MultiVault

A vault only you can open.

MultiVault encrypts your most private photos, videos, and files on your device — before a single byte ever leaves it. Not us. Not Google. Not hackers. That's not marketing — it's math.

🔐 True Zero-Knowledge Security

Every file is encrypted on your device with AES-256-GCM — the same standard used by banks and governments. Your password is never transmitted, never stored on any server, and never visible to the developer. If we wanted to read your files, we couldn't. That's the point.

📵 Zero Data Collection. Zero Trackers.

No analytics. No crash reports. No advertising SDKs. No third-party services watching how you use the app. Your activity stays on your device — always.

☁️ Encrypted Cloud Backup — Free

Back up your vault to your own Google Drive, encrypted end-to-end. Files are encrypted before they leave your phone — Google's servers only ever see unreadable blobs. Even filenames are encrypted. Every user gets free encrypted backup for up to 15 files, out of the box.

🗂️ Connect Up to 15 Google Drive Accounts

Organize multiple vaults across different Google accounts — personal, family, work, legacy. Free users connect 1 Drive. Pro users can add up to 15, each with its own encrypted vault.

💎 Free & Pro

Free: 15 files with encrypted cloud backup, 1 Google Drive, all core features — no commitment, no ads.

Pro: A one-time purchase unlocks additional vault slots (up to 15 Drive connections) and unlimited file storage. No subscriptions. No recurring fees. Ever.

The bottom line: MultiVault is built on one principle — your private files should be yours alone. No backdoors. No recovery keys held by anyone else. No data leaving your device unencrypted. If you forget your password, we can't help you recover it — because we genuinely have no way in.

That's not a limitation. That's the feature.
