SIM Vault is the privacy-first successor to SIM Manager. Keep contact backups entirely on your phone and move them straight to your other devices over your own Wi-Fi or Bluetooth — without the internet. Named snapshots never sync or upload. Every transfer is end-to-end encrypted (ECDH + AES-256-GCM) and confirmed with a 6-digit code. Export and import vCard and CSV. No ads, analytics, account, or cloud.

Key Features
Vault — backups that stay yours
Save contacts as named snapshots inside the app. They never sync, never upload, and are excluded from system cloud backups.
Encrypted device-to-device transfer
Send a snapshot over your own Wi-Fi or Bluetooth. End-to-end encryption with a 6-digit verification code — no internet, no relay server.
Export & import
vCard (.vcf) and spreadsheet (.csv) through the system file picker — compatible with Excel, Google Contacts, and iPhone.
No cloud. Ever.
No ads, analytics, account, or cloud. The only network traffic is the direct encrypted link between your own two devices.
