Both apps use the same AES-256 encryption and security features. The key difference is how they sync:

FamiVault Link (recommended) syncs through an encrypted cloud relay — so family members can share documents from anywhere, even across cities or countries. Files are encrypted on your device before upload and automatically deleted from the cloud after delivery.

FamiVault uses local-only sync over WiFi or mobile hotspot — no data ever touches any cloud server. Perfect for families who want absolute zero cloud dependency.

Yes — extremely. Files are encrypted with AES-256 on your device before they leave it. The cloud relay only ever sees scrambled bytes — no filenames, no content, no metadata. Once the file is delivered to the recipient, it is automatically purged from the cloud. The encryption keys never leave your device.

FamiVault: Never. Zero cloud dependency — all sync happens directly between devices on the same WiFi or hotspot.

FamiVault Link: Encrypted data temporarily passes through a secure cloud relay for delivery, but is automatically deleted after sync. The cloud never sees your actual files — only encrypted bytes.

The vault owner generates a one-time QR invite code. In FamiVault Link, family members can scan it from anywhere. In FamiVault, they need to be on the same WiFi or hotspot. The owner must explicitly approve the join request.

Both apps have the Backup Vault feature. The vault owner can back up the entire vault to trusted family members, protected with a dedicated password. If you lose your phone, simply restore from a trusted family member's backup.

We recommend FamiVault Link for most families — it gives you the same security with the added flexibility of syncing from anywhere.

Choose FamiVault if you're extremely privacy-sensitive and want absolute zero cloud dependency — understanding that sync only works when devices are on the same local network.

Yes! Both FamiVault Link and FamiVault are available on iOS and Android. Family members can mix and match — an iPhone user and an Android user can both be part of the same vault.

FamiVault works on both home WiFi and mobile hotspot. Simply turn on your phone's hotspot and have family members connect to it. FamiVault Link doesn't have this limitation at all — it syncs from anywhere.
