Everything inside, all free

One app. Every angle covered.

Everything below runs on the phone and shows its work and it is all free in this release. It reads a text, a call and a payment request as one story, sweeps your whole phone in a tap, and stands by you before, during and after. A second opinion, not a guarantee. It never reads your messages; it checks only what you hand it.

Scam Check

Paste any SMS, chat message, email or link that feels off or share it straight from any app. The share sheet even reads screenshots and QR codes, including UPI payment QRs. You get an instant verdict in plain English: what looked wrong, which trick it matches, what it wanted you to do. It is tuned for India’s UPI, KYC, courier and digital-arrest plays, in English and Hinglish. If it is a payment link, it names the payee and the amount before you ever open the app it targets. It even chains events together, an SMS, then a call, then a UPI collect request, into one coordinated-scam verdict, entirely on-device.

Measured in the open: 96% recall and 92% precision on a published detection corpus.

The ambient win

Scan a screenshot

People already screenshot the scary message before they think to ask about it. Pick that screenshot and Centinal reads the text out of the image, right on the phone, with Apple’s Vision engine and no retyping, then runs the same check. Your parents already do step one; the app does the rest.

No retypingImage never leaves the phone

Ask Centinal

After a verdict, keep asking: “Why is this risky?” “What do I tell my father?” Grounded answers plus the one safe next step, answered right on the device, even in airplane mode. On a recent iPhone, Apple’s on-device model phrases it even more simply and the check itself needs no AI hardware.

UPI & number lookup

About to pay someone you don’t know? Check the UPI ID or phone number against the known-scam list first, on-device, before the money moves. And when a payment link or QR is in play, it decodes the real payee and amount for you, then repeats the one rule that matters: a UPI PIN only ever sends money, it can never receive it.

The daily ritual

Protection Rings: close them and stay safe.

Two honest rings, like a fitness tracker for your digital safety. Shields up is your standing setup, with blockers on and protections configured. Staying sharp resets weekly, so you see the new scam of the week and keep your streak alive.

Before, during and after the scam.

Most scam apps only judge a message. This one trains you before, verifies during and stands by you after.

Scam fire-drills

Practice on realistic fakes: spot the tells, reveal the trick, learn the one-line “vaccine.” Inoculation, not an ambush.

The five big plays

Playbooks for the scams that matter in India, digital arrest, KYC, UPI refund, courier and job-task. It tells you what happens, plus your move.

Verification Hub

Verify a person, company or lender through the real authority’s own register, never a search result. The authority verifies; we simply take you there.

Real-number finder

Don’t call the number from the message. Don’t trust a searched one either. Look up the institution’s verified customer-care line here first.

Voice-clone defence

A guide to AI-voice and deepfake scams, plus the family safe-word plan that beats a cloned voice asking for money.

Password breach check

See if a password has appeared in known breaches. Only the first 5 characters of a hash ever leave the phone, never the password.

“I’ve already been scammed”

Calm, ordered steps for the worst hour: who to call, what to freeze, plus India’s 1930 cybercrime helpline. The first 24 hours matter most.

Scam of the week

A weekly briefing on the line fraudsters are using right now. It keeps your check fresh and your Staying-sharp ring honest.

Digital Safety Check-up

A guided check-up of your phone’s real protections, what’s on, what’s off, plus the one tap (or exact setting) that fixes each.

Photo privacy scan

Before you share a photo, an on-device scan flags documents, IDs and location data hiding inside it. Nothing is uploaded.

Link inspector

Paste a link and it reads the address itself, punycode look-alikes, brand impostors, shorteners, throwaway domains, without ever opening the page.

Complaint & grievance hub

When something goes wrong, it builds a filing-ready complaint from your own incident log, pre-filled for 1930, the NCRP, Chakshu and your bank, in the right order.

My incident log

Every high-risk flag is kept on-device as a private, exportable record, so you have the evidence and the timeline if you ever need to file.

The 60-second pause

Before you pay, share an OTP or add a new payee, a gentle cooling-off nudge steps in. Real banks never rush you; urgency is the tell.

Privacy-policy summariser

Paste or screenshot a privacy policy and it reads back, in plain English, what the company sells, shares, tracks and keeps, worst first, with the exact line that says so.

Name-on-the-web check

Sort what the internet shows about your name into likely-you, maybe and not-you. A name match alone is never treated as “you.” The sorting is on-device.

Data-broker removal guide

Per-broker: what they hold, the opt-out page and the exact steps to get yourself taken down, plus the India route through Results-about-you and a DPDP letter.

Username sweep

An opt-in check of where a handle you use shows up across the web, so you can find and close the accounts you forgot about.

Data-deletion letters

Generates a ready-to-send DPDP or GDPR deletion request. Nothing is submitted for you; you send it, so nothing about you leaves the phone.

Travel hardening

A guided seven-door pass before you travel: SIM PIN, auto-join off, Find My, message previews, juice-jacking, Lockdown Mode and a TAFCOP check after.

Caregiver alerts Rolling out

Link a parent’s phone so a high-risk flag on theirs can reach yours, privately, so they never have to judge a scam alone. Ships as Apple grants the permissions.

And it blocks ads, seriously.

The original job, done properly and free in this release. Filtering happens in Safari on your phone, no analytics, no tracking SDK, no server seeing your browsing.

~47,000 rules, four blockers

Four stacked Safari content blockers cover ads, trackers and annoyances, byte-budgeted to stay fast within iOS limits.

Finishes the job

A Safari extension hides leftover ad slots, defuses “turn off your ad blocker” walls and auto-answers cookie nags, always Reject, never Accept.

Tap-to-zap

A stubborn element survives? Tap it once and it’s hidden for good on that site. One-tap allowlist for sites you want to support.

“Is it working?”

A built-in self-check proves your blocking is live and a “shows its work” counter reports what was actually hidden. No guessing.

Everything here is free.

No paid tier, no trial, no account, in this release.

Some capabilities, automatic unknown-sender SMS flagging, scam-call heads-up, system-wide blocking, are rolling out as Apple approves them; they are not shipped yet and we say so rather than pretend.

An aid, not a guarantee

It can miss a clever scam or flag something harmless. Treat it as a second opinion and never share an OTP or PIN on its say-so.

It never reads your messages

The check sees only what you paste, scan or share into it and even that never leaves the device. No contacts harvested, ever.

No app blocks YouTube ads on iOS

Apple doesn’t allow any blocker to touch YouTube or in-app ads. We block what’s blockable in Safari and are upfront about the rest.

A clear line for the online bits

Almost everything runs on-device. The few checks that must reach out, breach lookup, some verifications, are opt-in, off by default and logged, and never folded into the “nothing leaves your phone” promise.
