WhatsApp Chat Vault for USB-C Drives
No. VaultSap never logs into WhatsApp. It only works with .zip files you manually export using WhatsApp's own "Export Chat" feature. Your WhatsApp account is never at risk.
Any USB-C external drive that iOS can see in the Files app works with VaultSap. This includes ORICO, SanDisk, Samsung T7, WD My Passport, and similar drives. The drive should be formatted as ExFAT, FAT32, or APFS.
Yes. VaultSap stores backups locally on your iPhone even without an external drive. However, USB-C drive storage is recommended for large media archives and as a physical backup you can access from any computer.
This usually happens when the app's sandbox permission to read the drive has expired. Tap "Reconnect Drive" in the diagnostic card and select the drive using the file picker. This grants fresh read access.
Yes! Export your important chats on your Android phone (same menu: More → Export Chat → Include Media), save the .zip files to Google Drive or a USB-C drive, then share them into VaultSap on your new iPhone. Check the in-app "How It Works" guide under Settings for detailed steps.
Yes. VaultSap writes standard folders to the USB-C drive. Plug the drive into any computer and browse the VaultSap folder - each chat has its own subfolder with a text file and all media.
Re-export the same chat from WhatsApp and share it to VaultSap again. The new export will be imported as a separate timestamped backup. A future update will add automatic deduplication.
No. VaultSap has no servers, no analytics, and no internet connection requirement. Your data stays on your device and your USB-C drive. See our Privacy Policy for details.
