Real Deletion
When you delete, it's gone
What people store privately
Files that should stay yours alone.
Client & Project Files
Keep sensitive client documents under your own keys. No vendor can be compelled to hand them over because we can't read them.
Get NotifiedBackups & Off-Site Storage
Store encrypted backups on an independent network. When you delete, the file is gone. No residual copies, no recovery by anyone.
Get NotifiedPrivate Documents
Store personal files, financial records, and anything private. Encrypted before it leaves your device. Only you hold the key.

No. Zero-knowledge encryption means your files are encrypted before they leave your device. We never see the unencrypted data, and we don't hold your key. Neither do the Sia storage hosts. They only store encrypted fragments.
Anything private: backups, documents, databases, files of any kind. Access it through apps in the Sia ecosystem, or with S3-compatible tools you already use. Your files are encrypted on your device before they're sent to the Sia network, and decrypted on your machine when you download them.
Any app built on the Sia network. There isn't a single app directory yet. Sia ecosystem developers build apps that use the same encrypted storage layer. If you already use S3-compatible backup software or file managers, those work too. As more developers build on the platform, more apps become available.
Your file is split into encrypted fragments and spread across independent hosts. No host ever has a complete copy. When you delete, the contract payments stop and hosts drop their fragments. The file can't be reconstructed because the fragments no longer exist anywhere.
If you lose your encryption key, your data cannot be recovered by anyone. That's the trade-off of true zero-knowledge encryption: no backdoors, no recovery, no exceptions. Keep your key safe.
