All Features

Use the cloud. Don't trust it.

Sync via Google Drive or iCloud — but encrypted end-to-end before upload. Your cloud provider sees only gibberish. Use their infrastructure, keep your privacy.

Use the cloud without trusting it

PrivStack encrypts everything locally before uploading to your cloud storage. Your cloud provider stores only encrypted blobs. They can't read your data — and neither can we.

Convenience vs. privacy

Sometimes you need cloud sync for convenience or backup. But uploading your data unencrypted means trusting Google, Apple, or Microsoft with your private information.
