Your Files Are
Actually Private

We use proper encryption and zero-knowledge architecture so your documents stay yours. Here's exactly how we keep nosy people (including us) out of your business.

Your files are encrypted and secure

Unique Keys (Only You Have Them)

Every file gets its own encryption key that only exists in your browser. We literally can't see your stuff.

When you upload a file, we generate a completely unique encryption key just for that file. This key is never stored anywhere and disappears when your session ends.

Encrypted Cloud Storage

Your files are scrambled before they hit our servers and stay scrambled the whole time.

We use Google Cloud Storage with Customer-Supplied Encryption Keys (CSEK), meaning even Google cannot access your files without the encryption key.

Auto-Delete (Like Browser History)

Files get deleted faster than your browser history. Processing done? Gone.

Your files are temporarily stored only during processing and are permanently deleted from our servers immediately after you download them.

We Can't See Your Files

Seriously, we tried. Built by paranoid developers who don't trust anyone.

We Can't See Your Files (Seriously)

Your files are encrypted with keys that only exist in your browser. Even our developers can't peek at your content.

Your Files Get Deleted Fast

Files stick around only while we're processing them, then poof - gone forever. Like they never existed.

Bank-Level Encryption

We use the same 256-bit AES encryption that banks use for their most secret stuff. Because your PDFs deserve it.

No Snooping, No Mining

We don't analyze, scan, or peek at your documents. We just fix them and mind our own business.

No Backdoors (We Promise)

There are no master keys or secret ways in. Once your session ends, your files become permanently unreachable.

Privacy by Design (Built Right)

Our security practices follow privacy-first principles because protecting your data is what we do (and it's the right thing to do).

100%
Privacy compliance
AES-256 because we take security seriously

Our security isn't just marketing talk. Every claim here is backed by real technical implementation. Your files deserve the same protection that banks use for their most sensitive data.

Security Questions

Questions people actually ask (not the corporate fluff)

Nope! Here's the nerdy explanation: your files get encrypted with a key that only exists in your browser session and is never stored on our servers or Google's servers. Without this key, the files are just scrambled nonsense. Even if our CEO really, really wanted to see your tax documents, they literally can't.

Technically impossible. The encryption keys live in your browser and vanish when you close the tab. Even if someone hacked our servers, they'd only find encrypted gibberish. It's like having a safe with no key - just a very expensive paperweight.

Your files get nuked from our servers immediately. Like, gone-gone. The encryption keys also self-destruct when your session ends. There's literally no way to recover them after that. We don't keep backups, copies, or anything.

Yep! During processing, your files are decrypted only in the server's memory (RAM) for the few seconds we need to do the work. It never touches the hard drive unencrypted. Think of it like doing surgery in a sterile room - exposed only when necessary.

If your connection drops, the partial file and encryption key get auto-deleted for security. You'd need to start over with a fresh upload and new key. Annoying? Yes. Secure? Also yes.

We keep basic tech logs like "someone processed a file at 3:47 PM" for debugging, but never filenames, content, or anything that could identify your documents. These boring logs get auto-deleted after 30 days anyway.
