Protect emails, phone numbers, signatures, bank details, and other sensitive information before sharing documents with AI.
Someone out there knows more about you
than you ever intended to share.
Your salary. Your ID. Your address. Your account number. It was there — in a file you sent — to someone who never needed to see it.

Remove what identifies you. Keep what AI needs.

Chhaya removes personal information while keeping the content AI needs for analysis.
✓ Identifiers removed
This agreement outlines consulting services, payment obligations, confidentiality requirements, intellectual property ownership, limitation of liability, and dispute resolution procedures.
Every PDF you share carries information the other person was never meant to see. Chhaya gives you control — permanently, before it leaves your hands.
"It doesn't matter what you do.
If you share documents — or upload them to AI — you need Chhaya."
See how quickly sensitive information can be removed before sharing a document.
The moment nobody warns you about
It happened to you.
You just didn't know.
You sent your salary slip to a recruiter. It had your full bank account number on it. You noticed only after you pressed send.
You uploaded a document to ChatGPT for help. Your Govt ID number, home address, and date of birth were on page two. You didn't scroll that far.
You forwarded a medical report to a relative. It had your insurance details, policy number, and home address printed on the header. You never read the header.
Once sent, you cannot take it back.
Most people only realise after they've already pressed send.
One payment. Yours forever.
You cannot unsend a file. But you can make sure the next one is clean before it leaves.
And it happened to others too
These are documented, confirmed incidents. Real people. Real data. Real consequences. None of them intended to expose anything.
A software bug — not hacking — caused users to see other users' chat history. The same bug exposed names, email addresses, and payment details of 1.2% of paid subscribers. It lasted nine hours before anyone noticed.
No one uploaded anything to hurt anyone. A bug decided who else saw it.
Each one was just doing their job. One debugged code. One fixed equipment. One transcribed a meeting. None of them meant to leak anything. Samsung banned ChatGPT company-wide the same week.
They didn't share a "document." They shared a file that happened to contain something they forgot was there.
The acting director of CISA — the agency responsible for US national cybersecurity — uploaded documents marked "For Official Use Only" into the free public version of ChatGPT. An internal security review was triggered.
If the person whose job is protecting national data didn't think twice — it can happen to anyone.

None of them were careless.
They just didn't check what else was in the file.
Don't wait for your name to be in the next report.
Billions lost. Six hours too late. Don't be the statistic.
Check the file before it leaves. That is all Chhaya does.
There Is A Choice Now
Every file you share from this moment on — you decide exactly what's in it. Not the AI tool. Not the recruiter. Not the person on the other end of WhatsApp. You.
One payment. One decision. Everything you share after this — protected.
One payment · Works offline · Your file never leaves your device
Before you share any file — with a person, an AI tool, a platform, anyone — Chhaya lets you find and permanently destroy the private information inside it. Not hide it. Not cover it. Destroy it at the file level so nothing can ever recover it. Your file stays on your device. Nothing is uploaded. Nothing is stored. Nothing leaves.
It also removes hidden metadata — the invisible information files carry about when they were created, on which device, by whom. Gone too.
Drop in any PDF, image, or scanned document. Works on files that are typed, printed, or photographed — any document you have.
Type up to 3 words at once — for e.g. search "John Smith Anderson" in one go, not three separate searches. You can also use Detect Common IDs to automatically find emails, PAN, GSTIN, Aadhaar, SSN, UK NI numbers and more — across every page, instantly. Chhaya shows you exactly which page each appears on and how many times.
One click. Every instance across every page — permanently removed. Or drag manually over any area. Zoom in to verify before you apply.
Save the whole document, just the current page, or only the pages you changed. Export as PDF or image. Share with confidence.
Instead of searching "John", then "Smith", then "Anderson" one at a time — type all three together. Works for names, addresses, or any three words you want to protect. Chhaya finds every word simultaneously, thereby saving time. Every match across every page.
Click once. Chhaya scans every page and automatically identifies structured IDs — using checksum validation so matches are mathematically confirmed, not guessed.
Other tools are built for businesses — monthly fees, cloud processing, features you never use. Chhaya does one thing: lets you control exactly what leaves your device. No subscription. No cloud. No compromise.
Chhaya processes every file entirely on your machine using your own CPU. No cloud upload. No server processing. No AI that reads your documents. Your client's PAN number is never transmitted anywhere.
The only internet activity: a one-time license validation when you first activate. After that, Chhaya works offline forever.
Many professionals think drawing a black box in a PDF editor makes information private. It doesn't. The original text often remains fully embedded in the file — visible to anyone who knows how to look.
Drawing black boxes in image editors — text data remains in the PDF layer beneath.
Highlighting with a black marker in PDF editors — the text can often be copied out directly.
Covering text with shapes or stickers — file metadata can still expose the original content.
Many PDFs still contain recoverable text beneath visual highlights.
Whether you're in India, the US, Europe, UK, or Australia — regulators are watching, fines are real, and "I didn't know" is not a defence.
No subscription. No monthly fee. No renewal. Every file you ever protect from today — covered by one payment.

Still not sure? Here is what people said the first time they used it.
Not sponsored. Not curated. Just what people actually wrote.
"honestly didn't think i needed this until i realised my last 3 salary slips had my full account number on them and i sent them to 2 recruiters and a bank. downloaded this immediately. does exactly what it says."
"i work in hr and we forward documents constantly. always assumed the person removed what they didn't want shared. now i use this before sending anything out. takes 2 minutes and i actually sleep better."
"good app, does what it says. the search result that shows page by page is really useful — i didn't realise my name appeared 11 times across 4 pages. only thing i'd want is a mac version, hopefully soon."
"uploaded a medical report to chatgpt last year for a translation. only afterwards realised my insurance number, policy details and home address were all on page 1. wish i had this then. using it for everything now."
"i'm a small business owner and i send contracts and invoices all the time. always worried about client data. $9.90 is nothing for the peace of mind. set it up in 5 minutes, works offline, no issues."
"my friend sent me a property document on whatsapp. it had his full address, id number and phone on every page. he had no idea. sent him this app the same day. now we both use it before sharing anything."

In Sanskrit and Hindi, Chhaya (छाया) means Shadow. Not darkness — protection. A shadow cast deliberately, over precisely what others should never see.
Every document you have ever shared had something in it that was never meant to leave the room.
Chhaya is built for that moment — before you press send. Cast the shadow. Share only what is yours to share.
"Privacy isn't about hiding.
It's about choosing who gets to see what's yours."
Every document tells a story about you. A salary slip tells your income. A medical report tells your health history. A property paper tells your wealth. Chhaya lets you share the story — without sharing every chapter.
One payment. No subscription. Works offline. Your file never leaves your device.
The next file you share — make sure they only see what you choose.
Once sent, you can't take it back. Protect it before.
