Calculator Hide App’s intruder selfie is one of its most powerful security features — and one of the least used, simply because people don’t know how to turn it on. Here’s what the feature does and here’s exactly how to enable and use it.
What the Intruder Selfie Does
Every time someone enters an incorrect PIN on the Calculator Hide App keypad, the front camera silently takes a photo of whoever is holding the phone. The photo is timestamped and saved inside the vault — accessible only to you. The person attempting entry has no idea a photo was taken.
How to Enable Intruder Selfie
- Open Calculator Hide App and enter your PIN.
- Inside the vault, go to Settings.
- Find “Intruder Selfie,” “Break-In Alert,” or “Security” — depending on your app version.
- Toggle the feature on.
- Grant camera permission if prompted. Calculator Hide App needs front camera access for this feature.
- Set the number of incorrect attempts before a photo is taken — most users choose 1 or 2.
That’s it. The feature is now active. Any wrong PIN attempt will silently trigger the front camera.
Where to Find Intruder Selfie Photos
Inside the vault, go to the Security or Intruder Selfie section. Captured photos are listed there with the date and time of each attempt. The photos are stored only inside the encrypted vault — they do not appear in your regular gallery.
Getting the Most from Intruder Selfie
- Set the trigger to 1 attempt for maximum sensitivity — anyone who enters the wrong PIN once gets photographed.
- Check the intruder log regularly, especially if you notice unusual activity on your phone.
- The feature works even when the phone screen is locked, as long as the attempt is made on the Calculator Hide App screen.
- If you have multiple vaults, the intruder selfie captures attempts on all vault PINs.
Intruder Selfie and Camera Permissions
Calculator Hide App needs camera permission to use the intruder selfie. On Android, you can set camera permission to “Only while using the app” or “Allow all the time.” For intruder selfie to work even when the app is in lock screen mode, set it to “Allow all the time.”
Frequently Asked Questions
Does the person know their photo was taken?
No. There is no flash, no shutter sound, and no notification visible to the person entering the wrong PIN. The photo is taken silently and stored inside the encrypted vault.
What if the front camera is covered?
The photo will be dark or obstructed. This is uncommon in practice — most people hold a phone normally when attempting to unlock it.
Can I share an intruder selfie with law enforcement?
Yes. You can export an intruder selfie photo from the vault to your gallery or share it directly from the vault’s share function. The timestamp is preserved in the image metadata.
