The internet is forever.
Your files and emails don't have to be.

Send documents and emails that self-destruct. Set viewing rules, track access, and permanently destroy everything when you're done. The email goes blank too.

Disappearing documents. Disappearing emails.

How it works

01

Drop it in

PDFs, contracts, photos, videos. Drag it into the box.

02

Set the rules

Timer, view limit, PIN, watermark. You control everything.

03

Send the email

They get a disappearing email with a secure viewing link.

04

It burns

Files destroyed. Email goes blank. No backups. Gone.

Tired of people sharing your documents with other people? And even worse, with AI?

Every file you email can be forwarded, downloaded, screenshotted, and fed into ChatGPT. You have zero control the moment you hit send. Burn Box changes that.

Who uses Burn Box?

Anyone who has ever said “please don't share this” while attaching a file to an email.

HR & People Ops

Offer letters & compensation

Send offer letters that can be reviewed but not forwarded to the whole team. Salary details stay between you and the candidate.

Legal

Contracts & settlements

Share settlement offers, discovery docs, or draft agreements with opposing counsel. Control who sees what and for how long.

Founders & Startups

Pitch decks & financials

Send your deck to investors and know exactly who opened it, how long they read it, and which pages they skipped.

Procurement & Sales

Sensitive RFPs & proposals

Share pricing, vendor comparisons, or proprietary proposals without worrying about them ending up in a competitor's inbox.

Real Estate

Appraisals & loan docs

Share inspection reports, purchase agreements, and financial documents with buyers or agents on a controlled timeline.

Healthcare

Patient records & referrals

Share HIPAA-sensitive materials with specialists or insurers. Auto-destruct ensures records don't sit in someone's downloads forever.

Finance & Accounting

Tax returns & bank statements

Share financial documents with your advisor or accountant. PIN-protected, time-limited, watermarked with their name.

Media & Entertainment

Unreleased scripts & contracts

Send unreleased creative work, talent agreements, or deal memos. If it leaks, the watermark tells you who.

Anyone

Anything private

Insurance claims, medical records, ID documents, tax filings. Anything you need someone to see but not keep.

Is it really gone?

Yes. When we say gone, we mean gone.

Can someone download the file?

No. Files are never sent to the browser. They are rendered server-side and displayed as protected image tiles.

Can they screenshot it?

We block screenshots, screen recording, keyboard shortcuts, right-click, and print. If they try, you get flagged.

What about the email?

The email itself goes blank. We serve the preview as a live image from our servers. When the box is destroyed, the image swaps to "This document has been destroyed."

Can anyone recover it?

No. Not us, not you, not anyone. Files are permanently deleted. No backups. No archives. That is the point.
