Private cloud storage. Readable only by you.
Back up your photos, documents and everything you would never put in a normal cloud. Files are end-to-end encrypted on your device, so we only ever hold ciphertext.
10 GB free · No card required
Every photo backed up. Readable only by you.
Turn it on once and new photos back up by themselves. Each one is encrypted on your phone before it leaves, so nobody else can look at them, not even us.

“I chose ShieldFive because it doesn't just promise privacy—it implements the post-quantum cryptography (PQC) necessary to protect data against future threats.”
What can your cloud read?
Most storage encrypts your files with keys the company holds. ShieldFive encrypts them on your device, so we only ever store the encrypted version.

|---|---|---|---|
| Encrypted on your device before upload | Yes | No | Yes |

Checked 15 October 2026 on each provider’s own site. Google Drive and Dropbox offer client-side encryption only as an opt-in on some business plans. Proton Drive clients can upload through a shared folder link with edit rights, not an upload-only request. Proton’s post-quantum keys are opt-in and launched in Proton Mail.

Fair questions.
Can ShieldFive see my files?
Not their contents. Files are encrypted on your device before upload, and our servers store only the encrypted version. Sign-in and some operational metadata stay visible to us; the Security page lists exactly what.
What happens if I forget my password?
Keep your recovery key somewhere safe. It restores your vault when you reset a forgotten password. Without it, a reset cannot bring back files that are already encrypted.
Can I pay once instead of monthly?
Yes. The Founding Lifetime is one payment for 5 TB, for 99 years or your lifetime, whichever is shorter. You can still export every file whenever you like.
Is the free plan really free?
Yes. 10 GB of encrypted storage, no card and no time limit. Pay only when you need more space or firm features.
Can I use it on my phone?
Yes, in any mobile browser: the web app works now. The Android app is available on Google Play and the Mac app is available now; iOS and Windows remain in testing.
