Guidance for using CalculatorOne+

CalculatorOne+ helps you keep selected photos and videos in a private local vault on your iPhone.

Getting Started

  • Create your app lock when you first open CalculatorOne+.
  • Import photos or videos from your library, or capture new items with the camera.
  • Use albums to organize private media stored inside the app.

WiFi Transfer

  1. Connect your iPhone and computer to the same trusted WiFi network.
  2. Open WiFi Transfer inside CalculatorOne+.
  3. Enter the displayed address in a browser on the other device.
  4. Keep the app open while transferring files, then stop WiFi Transfer when finished.

WiFi Transfer Troubleshooting

  • If the feature is unavailable, confirm your iPhone is connected to WiFi.
  • If the browser cannot connect, make sure both devices are on the same local network.
  • Allow Local Network access for CalculatorOne+ in iOS Settings if prompted.
  • Some guest, public, VPN, or enterprise networks block device-to-device connections.

Common Questions

Does CalculatorOne+ upload my photos?

No. Vault content is stored locally on your device and is not uploaded to a developer-operated cloud service.

Why does Private Photos not show a preview?

The Private Photos album intentionally hides its preview thumbnail for additional discretion.

Can I rename or delete Private Photos?

No. Private Photos is a protected system album and cannot be renamed or deleted.

What happens if I delete the app?

Local vault content may be permanently removed. CalculatorOne+ is not a cloud backup service, so export important files or maintain an appropriate device backup.
