI request, choreographed to rush you. Centinal chains them into a single coordinated-scam read, entirely on your phone.
The proof
Nothing you check ever leaves your phone.
Don’t take our word for it. Cut the internet and watch it keep working.
Set it up for me
Not a checklist. A guardian that sweeps.
One tap runs a live pass across your real protections, fixing what it safely can and flagging the rest in plain English. It never flashes a false all-clear.
Personas
Protect the people you love.
One tap tunes Centinal for whoever holds the phone, without hovering over anyone’s shoulder.
Me
Quiet by default. A second opinion in two taps when a message feels off.
Parent
Bigger text, louder warnings, gentle explanations for every flag. They can also hand you any message to check.
Child
Game-bait and gift-card tricks flagged in kid-plain language, before pocket money leaves the house.
Straight answers
Honest by design.
Is Centinal free?
Yes. Scam checking, screenshot scanning, Protection Rings and Safari ad blocking are all free. No account, no ads, no paid tier in this release.
Does it read my SMS or calls?
No. It never reads your messages or calls. It checks only what you paste, screenshot or share into it. Even that is processed on the phone, never uploaded.
Does it work without internet?
Yes. The check runs entirely on the device, so it works in airplane mode. Try it yourself in the proof section above.
Does it block YouTube ads?
No app can. Apple doesn’t allow any blocker to touch YouTube or in-app ads on iOS. We block what’s blockable in Safari and are upfront about the rest.
Already been scammed?
Act within the first 24 hours: call 1930 (India’s cybercrime helpline) or report at cybercrime.gov.in and ask your bank to freeze the transaction.
Is it a guarantee?
No. It is a second opinion, an aid. It can miss a clever scam or flag something harmless. Never share an OTP or PIN on its say-so.
Turn “I’m not sure” into “now I know.”
The quiet guardian for every phone you love.
Free. On-device. Blocks ads in Safari too. Made in India, built in the open.
A second opinion, not a guarantee. Never share an OTP or PIN on its say-so.
