Vaultline encrypts your files on your device before they ever leave it. We store only ciphertext — no passwords, no plaintext, no master key on our side. Even we can't read your data.
Strong encryption shouldn't mean friction. Vaultline runs quietly in the background, deduplicates and versions automatically, and keeps the keys where they belong: with you.
Every file is encrypted on your device with keys derived from your passphrase. Ciphertext is all that ever reaches our servers.
Set a folder once. Vaultline tracks changes in real time, uploading only the encrypted deltas to save bandwidth and time.
Roll back any file to any moment in the last 365 days. Ransomware and accidental deletes are a click away from recovery.
Generate per-file links with their own one-time keys, set an expiry, and revoke at any time. Recipients decrypt in the browser — your master key never travels.
From a fresh install to a fully encrypted, continuously backed-up vault in under five minutes.
Your passphrase generates the keys locally with Argon2id. It never leaves your device and is never sent to us — so only you can unlock the vault.
Choose what to protect. Files are chunked, deduplicated and encrypted before upload — we receive nothing but opaque ciphertext blocks.
Vaultline syncs in the background across all your devices, keeps a year of versions, and verifies integrity automatically every night.
Because keys are derived and held client-side, a server compromise exposes only encrypted blobs. No master key, no password hashes you'd worry about, no plaintext index. Privacy is structural, not a policy you have to trust.
Every tier ships full zero-knowledge encryption. You only pay for space and reach.
"We moved our entire research archive to Vaultline. The fact that the provider literally cannot read our data made the compliance review the easiest one we've ever passed."
