SIM Vault: Contacts Offline

Back up contacts into an on-device vault and beam them straight to your other phone over your own Wi-Fi. Encrypted, device to device. No internet. No account.

Your contacts, your devices. Nothing leaves them.

SIM Vault keeps contact backups entirely on your iPhone and moves them straight to your other devices over your own Wi-Fi — the internet is never involved.

VAULT — BACKUPS THAT STAY YOURS Select any contacts and save them as named snapshots inside the app. Snapshots never sync, never upload, and are excluded from iCloud backup.

TRANSFER — DEVICE TO DEVICE, ENCRYPTED, OFFLINE Send a snapshot straight to SIM Vault on your other phone. Both devices on the same Wi-Fi (or one device's hotspot), a shared 6-digit verification code on both screens, end-to-end AES-256 encryption. Done in seconds.

EXPORT & IMPORT vCard (.vcf) and spreadsheet (.csv) via the share sheet and Files.

WHAT SIM VAULT DOES NOT DO No ads. No analytics. No account. No cloud. No internet access to your data.
