Save the proof
Add the purchase record, serial number, warranty, agreement, certificate or service record.
Sealed the day you save it — checkable years later.
Keep the records that matter
Anything you own.
Save the proof. Pass it on.
One private place for the records that matter about the things you own — electronics, appliances, vehicles, valuables, software and everyday gear. Keep the history while you own it. Share or pass it on when needed.
Every file you save is sealed with a dated digital signature — so years later, anyone can check it hasn't been changed. Not even by one dot.

The problem is simple
You own the thing.
But where is its history?
A receipt is buried in email. A warranty card is in a drawer. A service bill is somewhere in WhatsApp. A year later, when you actually need it, finding the proof becomes the problem.
ProofSave keeps the important records connected to the things you own.
Why not the usual places?
Storing a file is easy. Proving it is real is the hard part.
Now that AI can fake any bill in seconds, a forwarded photo or a file in a folder proves less and less. Sealed proof is different.
Google Drive / Photos
"It's free and everywhere." — Drive stores a file. ProofSave seals it, searches inside it, and hands a buyer the history without your address.
Email to yourself
"It's in my inbox somewhere." — Searching 4,000 mails for "invoice" isn't proof. A sealed record with serial and warranty date is.
WhatsApp gallery
"Everything's already there." — A forwarded bill photo is easy to edit. Ours carries a dated seal that shows if it ever changed.
The shoebox of paper
"Paper is real." — Paper fades and can't travel to a buyer in another city. A sealed photo can be checked years later.
"Is this official, like DigiLocker?"
We're not the government and don't pretend to be. DigiLocker suits documents the government issued. ProofSave keeps the bills, warranties and history of the things you buy — with proof they haven't been tampered with.
Not just receipts
The things you own have records too.
Save the documents, dates, numbers and history you may need months or years from now.

One simple habit
Save it now. Thank yourself later.
ProofSave is useful at the moment you buy — and often more useful months or years later.
2
Use it when needed
Open the record when making a claim, arranging a repair, proving a purchase or finding an old document.
Share only the information you choose to share.
3
Pass it on
When you sell or hand something over, transfer its useful recorded history to the next owner.
Ownership transfers are included with Lifetime.
Private by design
The record can move. Your private life doesn't.
ProofSave separates useful asset records from personal account information. When an item changes hands, only the records intended for transfer are made available to the next owner.

Protection, in plain sight
Built like it matters. Because it does.
Every protection stated plainly — including what's still on the roadmap.
Every file is sealed
Each document gets a dated cryptographic seal the moment it's saved. Anyone can verify a file is unchanged since that day — in their own browser, no upload needed.
AES-256 encryption
Shared proofs are encrypted end-to-end in your browser (AES-256-GCM). Even we can't read them.
SSL/TLS everywhere
Every connection to ProofSave travels over encrypted HTTPS, enforced by HSTS.
One-time keys, hashed
Proof and transfer links use random 256-bit keys — stored only as SHA-256 hashes. Keys can't be forged or recovered.
No public file URLs
Your documents are never reachable by link. They leave the vault only when you, logged in, ask for them.
Hardened by policy
Strict content-security, clickjacking and download-safety protections on every page — on by default, not an add-on.
Abuse-resistant
Brute-force throttling on every sensitive action, with a full audit trail of what happens in your account.
No trackers. Ever.
No third-party analytics, ads or beacons. Your data is never sold or shared — it's not our business model.
Your data, portable
Export every file and record anytime. No lock-in, no ransom — leave whenever you want with everything.

A new kind of record
Don't just keep the receipt.
Keep the story.
Purchase proof is only the beginning. Over time, an item can collect warranties, service records, repairs and ownership changes. ProofSave keeps those useful records together.

Years from now, you'll be glad you saved it.
The receipt or document you almost lost today might be exactly what you need tomorrow. And every proof you save is sealed and checkable — even years from now.
