Back up your clients' data in a vault only they can open.
Their data. Their keys. Your reputation.
Four guarantees you can show your clients — not just promise them.
Write once, delete never
Uploaded files cannot be modified or deleted — not by you, not by ransomware, not by anyone. Backups stay intact, period.
Write-only API keys
You push backups. That's it. No read access, no delete. And your client can cut your access with one click if they ever need to.
A passphrase only they know
Your client holds a 12-word secret passphrase. Without it, nobody can decrypt their files — not you, not us, not a court order.
One vault per client
Each client gets their own encrypted space. Fully isolated, independently auditable, accessible 24/7.
The best backup is the one your client can recover without you.
Three steps.
Sign up, set up your client's vault, invite them. Done.
Create your account
Sign up in seconds. A sandbox bucket lets you test the full workflow — API upload and passphrase download — before adding your first client.
Set up your client's vault
Add your client, create their encrypted buckets. You receive write-only API keys and start pushing backups immediately.
Invite them — they own it
Your client gets an email, receives their secret passphrase, and can access their files anytime. Even years from now. Even without you.
Three encryption layers. Zero trust required.
Your clients don't have to trust you. Or us. The math does the work.
File encryption
AES-256-CBCEvery file gets its own unique encryption key. Military-grade standard, used by governments worldwide.
Key protection
RSA-2048-OAEPEach file key is locked by the vault's public key. Only the data owner's private key can unlock it.
Master key
BIP39The data owner's private key is protected by a 12-word passphrase only they know. Easy to remember. Impossible to guess.
True zero-knowledge
We never see the passphrase, the keys, or the data. Even under a court order, we physically cannot decrypt your clients' files. That's not a policy — it's architecture.
