Filum

End-to-end encrypted vault

Your documents,
cached and sealed.

Filum keeps the documents you can't afford to lose behind end-to-end encryption. Everything is sealed on your device before it reaches us — only you hold the key.

How your key works

Encryption happens on your device.

Filum encrypts every file with AES-256-GCM before it leaves your device. We only ever store ciphertext — so a breach of our servers reveals nothing.

  1. 01 Your file, on your device
  2. 02 Sealed with AES-256-GCM · key never leaves
  3. 03 We store only ciphertext

Only you hold the key

Your key is derived on your device and never sent to us. Lose us in a breach and your files stay unreadable.

Everything in one place

IDs, deeds, contracts, recovery codes — cached where you can always find them.

Yours to keep

Export the whole vault any time. No lock-in, no hostages.

256 bit

AES-256-GCM authenticated encryption on every file.

Open core

Filum's encryption core, filum-crypto, is open source — read it, don't take our word.

Zero-access by design

What we can't see.

End-to-end means the vault is sealed before it reaches us. Here's exactly where that line falls.

Capability You Filum
Read your documents Yes Never
Hold your encryption key Yes Never
Export the whole vault Yes —

Keep what matters, sealed.
